Your lack of sleep is making you sick

How’d you sleep last night? Did you get a peaceful eight hours or were you tossing and turning? Do you have sleep problems on a regular basis? If you answered yes to any of these questions, then your brain is at risk of developing Alzheimer’s disease, according to research findings.

Alzheimer’s disease affects over 44 million people worldwide and as the world’s population continues to age, this number is expected to grow.


On the other hand, nearly two-thirds of Americans do not get a restful eight hours of sleep, which experts are referring to as “the silent sleep loss epidemic.

It is known that poor sleep is linked with poor health, and now poor sleep has been connected to mental decline too.

Sleep expert Matthew Walker has heavily explored the link between sleep and Alzheimer’s disease and suggests that lack of sleep leads to a build-up of toxic proteins in the brain. These can contribute to Alzheimer’s disease, a weaker immune system, and activates stress chemistry, which leads to poor cardiovascular health.

Although many of us think that taking a mid-day nap to make up for our poor sleep is good, Walker suggests that naps aren’t the solution and are really a double-edge sword. He explained, “You can’t accumulate a debt and then pay it off either by napping or over-sleeping at the weekend. It’s an all or nothing event.

There have been some studies suggesting that naps can offer benefits, but Walker explained that naps should be regular and occur prior to 3 pm.


Walker also spoke largely against sleep pills, which do not produce a “naturalistic sleep.” “They’re a class of drugs that we call the sedative hypnotics and sedation is not sleep, so you’re simply removing consciousness,” he added.

Tips to improve sleep

Walker did offer up suggestions to help you improve sleep in order to protect your memories along with overall health. They include:

  • Go to bed and wake up at the same time daily
  • Dim your lights at night and limit screen time (phones, computers, tablets, and TV)
  • Keep your bedroom at a cool temperature
  • Don’t stay awake in bed
  • Avoid drinking coffee or any caffeinated item after 2 pm and avoid alcohol

If you are still struggling to get a good night’s rest after these suggestions, you should speak to your doctor about any underlying health issues that could be keeping you up at night.
