Hunger can be a cause of sleep disturbances, with some people reporting that they wake up in the middle of the night due to hunger. However, others have reported that they go to bed hungry but wake up feeling less hungry. This could be because the body goes into a kind of 'hibernation mode' when we sleep, and hunger pain is detrimental to sleep, so the body 'turns off' the pain until it needs to remind us to eat again. It could also be because sleep shuts down digestion, which takes a little time to start back up, and we have plenty of blood sugar to last us through the night.

What You'll Learn
Hunger can wake you up from sleep due to a rise in the hormone ghrelin
When you are hungry, your body goes into a bit of a hibernation mode when you sleep. Your body will check in to see if food is available. If it is not, it will turn off the feeling of hunger for a while until your body needs to remind you again.
However, if you are experiencing sleep deprivation, your body will produce more ghrelin, which will increase feelings of hunger. This can be a problem for people who are trying to maintain a stable weight, as increased ghrelin levels have been linked to weight gain and obesity.
To optimize your ghrelin levels, it is important to prioritize sleep and maintain a moderate weight. Eating more protein can also help reduce ghrelin levels and increase feelings of fullness.
