why is sleep so important for mental health?
higher gaba levels calm the brain down, easing anxiety
oxytocin is released during sleep
it is now easier to remember things
higher dopamine levels increases happiness

Explanation:

GABA (gamma - aminobutyric acid) is an inhibitory neurotransmitter. During sleep, GABA levels increase. This helps in reducing the excitability of neurons in the brain, which in turn calms the brain and eases anxiety. Oxytocin is mainly associated with social bonding and is not the key factor related to sleep's importance for mental health in the context of this question. While sleep does aid in memory consolidation (which is related to remembering things), the question is about mental health in terms of calming the brain. Dopamine levels are more related to the reward system and are not the main factor that directly explains why sleep is important for mental health in the way this question is framed.

Answer:

Higher GABA levels calm the brain down, easing anxiety.
