CPR (Cardiopulmonary Resuscitation): Methods, Misconceptions, and Can You Perform It Without Certification?

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about CPR. Let’s dive in!

CPR (Cardiopulmonary Resuscitation) is the first and most effective emergency procedure for a person in cardiac arrest. It involves securing the airway, providing ventilation, and performing chest compressions to restore circulation. However, many people either do not know how to perform it correctly or panic in an emergency. Others hesitate because they lack certification, lack confidence, or fear legal consequences. Let’s debunk some common misconceptions about CPR.

---

Why Is CPR Essential?

The heart functions as a pump that supplies blood throughout the body. It continuously receives and distributes blood, ensuring vital organs like the brain, liver, and lungs get the oxygen they need. You can feel this process by placing your hand over your chest and sensing your heartbeat—each pump sends blood throughout your body.

If the heart stops, it can no longer supply blood to critical organs. The brain is particularly vulnerable; without blood flow, severe brain damage can occur. Even if the heart is later restarted, brain damage may cause lasting effects, making normal daily life impossible. The longer cardiac arrest continues, the higher the risk of a fatal outcome.

The key is how quickly a person in cardiac arrest receives CPR. Ideally, CPR should be performed within four minutes—this is known as the "golden time," and the faster it is administered, the higher the chances of survival.

How to Perform CPR

CPR is generally performed either by trained emergency responders or by bystanders who witness the incident. In most cases, it is bystanders who must take immediate action. If you witness someone collapse, follow these seven steps:

1. Check for a Response

• Ensure the area is safe from hazards.
• Gently tap the person’s shoulder and check if they respond.
• If there is no response, assume cardiac arrest.

2. Call 911

• Ask a specific person nearby to call 911. If alone, make the call yourself.
• If an Automated External Defibrillator (AED) is available, use it immediately.

3. Check for Breathing

• Observe the person's face and chest for breathing for up to 10 seconds.
• If there is no breathing or it appears abnormal, assume cardiac arrest.
• If untrained, follow guidance from the emergency dispatcher.

4. Perform 30 Chest Compressions

• Lay the person on a firm, flat surface.
• Kneel beside them and position yourself over their chest.
• Place the heel of one hand in the center of the chest, stack the other hand on top, and interlock fingers.
• Keep your arms straight and use your body weight to press down hard and fast.
• Perform compressions at a rate of 100–120 per minute, with a depth of about 5 cm (2 inches).
• Count out loud to maintain rhythm.

5. Provide Rescue Breaths (Optional)

• Tilt the head back and lift the chin to open the airway.
• If there are visible obstructions (e.g., vomit), remove them.
• Pinch the nose shut, take a deep breath, and blow into the person’s mouth for one second.
• Watch for the chest to rise, then let the air escape.
• If unsure or unwilling to perform rescue breaths, continue chest compressions only.

6. Repeat Compressions and Breaths

• Continue alternating between 30 compressions and two rescue breaths.
• Keep performing CPR until medical professionals arrive.
• If multiple people are present, take turns to prevent fatigue.

7. Recovery Position

• If the person starts moving or making sounds, check for normal breathing.
• If breathing is restored, turn them onto their side to prevent airway blockage.
• If they stop breathing again, resume CPR immediately.

Common Misconceptions About CPR

Q: Do I need certification or training to perform CPR?

A: No. Anyone can perform CPR, even without formal training. However, pressing the correct location on the chest is crucial for effectiveness. Learning the basic method in advance can be life-saving.

Q: Is CPR training expensive or only available in special institutions?

A: No. CPR training is often free and accessible online. Organizations like the Korean Association of Cardiopulmonary Resuscitation and the Red Cross offer free CPR courses, including in-person training sessions.

Q: Will I be punished if I break someone's ribs while performing CPR?

A: CPR requires strong chest compressions, and rib fractures can occur. However, if CPR is performed in good faith to save a life, legal protection is in place, and you will not be punished.

