Effects Of Blue Light On The Brain

Blue light exposure may increase the risk of macular degeneration.

Effects of blue light on the brain. Effects of blue light and sleep. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6 5 hours of exposure to blue light to exposure to green light of comparable brightness. Blue light exposure at night from smartphones tvs ipads tablets and computers and lack of sunlight and full spectrum light during the day is a major risk factor for insulin resistance anxiety depression mood disorders headaches and other health problems. It has long been known that light exerts powerful effects on the brain and on our well being.

The fact that blue light penetrates all the way to the retina the inner lining of the back of the eye is important because laboratory studies have shown that too much exposure to blue light can damage light sensitive cells in the retina. Blue light and the circadian rhythm. Blue light and our eyes. As light rays hit those cells they tell the brain to stop pumping.

Specialized cells in the retina are finely tuned to respond to the short wavelength light that comes from a cloudless blue sky. Recent research by the group has found a small effect of coloured light on heart rate and blood pressure. Exposure to blue light is detected by the eyes and signals the pineal gland to suppress the secretion of the hormone. Among the visible light spectrum blue wavelengths have the most powerful effect on your sleep wake internal body clock.

Both natural and artificial blue light can boost your alertness and mental. Human eyes have receptors that contain a photopigment called melanopsin that is sensitive to blue light. Red light does seem to raise heart rate while blue light lowers it. Before the technological age blue light primarily came from sunlight.

The visible light with the highest intensity is blue light and just above it on the spectrum is uv radiation. The blue light. Blue light suppresses the release of melatonin in our brains which leads to a lower quality of sleep which in turn can contribute to a variety of negative health effects. There are countless clinical studies that support the harmful effects that blue light can have for people who are prone to headaches or migraine attacks.

Researchers have suggested that there is a specific neural pathway from the eyes to the brain separate from how vision is transmitted that ultimately causes blue light wavelengths to. One concern is that because blue.
