Sunglasses Help Ease Jet Lag

Tuesday, 11 April 2006 12:00 AM

If you are taking a long-distance jet flight, it may be a good idea to wear sunglasses, at least for part of the flight, according to a new study from Scotland.

Sleep specialists in Edinburgh have found that wearing sunglasses reduces the time it takes to recover from jet lag. Altering light patterns somehow enables the body clock to readjust more quickly, they explain.

Dr Chris Idzikowski and his colleagues at the Edinburgh Sleep Centre monitored jet lag in more than 1,000 airline passengers.

They found that when people flew west, from New York to Britain, a 5 hour time zone change, it took 5 days to recover.

But flying eastward, the recovery took 7 days.

"When passengers are traveling west it's like a long day for the biological clock but when flying east, the clock tries to go into reverse which is obviously harder," Dr. Idzikowski said.

However, wearing shades for part of the trip can take days off the recovery time, he said.

He advises travelers to wear sunglasses during the last couple of hours of an overnight flight, and then for two hours once on the ground.

"I have used this technique on a flight but you have to be aware of immigration officials as they can ask you to take them off, which weakens the outcome."
