Night owls can become larks in just three weeks

Night owls are at a disadvantage in modern life because working days cater towards morning larks, with their earlier sleep/wake cycles. This leaves night owls suffering from lack of sleep, daytime drowsiness and poorer mental wellbeing.
A team of researchers from the UK and Australia carried out a small study to see if night owls could make tweaks to their routine to bring forward their sleep and wake times, without impacting their total snoozing duration. Over the course of three weeks, 22 participants – who had an average bedtime of 2:30am and an average waking time of 10:15am – went to bed two to three hours earlier every day, and set their alarms for two to three hours before their normal waking time. They were asked to eat breakfast as soon as possible after getting up, and to get lots of sunshine in the morning, while reducing daylight exposure in the evening. They also had their dinner no later than 7pm.
At the end of the study, reaction times and grip strength in the participants had improved in the morning, suggesting better mental and physical performance. Breakfast was eaten more frequently and participants reported improvements in mood, a reduction in stress and less daytime sleepiness.
