3 reasons you keep waking up in the middle of the night
1. Stress or anxiety: You may notice a change in your food habits, a decrease in the amount of natural light you get, a decrease in your exercise
routine, or a reduction in your social interactions. Your sleep/wake cycle is affected by all of these factors, thus stress is indirectly affecting how well you sleep.
2. Bad sleep hygiene: You could attempt to go to bed early every night or stay up later than you should. It's possible that you don't have a set
bedtime. Alternatively, you manage to get to bed on time, but spend the next hour or two gazing at blue light emanating from your phone's screen.
3. An underlying medical problem: You may occasionally wake up in the middle of the night or early in the morning due
to an underlying medical condition. These can include low blood sugar, GERD, sleep apnea, depression, and reflux.
