Sun exposure can make you live longer!

We are used to be warned about sun exposure, we know all of its risks and we know that we shouldn’t look at the sun [1] neither stay too long because of sunburn [2] and skin cancer [3]. But what about its benefits?

Usually we don’t see a lot of information on this concern, but nowadays this topic is starting to have more visibility. As the ancient greek proverb states, “virtus in media stat “(virtue stands in the middle). This is what in fact happens with sun exposure.

The benefits include the reduction of hypertension and cardiovascular disease. As a side note, cardiovascular disease is the number one cause of death, accounting 30% of deaths worldwide. [4] Dr. Richard Weller studies have successfully showed that UVA (Ultraviolet radiation A) activates NO(Nitric Oxide) that is stored in the skin which dilates blood vessels hence making an important change in hypertension and cardiovascular disease. [5]

The following video might facilitate the comprehension of this difficult subject.

 

Other benefit now caused by other component UVB (Ultraviolet radiation B) is that it seems to protect from MS (Multiple Sclerosis) according to recent studies there is a strong evidence for this. [6] This happens due to the Vitamin D that is created on our body by UVB. [7]

The last benefit I will present is about SAD (Seasonal Affective Disorder). This is a mood change that occurs in summer or winter. As in other animals winter brings an extremely hard survival environment and so animals tend to diminish activity. This is probably what also happens in humans setting a cosy atmosphere for humans sleep and feeling depressive. So revealing this is really a fact sun exposure is able to trigger a good mood. [8]

Conclusion, in spite of the fact that sunlight seems to attack you that is not actually the true there’s this “other side of the coin” which matters for your life span.

This is a lengthier post that I will make all possibles to not repeat. This gave me a lot of work (selection of information and selection of fonts) so I hope you like it. Give some feedback and see you next time! Quality before quantity!
