Do you check your cell phone after you’ve gone to bed? If so, you’re not alone. A new poll in the United Kingdom found that 45% of young people, ages 11 to 18 check their phone at night and one in 10 of them check it at least 10 times a night. About 94% of those were on social media, 75% of them were listening to music, and 57% were watching films. About 42% of them keep their phone next to their bed all night. The survey went even further to investigate how mobile use at night is affecting their daytime activities and the results were eye-opening. About 25% of them say they feel tired during the day because of their cell phone overuse at night and 68% say that it affects how they do in school.
