Dr. Elisabetta Bernardi underlines the beneficial role of water in protecting the skin during periods of greatest exposure
MILAN – The long-awaited summer has now arrived and with it the heat, the sun and, above all, the first holidays. The Italians, lovers par excellence of this season, have begun the search for the perfect tan. Sunbathing not only helps our skin to become more and more golden but also supports the body in the production of vitamin D, thus favoring the development of the immune defenses. However, it is important to remember that exposing yourself to sunlight for too long or in the hottest hours, especially in this time of year when their action is most intense, can be very dangerous for the health of the skin. It is always good to adopt a series of behaviors that help avoid sunburn and irritation, including drinking more water.
When the skin is exposed to sunlight, melanin is activated inside the tissues, which, by coloring the outermost layer of the skin, creates a natural shield against the rays in order to protect it. But for a more effective defense, the action of melanin is not enough. To favor this mechanism, it is crucial to use protective anti-burn creams and a greater supply of water in order to hydrate the skin by increasing the formation of protective barriers. According to Dr. Elisabetta Bernardi, Biologist specialist in Food Science and member of the Sanpellegrino Observatory: “Getting more fluids during the summer months is essential if you want to prevent tissue dehydration. In this way, the skin regenerates itself more easily, stimulating the body’s protection system against the sun’s rays ”.
Exposure to the sun causes, in fact, a greater consumption of liquids, sometimes causing annoying burns, especially if the exposure time is prolonged and you are not protected enough with sun creams. “The stratum corneum – ie the outermost, and therefore exposed, layer of the skin, which has the task of protecting it – gradually loses its ability to retain water inside the body. This leads to greater dryness and less elasticity of the skin due to dehydration of the tissues, which facilitates sunburn. Again, hydration can be an ally in the burn healing process. A higher water intake helps to significantly reduce symptoms and promote faster healing, restoring the original elasticity and hydration levels “, continues the Doctor.
When sunbathing, it is therefore important to independently provide constant hydration but also to listen to your body and the signals it sends us when we do not take enough water, such as dizziness, feeling of thirst, dry mouth, fatigue and irregularity intestinal, which indicate a lack of fluids in the body. In this way, it will not only be easier to resist the peaks of heat that characterize our area in summer, but also to protect the skin from the strongest sun rays, while ensuring a perfect golden color.
