Think 8 hours of sleep is the best for your cognitive health? A new study suggests otherwise

A recent study from Edith Cowan University in Western Australia challenges the conventional wisdom that 8 hours of sleep is ideal for cognitive health. The research published in Alzheimer’s & Dementia indicates that sleep habits may significantly affect the risk of Alzheimer’s disease by influencing brain structure and cognitive performance through genetic factors related to fluid movement in the brain. This finding suggests that understanding and optimizing sleep patterns could be crucial in preventing neurodegenerative diseases, highlighting the complex relationship between sleep and brain health.
