Why Deep Sleep and REM Sleep Are Crucial for Brain Health
Briefly

Quality sleep significantly impacts brain health and could reduce the risk of dementia. Disturbed sleep, such as insomnia or sleep apnea, has been linked to higher dementia risk. Studies indicate that individuals in their 30s and 40s with disrupted sleep patterns are more likely to experience cognitive decline. Notably, deep sleep and REM stages are vital for brain recovery, memory consolidation, and waste clearance. Ongoing research suggests deficiencies in these sleep phases may lead to early signs of Alzheimer's, underscoring the importance of maintaining good sleep quality.
A good night's sleep isn't just about the number of hours you log. Getting quality sleep the kind that leaves you feeling refreshed is critical for a healthy brain.
Deep sleep and rapid eye movement (REM) sleep are particularly influential when it comes to brain health and dementia risk.