Q: What if the patient or their family sues me?

A: Even if a patient or their family files a complaint, laws like the “Good Samaritan Law” protect bystanders who provide emergency assistance. However, if unnecessary actions are taken when there is no emergency, legal consequences may apply.

---

The Importance of CPR

Many news reports highlight cases where CPR saved lives because bystanders acted quickly. However, some stories also describe legal disputes, which can discourage people from intervening. Even those trained in CPR may hesitate when faced with a real emergency.

Despite this, immediate CPR from a witness or bystander is the most effective lifesaving measure. It is a selfless act that can make the difference between life and death. Knowing CPR can help not only strangers but also our own family and friends in emergencies.

PTSD (Post-Traumatic Stress Disorder): Meaning, Symptoms, and Treatment

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about PTSD. Let’s dive in!

Experiencing a severe physical or psychological trauma can lead to a fear of similar situations happening again. For example, if someone almost got into a serious accident while alone, they might feel anxious whenever they are by themselves, even if no danger is present. Similarly, a person who has been bitten by a large dog may become fearful of even small puppies.

---

What is PTSD (Post-Traumatic Stress Disorder)?

Such symptoms are classified as Post-Traumatic Stress Disorder (PTSD) in mental health. PTSD is a condition in which a person experiences persistent fear and distress after going through a major traumatic event, such as war, torture, natural disasters, or severe accidents.

In recent years, the phrase “I feel like I’m getting PTSD” has become a common joke, but the actual condition is far from something to take lightly. PTSD can consume a person’s mental and physical energy as they struggle to escape the fear and pain caused by their traumatic experience. If left untreated, it can interfere with daily life and personal well-being.

---

Symptoms of PTSD

One of the main signs of PTSD is avoiding situations that resemble the traumatic event. For example, if someone was burned by hot water, they might develop a fear of hot water and prefer using cold water. If they were in a car accident in a narrow alley, they might take longer routes to avoid similar streets.

The severity of PTSD varies from person to person. Some may recover quickly, while others develop long-lasting symptoms. In some cases, PTSD symptoms appear immediately after the event, but in others, they can emerge months or even years later.

PTSD is not just about fear—it can also cause behavioral and emotional changes. Some individuals become more aggressive, struggle with impulse control, or experience depression and substance abuse. Cognitive issues like difficulty concentrating and memory loss may also occur.

---

Treatment for PTSD

If PTSD symptoms are present, or if psychological distress follows a traumatic event, seeking professional help is crucial. A psychiatrist will conduct an evaluation, discussing past medical history, recent traumatic experiences, and daily habits to make a diagnosis.

The most effective treatment is providing emotional stability and helping the person feel safe. Encouraging them to talk about the traumatic event can be beneficial, as PTSD is rooted in psychological distress. Addressing the underlying fears is a key part of the healing process.

Medication may also be prescribed by a doctor. These treatments can not only alleviate PTSD symptoms but also help with related conditions like anxiety and depression.

Psychotherapy is another essential treatment method. Various approaches, including psychodynamic therapy, behavioral therapy, cognitive therapy, and hypnotherapy, are used based on the patient’s condition.

---

How to Overcome PTSD

If someone recognizes their PTSD symptoms, seeking professional counseling as soon as possible is recommended. Self-diagnosing and ignoring symptoms can delay recovery and worsen the condition. However, some individuals avoid psychiatric treatment due to stigma or the belief that their condition is not severe enough.

Studies show that about 30% of PTSD patients recover without treatment, and around 40% experience symptom improvement over time. Having a strong support system—such as family or friends—can help some people naturally overcome PTSD without medical intervention.

However, if PTSD symptoms persist or worsen, professional help should be sought immediately. There are no specific dietary or lifestyle changes that can prevent PTSD. The key to recovery is how well a person can regain a sense of emotional stability when symptoms appear.

