Stimulating the formation of hemoglobin, preventing and combating rickets, preventing skin diseases (psoriasis), the beneficial influence on the nervous system, increasing resistance to infections, and stimulating the production of vitamin D, are just some of the benefits of moderate sun exposure.
But if sun exposure is made in an irrational way, it may also have negative consequences: immediate consequences, such as erythema and sunburn, or late, such as skin diseases or skin cancers.
Through the process of tanning, the skin actually tends to fend off the rays of the sun. Under the stimulation of radiation, the melanocytes release melanin, a protein substance able to absorb UV rays and block their action before they cause damage to skin layers. Melanin is synthesized from tyrosine under the influence of an enzyme called tyrosinase. The main role of melanin is to absorb UV radiation and protect us from the effects that can be extremely unpleasant (sunburns and premature aging, triggering skin cancer, etc.). But melanin alone can not provide full protection so that it is absolutely necessary to protect our skin by using cosmetics to act as a solar filter and to feed and care for the skin after sun exposure.
To prevent sunburns you have several options: you can apply protective creams with high SPF, nourish the skin after exposure to sunlight with a moisturizer and you can avoid sun exposure during peak hours between 11 and 15. And to restore water balance of the body consume at least 2 liters of fluid a day to replace the water your body loses from perspiration.
