An amazing amount of research is being done on the subject of sleep -- especially among adolescents. One of the hardest things in the world, apparently, is to get teenagers into and out of bed on time. In an Australian study, a school-based programme of four 50-minute classes over four weeks gave two groups of students aged 15 to 17 advice about healthy sleep habits along with other input on personal well-being, including healthy eating and exercise. Those in the classes were compared with control groups who did not do the programme.
The programme taught students the benefits of minimising caffeine and alcohol intake, reducing stimulating activities at night, getting out of bed at a consistent time each morning (even on weekends) and getting exposure to bright light in the morning to help reset their body’s biological clock.
