Students who come to school sleepy may be tired because they wake up during the night to check social media, according to a recent study by British researchers which looked at data for more than 900 young people between ages 12 and 15. Data shows 1 in 5 students reported waking up to check social media. The National Sleep Foundation suggests that teens get between 8 and 10 hours of sleep per night. Making sure that a regular sleep pattern is kept is extremely important so that teens can maintain their internal clock and function optimally.
