Here’s some bad news for chronic snorers who love to play the game of golf. According to a recent study, eliminating chronic snoring can improve the handicaps of golfers.

A study conducted by researchers at the Morristown Memorial Hospital tested a several golfers who are suffering from severe sleep apnea — a disease that restricts oxygen flow through the mouth and nose and causes the sufferer to stop breathing for more than ten seconds at a time.

During the experiment, 12 golfers were asked to use a device at night to ease breathing, while another 12 were tested without treatment. Throughout the experiment, levels of sleepiness were assessed before, during and after 20 rounds of golf.

The findings showed that golfers who had received treatment saw their average handicap fall significantly from 12.4 to 11.0, while lower handicapped golfers recorded an ever further drop from 9.2 to 6.3.
