why shouldn t you sleep with red led lights on


In this article, kosoom experts will discuss red light and different light effects on human sleep
By choosing the most appropriate LED light source and controlling its lighting intensity, we can minimize the impact of LED lighting on the sleep environment, both to meet the basic lighting needs and not overly inhibit sleep
Red LED lights may have some adverse effects on sleep

  • mainly for the following reasons.

  • red light will inhibit the secretion of melatonin.Melatonin is an important hormone to promote sleep, the secretion of elevated levels at night to help sleep. The red light will inhibit the secretion of melatonin, so that people produce a more excited mental state, which is not conducive to sleep.

  • red light activates the retina and increases the sense of alertness. Red light has a high degree of retinal activation, which will increase the sense of mental alertness and mobility, making it more difficult for people to fall asleep. Soft yellow light or warm light has lower retinal activation and is more conducive to sleep.
  • red light may affect the biological clock rhythm.
  • Red light may affect the circadian rhythm of the human biological clock, so that people need to wake up at night signal, affecting the normal sleep-wake cycle, resulting in reduced sleep quality or sleep disorders.
  • red light is likely to cause photophysiological stress. Compared with warm light or yellow light, red light is more likely to stimulate the retina, causing light physiological stress, which is also not conducive to the body into a relaxed sleep state.

  • 30-60 minutes of red light exposure can increase melatonin levels and improve sleep quality. However, too much time can have the opposite effect. Therefore, the duration and intensity of red light exposure needs to be moderately controlled. Red light can increase the release of dopamine in the brain, producing a slight euphoric effect and a signal to wake up. Long periods of intense red light exposure may affect the sleep cycle.
  • Red light has also been used to treat sleep disorders, but the mechanism and dose control are not well understood. It should be used with caution and adjusted to individual sleep conditions.

If you want to use red LED lights in the sleep environment, you need to properly control its exposure time and brightness intensity. In general, the use of red LED sleep lights, should not exceed 1 hour, and choose a darker brightness. This can reduce the impact on sleep, but also to meet the most basic lighting needs of the sleep environment. We also recommend consulting a doctor before use, especially if there is a sleep disorder.

  • The effect of different color temperature LED lighting on sleep.

  • 2700K below the warm color light is most suitable for sleep, including yellow light and orange light. These lights have the least effect on melatonin and help you sleep. Should avoid cold light above 3000K, including blue light.
  • The effect of red light is in between. Red light will suppress melatonin to some extent, but not as strong as blue light. Moderate red light is acceptable, but not as ideal as warm light.shopilyd5e5d9bf3700fbcc367687b44e5cab4 1024x1024
  • the brightness of LED lights is equally important. Too strong light regardless of color temperature will be more serious impact on sleep. So choose LED sleep lights, you should choose the color of warm and moderate brightness products.
  • white light contains a variety of spectral, will inhibit melatonin secretion, which is harmful to sleep. Should be avoided in the sleep environment using white light lighting.
  •  green light is similar to the impact of blue light, will also suppress melatonin, which is not conducive to sleep. Recommended to avoid green LED.
  • Warm LED light below 2700K is the best choice for the sleep environment, followed by red light, should avoid the use of cold light and white light. At the same time, choose products of moderate brightness, avoid too long or too strong light exposure, in order to reduce the impact on sleep.
  • Choose soft yellow LEDs to facilitate sleep

  • the use of red LED lighting sleep environment, especially in the early stages of sleep, may have a certain negative impact on sleep. If you need to use the night light during sleep, it is more recommended to choose a soft yellow LED night light, its light is more mild, the impact on sleep is less.
