Winter is here, and households everywhere cherish the comfort of warm heating. However, as reported by Time magazine's website on the 22nd, scientists have recently discovered that lower indoor temperatures may actually help people maintain a slimmer figure. Cold exposure not only aids in physical conditioning but also appears to offer significant benefits for diabetes management.
Researchers at Maastricht University Medical Center in the Netherlands conducted an experiment revealing that lower temperatures affect body weight.Fifty-one young men spent 10 days living in a cold chamber maintained at approximately 62°F (16.7°C). They eventually acclimated to the low temperatures, with a significant reduction in shivering episodes. This adaptation persisted even when the temperature was lowered to 60°F (15.6°C).Scientists discovered these physiological changes were attributable to the body's brown fat. Brown fat is primarily distributed between the shoulder blades, the back of the neck, the armpits, the mediastinum, and around the kidneys, earning its name from the darker color of its mitochondria.Infants and young children possess a higher proportion of brown fat, which gradually diminishes with age. Unlike white fat, which stores energy, brown fat functions to expend energy, thereby generating heat.
Researchers at the University of DuBrouwer Medical Center in Canada discovered that cold temperatures activate brown fat in the human body. Activated brown fat accelerates metabolism and promotes the breakdown of white fat. Additional studies indicate that for individuals under 60, brown fat can expend up to 30% of the body's energy to generate heat in response to cold, offering an alternative pathway for weight loss.
All these findings suggest that the heating devices we rely on during winter may actually hinder our efforts to maintain a healthy figure. Spending all day in warm rooms makes the body less adaptable to sudden temperature changes, increasing the global population's susceptibility to diseases like diabetes.
At this point, some might ask: If Inuit people live in cold environments year-round, shouldn't they be "very thin"?This contradicts the above argument. In reality, the physical characteristics of the Inuit are deeply influenced by their unique living environment. Their habitat is unsuitable for agriculture, so their staple diet consists largely of high-fat, high-protein meats. The fat in such foods is predominantly white fat, which accumulates under the skin and easily leads to obesity.
Scientists are actively exploring ways to harness the unique functions of brown fat for treating diabetes. Meanwhile, in our daily lives, we should practice self-control—avoid immediately cranking up the indoor temperature at the slightest chill. Even a slight reduction in temperature can significantly aid in maintaining a healthy physique.
