A group of doctors from Northwestern University's Feinberg School of Medicine and Rush University Medical School share that sleep tracking devices could do more harm than good. According to experts, depending on sleep devices can make you obsessed with your sleep cycle, which is a real problem called 'orthosomnia'. People suffering from this problem constantly worry about not sleeping well. During the study, while sleep trackers did correct sleep habits, participants relied on the data way too much. There was another side effect. Being obsessed with sleeping patterns often made people lay in bed for longer, just to clock in extra hours and correct the number on the device. Experts suggest that you should depend more on your natural body signals and disconnect from devices at least 45 minutes before your hit the bed.
