Do sleep disorders affect women differently?
Again, one of the curiosities with sleep disorders is, and in the early days of sleep disorder work, it was often the case that women seemed to complain more about sleep problems. But when they were brought into the center, they wouldn't have them. Whereas men wouldn't complain, but when they were brought in for sleepiness, they would have these respiratory sleep disorders. So in fact, there is this big difference between respiratory sleep disorders across the two sexes. Men tend to be more overweight, and end up suffering from sleep apnoea. It's happening more with women. Also, women with progesterone, their hormone progesterone, that seems to protect them from sleep apnoea until the menopause. So it ends up with respiratory sleep disorders, men being dominant in that. Also, for reasons that are clear, REM behavior disorder is a condition which is still male dominant. I don't have any idea why that's the case. As far as women are concerned, we're talking about tiredness and fatigue and insomnia being the bigger problem. So there is a sex difference there.
