Sun And Air Benefits For Health
A white skin is more prone to become redden, swell, generate blisters, develop tumors, etc. When the skin is well pigmented, these risks gradually disappear.
When the skin receives more solar radiation than which is ready for absorb, suffer a more or less intense hyperemia, ie a redness by more increased blood flow.
If this redness is mild, poses no danger. The surface hyperemia decongest internal organs, as we shall see when we discuss hydrotherapy.
But when the redness is excessive, can get to appear erythema, the sunburn. We must avoid at all costs. We must ensure that the skin suffers only a slight redness, which will produce a gradual and healthy pigmentation.
Excessive redness will produce a quick but not lasting pigmentation, as is often accompanied by flaking in a few days . If we abuse even more, it can produce various types of used solar accidents: dermatitis, rashes, blisters, etc, that might get to degenerate into malignant formations.
The sun, like any therapy, it is good in its proper dosage, beyond which it becomes pernicious, being able to reach even death from insolation.
Concerning the infrared spectrum of sunlight radiation we can be noted that the heat generated by said rays rapidly produces a slight hyperemia in the skin, by peripheral vasodilation, that which clears the internal organs.
As a result, we noticed a slight relaxation and sleep, caused by a slight temporary cerebral anemia, ie, decreased blood flow in the brain. Thus, these rays are slightly analgesics and sedatives.
Also produce a great general blood circulation, and fever-like state:
temperature increase, increase brain activity, heart and lung, sweating activation, etc. Thus, we can see how increases the metabolism, thus producing greater oxygenation and elimination of toxins
