There are many among us who have a hard time going to sleep on time, but yet have to wake up around 5am in the morning for work. Such inefficient sleeping pattern affects everyday life and one’s productivity, needless to say.

But what can be done to improve sleeping pattern. Is waking up at the same every day the answer? Professor Colin Espie at Nuffield Department of Clinical Neuroscience at the University of Oxford and Sleepio co-founder has some insight, reports British online Independent.

“Getting into the habit of a pattern that works well for your personal comfort is the best strategy. We know from experience that everyday will be different, as a result of early meetings or lifestyle changes,” he said.

He advises that whatever time you wake up, you shouldn’t skrimp on sleep, with the amount needed by each person varies from individual to individual.

“Poor or insufficient sleep can affect everything in our day-to-day life, from our mood and how we interact with people to our productivity at work.”

However when it comes to what time to go to sleep, Professor Espie explains that the rules are much vaguer.

“It’s important not to get stuck on the idea of one bedtime that suits all, because different individuals can have different chronotypes. Most of us sit in the middle between being an early bird or a night owl, but there are people who are on either extreme of this,” he said

He explained that each individual “should discover what they personally need and then make this a recurring habit.”
