Why Does Being in the Sun Make You So Tired?

The video explains why being in the sun can make you feel tired. It highlights how the body works to protect itself from heat, dehydration, and UV damage. The body regulates temperature through sweating, which can lead to dehydration. High temperatures strain the heart and lungs, while UV rays can damage skin cells, potentially leading to skin cancer. The immune system works to repair this damage, causing fatigue. The video concludes with advice on cooling down and rehydrating to mitigate these effects.

Why does being in the sun make you feel more tired even if you're not moving?

• The sun causes your muscles to fatigue.

• Your body works hard to protect itself from heat and UV damage.

• The sun's brightness tires your eyes.

• The sun's rays directly drain your energy.

What is a potential consequence of your body overheating?

• Increased appetite

• Improved concentration

• Heat exhaustion

• Enhanced immune response

How does sweating help regulate body temperature?

• By increasing blood pressure

• By cooling the skin as sweat evaporates

• By reducing heart rate

• By increasing muscle activity

What happens to your heart when you are dehydrated?

• It stops working efficiently.

• It slows down to conserve energy.

• It pumps faster to compensate for decreased blood volume.

• It becomes more relaxed.

What is a 'fingerprint mutation' caused by UV rays?

• A mutation that enhances skin color

• A mutation that increases hair growth

• A mutation that substitutes cytosine for thymine

• A mutation that strengthens DNA
