Why Shouldn't You Watch TV Before Bed?

For some, falling asleep with the television on is a nightly ritual. In fact, about 50 percent of adults do just this, according to Telegraph online. The question is whether this habit is good for you. Most experts agree that for adults -- and especially children -- it is not healthy. Limiting your television time in general, and in particular before bed, is recommended.

Sleep Habits Disturbed

• Waking up more often or taking a long time to fall asleep are the results of nighttime television watching. Especially if the content of what you are watching is exciting or violent. According to the University of Maryland Medical Center, television before bed is simply too stimulating. Reading or taking a bath before bed is more likely to lead to a full night's sleep.

Chronic Health Issues Develop

• When the total amount of time that you sleep is jeopardized, chronic health issues such as heart disease or obesity develop. Watching television before bed leads to shortened sleep duration, according to Dr. Mathias Basner from the University of Pennsylvania's Sleep and Chronobiology Center. People are simply not getting enough sleep because they are distracted by TV shows and put off sleep.

Mental Fatigue Happens

• A low alertness level is a result of lack of sleep. If you stay up late watching a favorite television show, you are not getting enough rest. Sleep is designed to allow the body to recharge and shut down. Your muscles and brain need a break. Being foggy and out-of-touch the next day can be lessened by turning off the television at night.
