If you find yourself wondering why you wake up early for no reason, there could be something your body is trying to tell you, according to Bustle.

While super early morning awakenings are totally normal from time to time, if you find that they happen a lot, or with increasing frequency, it might be a sign that your body is trying to tell you something. Verywell Health suggests that there can be a number of reasons why you’re waking up too early every morning, and there may be either physical or mental health issues at play. Racing thoughts, dwelling on worries, and stressing about the demands of the day ahead can all contribute to “sleep maintenance insomnia”, according to Harvard Health, which is a specific type of sleep disorder in which you can fall asleep, but have trouble staying asleep.

A common feature of the disorder is waking up too early without being able to doze off again, and it tends to affect women more often than men — especially as life gets increasingly complex as we get older. Verywell Health also notes that certain brain chemicals that regulate our circadian rhythms and encourage deep sleep, start to decrease in the wee hours of the morning, which is why early morning awakenings associated with sleep maintenance insomnia can be a little tricky to resolve.
