A good night's sleep is highly regarded as being the key to getting the best out of your day, and with Lewis Hamilton's F1 status firmly rooted in the far reaches of the stratosphere, it is no wonder he is looking to NASA for help with his sleep.
The F1 schedule sees the teams travel to a vast array of countries on a route that spans the entire planet, and as a result, the reigning champion racks up a lot of air-miles throughout the course of the season.
As a result of these extensive flight plans, Mercedes have enlisted a team of experts in the field of medical science to devise a sleep pattern that best suits their number one star, to make sure he's in the best possible shape when he's behind the wheel.

Among the team tasked with making sure Hamilton gets the best night's sleep, are F1 fitness guru Dr. Aki Hintsa, and world leading neurologist and Harvard professor, Steven Lockley.
Between the two experts, a specific sleep routine is formulated with the aid of Hamilton's personal assistant, who provides all the travel information.

The routine is devised using the information of different time zones around the world, combined with Hamilton's flight times and lengths to produce the optimum sleep patterns to ensure the British racing icon does not suffer too much from the effects of jet-lag.
Hamilton's busy travel log is not filled solely with airport stamps that relate to the F1 calendar, however, he also added an extra seven countries to the list, in as many days, during a recent summer holiday.
In an interview featured in an article by The Sun, Hamilton said: "Usually jet-lag is never a problem. My body has probably never really known where it is.
"It's just getting on that time zone as soon as possible, and obviously keeping your body healthy so you don't get sick on those flights.
"I generally nap on all the flights but there are specific things you have to do which a specialist gives me through my trainer." He continued.
Medical and Sports Performance Director at Hintsa Performance Dr Luke Bennet was also interviewed for the article, and he said: "In transition to a new time zone there are a couple of things you can manipulate like exposure to light and darkness.
"On top of that, some drivers use a synthetic version of a natural hormone, melatonin. You need to time the new melatonin dose to help adjust to the new time of midnight."
