14. Sleep Apnea
If you go to bed and still wake up tired, you could have sleep apnea. This interruption in your sleeping pattern can happen because your brain is not receiving enough oxygen. Your sleep could be interrupted as often as 100 times a night, so you feel extremely tired in the morning even if you believe you’ve slept for hours. Your brain senses that you’re not breathing and will send signals to wake you from sleep so that you can start breathing properly again.
There are two kinds of sleep apnea, OSA and CSA. OSA is obstructive sleep apnea and results from your muscles relaxing too much and causing an obstruction in your throat that prevents enough air from getting to your lungs. CSA is central sleep apnea, where your brain isn’t telling your body to keep breathing when you’re asleep. Both are extremely serious conditions that interfere with your natural sleep stages and leave you feeling very exhausted the next day.
