We can’t wind back the clock to the early 19th century when most people spent their days working outside and their nights in darkness illuminated only by few candles.
But today, in this modern world, at least 90 percent of Westerners spend their life indoors as we are too much relied on technology and this is also changing our relationship with light.
Exposure to sunlight triggers production of the “happy hormone,” or serotonin. Medical research links serotonin balance to feelings of contentment and we’ll-being. Low light or darkness triggers melatonin production. It is a hormone responsible for making you sleepy.
Not getting enough sunlight means lesser level of serotonin in our body which can result in bad mood, tiredness and can also lead to depression.
The best-known benefit of sunlight is its ability to boost the body’s Vitamin D supply. Getting too little sunlight will contribute to vitamin D deficiency which will lead to bad immune and cardiovascular system.
Low levels of vitamin D can cause heart disease, prostate cancer and dementia. Our body is meant to be in sun, and exposure to sunlight during the day is crucial to our well being. It is advised to get at least 10-15,minutes of sunlight daily.
