"For example, we dont yet know the intensity and duration of light necessary for this pathway to be activated."The researchers made the discovery while investigating how to bioengineer fat cells to produce insulin in response to light to help Type 1 diabetes patients."When the suns blue light wavelengths--the light we can see with our eye--penetrate our skin and reach the fat cells just beneath, lipid droplets reduce in size and are released out of the cell. "Maybe this mechanism contributes to setting the number of fat cells we produce in childhood -- thought to stay with us into adulthood," he speculated. "We noticed the reaction in human tissue cells in our negative control experiments, and since there was nothing in the literature, we knew it was important to investigate further. You gain weight in the winter, and then burn it off in the summer. In other words, our cells dont store as much fat," said Peter Light, senior author of the study. The study has shown the fat cells that lie just beneath our skin shrink when exposed to the blue light emitted by the sun.Washington: Heres another reason to bask in the sunshine!According to a recent research, fat cells are sensitive to sunlight and therefore, reduced sunshine in winter may contribute to weight gain. "If you flip our findings around, the insufficient sunlight exposure we get eight months of the year living in a northern climate may be promoting fat storage and contribute to the typical weight gain some of us have over winter," he added."Based China IP65 lights Manufacturers on the finding, the fat cells we store near our skin may be a peripheral biological clock, said Light."This could be evolutionary process, supported by the fact that unlike many other mammals, our fat is spread out all over our bodies just underneath our skin, he added. "Obviously, there is a lot of literature out there suggesting our current generation will be more overweight than their parents and maybe this feeds into the debate about what is healthy sunshine exposure.The study has been published in the journal Scientific Reports.. "
It was serendipitous," said Light."He explained that the molecular pathway they discovered was first identified as being activated by the eye when exposed to the blue wavelengths in sunlight."However, he added the novel discovery opens up new avenues of future scientific exploration which could someday lead to pharmacological or light-based treatments for obesity and other related health issues such as diabetes.Light cautions the finding is only an initial observation and that pursuing exposure to sunlight is not a safe or recommended way to lose weight. "Its early days, but its not a giant leap to suppose that the light that regulates our circadian rhythm, received through our eyes, may also have the same impact through the fat cells near our skin. "Well, perhaps that pathway -- exposure to sunlight that directs our sleep-wake patterns-- may also act in a sensory manner, setting the amount of fat humans burn depending on the season. "Thats why you are not supposed to look at digital devices before bed because they emit the same blue light the sun does, that signals us to wake up," he explained.
