Is Sleeping with the Lights On Good for You?

by Morgan Spencer

Sleeping with the lights off is the norm to many people who grew up with the catchphrase, "lights out." Although this hack isn't new, there is more scientific proof backing this sleep hygiene, which makes us wonder why some people still sleep with the lights on. According to research, many Americans sleep with a small amount of light penetrating the room. Based on scientific research, this moderate amount of light could be harmful.

We are surrounded by lights from multiple sources – televisions, computers, cell phones, etc. These gadgets emit blue light that is detrimental to good sleep at night. So, the next time you decide to leave the lights on, consider the following.

Why Sleeping with the Lights on Isn’t Good for You

Poor concentration and alertness: Sleeping with the lights on can affect your sleep quality. We are all too familiar with the fact that lack of sleep leads to poor concentration and mental alertness (regardless of how many coffees you consume). Unfortunately, this means you can be prone to accidents or falling.

Depression: Exposure to blue lights can affect your mood and cause severe depression. This happens because the brain finds it difficult to achieve deeper sleep with the lights on. The effect of this is mood changes and irritability.

Weight gain: Studies have found that excess weight was prevalent in women who slept with television or lights on. The same studies show a relationship between food intake and lack of sleep: those who sleep less are more likely to eat more.

It can lead to migraines: If you are fond of using gadgets before sleeping and you experience migraines, they could be linked. Electronics emit blue light that affects the body’s ability to eliminate toxins. This inability can cause migraines and eye strains.

It can lead to high blood pressure: There was an interesting study which revealed that people exposed to an excessive amount of light at night can be at risk of high blood pressure.

Are there Any Benefits to Sleeping with the Lights on?

While there are several reasons you shouldn't, sleeping with the lights on is reasonable if you want to take a quick nap during the day. Overall, the risks of sleeping with the lights on outweigh the benefits.
Getting the right amount of quality sleep is essential. Sleep itself will;

  • Repair the brain and body
  • Allow for better muscle recovery
  • Fight illnesses
  • Improve mood

However, you will achieve the maximum benefits if you sleep without lights on since sleeping with the lights on affects the circadian rhythm. Therefore, the brain produces fewer melatonin hormones for sleep.

Work Your Way to “Lights Off”

So, if you’re in the “lights on” camp, perhaps it’s time to learn to start sleeping with the lights off. The benefits are immense, and your overall health is improved. If you have sleep issues or have difficulties sleeping with the lights off, incorporate the following sleep habits.

  • Keep electronic gadgets out of the bedroom.
  • Use dark blinds to reduce light penetration.
  • If you find it difficult to sleep with the lights on, wear blue light-blocking glasses to intercept the light.
  • Use a comfortable mattress and pillow to aid your sleep.
