Exposure of skin to ultraviolet radiation from sunlight presents both positive and negative health effects. On the positive side, UV exposure enables the synthesis of vitamin D3, which is essential for bone health [1] and potentially plays a role in inhibiting certain cancers. [2][3] While vitamin D can also be obtained through dietary ...

Too much sunlight is harmful to your skin. A tan is a sign that the skin has been damaged. The damage is caused by ultraviolet (UV) rays in sunlight.
If work keeps you outdoors for a long time your skin could be exposed to more sun than is healthy for you. Outdoor workers that could be at risk include farm or construction workers, market gardeners, outdoor activity workers and some public service workers. If you have naturally brown or black skin, you are less at risk of skin cancer, although ca...
In the short term, even mild reddening of the skin from sun exposure is a sign of damage. Sunburn can blister the skin and make it peel. Longer term problems can arise. Too much sun speeds up ageing of the skin, making it leathery, mottled and wrinkled. The most serious effect is an increased chance of developing skin cancer.

Jul 16, 2024 · UV radiation can cause short- and long-term health effects on the skin. In addition to the well-known short-term effects such as sunburn or allergic reactions, long-term effects like skin cancer represent a chronic health risk. Skin cancer risk is strongly correlated with the duration and frequency of sun exposure over one’s lifetime.

- Introduction. Sunlight comprises infrared, visible and ultraviolet (UV) rays. This guidance focuses on the balance of risks and benefits from the UV rays, specifically the UVA and UVB rays that reach the earth's surface.
- Overexposure. Overexposure to sunlight can result from spending long periods in the sun on a habitual basis. This is known as chronic exposure and can occur, for example, among people who work outdoors.
- Vitamin D. Between October and March in the UK, sunlight contains very little of the ultraviolet B (UVB) wavelength the skin needs to make vitamin D. So people rely on body stores from sunlight exposure in the summer and dietary sources to maintain vitamin D levels (SACN update on vitamin D – 2007 The Scientific Advisory Committee on Nutrition).
- Skin cancer. Excessive exposure to UV rays is an important and avoidable cause of skin cancer. Skin cancer incidence rates (melanoma and non‑melanoma) have increased rapidly in England in the past 30 years.
Excessive sun exposure in children and adolescents contributes to skin cancer in later life. A certain amount of UV exposure is beneficial to health, in particular for vitamin D. Simple and effective prevention measures are available. Sun protection is recommended when the ultraviolet index is 3 and above.
Jul 31, 2023 · Myth #1: The sun is strongest when it’s hottest. Surprisingly not necessarily. UV rays from the sun cause the skin damage that can lead to cancer, but UV rays aren’t hot and you can’t feel them. The heat of the sun comes from a different type of ray, called infrared. UV rays are strongest when the sun is highest in the sky, which in the ...
