Sleep Apnea
Sleep apnea [1] is a condition where your breathing stops and starts while you sleep. Some symptoms of this include dry mouth, headache, sore throat, lightheadedness, irritation. The condition shares similar symptoms with common cold and the flu, therefore, this makes it hard to detect through symptoms alone. Doctors sometimes have to recommend sleep studies where your sleep will be monitored. Records of your breathing, heart rate, oxygen levels, and brain activity will be taken for analysis. Sleep apnea is a serious sleeping disorder that should be treated as soon as discovered.
