sun affects our body

People enjoy the sun. Some have even worshiped it. Sunlight is essential to many living things. You know that the sun's ultraviolet (UV) rays can cause skin cancer and premature aging, and that wearing sunscreen is an important way to protect yourself. But research has shown that sunlight also seems to affect health in a lot of other ways, both positively and negatively.

negative point-

One American dies every hour from skin cancer, and the overwhelming majority of these cancers are caused by overexposure to UV light.Years of unprotected sun exposure can lead to permanently red, blotchy skin,the same UV rays that can cause harm to your skin can also damage your eyes, increasing the risk of developing cataracts or other vision problems. In serious cases, this can lead to complete blindness, the study says.

positive points-

Sunlight also helps our skin make vitamin D, which is needed for normal bone function and health. Many studies have suggested that Vitamin D deficiency is linked to cardiovascular disease. That may be because vitamin D helps the body absorb calcium, which is important for healthy bones . Sunlight triggers the release of the feel-good brain chemicals serotonin, so spending time outdoors has been shown to boost mood and relieve stress.Sunlight exposure impacts how much melatonin your brain produces and melatonin is what tells your brain when it is time to sleep. When it gets dark, you start producing melatonin so you are ready to sleep in about two hours. With more sunlight in the summer, you are likely to feel more awake.

Women who reported spending an hour or more outside every day for the last 10 years were less likely to have had breast cancer than those who reported less time in the sun.Limit time in the sun to protect your skin against early wrinkles, damage, and disease.Children who live in low-sunlight areas are more likely to be allergic to eggs and peanuts than those who get plenty of rays, according to a 2012 Australian study.

vitamin D levels play a role in the body’s immune response, so enjoy sunlight with protection like use sun glasses and use sun screen lotion or used wide-brimmed hats, or long-sleeve shirts.
