Being attached at the hip to cell phones is not just for teenagers anymore. People of all ages use their smartphones constantly. These versatile tools are great for entertainment, but they also help us to share ideas and get work done in a more efficient manner. Despite all of those benefits, multiple studies have shown that cell phones should be kept out of our bedrooms. Why does it matter?

Too Many Distractions For Restful Sleep

Sufficient sleep is an essential aspect of a healthy lifestyle, and cell phones in the bedroom lead to a lack of sleep. People who keep their phones within reach while they are lying bed are likely to use their phone when they should be sleeping. It is not uncommon to wake up in the middle of the night. Without a cellphone close by, a person is more likely to close their eyes and eventually go back to sleep. With a phone nearby, a person is at risk of getting lost in the black hole of playing games and watching videos for hours on end. 

The activities that are being done on a phone can also hinder a restful night of quality sleep. Social media can be fun, but it can also put a user face to face with content that is upsetting or disturbing. It’s more difficult to relax and go to sleep after reading a tear-jerking story about a tragic event. Checking work emails before bed is also very counterproductive for going to sleep. This makes the mind race trying to plan activities and solve problems for the next day.

Counterproductive, Possibly Harmful, Emissions

Even for people who have enough self-control to put the phone away when its bedtime, using a phone before bedtime can greatly reduce sleep quality. The screens on most smartphones emit blue light. Blue wavelengths signal to the body that it is time to be up and active. When these lights are viewed close to bedtime, the body believes that it is time to wake up rather than go to sleep. These lights stop all of the inner processes, such as producing melatonin, that helps the body fall asleep. Using a smartphone before bed is as counterproductive as trying to fall asleep with sunlight shining into your eyes.

Science has yet to prove a concrete link between radiation exposure from smartphones and increased rates of cancer, but it is an established fact that radiation is a carcinogen. Whether it comes from an x-ray, a cell phone, or from a spill of some hazardous material, humans are healthier when their exposure to radiation is limited. If a cellphone is on, it is emitting radiation, and the human body can absorb radiation. Phones have been proven to emit higher levels of radiation when connected to Wi-Fi or low on battery power. Since most people connect to Wi-Fi in their home and many people do not charge their phone until the end of the day, its likely that a phone emits even more radiation than it usually does around the time its user heads to bed.

Many people have the habit of sleeping with their phone beside them in bed, underneath their pillow or resting close to their heads on a nearby nightstand. When a phone is kept so close to the human body, that person is absorbing radiation, however small the doses may be, every single night.

When the cellphone is kept outside of the bedroom, there is no risk for anything intruding on sleep time. For a relaxing night of sleep with reduced radiation exposure, let cellphones spend the night outside of the bedroom.
