Sleep, workout and 25 ml of wine each day can help the brain to’ washing’ itself and wipe away toxic proteins linked to Alzheimer’s, scientists claim

Sleep, exercising and a little alcohol can help the brain awasha itself at night to prevent Alzheimeras, scientists say.

British researchers detected the combination stimulated the brainas own clean system, wiping away the toxic build up of proteins linked to the devastating disease.

The research on mice is a breakthrough as it could now be used to create new insights into how the human brain runs a and clears away its waste products.

Dr Ian Harrison, from University College London, told the Cheltenham Science Festival surveys on the brain liquid of mice showed that a good nightas sleep, increasing heart rate through workout, and 25 ml of wine per day stimulates the brainas own cleaning system.

Scientists observed brain fluid, which is key to transporting trash out of the brain, penetrated deeper into the organ during sleep, constructing the body’s self-cleaning process more effective.

Research is now focusing on finding ways of preventing the human brainas cleaning system a the glymphatic system a from failing.

Dr Harrison told: aA newspaper “re coming out” a couple of years ago where the researchers studied the brains of mice when they are asleep and mice when they are awake.

aWhat the researchers did was inject a dye into the cerebrospinal[ brain] liquid and assure where it goes.

aIn the mouse that were awake, that cerebrospinal liquid starts to go into the brain but merely resides on the surface and doesnat go deep into the brain tissue.

aIn the same animal when it fell asleep, that cerebrospinal liquid goes far deeper into the brain.’

The cerebrospinal liquid is known to transport waste material out of the brain, and the body’s cleaning system works better when the fluid reaches deeper into the brain.


Alzheimer’s disease is a progressive, degenerative illnes of the brain, in which build-up of abnormal proteins causes nerve cells to die.

This interrupts the transmitters that carry messages, and causes the brain to shrink.

More than 5 million people suffer from the disease in the US, where it is the 6th leading cause of death.


As brain cells die, the functions they offer are lost.

That includes memory, orientation and the ability to think and reason.

The progress of the disease is slacken and gradual.

On average, patients live five to seven years after diagnosis, but some may live for ten to 15 years.


Loss of short-term memory
Behavioral changes
Mood swings
Difficulty dealing with money or making a phone call


Severe memory loss, forgetting close family members, familiar objects or places
Becoming anxious and frustrated over inability to make sense of the world, leading to aggressive behavior
Eventually lose ability to walk
May have problems eating
The majority will eventually need 24 -hour care

Alzheimer’s disease, which is the leading cause of dementia and constructs the brain degenerate, is caused by a build up of toxic clumps of proteins which damage healthy brain cells.

In people without the disease, the body rids itself of the proteins.

‘In the animals that were asleep, this glymphatic system was far more active- 60 per cent more active than in the animals that were awake ,’ Dr Harrison continued.

aThis is good evidence that the glymphatic system is active during sleep. If that is anything to go by we should all be sleeping a lot more than we are.

aThat kind of builds sense because, if you think about it, when your brain is active during the day these brain cells are going to be actively producing all these waste products.

‘So it is only at night when our brain switches off that it has the chance to switch on our glymphatic system and get rid of all these waste products.a

Dr Harrison said there were comparable results with exercising, adding: aIn the sedentary animals, the cerebrospinal liquid penetrates the brain.

‘But when the animals have voluntary access to exercise there is a massive increased number of the amount of glymphatic function.a

It is thought the increase in heart rate assistances drive the cerebrospinal liquid into the brain.

The scientists also treated mouse with low-level, intermediate and high-level dosages of alcohol for 30 days.

Dr Harrison used to say low-level dosages of alcohol a the equivalent of a third of a unit a day in a human a resulted in a 30 per cent to 40 per cent increased number of the brainas self-cleaning.

But intermediate or high-levels of alcohol have the opposite effect.

He told: aSo 25 ml of wine was likely to increase your glymphatic system, according to this mouse study.a

Dr Harrison added: aSo, sleep more, exercise and, as the data indicates, you can have a drink, but merely a third of a division of wine per day.a
