Why you might be waking up. Sleep architecture refers to the four stages of sleep people cycle through during the night in about 90 to 120-minute intervals, said Dr. Brandon Peters-Mathews, ...
After sustained periods of sleep, both the speed and synchronicity of the neurons firing are shown to decrease. [5] Another effect of wakefulness is the reduction of glycogen held in the astrocytes, which supply energy to the neurons. Studies have shown that one of sleep's underlying functions is to replenish this glycogen energy source. [6]
A study suggests non-genetic determinants of alertness upon waking up from sleep are: [25] [26] sleep quantity/quality the night before; physical activity the day prior; a carbohydrate-rich breakfast; a lower blood glucose response following breakfast (modifiable as well, for example via choice of food and with berberine [27])
The word hypnagogia is sometimes used in a restricted sense to refer to the onset of sleep, and contrasted with hypnopompia, Frederic Myers's term for waking up. [2] However, hypnagogia is also regularly employed in a more general sense that covers both falling asleep and waking up.
To sum up what both sleep docs have shared so far, waking up during the night is completely normal and not typically something to worry about. But both doctors say that if you can’t fall back ...

This problem arises because sleep was traditionally defined as a state of consciousness and not as a physiological state, [14] [15] thus there was no clear definition of what minimum set of events constitute sleep and distinguish it from other states of partial or no consciousness.
Waking up during this time can mean that you're backed up with "waste" in the form of negative emotions, and that you need to process them in order to flush them out.
Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
