Sun exposure has both positive and negative effects on the human body. Here are some of the positive and negative effects of sun exposure:
Positive effects:
- Vitamin D production: Sun exposure helps the body make vitamin D naturally, which is essential for strong and healthy bones.
- Boosts mood: Sunlight triggers the brain to release the hormone serotonin, which can boost mood and promote feelings of calm.
- Better sleep: Sunlight helps set the bodys internal clock, and early morning sunlight in particular seems to help people get to sleep at night.
- Lower blood pressure: Research shows that sunshine can lower blood pressure and improve heart health.
Negative effects:
- Skin damage: Too much sun exposure can cause skin damage, including sunburn, premature skin aging, and skin cancer.
- Eye damage: Sun exposure can cause damage to the eyes, including cataracts.
- Immune system damage: Unprotected exposure to the suns ultraviolet (UV) rays can cause damage to the immune system.
Its important to note that the amount of sun exposure that is good for you depends on your skin tone, age, health history, diet, and where you live. In general, scientists think that 5 to 15 minutes of sun exposure, up to 30 minutes if you have dark skin, is about right to get the most out of it without causing any health problems. If you plan to stay out longer, its important to use sunscreen to protect your skin.
