We celebrate the hustle. It is a badge of honor to burn the midnight oil. But what should come with that terrifying price be that badge? A shocking reality is now emerging through a revolutionary research. The sleepless nights are creating active brain rewiring that is speeding up a route into mental decay. It is not merely about feeling misty. It is about the nocturnal accretion of the toxins that are directly associated with the Alzheimer disease.
Your Brain’s Night Shift
And as you sleep, you brain is anything but slumberless. It initiates a vital intense cleaning procedure. This is referred to as the glymphatic system. Imagine it to be a small janitorial crew on the night shift. Your brain cells even shrink during a deep sleep. This opens up avenues and the cerebral spinal fluid cleanses the metabolic waste of the day.
Beta -amyloid is the most hazardous part of this waste. This proteinaceous substance forms plaques. These are the plaques that characterize the Alzheimer disease. This was proved in a study by Nature. They discovered the glymphatic system of clearance of amyloid is astoundingly effective in sleep. In simple words, sleep is power washing of your brain.
The Slow Drip of Sleep Debt
That may seem to apply only to severe insomniacs. You would be wrong. Chronic and mild sleep loss is the actual threat. Your daily habit of only getting 90 minutes of sleep below what you require produces a shortage. The effect of this slow drip of sleep debt is tremendous.
Consider a 2021 study from Aging. Scientists monitored elderly people with mild impairments. They employed sleep monitors and PET. The results were stark. Patients that had less efficient sleep had much higher amyloid burden. Their brains were even younger than their age. This was not a case of a bad night. It was the pattern.
Dr. Rebecca Robbins, Sleep Researcher: “Well, have you got six hours?”. Now we know that’s not enough. The objective is quality and quantity. The lack of one or the other means we are neglecting our brain maintenance.
A Vicious Neurological Cycle
Whether or not there is a cause and effect of sleep and Alzheimer is a two-way street. It generates a scary self-perpetuating cycle. Sleep disorder results in an increase in amyloid. Then this amyloid especially in some parts of the brain destroys the very sleep centers to which you require. Your capacity to have a deep, restful sleep reduces.
As a result, the cleaning mechanism in the brain is even impaired. This enables the accumulation of more plaques. The cycle feeds itself. This could be the reason why one of the very first clinical manifestations of Alzheimer is sleep disturbances. They are manifested several years, in some cases even decades before the loss of memory is evident.
A Personal Wake-Up Call
I remember one patient, a brilliant 52 year old engineer called David. His five-hour nights were a point of pride with him. He had approached me with the issue of concentration. Mild problems were demonstrated in a cognitive test. We discussed his sleep. He regarded it as a price to success. I gave an explanation to the amyloid research. His turning point was the idea that his effort to work might be damaging his brain in the future. Tiredness was no longer about being tired. It was concerning the saving of his mind.
Beyond the Lab: a social experiment
The lab data is alarming. But the consequences are felt out there in the world. Consider the increasing rate of mental problems in high stress, sleep deprived careers. According to a recent report, there were more early-onset cognitive issues in the tech sector. All-night coding sessions are glorified in this industry.
The biology of our brain is incompatible with the modern world. Pale light on screens inhibits melatonin. We are always connected, and this makes our minds go. We have made an atmosphere that progressively takes away the deep sleep. It is an uncontrolled experiment on our compound neurological health.
Case in Point: A 25-year longitudinal study conducted in the Journal of the American Medical Association involved almost 8,000 individuals. The individuals who had been constantly reporting the short duration of sleep in their 50s and 60s were found to have a 30 percent increase in the risk of dementia in old age.
Turning the tide: Hope on the horizon
It is not doom and gloom in the news. This research empowers us. One of the risk factors that can be modified is sleep. It is something that we are in direct control over unlike genetics. Researchers are currently conducting a test of whether the ability to slow down cognitive deterioration is possible through the enhancement of sleep. Initial CBT-I (Cognitive Behavioral Therapy in Insomnia):Initial results are encouraging. They are not only raising the sleep scores. They are also enhancing mental indices.
Consider sleep as one of your investments of in the brain per night. It is an uncompromising investment in your future. Sleeping is no longer a mark of laziness. It is the final measure of health conservation in the long run.
Your Action Plan
Start small. Treat your sleep as it is a valuable property.
- Set a digital curfew. Switch-off gadgets 60 minutes before sleep.
- Create a cool, dark cave. Bedroom should be optimalized to sleep.
- Be consistent. Get up at the same time including on weekends.
A Final, Uncomfortable Truth
The I will sleep when I die attitude should be dumped by all. That is a mantra that is starting to be a dangerous self-fulfilling prophecy. It is a venture that is bankrupting our intellectual futures on the quest of productivity. It is no longer whether sleep can be of benefit to the health of the brain. The science is unequivocal. The question then arises, what we as individuals and as a society are going to do about it? It is possible that the most significant prescription of preventing Alzheimer disease is not lying in a pill bottle. It is in the mere, bold gesture of switching off the lights.
