Roger Federer says having enough sleep leaves him with a “beautiful feeling” and is key to avoiding injury.
According to the NHS, sleep deprivation can have “profound consequences” for physical health and they say “a solid night’s sleep is essential for a long and healthy life”.
And clearly, Federer, who has won over $126million (£102.9m) in career prize money, has been getting his eight hours in regularly.
Federer’s most serious injury came in 2016 when he needed surgery on his knee after an accident as he made a bath for his kids.
But he bounced back from that to win three Grand Slams titles within five tournaments.
Speaking in an interview with Uniqlo.com, Federer has asked how he stays healthy with all the travelling he has to do.
And the 38-year-old said good sleep is significant to not being sick or injured.
“Sleep is really important,” Federer said.
“When you get enough sleep, you wake with all this energy, and that’s a beautiful feeling.
“Sleep deprivation is the worst. It makes you cranky. Next thing you know, you’re sick or injured.”
In a wide-ranging interview featuring 30 questions, Federer opened up on a number of topics.
Federer is well known for staying cool on the court and rarely displaying his frustrations.
And the Swiss star said staying positive is the mindset he prefers to believe in.
“I try to stay positive. There’s always light at the end of the tunnel,” he added.
“Things can always change. If the opponent plays a better game, I accept the situation for what it is and move on to the next one.”
