Sun and Skin - Part 3: Immune Response
The Immune Response
As the body’s largest organ, our skin is an integral part of our immune system; when skin is damaged our immune system is weakened. Skin is our primary line of defense and provides a barrier against many external threats, but radiation is not one of them. Ultraviolent radiation damages skin and compromises immune response, leaving us vulnerable to illness and infection.
We have know for sometime that UVB radiation impacted immune responses including contact hypersensitivity (CHS) and delayed-type hypersensitivity response (DTH), and now more recent studies have demonstrated that UVA is also significantly involved in immunosuppression. Preventing UV induced immumosuppression requires us to protect ourselves from the entire UV spectrum.”
