![]() Researchers say those results show that computer users who work or play at night in front of a bright display might lose sleep because performing an exciting task late at night may alter the normal nocturnal changes in melatonin and body temperature associated with a person's biological clock. But there was no difference in melatonin levels during the boring tasks.Īlthough the body temperature dropped at night under all conditions, working in front of a bright computer screen caused the computer user's body temperature to be significantly higher than when it was performed using a dimmer monitor. When you browse in Dark mode or Dark theme in Chrome, your homepage, toolbar, settings, and some other pages will be dark. Melatonin levels were lower after performing the exciting task in front of a bright display than in front of a darker one. Researchers Shigekazu Higuchi and colleagues at the Akita University School of Medicine in Akita, Japan, found that melatonin production was significantly affected by the brightness of the computer screen as well as the type of task performed. They were then asked to perform either an exciting task (a video shooting game) or a boring task (simple math) using a computer with either a bright or dark display monitor on alternating nights between 11:30 p.m. for a week before the start of the experiment. and go to bed between midnight and 1 a.m. Seven healthy male computer users with an average age of 25 were told to wake up between 8 and 9 a.m. At the top of the Display tab in Settings, under the Color heading, is the new Night Light feature. If you’re up-to-date, launch Settings from your Start Menu and select System > Display. If you're using a schedule, Night Shift automatically turns off at the scheduled time. To enable Night Light, first make sure you’re running the Creators Update, which should be Version 1703 or newer. If Night Shift is off, select the checkbox to turn Night Shift on until 7 a.m. You can enable sunrise/sunset features in options, set different color temperature and screen brightness for day and night. In this study, published in the May issue of the Journal of Applied Physiology, researchers tested the effects of computer use at night on melatonin production as well as a variety of other factors known to affect a person's biological clock, such as body temperature and heart rate that are known to drop during sleep. Schedule: Create a custom Night Shift schedule or have Night Shift turn on automatically from sunset to sunrise. Researchers say exposure to light is thought to alter the amount of melatonin produced, and a decline in melatonin production is often blamed for sleep problems in the elderly. Melatonin is a hormone in the body that helps regulate a person's sleeping and waking hours. A new study shows that the bright light of a computer screen may alter the body's biological clock and suppress the natural production of melatonin that's critical to the normal sleep-wake cycle. If it feels uncomfortable to look at the screen, turn off the night light.JPlaying a video game or finishing up some work on computer before bed may keep you awake long after you turn the computer off. It is normal that the screen appears yellowish or has color deviations when the Microsoft night light is turned on.If it feels uncomfortable to look at the screen, disable eye comfort mode. It is normal that the screen appears yellowish. When eye comfort mode is enabled, the computer automatically adjusts the color temperature.Once the ambient light frequently changes, such as if the computer is flipped over multiple times in an indoor lobby or in a dark environment, the screen changes brightness accordingly and it looks like there is a color deviation. When the automatic screen brightness adjustment function is enabled, the computer screen automatically adjusts its brightness based on the ambient light.Computer screens in the same batch may also vary slightly.The color of the computer screen varies depending on the production batch.The computer features an industry-leading screen that has passed strict quality tests and optical inspection before delivery to ensure that it meets Huawei's standards.
