Japan's latest research: LED lights blue can improve sleep quality

A Japanese research team recently discovered that the blue LED lighting of the LED lighting control can be achieved to improve the role of sleep, which will be used to develop suitable sleeping lighting.

Melatonin is secreted by the pineal gland within the brain natural hormone, secreted in the absence of light at night the largest amount, can help reduce body temperature and pulse, help sleep, reduce the secretion of melatonin morning, people woke up slowly, so it is also called "sleep hormone." Modern society, a variety of lighting equipment and digital equipment will have an impact on the secretion of melatonin, leading to sleep disorders.

Nagoya University and Aichi Prefectural University research team research indicates that blue LED lighting is closely related with the secretion of melatonin, melatonin secretion is the interference of the "culprit." Researchers developed to artificially adjust accordingly blue LED lighting of the LED, and carried out using the test. The use of the test in two weeks, the test subjects improved nighttime sleep; sleep at night is more stable and less likely to doze off during the day. In addition, they also improved cognitive status.

A new study found that blue glasses people sleep better at night, during the day and more spiritual. The glasses can be adjusted by the body clock, people restore normal sleep patterns. Wearing blue glasses a day is able to help.

United States "International circadian science" magazine carried an article saying that the new glasses by the American Institute of Technology researchers design is completed, the top of a spectacle frame miniature bulbs can emit blue light. Glasses itself is transparent, so the wearer can see everything under normal light, but when worn, the lamp will irradiate the eyes blue.

The study involves11 volunteers trying this sleep mode corrective glasses. Some people accept the Blu-ray is strong, some of the weak. The researchers tested the volunteer’s melatonin levels. If the Blu-ray glasses can reduce daytime sleepiness volunteers that their melatonin levels will drop. It was found that only accepts one hour glasses blue light irradiation intensity, you can make melatonin levels were decreased by 35% to 60%. The researchers said the new Blu-ray glasses are comfortable and effective in the treatment of sleep disorders.
