Swap Your Fridge Bulbs

The lights could affect your diet.

Every athlete knows that education is a crucial part of performance. Sport and exercise research, insight from top trainers, science, and technology help you to better understand your body so you can craft a healthier lifestyle, workouts, and recovery plan.

In our daily news series, experts address some of the latest fitness research, nutrition, style, and health stories.


THE GIST
Many experts believe the color blue helps suppress appetite, possibly because it’s rarely seen in nature. One study found that people who had breakfast in a room filled with blue-spectrum light consumed less food than those who ate in a room lit with white or yellow bulbs.
EXPERT INSIGHT
Blue light is notorious for messing with your sleep, and research shows that staring at your phone or laptop at night can actually increase your appetite. 

But if you use it strategically, it could help you make healthier food choices. Replacing your current fridge bulbs with LED or fluorescent ones (which produce more blue light) could subconsciously guide your eating habits, and the exposure would be brief enough to not affect your circadian rhythm, says Matt Berenc, CSCS, Beverly Hills-based director of the Equinox Fitness Training Institute.
THE BOTTOM LINE

More research is needed to determine the long-term relationship between blue light and appetite, so don’t swap all the bulbs in your home. In the meantime, filling your fridge with it—or even eating off of blue plates, Berenc says—can help you stick to your nutrition goals.
