You Should Stop Doing This Before Bed If You Want To Sleep Through The Night, According To Experts

Using electronics before bed

When you’re getting ready to hit the hay, it’s only natural (and in fact healthy) to do some relaxing activities that will help you unwind at the end of a long day. However, if those activities include scrolling through social media or streaming your favorite show in bed, you’re likely actually setting yourself up for a worst night’s sleep due to blue light exposure. 

“One of the biggest mistakes I see people make before bed is not disconnecting from their electronics,” Greenspan tells us. It all comes down to the role light, and blue light in particular, plays in your body’s hormone production. “The blue light emitted by TVs and cell phones can disrupt our natural sleep hormone, melatonin, making it difficult to fall asleep and stay asleep throughout the night,” he warns.

Smith agrees, explaining further: “When our eyes are exposed to blue light, it tricks our brain into thinking it’s daytime and shuts off melatonin production,” she says. “Our brains naturally produce melatonin to help us sleep. However, if we expose our eyes to blue lights from our cell phones, iPads, or TVs, we will not get the melatonin we need to fall asleep naturally. This could also raise our cortisol levels, making it difficult to sleep through the night.” Yikes!

“Sleeping with or near phones can adversely affect sleep due to the output of blue light as well as the disruption caused by calls, emails, texts, social media, and other app alerts coming through,” Dixon-Peters adds. 

In general, it’s important to keep your circadian rhythm regulated by prioritizing ample amounts of morning light and limiting your exposure to light in the evening. “Light is stimulating and therefore should be off while sleeping–including avoiding blue light from personal devices before bed–and it is beneficial to take in natural light in the morning to stimulate rising,” Dixon-Peter tells us. 

Ultimately, although resisting the pull of your devices can be difficult, it’s in your best interest to set limits before bed. “To get a better night's rest, try to turn off all electronic devices at least 30 minutes before bed. This will help your body relax and signal your brain that it's time for sleep,” Greenspan concludes. Noted!