The Global War on Sugar: Start by Cutting Back on Sugary Drinks

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about Sugar. Let’s dive in!

The harmful effects of sugar are becoming as widely recognized as those of salt, leading global health organizations, including the World Health Organization (WHO), to actively work on reducing sugar consumption worldwide.

More than 80 countries have already introduced a “sugar tax”, imposing taxes on processed foods high in added sugars (such as sugar, honey, syrup, and high-fructose corn syrup). This tax treats sugar as harmful as alcohol and tobacco.

For example, the UK introduced a sugar tax in 2018:

• Less than 5g of added sugar per 100mL → No tax
• 5–8g of added sugar per 100mL → £0.18 per liter tax
• More than 8g of added sugar per 100mL → £0.24 per liter tax

As a result, the total sugar content in UK children's sugary food products decreased by 2.9% per 100g.

Similarly, Mexico implemented a sugar tax in 2014, charging 1 peso per liter (approximately $0.05) on all sugary beverages. This policy led to a decline in sugary drink purchases, particularly among low-income populations.

---

How Much Sugar Should You Consume?

Excessive sugar intake is a major cause of obesity, which is known as the root of many diseases. Obesity increases the risk of:

• High blood pressure
• Diabetes
• High cholesterol
• Fatty liver disease
• Heart disease
• Stroke
• Certain types of cancer

The World Health Organization (WHO) recommends keeping added sugar intake below 10% of total daily energy consumption and ideally below 5% for additional health benefits.

Other guidelines include:

• UK Health Department → Less than 5% of total energy intake
• U.S. Department of Agriculture (USDA) → No added sugar at all for children under 2 years old; less than 10% for ages 2 and above
• South Korea → Less than 10% of total energy intake

But how much sugar is that in reality?

• If your daily calorie intake is 2,000 kcal, the recommended limit is less than 50g of added sugar (5 tablespoons).
• For even better health, 25g or less is ideal.

This limit is easy to exceed. For example:

• One instant coffee mix contains 11g of added sugar
• One bottle of cola contains 23g of added sugar
• One serving of ice cream contains 17g of added sugar

Just consuming these three items together exceeds the daily 50g limit.

---

Cut Back on Sugary Drinks

The biggest contributor to excessive sugar consumption is beverages.
Many people underestimate how much sugar is hidden in drinks—not just in soda and instant coffee mixes, but also in café-made drinks.

Added sugar content per drink (Tall size, according to USDA 2020):

• Lemonade → 43g
• Café Mocha → 23g
• Chai Tea Latte → 23g
• Fruit Juice → 59g

Drinking just one of these beverages can bring you close to the daily sugar limit. When combined with the other foods you eat throughout the day, sugar intake can easily exceed healthy levels.

What about "healthy" sugar drinks like brown sugar bubble tea? Unfortunately, sugar is sugar, no matter the source.

• The average brown sugar bubble tea contains 34.8g of sugar, even more than cola.
• That is equivalent to 12 sugar cubes (3g each).

Experts, including the American Diabetes Association, warn that excessive sugar intake—whether from white sugar, brown sugar, honey, or agave syrup—has the same negative health effects.

Even fruit juice is not as healthy as many believe.

• Blended fruit juice lacks fiber, causing a rapid spike in blood sugar.
• Excess sugar from fruit juice is converted into fat, leading to weight gain.
• Experts from the American Heart Association, American Academy of Pediatrics, and the Academy of Nutrition and Dietetics strongly advise against giving children under 5 sugary drinks, including fruit juice, to prevent childhood obesity.

---

Drink Water Instead

The best way to cut back on sugar is to drink water instead of sugary drinks.

The World Health Organization (WHO) suggests a minimum daily water intake of about 5.3 liters per person in certain conditions, though individual needs vary based on factors like age, gender, climate, and activity level. General recommendations from health organizations suggest about 3.7 liters (13–15.5 cups) for men and 2.7 liters (9–11.5 cups) for women, including fluids from both food and beverages. Since about 20% of daily fluid intake comes from food, aiming for around 2 liters (8 cups) of water from beverages daily is a reasonable goal for most people.

