OSA occurs when the throat muscles relax and obstruct the lungs’ ability to breathe while you’re asleep. People with the condition stop breathing multiple times per hour, causing symptoms including restless sleep, loud snoring, daytime sleepiness, and prolonged headaches in the morning.Studies show that 15-30% of men and 10- 15% of women have the condition- or 1 billion adults worldwide. However, it is estimated that 80% of people with OSA are unaware that they have it.In the current study, researchers studied a group of 27 men aged between 35 and 70 years old who had received a new diagnosis of mild to severe OSA without co-morbidities. They also included seven men as controls without OSA who were matched for age, BMI, and education.
