It is a known fact that about 25% of men and women above 45 suffer from serious snoring and sleep apnea. At that, about 3% of those experience gasping and numerous interruptions in breathing, which eventually lead to constant sleep interruption at night. Recently, a group of British specialists carried out a series of researches, which ended up with some disappointing findings. They registered new scientific evidence of the fact that snoring affects our brain activity and increases the risks of having a stroke.
The sleep of 13 volunteers (12 male and 1 female) with heavy forms of snoring (obstructive apnea) was under close observation of the scientists. It was found out that there are certain bio-chemical changes that occur in the brain under effect of snoring. Most likely, the brain is affected by a lack of oxygen caused even by a short interruption of breathing, which occurs in people with sleep apnea. Negative effect of such interruptions in breathing is very strong, that is why the specialists suggest to revise our attitude toward snoring and not to delay treatment of this ailment.
Moreover, obstructive apnea and hypopnea proved to cause decreased blood flow to brain, as well as create extra pressure on the chest and heart. The scientists say that every night the people with obstructive apnea have to fight for breathing with the same efforts as the ones they would have to spend for breathing with a hand over their nose and mouth. According to Dr. Kingman P. Strohl of Case Western Reserve University, reduced blood flow to the brain caused by severe snoring increases risks for stroke.
