Overview
Could exposure to the right kind of light aid in weight loss? Researchers at Northwestern University suggest so, backed by studies indicating a significant impact of light on body weight. The artificial light environment indoors, especially when received at the wrong times, can disrupt the body's circadian rhythm, affecting blood sugar levels and calorie utilization.
The length and intensity of exposure to bright light, along with the timing of exposure, are linked to weight fluctuations, as per the Northwestern investigation. Individuals exposed to bright light in the morning exhibited lower body mass indexes compared to those exposed later in the day. This relationship remained consistent even when considering factors like caloric intake, sleep patterns, age, and season.
Light plays a crucial role in regulating the body's circadian rhythm, which influences metabolism and energy distribution. Getting sufficient bright light between 8 a.m. and noon can help lower body mass indexes. However, many individuals lack exposure to natural light due to spending prolonged periods indoors.
Avoiding bright light at night is advised to maintain healthy blood sugar levels and prevent insulin resistance. Dimming lights in the evening and seeking natural light in the morning can contribute to weight management and improved health outcomes.
