We all know that the Sun is the main factor responsible for life on Earth. But did you know that it is also responsible for happiness? What happens here is that, as many people already know, the Sun is capable of stimulating the production of vitamin D in the human body.
But few people know that it is through this vitamin that serotonin hormones, also known as the happiness hormone, are produced.
Serotonin is the hormone that gives us a feeling of rest, happiness and pleasure, and therefore it is the hormone that lifts our mood. However, even though many people know this, especially scientists, there was no information about how much the sun could stimulate this production.
Therefore, Gavin Lambert, along with other scientists, conducted research in Australia, with the aim of understanding how much the Sun affects our system. To do this, the scientists found a group of 101 male volunteers for the research.
Research results on solar influence
The research was carried out using blood samples from 101 volunteers. One part was taken on cloudy days, while the other was taken on sunny days. Through this, and a comparison made between samples from different seasons, the scientists reached their conclusions.
The difference in serotonin levels on sunny days compared to cloudy days was about eight times greater. In other words, men who were tested on bright days had much higher serotonin production than those who were tested on days with less light.
Therefore, it is no surprise to anyone that, in the summer, hormone production was much higher than in the winter, when there is less sunlight.
However, it is interesting to note that, even though production is high, the effect of sunlight does not last until the next day. Therefore, its higher production effect only works during contact with sunlight.
According to the study, therefore, the body’s contact with sunlight for half an hour is capable of producing around 10 to 20 thousand units of vitamin D, which, in turn, will influence the production of serotonin.
In other words, it is not necessary to spend the whole day under the sun, just take some time out of your day to do some outdoor activity and you will have already produced enough to improve your mood.
