In a recent post, Dr Sudhir Kumar busted 10 common misconceptions people have about health. Health misconceptions occur very often, while you may not realize it; we also perpetuate these myths very often. To help people avoid these, Dr Sudhir Kumar, a Hyderabad-based Neurologist, listed misconceptions about common diseases. The reason why it is important to know what to believe and what not to, is because these myths can lead people to ignore obvious health signs, like signs of heart attacks, because they believe they are unlikely to get one themselves. 10 Health Myths You Should Not Believe Here are 10 common health misconceptions you should know about, according to Dr Sudhir Kumar. Myth: Stroke Only Happens to the Elderly. Fact: Stroke Can Happen at Any Age. Many people think strokes are just an old-age problem, but this is false. Strokes can strike young adults, even in their 30s or 40s. Having high blood pressure, diabetes, or smoking greatly increases the risk, regardless of your age. Staying healthy is crucial for everyone. Myth: Heart Attacks Always Cause Severe Chest Pain. Fact: Heart Attacks Can Be Silent or Mild. It’s a common belief that a heart attack is always a sudden, crushing pain. However, many heart attacks are mild or "silent," causing only slight discomfort or unusual fatigue. This is especially common in women and people with diabetes, making it easy to overlook. Myth: Fever Must Always Be Brought Down Quickly. Fact: Fever is Your Body's Natural Defense. Fever is how your immune system fights off infections. You only need to treat it if the temperature is dangerously high or if you feel very uncomfortable. For mild fevers, let your body do its job; focus on rest and hydration instead. Myth: Antibiotics Cure Colds and Flu. Fact: Antibiotics Only Fight Bacteria, Not Viruses. Colds and the flu are caused by viruses, and antibiotics are useless against them. Taking antibiotics unnecessarily will not help and actually makes them less effective against real bacterial infections later on. Only use them when prescribed for bacteria. Myth: High Blood Pressure Always Causes Symptoms. Fact: Hypertension is Usually a Silent Condition. High blood pressure (hypertension) is often called the "silent killer" because it rarely causes noticeable symptoms until it's very severe. This is why getting your blood pressure checked regularly is essential. You need routine checks to catch it early before it causes damage. Myth: Eating Sweets Causes Diabetes. Fact: Diabetes is Complex, Not Just Caused by Sugar. While eating too much sugar makes Type 2 diabetes worse, the disease is primarily caused by a mix of genetics, not exercising enough, and the body's inability to properly use insulin (insulin resistance). It is a lifestyle disorder, not just a sugar problem. Myth: Sunscreen is Only Needed on Sunny Days. Fact: Harmful UV Rays Get Through Clouds Daily. Many people skip sunscreen on cloudy or overcast days, but this is a mistake. Ultraviolet (UV) rays from the sun, which damage your skin, can easily penetrate clouds. You need to apply sunscreen every single day for proper protection against skin aging and cancer. Myth: Cancer Always Runs in Families. Fact: Lifestyle and Environment Cause Most Cancers. While certain rare cancers are linked to inherited genes, the majority of cancer cases are actually caused by daily habits and environmental factors. Things like smoking, diet, lack of exercise, and sun exposure play a much bigger role in cancer risk for most people. Myth: Once Symptoms Improve, You Can Stop Taking Medicines. Fact: Stopping Treatment Early Can Cause Relapse. You must always finish the full course of medicine as directed by your doctor. Stopping treatment too soon—especially antibiotics or blood pressure medication—allows the illness to come back or get worse. Follow the prescription to fully clear the infection or manage the condition. Myth: Mental Health Problems Mean Weakness. Fact: Mental Health Issues Are Real Medical Conditions. Conditions like depression or anxiety are genuine medical illnesses, just like diabetes or heart disease. They are not a sign that a person is weak or failing. Seeking help from a professional shows courage and strength, taking an active step toward recovery and well-being.
