How Screen Time Affects Body WeightHow Screen Time Affects Body Weight
While many studies focus on how screen time affects body weight in youth, there is evidence that the same risks apply to all age groups. One study found that increased time spent watching television was significantly associated with increased body weight in adults. Other studies suggest that risks for obesity, diabetes, and heart disease in women increase for every two hours of television watched daily. Limiting your screen time and paying better attention to how it influences your appetite and actions can help you better control your body weight.
Food ads trigger cravings.
Have you ever taken note of your hunger or cravings while watching television commercials or seeing food online? If not, start taking note. Simply seeing a food ad can lead to thoughts about food and take you straight to the kitchen or the fast food drive-thru. Reducing screen time reduces your exposure to these triggers and may help you better control your cravings.
Screen time can take the place of exercise.
Lacing up your tennis shoes and hitting the gym takes more organization and commitment than it takes to sit down and watch a television show or do some research online. It’s not surprising that screen time often takes the place of exercise, leading to fewer calories burned.
Screen time leads to mindless snacking.
Distractions like the television, laptop, or your smartphone can lead to overeating. When you are watching a movie or working at the computer, it is easy to grab snacks by the bag or box for convenience. One handful quickly leads to two and sometimes half the box. What’s worse is that not focusing on the food or truly enjoying it may leave you unsatisfied even after eating hundreds of extra calories.
Screen time can interfere with sleep.
Screen time activities can be addictive. You may stay up to finish watching a show or to play a few more rounds of your favorite computer game, which eats into the hours of sleep you need each night. In addition, research shows that light from electronic devices may lower levels of important hormones that help regulate sleep patterns. Not getting the recommended seven to nine hours of sleep each night can influence appetite hormones that lead to hunger and weight gain.
