Could Healthy Habits Actually Clean Your Brain While You Sleep?
Recent research shows that during deep non-REM sleep, your brain stays partly active and removes waste through the glymphatic system. This system, which depends on brain cells called glial cells, helps clear waste and toxins, including proteins that, for example, can build up and are associated with Alzheimer’s disease.
As reported in Nature Communications and highlighted by Economic Times (2025), lifestyle habits can support this cleaning process and improve brain health.
All of the following habits can boost your brain’s nightly cleaning.
Which one do you find hardest to maintain?
Keeping a regular sleep schedule
Getting morning sunlight
Exercising regularly
Drinking enough water
Avoiding heavy meals before bed
Avoiding caffeine, nicotine, and alcohol before bed
