In order to take care of children, many parents will open a night light while sleeping. According to a report by the Mother Nature website, a new study by Harvard Medical School found that LED nightlights interfered more with sleep than incandescent lamps.
Charles, a professor of sleep medicine at Harvard Medical School. A. Chessler found that children who touch artificial lights in the evening or in the evening (such as light from electronic devices such as computers) can interfere with their 6-8 hour sleep cycle, resulting in a feeling of jet lag.
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.
