The color of your clothing may also be tiring you out. Dark colors like
black, navy and brown stimulate the secretion of melatonin--the chemical
that makes you sleepy. The good news is that studies show there are
many colors to keep you energized. White clothes suppress sleep-inducing
melatonin and boost serotonin--the feel-good chemical in your brain.
Red is good for an aggressive kind of energy. It's also been shown to
increase blood flow and stimulate adrenal glands. Yellow has been proven
to stimulate the brain, build self-confidence, and encourage optimism.
