Poor sleep has been linked to an increased risk of developing Alzheimer’s disease. Aim for 7-8 hours of sleep each night.
Sleep is the act of resting the body and mind, usually for several hours at night, during which the brain undergoes various processes that are essential for its health and function. Sleep can provide many benefits for our brain health, such as:
Consolidating and enhancing memory and learning
Clearing out toxins and waste products from the brain
Regulating mood and emotional well-being
Restoring energy and metabolism
Strengthening the immune system and fighting infections
These benefits may also help protect the brain from the damage caused by Alzheimer’s disease. According to some studies, people who get enough quality sleep have a lower risk of developing Alzheimer’s or a related dementia than those who suffer from sleep deprivation or poor sleep quality . The exact mechanism of how sleep prevents or delays Alzheimer’s is not fully understood, but some possible explanations are:
Sleep facilitates the removal of amyloid beta, a protein that accumulates in the brain and forms amyloid plaques, which are the hallmarks of Alzheimer’s disease.
Sleep enhances the production of cerebrospinal fluid, a fluid that circulates in the brain and spinal cord and helps flush out harmful substances from the brain.
Sleep boosts the activity of glymphatic system, a network of vessels that drains waste products from the brain and transports them to the lymphatic system.
Sleep improves the function of microglia, a type of immune cells that patrol the brain and eliminate pathogens, debris, and damaged cells.
Therefore, getting quality sleep may be a simple and effective way to prevent or delay Alzheimer’s disease. There are many ways to improve your sleep quality, such as:
Following a regular sleep schedule and sticking to it
Avoiding caffeine, alcohol, nicotine, and heavy meals before bedtime
Creating a comfortable and quiet sleeping environment
Limiting screen time and exposure to blue light at night
Practicing relaxation techniques or meditation before bed
The key is to find a sleep routine that works for you and your lifestyle. You can also combine sleep with other healthy habits, such as physical exercise, mental activity, or social interaction, to maximize your brain health and well-being.
