Often touted as the best color for sleep, blue is reminiscent of the sky and sea, possibly evoking a sense of calm and serenity. Some surveys suggest that people sleeping in blue rooms tend to enjoy longer, more restful sleep.
Prolonged exposure to blue wavelength light has been shown to have an alerting effect, and enhances performance on cognitive tasks. A small number of studies have also shown that relatively short exposure to blue light leads to changes in functional brain responses during the period of exposure.
Also, some research has found that blue light therapy may contribute to aging by causing free radical damage to the skin.
Scientists think nighttime exposure to blue light throws off your circadian rhythm, or sleep/wake cycle. This could lead to symptoms of depression. That's because your circadian rhythm plays a role in several brain and behavioral processes, like neurotransmission and hormone secretion.
STAY INSIDE and keep the treated areas not only away from sunlight but also any bright lights for 96 hours. Exposing the treated areas to direct and indirect light within this time period can lead to a severe blistering reaction in the areas that were treated.
A 2017 study reported in the scientific journal PLOS ONE (3) found that blue lighting leads to post-stress relaxation three times as quickly as conventional white lighting. Blue light's potential calming effects have been observed outside scientific studies as well.
How do I choose the right bed colour for my room? Consider both your personal preferences and the existing colours in your room. Think about the mood you want to create. For calmness, go for blues; for warmth, consider pinks or reds.

The best night light colors for sleep are red and amber, as they are warm and soothing colors that promote a good night's sleep. It's thought that colors close to red on the light spectrum stimulate melatonin production.
What is blue light therapy really good for? It's most effective against mild to moderate acne. Professional-grade devices like the CurrentBody Skin Anti-Acne LED Face Mask are also effective for a larger range of concerns including fine lines and wrinkles, hyperpigmentation, redness, psoriasis and muscle or joint pain.
Light from electronic screens comes in all colors, but the blues are the worst. Blue light fools the brain into thinking it's daytime. When that happens, the body stops releasing a sleep hormone called melatonin. Melatonin is nature's way of helping us wind down and prepare for bed.
Blue light therapy may help some people with depression regulate certain symptoms. This therapy seems most effective in people with seasonal depressive disorder. However, other forms of depression may also benefit from it. Research has been generally positive.
Warm hues of red, orange, and yellow are better for preparing the mind and body for sleep. In fact, some experts recommend switching to warm lights.

Blue light itself cannot whiten the teeth. Instead, blue light is used to activate a chemical reaction. You'll apply a specialized whitening gel to the patient's teeth containing either carbamide peroxide or hydrogen peroxide. The blue light activates the compounds in the gel and helps break it apart faster.
On short term, blue light stimulates dopamine production, but long-term light exposure has the opposite effect and leads to symptoms such as anxiety, mood swings, inability to focus, lack of insight or self-awareness, low libido.

“Our previous work demonstrated that daily lifelong exposure to blue light, but not other visible wavelengths, has damaging effects on the brain, motor abilities and lifespan of the model organism,” Giebultowicz said.
