Theoretically, sun exposure is conducive to our health. Sun rays accelerate metabolism making our bodies produce more carbon dioxide. The increased level of CO2 in the lungs lessens our breathing and creates a strong positive impact on all functions of the body.
On a practical level, however, this situation can be different. The prolonged sun exposure causes overheating, which stimulates over-breathing. Hyperventilation is dangerous: it hits the weakest organ or system of the body triggering various symptoms.
So, how do you determine the borderline between sun exposure being safe and detrimental? Usually, a body indicates this by making its skin red or creating a rash but these valuable messages get removed by the usage of sunblocks.
The human body is very intelligent. Unfortunately, its language is frequently shot down in favor of comfort but by doing so we never win.
