![]() While this essential vitamin doesn’t come directly from sunlight, it does help transform chemicals already in your skin, according to Harvard Health Publishing. ![]() Sunlight helps your body produce vitamin D. Here’s how the sun helps you produce one of the 13 essential vitamins, as well as several other important benefits it provides. Interfering with this UV-induced vitamin A deficiency is a new concept for the prevention of skin cancer and aging.It’s common knowledge that plants require sunlight for photosynthesis, a biological process which is essential to their growth - but did you know the sun also provides significant health benefits to humans?ĭespite numerous risks associated with prolonged exposure to the sun’s powerful ultraviolet rays (sunburn, skin damage, skin cancer and more, according to the Mayo Clinic), the sun is actually vital to a number of the human body’s functions. The physiological role of this adaptive response to acute and chronic sun exposure should be further analysed. ![]() Current data indicate that the vitamin A system is a direct target of both UVB and UVA and participates in an adaptive response to UV exposure. We have conducted a series of experiments in order to analyse the effects of UV exposure on the epidermal stores of endogenous vitamin A (retinol and retinyl esters), the activity of enzymes and binding proteins, and some biological parameters such as apoptosis transcription factors expression (cJun) and thymine dimers. ![]() This complex system may be drastically altered upon ultraviolet light exposure because vitamin A absorbs in the UVB range. Human epidermis contains significant amounts of Vitamin A, the enzymes responsible for its metabolism toward either storage or activation, the binding proteins for its protection and specific transport, and the nuclear receptors involved in the vitamin A-induced gene-activity modulation. ![]()
