Get enough sleep

Dopamine is a brain chemical that promotes feelings of alertness and wakefulness when it is released. According to research on animals, dopamine levels naturally decrease in the evening when it's time to go to bed and are naturally released in large amounts in the morning when it's time to wake up.

But it seems that sleep deprivation throws off these natural rhythms. The amount of dopamine receptors in the brain is significantly decreased in the morning after being forced to stay awake all night. Regularly getting good sleep might help keep your dopamine levels in check and make you feel more awake during the day. The National Sleep Foundation advises adults to get 7-9 hours of sleep each night and practice good sleep hygiene in order to maintain optimal health.
