A recent study out of Brazil shows that for people who suffer from sleep apnea, sleep may be easier to come by now than six months from now. This new research suggests that the symptoms of sleep apnea worsen in the colder months. The research team used data received from a sleep clinic in which 7,500 patients were observed over a 10 year period. Those people who sought treatment during the winter months had many more stops in their breathing during sleep than those who came in during the summertime. Although these patient’s symptoms were much worse in the winter than in the summer, the research team could not determine the reason for the difference. Research did not tie weather conditions directly to this effect. Lead researchers believe that the change in severity of symptoms could be due to common upper respiratory issues that commonly occur in the winter.
