Postmenopausal sun exposure may be harmful
At doctor visits, women are often asked to list their dietary supplements and medications. But what about the time they spend soaking up vitamin D?
A new study has found that high exposure to UV-radiation is associated with an adverse hormone balance in postmenopausal women.
UV-radiation affects the body through pathways that can have both positive and negative health effects, such as immunoregulation and vitamin D production. Different vitamin D metabolites are associated with higher or lower concentrations of estrogens and have the potential to alter the female sex hormone balance.
"When a woman reaches menopause, we see the levels of estrogens decline and an increase of other hormones, called gonadotropins,"​ explained Kai Triebner, researcher at the University of Bergen.
