Introduction
Artificial light has become ubiquitous in our modern lives. It is used to light up our homes, offices, and public spaces, and it is also used to extend our days beyond daylight hours. However, it has been known for some time that artificial light can affect our sleep, and that it can have both positive and negative effects on our overall health and wellbeing. In this article, we will discuss how artificial light affects our sleep and what we can do to minimize its impact.
How Does Artificial Light Affect Sleep?
The most obvious way in which artificial light can affect our sleep is by suppressing the production of melatonin, a hormone that helps regulate our sleep and wake cycles. Exposure to artificial light, especially at night, can reduce the amount of melatonin our bodies produce. This can make it more difficult to fall asleep and stay asleep, leading to fatigue, irritability, and other sleep-related issues.
Additionally, artificial light can disrupt our circadian rhythms, which are the 24-hour internal clocks that regulate our natural sleep-wake cycles. When our circadian rhythms are disrupted, it can further affect our ability to fall asleep and stay asleep. This can lead to a range of health issues, such as insomnia, depression, and even obesity.
What Can We Do To Minimize The Impact Of Artificial Light?
There are several steps we can take to minimize the impact of artificial light on our sleep. First, we should try to avoid exposure to artificial light at night. This means avoiding screens (TVs, computers, smartphones, etc.) at least two hours before bedtime, and turning off the lights in our bedroom. Additionally, we should use blackout curtains or window shades to block out light from outside sources, such as streetlights or the moon.
Second, we can use blue-light blocking glasses during the day and night. These glasses have special lenses that filter out blue light, which is the type of light emitted from our devices and other artificial lighting sources. Wearing these glasses can help reduce the amount of blue light our eyes are exposed to and can help keep our circadian rhythms in check.
Finally, we can try to adopt a healthy sleep schedule. Going to bed and waking up at the same times each day can help keep our circadian rhythms in sync and can make it easier to fall asleep and stay asleep.
Conclusion
Artificial light can have a significant impact on our sleep and overall health. To minimize its effects, we should try to limit our exposure to artificial light at night, use blue-light blocking glasses during the day and night, and adopt a healthy sleep schedule. By following these steps, we can maximize the quality of our sleep and improve our overall health and wellbeing.
