Psychology Today: Uable “brainwashing” if not sleeping enough
Psychology Today: Uable “brainwashing” if not sleeping enough. A new study shows that through high-quality sleep, toxic wastes from the brain can be washed away, helping to cure mild traumatic brain injury (mTBI).
When it comes to “brainwashing”, everyone usually thinks it is evil. But in fact, we are “brainwashed” almost every night, but this “brainwashing” is not the other “brainwashing”. Not only is it not a bad thing, it can also help keep the brain healthy.
Recently, the American mental health website Psychology Today (Psychology Today) integrated the latest research, introduced a kind of “brainwashing” phenomenon that occurs naturally during sleep.
“Brainwashing” while sleeping can remove toxic debris
On October 31, 2019, the Boston University research news website The Brink published an article “Are We “Brainwashed” in Sleep?” “The article stated that a Boston University study revealed “the first ever image of cerebrospinal fluid washing in and out of the brain during sleep.” The research was published in the journal Science on the same day.
Scientists found that during sleep, the brain showed blood oxygenation waves (red), followed by cerebrospinal fluid waves (blue)
Studies have shown that the neurons of the human body will calm down while sleeping. After a few seconds, blood will flow out of the brain. Then, a fluid called cerebrospinal fluid (CSF) will flood into the brain and emit a rhythmic, impulsive wave. Way to flush the brain.
Earlier studies have shown that both cerebrospinal fluid flow and slow-wave activity help flush out toxic, memory-damaging proteins from the brain. As people grow older, their brains usually produce fewer slow waves. In turn, this may affect the blood flow of the brain and reduce the pulsation of cerebrospinal fluid during sleep, leading to the accumulation of toxic proteins and the decline of memory ability.
Good sleep can help heal traumatic brain injury
Another study published in the Journal of Neurotrauma in February 2021 showed that high-quality sleep can wash away the toxic wastes of the brain, which plays a role in curing mild traumatic brain injury (mTBI) critical use.
In this study, researchers at Oregon Health and Science University (OHSU) studied 56 U.S. veterans who had experienced mTBI related to military explosions in Iraq or Afghanistan. They used a new technique called magnetic resonance imaging (MRI) to assess the size of the perivascular space (PVS) surrounding the blood vessels of the brain, which is part of the brain’s so-called “waste removal system.”
“Imagine your brain is producing waste, and everything is working well. Now you have a concussion, the brain produces more waste, which must be removed, but the system is blocked, and we can measure this structure very accurately and Calculate the number, location and diameter of the channels.” Research author Juan Piantino said in a news published on the school’s official website on March 12.
Studies have found that people with poor sleep have greater PVS and more severe symptoms after a concussion. The expansion of PVS usually occurs in the process of aging and is related to the development of dementia.
Piantino pointed out that this discovery has a significant impact on the armed forces and civilians. Studies have shown that sleep may play an important role in removing waste from the brain after a traumatic brain injury. In other words, if you do not sleep well, you may not be able to effectively clean the brain.
These studies tell us that it is important to avoid staying up late and improve sleep quality through a variety of methods. In the long run, “we can start to consider using this neuroimaging method to predict who is at higher risk of facing cognitive problems including dementia,” Piantino said.
