Most people think poor sleep just makes them tired.
The truth is far more serious than that.
While you sleep, your brain is running its own cleanup crew — flushing out toxic waste, including the proteins linked to Alzheimer's disease. During deep sleep this system is up to 20 times more effective. Miss that window consistently and that toxic waste doesn't get cleared.
And the damage doesn't stop there.
— Just one week of reduced sleep can push blood sugar into pre-diabetic range
— Poor sleep drives up inflammation
— It weakens your immune system and raises cardiovascular risk
— It's directly linked to depression and anxiety
Every one of these conditions is also a driver of Alzheimer's disease. This is why sleep is not something you can afford to ignore.
If you think you can get by on five or six hours, or that you need less sleep as you get older, the research says otherwise. Seven to eight hours of quality sleep every night is not optional. It is one of the most important things you can do for your brain.
