Regulating and controlling the blue band of LED lamp can improve sleep

Japan's latest research team found that the LED lamp to control the blue light band, can achieve the purpose of improving sleep, which will be used for the development of lighting suitable for sleep.

Melatonin is secreted by the pineal gland in the brain's natural hormone, in the absence of light at night can help reduce the secretion of the maximum temperature and pulse, help sleep, reduce the secretion of melatonin in the morning, people slowly wake up, so it is also called the "sleep hormone". In modern society, all kinds of lighting equipment and digital equipment will affect the secretion of melatonin, leading to sleep disorders.

The research team of Nagoya University in Japan and Aichi Prefectural University, pointed out that the blue band LED and melatonin secretion is closely related to the secretion of melatonin interference culprit "". According to the researchers developed a human can adjust the blue band of LED, and the use of testing.

In the two week of the use of the test, the test subjects sleep improved at night, sleep at night is more stable, and during the day is not easy to doze off. In addition, their cognitive status has improved.

The researchers believe that the invention can be used to create "sleep friendly" lighting fixtures.
