Why Sleep Is Essential for Your Brain
We often think of sleep as a passive state- a time when the body and mind simply relax or “shut down.” But as a neuropsychologist, I can tell you that sleep is one of the most active and vital processes for your brain health and brain aging. This is particularly important when thinking about cognition.
What Happens in the Brain During Sleep?
Memories are consolidated with what you learn throughout the day being transferred into long-term storage.
Toxins are cleared as your brain has a “clean-up system” (the glymphatic system) that clears out waste that builds up during waking hours.
Neural pathways in your brain are strengthened for things such as attention, problem solving, and emotional regulation.
Sleeping poorly or sleeping too little disrupts these processes and that disruption often time shows up in your daily cognition.
Consistent sleep deprivation also has long-term consequences and can be associated with:
Increased risk of cognitive decline, including Alzheimer’s Disease
Increased vulnerability to depression and anxiety
Negative effects on areas of physical health such as weakening your immune system, increased risk for heart disease, obesity, hormonal dysfunction.
If you are experiencing persistent sleep issues its worth discussing with your doctor to receive guidance on safely and effectively tackling your sleep problems.
