How Sleep “Cleans” Your Brain
Dr. Carl Boethel, with Baylor Scott & White, explains that sleep is more than just rest — it’s when the brain conducts vital maintenance.
“During sleep, we’ve found that’s when the brain runs its cleaning system. It’s like having a lymphatic system in the brain that washes away toxins and proteins. Without good, efficient sleep, these proteins — which can be linked to dementia — aren’t cleared out,” Boethel says.Anxiety is one of the most common triggers of insomnia, with depression also playing a role. Stressing in bed and failing to relax can lead to poor sleep efficiency and ongoing sleep deprivation — conditions that researchers believe contribute to dementia risk.
Why Sleeping Pills Aren’t the Answer
For those battling insomnia, Boethel offers clear advice:
“If you are struggling with insomnia, talk to your doctor. We don’t recommend sleeping pills anymore, because many medications once used to treat insomnia now appear to cause more harm than good.”Instead, doctors advise behavioral strategies that encourage consistent, quality rest.
Better Sleep Habits to Protect Your Health
Experts recommend adopting regular routines and avoiding habits that disrupt sleep:
- Go to bed at the same time every night
- Sleep in the same bedroom — keep it dark and cool
- Avoid alcohol and caffeine before bedtime
- Quit smoking or vaping nicotine products
- Limit screen time before bed to help your mind relax
Quality sleep isn’t just about feeling rested — it could be key to protecting your brain and reducing long-term risks like dementia.
