• Conduction
• Convection
• Radiation
• Evaporation

For example, when you sit on a cold metal bench, you feel cold because of conduction - heat flows from your warmer body to the colder bench.

Think about it! When you’re exercising, you sweat, and when that sweat evaporates, it cools you down. It's like your body's built-in air conditioner!

When cold, you shiver. This is your muscles producing heat by rapid contraction and relaxation. It’s like your body saying, “Brrr, let's warm up!”

• Heat Cramps: Painful muscle contractions due to dehydration and electrolyte imbalance.
• Heat Stroke: Serious business! High body temperature and dysfunction of the central nervous system. Requires immediate medical attention.

Drink plenty of water before and during exercise. Remember, once you're thirsty, you're already starting to dehydrate!

Over time, your body can adapt: better sweating, reduced salt in sweat, and improved blood circulation!

Our body traps air and reduces blood flow to the skin. It’s like putting on a warm coat to prevent the cold air from reaching your skin!

Losing 1% of body weight in fluids = Mild dehydration. Always hydrate!
