Skin exposure to the sun promotes synthesis of vitamin D, therefore getting some sunshine seemes tpbe a good thing for HBVers however spme studies suggest that UV suppresses immune system impairing T-cell function and can lead to relapse of some virus infections

"Several studies have demonstrated that exposure to environmental levels of UV radiation alters the activity and distribution of some of the cells responsible for triggering immune responses in humans. Consequently, sun exposure may enhance the risk of infection with viral, bacterial, parasitic or fungal infections, which has been demonstrated in a variety of animal models".
Any thoughts on this subject?
