Any Olympic athlete will tell you how important exercise and sticking to a healthy diet is, but some experts (and even some athletes) say sleep is just as important for overall performance.
According to a recent study by Mitacs, an organization whose aim is to build research-based partnerships in Canada, 77 per cent of participating athletes were satisfied with the quality of their sleep after making simple changes to their routine.
Study author and physiologist Amy Bender created a very specific sleeping plan for each member of Team Canada's women's eight rowing team. From small changes like going device-free before you go to bed and fitting in naps, Bender says most athletes had typical sleeping routines before the study.
“What we found was that not only were the athletes not getting enough sleep at night, but they also weren’t napping, which is very important for athletes,” Bender says in a statement. “As well, 90 per cent of the team members were using technology before bed, which has been proven to affect the quality of sleep.”
One of the Canadian rowers was 27-year-old, London, Ont. native, Natalie Mastracci, who is currently competing in the Rio Olympics with the rest of the team.

Mastracci tells The Huffington Post Canada that before the study, she usually slept for five to seven hours, even though she knew she should've been aiming for nine. After sticking to Bender's plan (which you too can follow in the slideshow below), she noticed changes right away.
"It was such an incredible and significant change of my overall attitude," she says. "I didn't want to believe just sleeping more would help everything, but it really did. I was in a better mood at the beginning of practice... and I can get one per cent more out of [that] practice," she says.
Mastracci says even making a small change like getting into bed earlier can make a significant change.
"You can do these things anywhere, even if you are mobile," she says.
Karina LeBlanc, a retired soccer goalkeeper who represented Canada in two Olympic Games and who is now in Rio for Yahoo! Canada Sports, says she would aim to get at least eight hours of sleep preparing for the Games.
"Sleep is just as important as your nutrition, just as important as your training, so if you cut corners on your sleep you might as well cut corners in the gym or on the field," she tells The Huffington Post Canada. "I still try to get that eight hours because that’s what my body knows."

When prepping for the Olympics, LeBlanc says she was told to go device-free before bed and these days she tries not to watch television before resting.
"I still think that gets your brain going, even though I might be watching a show that requires no thought like 'The Bachelorette,'" she says.
These days LeBlanc as well as Mastracci aim to stick to their sleeping schedules, even when they're not training.
"I'm not going to lie, there are some days where there’s so much to do, but I'm just mindful about how important it is to find that balance," LeBlanc says. "I may not have perfected that balance, but I know what I'm aiming to accomplish."
