Blue Light May be Key to Fighting Winter Blues

Lack of sunlight during winter can lead to the condition known as seasonal affective disorder (SAD). This can make you feel lethargic, gloomy, and irritable. However, while daylight as a whole is beneficial to fight off the syndrome, different colors of light seem to affect your body in different ways.

Blue light can affect your mind, including mood. And according to a new study, blue light might play a key role in your brain's ability to process emotions. The study results suggest that spending more time in blue-enriched light could help prevent SAD.

CNN reports:

“Studies have shown that blue light improves alertness and mental performance ... [T]he researchers discovered that blue light, more so than the green light, seemed to stimulate and strengthen connections between areas of the brain involved in processing emotion and language.”
