How does blue light exposure before bed affect sleep quality?

Blue light exposure before bedtime can negatively affect sleep quality. This type of light, commonly emitted from screens like phones and tablets, can interfere with the body's natural sleep-wake cycle.

1. Effect on Sleep Hormones: Blue light can suppress melatonin, a hormone that helps us sleep. When melatonin levels are low, it can be harder to fall asleep and stay asleep.

2. Impact of Devices: Studies show that using devices like smartphones and eReaders that emit blue light before bed can delay sleep onset and reduce sleep quality. People may take longer to fall asleep and experience less restful sleep.

3. Recommendations: To improve sleep, try reducing screen time before bed or using settings that reduce blue light on your devices. This can help your body prepare for a good night's sleep.
