Here are some reasons why we do not recommend bright (especially blue) light in the evening:
- Bright light in the evening, particularly blue light from electronic devices, suppresses the body's production of melatonin, a hormone that helps regulate sleep.
- Exposure to bright light in the evening can shift the body's circadian rhythm, leading to difficulty falling asleep, disrupted sleep patterns, and potentially low-quality sleep.
- Studies have shown that exposure to bright light in the evening may also negatively affect mood, cognitive function, and overall health.
- Using electronic devices with bright screens before bed has been shown to decrease overall sleep quality and increase the time it takes to fall asleep.
To do
- To improve your sleep quality, mood and alertness during the day, make sure to expose yourself to plenty of bright light during the day.
- Use warm, dim lighting in the evening, such as amber or red lights.
- Dimming the lights in the evening and avoiding electronic devices for at least an hour before bed can help promote better sleep and overall well-being.
- Stop using bright blue light at least 1-2 hours before bed to allow your body to produce melatonin and prepare for sleep naturally.
- Consider using blue light-blocking glasses if you need to use electronic devices in the evening.
