A recent study identifies the fundamental issue that increases men’s hunger in the summer.
According to a recent study, sunlight not only makes us hot and sticky but also increases our hunger as the world struggles to cope with the effects of extreme weather events, particularly heatwaves. Researchers have discovered that in men, sunshine causes a special hormone that increases appetite.
Researchers from Tel Aviv University’s Sackler Faculty of Medicine examined environmental cues, such as exposure to solar ultraviolet (UV) radiation, that result in certain modifications. They discovered that exposure to sunlight may have more subtle impacts than previously thought on the physiology of men.
According to a study that was published in the journal Nature Metabolism, “Solar exposure induces food-seeking behaviour and consumption in men but not in women.” The group argued that sex disparities had a significant impact on behaviour and health1. However, little research has been done to determine whether men and women respond to environmental cues like ultraviolet (UV) light differently.
According to studies done on mice, exposure to ultraviolet light increases appetite, calorie intake, and weight gain with a sexual preference for males. According to the study, elevated levels of circulating ghrelin are associated with increased appetite in both male mice and humans.
In a three-year analysis of data from 3,000 individuals in a national nutrition survey, researchers discovered that only men increased their calorie intake by 300 per day over the summer. Despite the small amount consumed, weight gain may result if it is continually consumed over time.
The ghrelin release, which most likely occurred as a result of DNA damage in skin cells from excessive sun exposure, was what caused the want to eat more. Oestrogen most likely prevented this in women. Researchers argued that ghrelin and leptin8 hormones are involved in the intricate process of hunger regulation, which has a direct impact on health. Following a meal, ghrelin levels are at their lowest and then rise.
Music, light, and odour are examples of environmental cues that affect ghrelin secretion, although the underlying mechanisms are yet unknown. Researchers wrote in the publication that their findings “identify the skin as a critical modulator of energy homeostasis and may lead to therapeutic prospects for sex-based therapies of endocrine-related disorders.”
