Sunglasses with appropriate filters to protect us and help prevent, but they are of poor quality may worsen the harmful effects of ultraviolet (UV).
The sun does not always cause the same effects. In summer, for example, is more dangerous. The altitude may also influence because we have less atmosphere above us to protect us. If there’s snow, the risk increases by 90% because the reflected rays and radiation increases as the water or sand, to a lesser extent. It is also determining the time of day, being worse the central hours. And we must take into account that the clouds let through the ultraviolet rays, so that there is still risk. Finally it should be borne in mind that children are always particularly exposed to these risks.

Essential Nutrients
WATER
Essential component for life and abundant in most foods. Water is absorbed in the intestine and then transported by the blood to other organs. Can be found in the body as part of the intracellular cell protoplasm and extracellular, and interstitial fluid, lymph, and as part of blood plasma.
FUNCTIONS
- Transportation of nutrients and waste products
- Regulation of body temperature
- Solvent substances
- Structural component of cells
Water is excreted through urine, feces, skin and lungs. The balance between loss and gain of water should be neutral because a positive balance of ending a picture of water retention and a negative a picture of dehydration.
Triglycerides
Name and Type of Test
Triglycerides are fats, or more lipids, the body needs for the formation of structures essential for cells and therefore travel through the bloodstream. Considered a great reservoir of energy for our body. As with cholesterol, the liver is the main factory of triglycerides in our body. It is not often isolated elevation of triglycerides without alteration of other lipids such as cholesterol, but there are familial diseases and dietary changes that can condition an increase in their normal numbers will cause hypertriglyceridemia, with the consequent emergence of pathologies associated with its increase in blood.
Foot care in diabetics
In all the long-term complications that diabetes can cause, the effect on blood vessels (arteries) and peripheral nerves are the most common.
Involvement of the arteries causes the blood supply to certain organs evil arrives and extremities, causing undesirable effects, such as injuries to occur more easily, and delayed or poor healing of the same, if complicated by infection (also more common in diabetes), can reach the loss of fingers, the foot, and even the limb.
The nerve involvement results in decreased sensitivity, which in turn favors the occurrence of injuries with greater ease, not having the defense mechanism of pain, which will retire the end of the injurious element (eg. A source near heat).
They can also produce pain syndromes.