Reducing sugary beverages is one of the easiest and most effective ways to improve overall well-being. Start today—your body will thank you.

The Common Cold of the Mind: Causes and Symptoms of Depression

 

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about Depression. Let’s dive in!

Depression is often referred to as the common cold of the mind. It can affect anyone and, in some cases, may be overcome easily. However, if left untreated, depression can seriously impact personal relationships and social life.

---

What Causes Depression?

Studies on monthly patient trends over the past few years show that depression is at its lowest in February but steadily increases from March as spring begins.

During winter, our bodies are less exposed to sunlight and become accustomed to colder temperatures. When spring arrives, the increase in daylight hours causes changes in the brain’s biological clock, which regulates sleep and hormones. This sudden shift can create an imbalance, leading to depression.

Additionally, those who already experience mild sadness or lack physical readiness for increased activity in the warmer season may be more prone to developing depression.

---

Recognizing the Symptoms of Depression

Based on clinical observations, depression manifests in the following physical and emotional symptoms:

 Physical Symptoms

• Changes in appetite → Weight loss due to decreased appetite or weight gain from emotional overeating.
• Fluctuating body temperature → Feeling hot and cold alternately.
• Nerve and muscle discomfort → Tingling, swelling in hands and feet, and a sense of tightness in the chest.
• Chronic pain → Frequent neck, shoulder, and head pain, sometimes accompanied by severe migraines.
• Digestive issues → Persistent indigestion and constipation, causing discomfort.

 Emotional Symptoms

• Persistent sadness, helplessness, and loss of motivation.
• Lack of interest in previously enjoyable activities.
• Irritability and extreme fatigue.
• Insomnia and trouble sleeping.
• Difficulty focusing, remembering things, or making decisions.
• Feelings of worthlessness, guilt, or self-blame.

---

Seeking Help

If you experience these physical or emotional symptoms, it’s important to seek professional help as soon as possible. Depression is a medical condition, not just a passing mood. Early treatment can prevent it from worsening and help you regain a healthy, balanced life. 💙

4 Ways to Relieve Stress and Take Care of Your Mind

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about How to Relieve Stress. Let’s dive in!

Everyone carries some level of worries, stress, and anxiety—whether it's about relationships, the future, financial struggles, health issues, or work-related pressure. In winter, with less sunlight, these feelings of unease and sadness can intensify.

On the other hand, spring—when trees start budding and nature awakens from the cold—has the power to refresh our minds and prepare us for new beginnings. To embrace this season, The New York Times shared ways to clear your head and give your mind a break.

---

1| Practicing Mindfulness Meditation

One effective way to find inner peace is through mindfulness meditation. People often feel stressed and anxious when dwelling on the past or worrying about the future. Mindfulness meditation helps clear your thoughts and focus on your breathing and present moment, reducing daily stress.

Even a short 5-minute meditation in the morning, before bed, or during stressful moments can relieve tension and anxiety. If you're new to meditation, try using YouTube tutorials from experts or download meditation apps to guide you.

---

| Writing a Journal

Keeping a journal is another great way to heal your mind. Writing down thoughts and emotions helps you see your situation more clearly and evaluate whether you're using your time and energy wisely.

By rereading your journal, you can identify mistakes, understand your emotions better, and plan for the future. Also, recording happy and fulfilling moments helps you recognize what truly brings you energy and pride.

If journaling feels unfamiliar or overwhelming, start with just one or two sentences a day. Simply jot down what happened that day or how you felt—no need to write daily. The key is to develop a habit gradually.

---

| Reducing Information Overload

Another way to relieve stress is by limiting the amount of information you consume. With smartphones, we constantly absorb news from social media, YouTube, and online articles. While some information is useful, a lot of it can lead to anxiety, anger, or a sense of helplessness.

