Why kids just DON'T get cold outside revealed trends now
Have you ever wondered why children don't seem to feel the cold outside?
Well, scientists say there is a reason why adults are often freezing while wearing a jumper and youngsters are happy in shorts — even in frosty conditions.
And it's not just down to them constantly jumping around.
Their secret? Having more brown fat — specialised fat cells designed to create heat and maintain the body's 37C (98.6F) internal temperature.
Unlike white fat, which is seen in abundance around midriffs, bottoms and chins, the brown type is invisibly and compactly distributed deep inside, especially around the shoulder blades, spine and kidneys.
It makes up close to 5 per cent of a newborn's body fat, but levels gradually decline with age — leaving adults more vulnerable to colder temperatures.
Brown fat gets its colour because it is packed with iron-rich mitochondria, the powerhouses of the cell. Unlike white fat, which is an energy reserve, brown fat uses its power in the mitochondria to burn energy of its own. When this fat burns it is able to create heat without shivering which is called thermogenesis. As shown in image above babies have more brown fat than adults
Aside to wrapping up warm in the winter, our bodies also have their own methods of keeping warm. Adults shiver and also brown fat helps to create heat. But young children have more brown fat than adults, which could be why they appear to be warm even in winter
Brown fat gets its colour because it is packed with mitochondria, the powerhouses of the cell that are abundant in iron.
Its counterpart, the white variety, acts as a reserve for the body's organs to burn for energy.
Yet when the body is exposed to the cold, from around 16C, brown fat gets activated — starting its engine to create heat in a scientific process called thermogenesis.
It does this by burning extra calories, breaking down blood sugar and fat molecules floating around the body.
And it is for this very reason, experts also think it could be a secret weapon to help beat the bulge.
Dr Dayn Sellayah, an expert in cellular and organismal metabolism based at Reading University, told MailOnline this ability is all because of a unique protein in brown fat.
Uncoupling protein 1, as it is scientifically known, allows brown fat to break down glucose and fat molecules to make
