Just as deep sleep renews the body, REM sleep renews the mind by playing a key role in learning and memory. During REM sleep, your brain consolidates and processes the information you’ve learned during the day, forms neural connections that strengthen memory, and replenishes its supply of neurotransmitters, including feel-good chemicals like serotonin and dopamine that boost your mood during the day.
To get more mind and mood-boosting REM sleep, try sleeping an extra 30 minutes to an hour in the morning, when REM sleep stages are longer. Improving your overall sleep will also increase your REM sleep. If you aren’t getting enough deep sleep, your body will try to make that up first, at the expense of REM sleep.
Lack of REM sleep past two days might have an effect of my mood lately. Hope to get the sleeping schedule fixed up right again.
Currently have a lot of on my todo-list. Hope to complete it all. Make a promise to yourself that you can keep.
