It causes depression.Perhaps screen time is one of many things to blame for an alarming 2.8 million adolescents aged 12 to 17 in the U.S. alone being diagnosed with major depression in 2014. Psychological experts agree, saying that too much screen time damages the brain, leading to, among other things, impaired cognitive functioning – specifically impaired dopamine function, which plays a major role in the onset of depression.
It can ruin a good night's sleep.Too much screen time has also been linked to sleep deprivation. The reason for this is that the body reacts to screens and the tasks we use them for, such as gaming and communication, by releasing cortisol, a stress hormone. This produces conditions that are far from conducive to sleep. The light emitted from screens also prevents the brain from emitting melatonin, a chemical which your body uses to prepare for sleep. Continued use of screens before bed can reset your body's internal clock, changing the time you are able to fall asleep.
It's an attack on your senses.Health experts have written many a thought-provoking pieceon the prevalence of too much sensory information in our modern society. One of the places you can see this most clearly is in the way television shows and movies are created. Flashing, bright lights, loud sounds and tantalizing commercials – all have been hypothesized by experts to lead to everything from headaches to skipped meals. The amount of time children are spending exposed to the screens that produce such stimulus-laden experiences can even lead to ADHD.
What's the solution?Limit your child's screen time. You can do this in the following ways:
- Lead by example. Don't tell your kid not to spend so much time in front of a screen, then sit for hours in front of the TV when you come home. Show your child that life can be enjoyed away from a screen.
- Be firm. You are the parent, you make the rules. Even if your child mopes and whines when you impose limited viewing times (one or two programs a day), that's OK. You're doing it because you want the best for them.
- Give your kids something else to do.Don't leave a void where television and gaming used to be. Give your children other things to do by getting involved in their lives and engaging in fun activities with them.
