Following the natural day and light pattern can help you combat obesity. This is common knowledge that being exposed to bright lights at night has its own set of ill effects on our body. Unnatural sources of light at night causes our natural biological clock to go haywire, affecting overall health, and there is growing evidence that obesity can be one of them. Read on to find out how.
In the modern times when the work hours extend well beyond the sunset, the circadian rhythm of our body is disrupted. Melatonin is a hormone which effects metabolism, but it is produced in our bodies only when it’s dark. Keeping the lights on prevent production of melatonin, throwing metabolism of our body in a disarray and causing weight gain.
Our bodies function around the natural day and night cycle. Using artificial lights tricks our bodies to believe that it’s still day time and production of melatonin is inhibited.A recent study done by scientists in Israel shows that artificial light at night contributes to excessive weight in humans. The researchers believe that this is due to an evolutionary mechanism, which helped our ancestors stay warm through cold nights. BAT or Brown Adipose Tissue is a type of fat in our body which is primarily linked to generation of body heat by burning calories. Shorter days are an indication of winters and hence BAT activation is increased to help body stay warm in cold nights. During longer days, the body is conditioned to store fat for colder months of the yearSo, the length of the day essentially affects the storage of fat in our bodies.
Melatonin also helps control sleep and wake cycles in our body. When the hormone production is hampered due to artificial lights, it may lead to sleeplessness and stress which in turn cause an increase in weight.
In today’s world it is difficult to follow the natural day and night cycle, however you can still follow some steps to limit the effect of artificial lights on your body.
