From The Irish Times...not The Onion:

GOLF: GOLFERS WITH the night-time breathing disorder obstructive sleep apnea can improve their game and cut their handicap by up to three strokes by treating their sleeping problem, according to a small US study.

Researchers found that golfers could reduce their handicap after a few months of using a night-time device that provides nasal positive airway pressure (NPAP) – a treatment that has been shown effective for curbing sleep apnea.

The study was based on 24 golfers and saw their average handicap fall significantly from 12.4 to 11.0. The effect was even more pronounced in better golfers with a handicap of 12 or under whose average handicap dropped from 9.2 to 6.3.

“The surprise was that the most significant improvement was noted in the lower handicap golfers, many of whom were older,” researcher Dr Marc Benton said.

Benton estimated that there are one to three million regular golfers in the United States who suffer from sleep apnea, and most are undiagnosed or untreated.

Obstructive sleep apnea is a disorder in which the tissues at the back of the throat temporarily collapse during sleep, causing repeated stops and starts in breathing during the night. This leads to poor-quality sleep and, often, daytime drowsiness, fatigue, and cognitive impairment.

I'm guessing this isn't on the PGA Tour's banned list?
