FLORHAM PARK, N.J. -- The New York Jets met with a sleep therapist to find ways to adjust to the five-hour London time change.
One rookie took the expert's advice to heart immediately.
First-round pick Leonard Williams admitted to dozing off in the Monday meeting not long after the therapist turned off the lights in the meeting room. Although he says the therapist said sleeping was allowed.
"I was kind of nodding off," Williams admitted with a laugh. "The guy was telling us it is alright to go to sleep. He shouldn't have said that. He turned off the lights. I was trying to pay attention."
Head coach Todd Bowles probably didn't mind since it wasn't in a positional or football team meeting and because he wants his players as fresh and rested as possible for Sunday's international divisional showdown with Miami.
In fact, Bowles is leaving nothing to risk when it comes to his team adapting to this challenging road trip.
In each player's locker stall was a new addition this week -- a set of orange eyeglasses. The glasses -- which look similar to safety glasses people sometimes wear at a gun range -- are "light-blocking" glasses designed to help players for late-night studying on tablets, laptops and phones.
So before they play the Dolphins, several Jets players could already be seeing a lot of orange each night before sleeping.
"It is supposed to block out the blue light which causes you to stay awake a lot at night," offensive lineman D'Brickashaw Ferguson explained. "A lot of our iPads, iPhones, Androids, I guess it emits a certain light. It messes you up when you are trying to go get rest (after). It is not just the light."
There are plenty of things that can unintentionally keep players from getting the necessary rest needed on this trip. Caffeine after a certain hour during the day and large meals less than three hours before bedtime will be discouraged.
The players also have been equipped with a "Litebook" which provides bright light to give players enough light for at least an hour upon waking up on Saturday and Sunday. The thinking is that the body's internal clock can acclimate better with natural sunlight or light from the Litebook in the morning.
"I think a lot of (these) things are odd because you don't do it on a normal basis," Ferguson said of all these things the Jets will try this week. "You don't normally wear blue blockers or have (artificial) sunlight while you are eating breakfast. Those are things that you don't normally do. But we don't normally play in London."
"I have gone to London, not for sports, but you do feel the difference," Ferguson added. "If you don't handle it right, you can be a little jet-lagged for a couple of days."
This will be Darrelle Revis' first trip to London and he says he will follow the advice given to the team such as getting five hours of sleep on the flight to London on Thursday night even if it means going to bed earlier than normal. The team, which is also bringing its chef on the trip, will land in the morning over in London.
"It is going to be tough," Revis said. "We are trying to treat this like we are going to a West Coast game but we are actually going the opposite. ... We listen to try to do every step and everything the right way."
Williams was listening to the sleep therapist too. Perhaps too well.
"The main thing I got out of it is he said we should try to go to sleep a little earlier and wake up a little earlier than we have been," said Williams, whom coaches have praised this season for being a quick learner in the classroom.
"He turned off the lights," Williams added of dozing off again. "I think he did it on purpose, to be honest, because he had a few things where people had to raise their hands. He was like, 'The only people not raising their hands are the people asleep.'"
Bowles will probably be fine with players catching a few Zzzz's this past Monday as long as it leads to a 'W' on Sunday in London.
