16 Ιουλ 2024 · The only beneficial effect of UV, triggered by UV-B, is the stimulation of the production of vitamin D. Vitamin D has an important function in increasing calcium and phosphorus absorption from food and plays a crucial role in skeletal development, immune function, and blood cell formation.
Here we review the epidemiology of childhood actinic skin damage and conclude with evidence mostly from migrant studies of the role of childhood UV exposure in the development of adult skin cancers, in particular melanoma.
UV energy triggers skin-protective responses against stress, coordinated by the cutaneous-neuroendocrine system, and activates central neuroendocrine system pathways that regulate global homeostasis. The sensory and computing capabilities of the skin are designed to control cutaneous and body homeostasis (1).
Ultraviolet radiation (UVR) forms part of the electromagnetic spectrum — the energy emitted from the sun. UVR is categorised according to wavelength, which ranges from 100–400 nm. UVR is involved in tanning, accelerated skin ageing, ocular damage, and the development of skin cancer.
20 Οκτ 2024 · Light helps explains the evolution of our skin colour, why some of us have curly hair, and the size of our eyes. And light still shapes us today.

To date, there are tactics to protect the skin by preventing UV radiation and reducing the amount of UV radiation to the skin.
3 Ιαν 2020 · Ultraviolet (UV) light is invisible to the human eye and causes most tanning and skin damage. Scientists have shown that when UV light is absorbed by our skin, there is damage to our cells and our DNA, which can lead to skin cancer and other harmful outcomes; in general, the more UV light exposure, the higher the risk.
