Q: Is there any link between screen time and sleep disorders in children?

A: Melatonin is a hormone which regulates our body’s sleep. It’s production is very sensitive to light from screens. The light produced by phones and tablets suppresses it. As a result, using gadgets before sleep negatively affects children’s sleep and can cause insomnia and other sleep disorders. The general rule in this case is “the more screen time – the less sleep time or less productive sleep time”.

Screen time and sleep problems

Scientists say that good performance during the day is directly linked to the quality of our sleep. If a person doesn’t sleep enough or the sleep is not deep enough, the immune system is gradually destroyed. This can result in frequent headaches or even mental disorders. Toddlers who spent time playing on smartphones and tablets slept about 15 minutes less for every hour of active touchscreen use. Children and young people may experience some problems with concentration the next day which is not good for their ability to study.

Quality of children's sleep

Problem: Exposure to a smartphone or tablet screen is very often associated with lower quality sleep, nightmares, and morning depression. Extensive use of gadgets before going to bed can also negatively affect pre-sleep routines and preparations.


Solution: Kidslox Daily Limits and Schedule features help you to set limits on your children’s screen time. Their gadget will shut down when they used all the screen time you allowed them to have or when it’s time to go to bed.

Little children are even more vulnerable

Problem: Toddlers and little children who use touch screens for only 25 minutes a day sleep less than usual.

Solution: Using Kidslox you can remotely lock your child’s device any time you want in order to protect your little ones when they are playing with electronic gadgets.

Concentration and study problems

Problem: Many applications are so involving and are designed to fully absorb children’s attention. As a result, they often do not notice how much time they spend at the screen.  

Solution: With Kidslox you can block certain apps and web sites to be sure that your child is using educational apps and not playing games late night or when at school.
