The researchers from Rutgers determined that the flower recipients in the study experienced an elevation in mood that lasted for days. Each color creates a different frequency of lightwaves, they believe, which travel through the retina and down the optic nerve, setting off a chain reaction of responses in the body. Neurotransmitters are then released, inducing the production of calming hormones like melotonin, stimulating hormones like adrenaline, and mood-boosting hormones like serotonin. Since red has the slowest vibratory rate and and longest wavelength, it stimulates adrenal glands, boosting energy. Boost confidence with irises The color indigo stimulates the brain's pineal gland, which is the regulator of sleep patterns.

Enhance alertness with sunflowers Yellow lightwaves stimulate the brain, making you alert, clearheaded and decisive. And since we associate yellow with the sun's rays and daylight, it's said to help us feel more optimistic. Blue triggers the production of melotonin, a brain chemical that helps us relax and sleep soundly. Blue also stimulates the thyroid gland to release thyroxin, a hormone that regulates metabolic rate. Green affects the nervous system, making us breathe slowly and deeply, slowing the production of stress hormones and helping the heart relax.