Cal Newport, a Georgetown University professor and author of Digital Minimalism, advised in a New York Times interview:
“Be mindful of your news consumption. Choose one or two reliable sources and set a fixed time for reading the news.”

Instead of automatically opening Instagram, TikTok, or YouTube during free time, try activities that truly relax your mind—such as reading a book, listening to music, or taking a walk. This prevents information overload and keeps your brain refreshed.

---

| Organizing Your Space

Cleaning and decluttering your environment can instantly boost your mood. Professor Catherine Anderson of the University of New Mexico states:

“A cluttered space tends to disrupt clear thinking.”

A tidy and organized space can improve productivity and focus, and even the process of cleaning itself can give you a sense of accomplishment and energy.

---

By practicing these simple habits, you can relieve stress and refresh your mind, making every season—especially spring—a time of positivity and renewal.

Basic Emergency CPR: The Faster, the Higher the Survival Rate

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about CPR. Let’s dive in!

Performing CPR within 1 minute, 2 minutes, or 4 minutes results in survival rates of 97%, 90%, and 50%, respectively. However, after 10 minutes, brain cells begin to die almost completely.

Let’s go over the correct way to perform CPR.

---

Adult CPR Procedure

If you find someone unconscious, shake their shoulders and ask, "Are you okay?" to check for a response. If the person responds by moving, speaking, or making sounds, they are conscious. However, if they don’t respond or their breathing is abnormal, it is likely cardiac arrest, and you must immediately call 911.

If others are nearby, point to someone and tell them to call 911 and bring an AED (Automated External Defibrillator) if available. If you’re alone, shout loudly for help to see if anyone is around to assist.

Ambulances are equipped with life-saving equipment and trained personnel, so calling 911 is the most critical step.

When calling 911, provide the following details:

• Location of the emergency
• What happened
• Patient’s condition
• Current first aid being performed

If possible, turn on speakerphone so the 911 dispatcher can guide you through CPR. Stay on the call until they instruct you to hang up.

---

Performing Chest Compressions

After calling 911, begin chest compressions. The 2015 CPR guidelines suggested placing the patient on a flat, firm surface, but 2020 guidelines now recommend performing CPR on a bed if moving the patient to the floor is difficult.

Additionally, if the airway is blocked by an object and the person cannot cough effectively, the 2020 guidelines recommend trying back blows first and then performing abdominal thrusts (Heimlich maneuver) if needed.

For chest compressions:

1. Place the heel of one hand on the lower half of the breastbone.
2. Place the other hand on top, keeping fingers interlocked and off the chest.
3. Keep arms straight and position shoulders directly over the hands for effective pressure.
4. Press hard and fast at a rate of 100–120 compressions per minute, pressing at least 2 inches (5 cm) deep.

This force helps pump blood to the brain. In CPR, anyone over age 8 is treated as an adult.

After 30 compressions, provide 2 rescue breaths as follows:

1. Tilt the person’s head back to open the airway.
2. Pinch their nose shut and place your mouth over theirs to form a seal.
3. Take a normal breath and blow into their mouth for 1 second, ensuring the chest rises.

Continue with the 30 compressions → 2 breaths cycle without long pauses, as any delay stops blood flow to the brain. If you’re unsure how to give breaths, continue chest compressions only without stopping.

---

CPR with Two Rescuers

If two people are performing CPR:

• One person should continue chest compressions, while
• The other provides 2 rescue breaths every 30 compressions.

Since chest compressions are physically exhausting, switch roles every 2 minutes to maintain effectiveness.

According to the 2020 guidelines, basic CPR should continue for 6 minutes, and advanced life support teams should provide care for up to 10 minutes before transporting the patient to a hospital.

Continue CPR until the ambulance arrives and emergency responders take over.

