Harvard University's latest research: LED lights double interference with children's sleep

In order to take care of children, many parents will open a night light while sleeping. According to a report by the US Mother Nature website on January 9, a new study by Harvard Medical School found that LED nightlights interfered more with sleep than incandescent lamps.

Charles A. Chessler, a professor of sleep medicine at Harvard Medical School, found that children who are exposed to artificial light (such as light from electronic devices such as computers) in the evening or in the evening can interfere with their 6-8 hour sleep cycle, resulting in a similar "flying time difference". "a feeling of.

Dr. Chesler's analysis pointed out that the blue light emitted by electronic devices mimics the natural light during the day, which makes the brain always feel the daytime, stimulates the brain to produce cortisol, maintains higher alertness and makes people more awake. The study found that LED lamps stimulated the brain to produce cortisol twice as high as incandescent lamps. Even a short period of exposure to LED lighting during the day may result in a delay of 2 hours in the evening.

LED lights are almost ubiquitous, such as night lights, televisions, computers, mobile phones, and so on. Sleep experts such as Dr. Chesler suggested that it is best to disable the LED lights in the child's bedroom. Once parents find that their child has a problem with their sleep patterns, they should check their "screen time" with LED lights and TV, computer and mobile phone, and intervene early to restore their sleep.
