Sunlight may play an important role in weight management

There are many in hibernating animals and infants of humansBrown adipose tissue(BAT: brown fat)Is an adipose tissue that generates heat and consumes energy, but we already know that BAT activity declines in adults, especially obese people. It is attracting attention in the field of weight loss therapy as it can prevent obesity if stimulating BAT and encouraging its work can prevent obesity.

It became clear that sunlight is heavily involved in the activity of BAT.

University of NottinghamProfessor Michael Symonds, specializing in developmental physiology at the medical department, has proved for the first time that Nikko plays a major role in controlling the activities of BAT.

"Our research suggests the existence of an unknown mechanism to control BAT activity in humans, which may lead to new therapies for obesity prevention and weight loss," Professor Symonds .

Traditionally in winter, the energy consumption increased due to the increased heat demand of the body. However, in recent years due to widespread use of heating and global warming, it is no longer necessary to warm your body by the activities of BAT. BAT seems to have 300 times the maximum calorific value per volume, compared with any other organization.

American Diabetes AssociationDiabetes magazineIn this study published in the present study, we checked the correlation between monthly temperature and solar radiation change by recording the presence of BAT in the body, targeting more than 3,500 patients. As a result, BAT was more abundant in women than men, and it became clear that the change in activity of BAT is strongly related to sunlight rather than temperature.

Activities of BAT are characterized by being active when it is cold and generating a large amount of heat, but the factors determining the amount of BAT in the human body are not yet clear.

"Our study showed that BAT fluctuates greatly according to the season.The study focused on the influence of sunlight and temperature because the two are the main factors that affect BAT's work in small mammals. The outcome of the research may be a clue to find a new way to promote BAT activity, especially in winter, "Professor Symonds says.

Since it is BAT which becomes active actively in winter to keep body temperature essentially, if it is withdrawn in a cold room as much as possible and it does not hit the sun, activities are promoted and will it lead to obesity prevention? Although exercising under the sun is more healthy, it may be that in the future a method to stimulate BAT may be developed pharmacologically.
