Because batteries heat up when charging, it's also a major fire risk charging your phone on your bed or under your pillows while you sleep – forget about those brain cells, you'll burn down the house! Try placing your phone in a saucer while it charges to avoid starting any inadvertent fires.
Don't charge any electrical devices, including phones and tablets, on your bed or under your pillow while you sleep as they could overheat and cause a fire. If possible, avoid charging devices unattended or overnight, and when necessary only charge them on a hard surface such as a desk.
It puts our health at risk due to emitted radiation
Owing to this, keeping cell phones close to the head for prolonged periods can lead to headaches, muscle pains, and other complicated health issues.
Your phone should be at least three feet away from your bed to limit exposure to radiofrequency energy. If you need to use your phone as an alarm, turn on airplane mode to prevent it from sending or receiving calls and text messages. During the day, carry your phone in a purse or bag, rather than in your pocket.
Wireless radiation impacts sleep in several ways. Research has shown that exposure to wireless radiation results in delayed entrance into deep non-REM sleep and decreases time spent in certain sleep stages.
Cell phones emit low levels of non-ionizing radiation when in use. The type of radiation emitted by cell phones is also referred to as radio frequency (RF) energy. As stated by the National Cancer Institute, "there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans.
Along with reducing melatonin levels, nighttime exposure to blue light can reduce the length of REM sleep, which can make you feel less alert and take longer to be fully awake in the morning. In bed, or even before it, researchers have found exposure to the light from screens can impact sleep.
Practically speaking: Any part of your body holding the phone or glued right up to next to your cellphone, is getting the heaviest dose of exposure. Keep it out of your hands anytime you can and a good 12" away from your face and eyes is a good rule of thumb for "safer" exposure levels.
Try putting your phone in another room while you're sleeping. Or, if you need your phone in your bedroom with you for the alarm clock, make sure it's at least three feet away from you.
“Airplane mode”, also known as “flight mode,” is a setting on your wireless device that stops the microwave radiation emissions. It turns antennas to OFF. Learning how to use airplane mode is one of our most important tips.
To watch movies or listen to playlists on your phone, download them first, then switch to airplane mode while you watch or listen. Don't sleep with your phone in your bed or near your head. Unless the phone is off or in airplane mode, keep it at least a few feet away from your bed.
If you plan to sleep with your phone next to you on an airplane, it is highly recommended that you turn it to airplane mode. This will help to reduce the potential for any radiation exposure as most smartphones still emit some level of EMF radiation even when they are not in use.
Batteries decay from the moment you start using your new phone. This means they gradually lose their ability to hold a charge. By charging your phone overnight, you're increasing the amount of time it spends with the charger. As a result, it degrades the capacity much sooner.
With a sealed battery and a modern charger it may often not be a problem, but the possibility of danger exists. Modern sealed batteries are generally not rated to withstand substantial pressure. If "gassing" occurs due to overcharging they will almost certainly "vent".
Using your phone a lot while it's charging can also cause the lithium ion battery to degrade faster than it would otherwise. That's because both using your phone and charging your phone causes the battery to heat up. When you do both at the same time, it heats up the battery and puts a lot of stress on it.
Sleep deprivation effects:
Phone can reduce our sleep quality and quantity with vibrations, effects of late screen exposure, and electromagnetic radiation. Sleep being a vital part of your health, sleep deprivation or reduced sleep quantity and quality is terrible for your overall health.
Is it harmful to health/brain? It is completely safe for your brain and your health to leave your phone by your body when you sleep. The myths about radiation and any other story you've heard about phones being dangerous for your health are just that - myths.
In skipping these states and checking your phone right after waking up you are priming your brain for distraction. Seeing or reading something negative first thing in the morning can trigger your stress response and put you on edge for the rest of the day.
While screen time may not cause permanent eye damage, they do make your eyes temporarily dry and blurry. To prevent that, the American Academy of Ophthalmology recommends that you sit about an arm's length from the screen, and take 20-second breaks every 20 minutes.
In terms of comfort for your eyes, it's recommended that you keep your screen a minimum of an arm's distance away and increase the font size, to reduce eye strain. Eye experts also place importance on the “20-20-20 rule”. Every 20 minutes, look at an object 20 feet away, and focus your eyes on it for 20 seconds.
2. Keep a Sensible Distance. You should be able to see everything on your phone screen from between 16 and 18 inches away. Don't hold your phone too close, but if you find yourself bringing the phone closer, consider zooming in on your screen instead.
Eye Strain and Headaches - Too much time spent looking at screens can cause fatigue or discomfort in your eyes as well as dimmed vision. Glare on screens and the brightness of the display can place further strain on your eyes. Eventually, this strain can lead to headaches.
"Simply put, hair is at its most vulnerable when wet. Sleeping with wet hair can lead to a host of problems for the scalp: unwanted bacteria, fungal infections, skin irritation, itchiness, dryness, redness, and dandruff," says hairstylist Miko Branch, co-founder of hair care brand Miss Jessie's.
