Recent study from Icahn school of medicine at Mount Sinai explained how the body regulates it’s production of heat.
Researchers had hypothesized that macrophages is responsible for keeping the body warm, the recent study suggests sympathetic nervous system.
Christoph Buettner, a professor of medicine led the research team. They focused on catecholamines, hormones released by the sympathetic nervous system to activate brown fat tissue.
Brown adipose is a fat tissue that burns energy and produce heat and keep us warm.
Dr Buettner suggested that one of the ways of controlling effects of diabetes and obesity is to regulate the production of heat and metabolism by the brain and the nervous system.
