Question

1) "How much sleep do I need? Dr. Lydia DonCarlos from Loyola University, Chicago, one of the experts on the study, says that the circadian rhythm of teenagers naturally shifts to make them feel sleepy later at night and to wake up later. This is a normal phenomenon and nothing to do with being addicted to social media. She warns that teenagers should still try to get enough sleep on a daily basis, rather than building up a sleep debt to pay off at weekends. 'You can never quite make it up', she says. Adults aged 18 to 64 need to sleep for seven to nine hours a night, but some cope on six. For people over the age of 65, the recommended amount is between seven and eight hours, although some survive on five hours sleep (often waking up earlier and napping during the day).
