The Impact of Light on Sleep
Light plays a huge role in affecting our sleep. Our bodies follow a natural cycle known as the circadian rhythm. This is an internal 24-hour clock that regulates various body functions like core body temperature, hormone production, and even sleeping and waking patterns. Being exposed to adequate light during the day helps keep our circadian rhythm in check, and inadequate light exposure can lead to sleeping issues.
There is no escaping light. It enters our bodies even when our eyes are closed. Therefore, light exposure during the night can disrupt sleep. This can have a huge impact on a person’s health. Studies have found that light exposure during the night increases the risk of certain diseases.
The body’s natural cycles are affected by the presence or absence of light. Inadequate light exposure can lead to poor sleeping habits, which can in turn lead to other health issues. Not only should one get enough light during the day, but it is also important to minimize exposure to light during the night for optimum health.
Light During the Day
Daytime light exposure is fundamental in helping our circadian rhythm stay in order. During the day, the body should get exposure to natural sunlight. This is the most beneficial type of light for maintaining one’s internal clock. Natural sunlight helps increase energy and alertness during the day.
During the day, work and living environments should also be well-lit. Ambient daylight should be maximized and adequate overhead and accent lighting should be provided. However, one should also take appropriate steps to reduce the amount of sky light entering ones living and work space. This will help in best controlling the amount of light one is exposed to.
Light During the Night
Light exposure can have a negative impact on sleeping patterns when it occurs during the night. This is because this type of light disrupts melatonin production. This hormone is responsible for inducing sleep and maintaining the body’s natural sleep-wake cycle. Studies have found that even small amounts of light can lead to disturbed sleep.
- Avoid bright lighting when it is time to go to bed
- Utilize blinds to reduce light exposure
- Try to keep all electronics off and out of the bedroom
- Limit your exposure to bright screens before bed
Conclusion
Light plays a huge role in influencing our health. It is responsible for affecting our sleep and can also increase our risk of certain diseases. Therefore, it is important to ensure we are exposed to the right kind of light during the day and minimized our exposure to light during the night. This will help us sleep better and have better overall health.
