Importance of Sunlight for health (100 words )
Answers
Sunlight and darkness trigger the release of hormones in your brain. Exposure to sunlight is thought to increase the brain’s release of a hormone called serotonin. Serotonin is associated with boosting mood and helping a person feel calm and focused. At night, darker lighting triggers the brain to make another hormone called melatonin. This hormone is responsible for helping you sleep.
Without enough sun exposure, your serotonin levels can dip. Low levels of serotonin are associated with a higher risk of major depression with seasonal pattern (formerly known as seasonal affective disorder or SAD). This is a form of depression triggered by the changing seasons.
A mood boost isn’t the only reason to get increased amounts of sunlight. There are several health benefits associated with catching moderate amounts of rays.
Sunlight and mental health
Decreased sun exposure has been associated with a drop in your serotonin levels, which can lead to major depression with seasonal pattern. The light-induced effects of serotonin are triggered by sunlight that goes in through the eye. Sunlight cues special areas in the retina, which triggers the release of serotonin. So, you’re more likely to experience this type of depression in the winter time, when the days are shorter.
Explanation:
The sun's UV rays help your body make this nutrient, which is important for your bones, blood cells, and immune system. It also helps you take in and use certain minerals, like calcium and phosphorus.
The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a principal source of vitamin D₃ and a mutagen. A dietary supplement can supply vitamin D without this mutagenic effect.
