How UV affects us

Looking west Isle of Wight, Taken on a local walk a few weeks ago.

I found this an internet explanation. Thanks to Striated Cacara.

UV rays damage the cells of the skin. When the cells of the skin become damaged from UV light, it causes them to die, in a process known as apoptosis. In a person without lupus, the body quickly clears the dead skin cells. Additionally, any sunburn or irritation heals within a short time.

A person with lupus may also have skin cells that are more sensitive to sun-induced damage. Their body may not be able to clear the dead skin cells away effectively. They may form immune complexes that stay in the body for longer, further triggering an immune response and leading to a lupus flare.

Thanks for posting.👆👏

Yes as lupus sufferers we all have to be extra careful outdoors but perhaps our photosensitivity is giving us a warning? 🧐

UV is invisible!👆

A most important topic for ALL seasons!

I Googled the term “mechanisms of uv damage” opting for images and you get a huge number of fascinating explanatory diagrams showing how cellular DNA damage occurs firstly and then how skin cancer develops! Understanding the science helps us all.

Try it!

Thanks Suvi for posting. Excellent science.

Note that the much hyped and ignorantly Hollywood celebrity/media endorsed bronze or tanned look amongst white people is a sign of SKIN ageing, damage and perhaps permanent wrinkling?😱👆

Sad indeed. Poor sun lovers and sun bathers🙄☹️

Us lupus sufferers know or should know better?😳
