 But I always forget how exhausted I feel when I go home from being in the sun. I need a big one. There are actually scientific reasons that explain the tired phenomena after the sun that most of us experience.

# 1. Body temperature

Scientists say that the sun's energy transfers heat to the body by electromagnetic radiation in the form of photons. This radiation causes your body temperature to rise. When your body temperature changes by more than 0.5 degrees, your body reacts by being sleepy, groggy, or tired. This reaction is important for children.

While we are in the sun, our bodies have to work hard to regulate our body temperature. The higher the outside temperatures and the bigger the body, the harder it has to work. Our body obviously works hard to cool us down and uses a lot of energy and other resources, including sweat. Sweat helps cool the body by evaporating water from the skin. This process draws energy from our body. Also, at high temperatures, our heart rate and metabolic systems increase, making our bodies much harder. All this invisible work makes us feel sleepy and exhausted.

# 2. Chemistry

Some scientists suggest that being in the sun suppresses melatonin production. Then, after leaving the beach, melatonin production increases, which strongly pushes us to take a good nap. Being in the sun causes an increase in some very good vitamins, but this increase reduces metabolic effort and drains energy. Ultraviolet light triggers a series of chemical reactions that can eventually cause drowsiness and lethargy.

We all know that the sun's ultraviolet rays can penetrate the skin and cause damage such as wrinkles, sunburn, and cancer. The abundance of chemical actions that cause these effects can also cause sun fatigue after hours.

# 3.Light

In bright sunlight, the sleep/wake cycle is interrupted. The sun sends signals that change the day/night rhythm. Sun exposure can reset your watch. Our bodies believe that the day is awake and the night is asleep. People who do not get enough sunlight often suffer from insomnia.

# 4. Extreme heat makes you tired

Extreme sun exposure can cause dangerous dehydration as your body sweats and you lose water. Symptoms of dehydration include dry mouth, drowsiness, lethargy, thirst, dry skin, headaches, and dizziness.

Extreme heat can also cause heat exhaustion. Symptoms of heat exhaustion include skin that feels cool to the touch when exposed to heat, intense sweating, dizziness, exhaustion, weak pulse, postural hypertension, convulsions, headache, and nausea. These conditions may require medical attention and you should seek help immediately if symptoms are extreme.

Sun Exposure Recommendations

By protecting ourselves from the sun, we can also lessen the tiring effects of the sun.

1. Do not stay in direct sunlight for too long.

2. Food and drink 

 Drink plenty of water and eat a salty snack to replace the salt and water in your sweat.

3. Shade 

 Reduce the risk of skin damage by bringing an umbrella to the beach or finding a shade tree to sit under. Wear protective clothing including a hat.

4. Clothing 

 Between swimmers, wear a long-sleeved shirt and pants or skirt covering exposed skin to be protected from harmful UV rays. Darker colors and clothing with tighter knits offer the best protection.

5. Hat

 Wear a hat with a wide brim that goes everywhere so it shades your face. As with clothing, densely woven hats and dark hats offer a little more protection. If you have a baseball cap, don't forget to use sunscreen on your ears and neck.

6. Sunglasses

 Wear sunglasses to protect your eyes from UV rays that can cause cataracts. The sore skin around your eyes needs to be protected from sunlight. Sunglasses are usually labeled to indicate whether they block UVA or UVB rays or both. Choose sunglasses that block both UVA and UVB rays to give your eyes the most effective protection against us.

7. Sunscreen 

 Use a broad-spectrum SBF sunscreen before going out in the sun. Be sure to use a thick layer in all areas that may be exposed. Reapply sunscreen as needed throughout the day. Remember that you can be sunny on cloudy days!
