1. You Lose Most of Your Body Heat Through Your Head

Myth: Most body heat escapes through the head.
Fact: Heat loss is proportional to the exposed skin surface. Your head isn’t a special heat escape zone; it only feels colder because it’s often uncovered.

2. Drinking Hot Liquids Warms You Faster Than Cold Liquids

Myth: Hot drinks raise your core body temperature quickly.
Fact: Hot drinks may feel comforting but can actually cause your body to lower its core temperature slightly. Hydration is key, regardless of liquid temperature.

3. Going Outside Without a Coat Will Make You Sick

Myth: Exposure to cold weather causes colds and flu.
Fact: Viruses cause illnesses, not cold weather. People tend to get sick more in winter because they spend more time indoors, increasing virus transmission.

4. Vitamin C Prevents Colds

Myth: Taking vitamin C supplements stops colds.
Fact: Vitamin C supports the immune system but does not prevent colds. A balanced diet usually provides enough vitamin C.

5. Women Are Colder Than Men

Myth: Women feel colder because their core temperature is lower.
Fact: Women’s core body temperature is generally higher, but their extremities may feel colder due to circulation differences.

6. Fluctuating Temperatures Make You Sick

Myth: Rapid temperature changes cause illness.
Fact: Illness is caused by viruses and bacteria, not temperature swings. However, people with asthma may experience symptoms during fluctuations.

7. You Always Need Antibiotics for the Flu

Myth: Antibiotics cure flu and colds.
Fact: Flu and colds are viral; antibiotics only work for bacterial infections, not viruses.

9. The Flu Is Just a Bad Cold

Myth: Flu symptoms are mild like a cold.
Fact: Flu can cause severe illness and complications, unlike the common cold.

10. If You’ve Had the Flu Vaccine, You Can’t Get the Flu

Myth: Flu shots guarantee full protection.
Fact: Vaccines reduce risk and severity but don’t guarantee complete immunity.

11. Sunscreen Is Not Needed in Winter

Myth: Sunscreen is only for summer.
Fact: UV rays reflect off snow and can cause skin damage even in winter; sunscreen is still necessary.

12. You Shouldn’t Exercise in Cold Weather

Myth: Cold air is harmful during exercise.
Fact: Exercise in winter is safe and can boost energy and mood.

13. Alcohol Warms You Up

Myth: Drinking alcohol helps you stay warm.
Fact: Alcohol causes blood vessels to dilate, increasing heat loss and lowering core temperature.

14. You Should Avoid Showering in Cold Weather

Myth: Showering in winter makes you sick.
Fact: Showering does not cause illness; viruses do. Good hygiene helps prevent sickness.

15. Hot Baths Cure Colds and Flu
