Studies have shown that the blue light emitted by your smartphone is bad for your vision. But it can be bad for your sleep, too. Exposure to blue light can affect your internal body clock and throw off your circadian rhythm. This rhythm is in tune with light and dark.
Sleeping with your phone can disrupt your sleep cycle, stimulate your mind, and otherwise prevent you from getting a good night's sleep.
Mistake: Sleeping with your cell phone
Some people are so attached to their cell phones that they sleep with them on their nightstand or even under their pillow. Bad idea. Cell phones pump out electromagnetic radiation whenever they're on - which means sleeping with one nearby boosts your exposure all night long.
Yes, unless you are absolutely sure your teenager is able to put the phone away (and not pick it up) at bedtime. That's because screens and sleep do not mix. The light emitted by the typical screen inhibits the production of melatonin in our brains. Melatonin is the chemical that allows us to fall and stay asleep.
Taking away a teen's phone interferes with their social life, which can drive a wedge between parent and teen. It's helpful to make the punishment related to the misbehavior, so taking away your teen's phone for a misbehavior like breaking curfew doesn't usually make sense.
Your phone should be left outside the bedroom when you decide to sleep. However, if you rely on your phone as an alarm clock, place it somewhere as far as possible from the bed, and turn off any notifications unrelated to the alarm clock.
Tips: Stop using electronic devices 30 minutes before bed. The National Sleep Foundation recommends that you should stop using electronic devices, like your cellphone, at least 30 minutes before bedtime. Instead, grab the book that's been tucked away in your nightstand and start reading before bed.
Most people tend to hold their cell phones only about 8 inches from their faces. Not good. Try holding yours at least 16 to 18 inches away from your eyes to give your eyes a break. It might feel funny at first but shouldn't take long to get used to.
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.
Cell phones emit low levels of radio frequency energy, a type of non-ionizing radiation. The available scientific data on exposure to radio frequency energy show no categorical proof of any adverse biological effects other than tissue heating.
Get to Know Airplane Mode
“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.
When a phone or other device is held close to one's face, it forces the eye to work harder than usual to focus on text, says Mark Rosenfield, an optometrist who published research on the topic in The Journal of the American Academy of Optometry in 2011. The discomfort can eventually result in fatigue.
Unless you're ready to go “man-purse” then you better find a pocket because that's all we guys have. Scott Kinnaird, 50s, executive chairman, A La Mode Inc.: If you don't already wear pants loose enough to carry a cellphone in your front pocket, you need to start, because that's where men should carry their cellphone.
“Looking at the phone immediately takes you away from yourself. Before you have even registered your state of mind or how your body is feeling this morning, you're off into other people's stories, others' needs of you, and what the next demand might be.”
Device screens produce blue light, Dr. Cooper says, which is the part of the light spectrum most active in our sleep cycle. Stimulation of this part of the brain suppresses production of melatonin, making it difficult for many people to “turn off” their brains and fall asleep.
Blue light has the strongest impact. Exposure to blue light (and white light, which contains blue light) during the sensitive period can make it difficult for you to fall asleep and stay asleep. Exposure to white light during the day can have positive effects, including boosting alertness and mood.
"The American Academy of Pediatrics strongly opposes striking a child for any reason. If a spanking is spontaneous, parents should later explain calmly why they did it, the specific behavior that provoked it, and how angry they felt. They also might apologize to their child for their loss of control.
Disrespect from children and teens can be shown in a variety of ways - the most common being backtalk, complaining, arguing, attitude, or just plain ignoring.
The first thing to remember when responding is to stay calm. It can be tough to hear that level of disrespect. But raising your voice or saying disrespectful things back will only make things worse. Take a deep breath and don't say anything until you're calm enough to choose productive words.
The symptoms most commonly experienced include dermatological symptoms (redness, tingling, and burning sensations) as well as neurasthenic and vegetative symptoms (fatigue, tiredness, concentration difficulties, dizziness, nausea, heart palpitation, and digestive disturbances).
While it does turn off Wi-Fi and cellular services, airplane mode doesn't turn off GPS (a different technology that sends and receives signals from GPS satellites). You'll have to disable GPS on your device and turn on airplane mode to prevent your phone from being tracked.
