7. Excessive urination
Do you wake up several times a night to urinate? Waking up once or twice a night is normal. However, multiple times a night may signify a greater problem. It may be because of sleep apnea. This is not a symptom that you might naturally associate with sleep apnea. If fact, you are more likely to think this is related to having a small or active bladder. When oxygen decreases because of a lack of air flow, it signals to the body that something is wrong. This causes the body to release fluids, which in turn fills up your bladder. As a result, many sufferers of sleep apnea wake up several times a night to urinate. Getting unobstructed sleep can minimize or eliminate this problem.
