So I have heard that to much exposure to specifically blue light can make it harder to sleep but how?I mean it’s light and blue is seen as a calming color so how can exposure to to much blue light make it harder to sleep?
In: Biology
Blue light can affect sleepiness because it interferes with the body’s natural sleep-wake cycle, also known as the circadian rhythm. Our bodies have an internal clock that helps regulate when we feel awake and when we feel sleepy.
Exposure to blue light, especially from electronic devices like smartphones, tablets, and computers, can trick our brains into thinking it’s still daytime. This is because blue light suppresses the production of melatonin, a hormone that helps regulate sleep. When our brains perceive blue light, they interpret it as daylight, which can make us feel more alert and less sleepy.
If we’re exposed to blue light in the evening, such as when using electronic devices before bedtime, it can disrupt our natural sleep-wake cycle by delaying the onset of sleepiness and making it harder to fall asleep. This can lead to sleep problems like insomnia or poor sleep quality.
To minimize the effects of blue light on sleepiness, it’s helpful to limit exposure to electronic devices with screens, especially in the hours leading up to bedtime. Some people also use blue light filters or wear special glasses that block blue light to reduce its impact on sleep. Additionally, creating a relaxing bedtime routine and optimizing the sleep environment can help promote better sleep.
