Could Reading At Night Be Impairing Your Sleep?

Reading is one of the top favorite bedtime activities. It is relaxing, can be done laying down, and often puts people to sleep. If you are one of the few who still reads from a physical book made of paper, this activity is a great choice for bedtime. However, if you have joined the masses in the e-reader craze, you may be hindering the quality and quantity of sleep you are getting.



How Electronic Blue Light Affects Sleep

Researchers at Brigham and Women’s Hospital have studied the effects of the short wavelength enriched light that electronic devices produce, called blue light, on the body’s biological rhythms. Circadian rhythms in the body are highly tied with light. Our bodies learn that when it gets dark outside, we sleep. The type of light that electronic devices emit disrupt our internal clocks and trick them into thinking it is daytime. Studies show that the circadian rhythm can be delayed up to an hour when using blue light emitting devices. In addition to disrupting circadian rhythms, e-readers have also been linked to the following:

  • Reduced evening sleepiness
  • Reduced melatonin secretion
  • Reduced next morning alertness
  • Increased length of time to fall asleep
  • Reduced time in REM sleep
  • Increased alertness before bed

Quality of sleep impacts overall health and wellness. The chronic suppression of melatonin, which is a hormone which has a rising level in the evening to aid sleep, is linked to breast cancer, colorectal cancer, and prostate cancer.


Are You Using An E-Reader?

E-readers are any electronic device that emits light. These include iPads, laptops, cell phones, LED monitors, and any other device you can read on that is not a paper book. Even if you are not reading, but instead playing games, checking email, surfing the internet, or instant messaging on these devices, you could still be experiencing the negative effects of using an e-reader before bed.

Children and adolescents are among the top users of electronic devices before bed, and the quality of their sleep is decreasing over time. It is especially important for growing minds to get quality sleep, and enough of it. We recommend keeping these devices out of the bedroom altogether, and choosing a less bright alternative for bedtime, such as reading a physical, paper book. The good news for book lovers is that subjects who read from paper books before bed in the study did not experience any negative sleep effects like those who read from e-readers. Our advice is to limit e-reader use to daytime hours and in other rooms in your house, and at night in bed, stick to paper books.

Client Reviews

"I was especially impressed with Andrew the Respiratory Therapist who reviewed my study with me and answered my questions. Andrew thoroughly explained everything about the Cpap machine-from start to finish. I never felt rushed and was assured I could contact him with any additional questions or needs. Andrew told me he would follow up with a call in a week and he did. I believe this center performed the study appropriately and the added benefit of having Andrew teach me about the machine and what to expect was a bonus."

"I recommend them highly!! I took my 2 year old daughter for a sleep study and was very impressed. Our sleep technician was amazing with her, very patient and kind. The DVD we brought to watch while getting her hooked up got stuck in the TV and they vowed to return it. We got a call the next day checking on our daughter and saying how sweet she was, they mentioned the DVD. Several days later, we received the DVD plus a new copy of the Lion King with a nice note. They are very good at what they do and if they can make a 2 year old feel at ease, they can probably do the same with anyone!!"
