Neuroscience News: UV Light Increases Appetite But Suppresses Weight Gain

A recent study published in the Journal of Investigative Dermatology has found that exposure to ultraviolet (UV) light can increase appetite while preventing weight gain by affecting hormones and neurotransmitters. Researchers observed that UV exposure in mice led to decreased leptin levels and increased norepinephrine, promoting energy expenditure and preventing weight gain even with increased appetite. Future research will focus on developing safe methods to replicate the beneficial effects of UV exposure without its adverse impacts.

A Northwestern Medicine study, published in JAMA Dermatology, is the first large-scale research examining mental health issues in children with chronic skin conditions. The study found that many children and teens with conditions like acne, eczema, psoriasis, alopecia areata, and vitiligo experience significant stigma and bullying, leading to depression, anxiety, and poor peer relationships. The study, involving 1,671 children and 31 sites, revealed that 73% had experienced stigma, which was linked to a poor quality of life. Researchers also discovered a discrepancy between how children and doctors rated the severity and visibility of the disease.
