9. Night sweats
At first glance, night sweats may seem completely unrelated to sleep apnea. You may just think it is hot in your room or that your body heats up while you sleep. Night sweats make you uncomfortable and disturb your sleep. Your body temperature is controlled by the endocrine system. When that system is disturbed by sleep apnea, it causes your body to release sweat. Therefore, sweating during nighttime is a manifestation of sleep apnea.