---

Using an Automated External Defibrillator (AED)

If an AED arrives:

1. Turn it on and follow the voice instructions.
2. Attach the electrode pads to the patient’s chest.
3. Allow the AED to analyze the heart rhythm and follow its directions.

If a shock is needed, the AED will guide you through the process. Continue CPR between shocks as directed.

---

CPR Awareness & Survival Rates

Thanks to efforts by the U.S. Department of Health and Human Services, the CDC, and the American Heart Association, public CPR training rates have significantly increased.

This has led to higher survival rates for sudden cardiac arrest, with more patients regaining full brain function after recovery.

However, there’s still room for improvement. Every year, over 350,000 out-of-hospital cardiac arrests occur in the U.S., yet bystander CPR rates remain low.

To compare:

• Sweden: 55% of cardiac arrest cases receive bystander CPR
• U.S.: 30.8%

More resources on CPR can be found on the CDC website (www.cdc.gov).

A single hour of training can help you save a life—whether it’s a family member, a friend, or even a stranger.

---

Making CPR a Habit

To spread awareness, post CPR instructions in common areas or hallways at home, work, or school.

Final reminder: If someone loses consciousness, CALL 911 IMMEDIATELY and perform chest compressions until help arrives.

Learning CPR could save someone’s life—and one day, someone else might save yours.

Are You Addicted to Dopamine from Watching Short-Form Videos?

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about Short-Form, Dopamine. Let’s dive in! 

Recently, more and more people are hooked on short-form videos.

Many start their day by grabbing their smartphones and watching short videos in bed. Some even set up phone stands around the house to keep watching while moving from room to room. It’s common to see people watching short-form content even while brushing their teeth.

---

What is Short-Form Content?

Short-form videos are bite-sized clips, typically under one minute long, distributed through social media platforms like Instagram, YouTube, and TikTok.

These videos have captivated modern smartphone users, and among young adults in their 20s and 30s, the term "dopamine addiction" has become a trending phrase. One of the biggest contributors to this phenomenon is short-form content.

Since these videos deliver entertaining or essential content in a highly condensed and stimulating way, they naturally trigger a dopamine rush. This is why people say watching short-form content feels like "recharging their dopamine."

---

What is Dopamine?

Dopamine is a neurotransmitter released in the brain when we experience something new or exciting.

Recently, the term dopamine addiction has been used to describe short-form video addiction, making dopamine sound like a problem. However, dopamine itself isn’t bad—it plays a crucial role in happiness and neural stimulation. A lack of dopamine can lead to conditions like depression and Parkinson’s disease.

The real issue arises when dopamine is released excessively.

When our brains repeatedly receive the same kind of stimulation, they start craving stronger and more intense stimuli. Over time, the standard for excitement rises, making everyday joys feel dull. For example, instead of finding happiness in meaningful conversations over a meal with family, people may only feel excitement from consuming fast-paced, stimulating short-form content. This pattern leads to addiction—similar to what happens with gambling, gaming, or overeating.

---

The Dopamine Detox Movement

The issue of dopamine addiction from short-form content has gained attention worldwide, leading to the rise of dopamine detox—a method of breaking free from overstimulation and rediscovering simple pleasures. Since excessive dopamine release can harm focus and concentration, finding balance is essential.

Some extreme forms of dopamine detox involve completely eliminating smartphone use. A popular method includes locking phones in a timed box that only opens after a set period. Others opt for digital detox retreats in nature, where smartphone use is strictly prohibited.

---

Practical Ways to Do a Dopamine Detox

For most people, completely avoiding smartphones isn’t realistic due to daily responsibilities and constant communication needs. Instead, making small, manageable changes can help break the cycle of overstimulation.

If you've ever lost track of time watching short-form videos, consider setting usage time limits with an alarm. You can also balance out stimulating activities like gaming or binge-watching by taking breaks to read or exercise. These small steps can help your brain reset and regain control over dopamine release.
