Question

how do cells grow during sleep​

Answer 1

Many biological processes happen during sleep: The brain stores new information and gets rid of toxic waste. Nerve cells communicate and reorganize, which supports healthy brain function. The body repairs cells, restores energy, and releases molecules like hormones and proteins.

Answer 2

Explanation:

Sleep seems to wake up a type of brain cell that maintains healthy neuron signalling.

Sleep seems to wake up a type of brain cell that maintains healthy neuron signalling.Chiara Cirelli and her colleagues at the University of Wisconsin-Madison analysed support cells called oligodendrocytes that wrap around neurons and protect them with a specialized sheath that helps their signals to travel faster.

Genes that were most active during wakefulness were involved in cell differentiation and death. By contrast, genes that were expressed during sleep promoted cell growth and the production of protective sheaths.

Genes that were most active during wakefulness were involved in cell differentiation and death. By contrast, genes that were expressed during sleep promoted cell growth and the production of protective sheaths.Further experiments showed that the rate of growth of oligodendrocyte precursor cells doubles during sleep, and that cell production increased when mice spent more time in the stage of sleep associated with dreaming.
