Those who sleep in this way are more likely to have problems!Don't sleep enough

Suffering and good sleep have an irreplaceable effect on maintaining brain health.Many studies have already beenInsufficient sleep and brain disease,hot topic In particular, the risk of neurotic diseases such as dementia is risky.

In the state of healthy sleep, the brain has the opportunity to "work" such as memory consolidation, information integration, neuron repair, eliminating metabolic waste accumulated during the day, etc.Effectively reduce the decline in cognitive function, emotional fluctuations, and risk of various brain diseasesEssence

That healthy sleepDo you just have enough sleep?The answer is not, healthy sleep includes not only sufficient sleep time, but alsoRegularity of sleepThat is to sleep and awaken time, sleep and wake up at the same time every day.If sleep is irregular, it will also harm brain health.

According to a study published in the journal "Neurology" published in the American Neurology Society, it is found that, it is found that, it is found that it is found.People with irregular sleep are more likely to have dementia.

Researchers from institutions such as Monash University, Australia, analyzed data in the UK BIOBANK (UK BIOBANK) data, and were incorporated into8809440-69-year-old participants.Participants average62 years old56%are women.

Through the questionnaire, the researchers counted the height, weight, education level, etc. of the participantsBasic Information; Smoking status, amount of exercise, working hours (white class or night shift) and working status (job or retirement), etc.Life and work information; Depression, hypertension and diabetesHistory and treatment history of patients with chronic diseases;DementiaFamily historyInformation; and lipoprotein E (APOE) ε4Gene mutationInformation and other information.

By wearing monitoring instruments for 7 consecutive days (1 week), researchers collected the participantsSleep data, Such as sleeping time, awakening time, etc., and use the sleep rules index (SRI) to calculate theirRegularityThat is, the consistency of the daily sleep-awakening mode.The total score of the rules of sleep is 100 points,The higher the scoring score, the more regular sleep isEssence

In addition, the researchers also evaluated the participants through MRI (MRI)Brain health related logoThe level, including the total brain volume (TBV), hippocampus volume (HPV), total gray quality (GMV), total white mass volume (WMV), and white -quality high signal volume (WMHV).

Statistics show that the median score of all participants' sleep rules is60 pointsEssenceDuring the 7.2 -year follow -up period, a total of new dementia480 casesEssence

After the impact of other factors, the researchers found thatIrregular sleep is related to the risk of dementia in participantsEssence

Compared to the sleep rules index score60 pointsParticipants,5%of the participants with the lowest score(Average 41 points), that is, 5%of the most irregular sleeping participants,The risk of dementia increases 53%Essence

In addition, the study also found that compared to the 60 -point participants from the sleep rules index,The lowest 5%of the participants, the total gray matter volume and the size of the hippocampus are lowerEssence

Gray quality is the nerve tissue in the brain, including the cell body, dendritic and other parts of the nerve cells.It is a key area for information processing and integrationIt plays a key role in human information processing, sensory and exercise control, memory and learning.The decrease in gray quality may endanger brain health.As a result, the cognitive function decreasesIncrease the risk of mental illness, and problems with exercise and sensory control.

Haima body is responsibleMemory and learning functionThe important brain structure plays an important role in the integration and storage of information in long -term memory, space memory, information in the process of learning, and emotional regulation.The reduction or damage of the hippocampus may causeMemory disorders, Space -oriented issues, difficulties in learning.

Researcher analysis,Risk of irregular sleep and dementiaThe association may be related to various factors.

Irregular sleep mayAffects sleep-awakening cycle, leading to biological clock disorder, By increase the risk of cardiovascular disease and cardiac metabolic diseases, they are all risk factor for dementia.

The rhythm of day and night is closely related to the secretion of multiple hormones, including cortisol, growth hormone and thyroid hormones.The disordered biological clock mayAs a result, these hormones are unbalanced, Then affect the function of the brain and overall health.

The rhythm changes of day and night possibilityAffects the release and regulation of neurotransmitters in the brain, Such as tormeal glands, dopamine, and glutamic acid, which affects awakening, cognition and emotions.

Normal day and night rhythm helps cells to repair and clean up, especially in deep sleep.Biological clock disorders may cause this process to be blocked,Increase the accumulation of harmful metabolites in the brainEssence

also,Irregular sleep is also a sign of unhealthy lifestyleIncluding lack of sleep and exercise, this will also increase the risk of dementia.

butThe relevant mechanism is not clear yetAnd more research and exploration.

have to be aware of is,This study is observation research, but it only shows that there is a connection between irregular sleep and the risk of dementia. It does not indicate the cause and effectEssenceAnd there are some limitations of research. If the impact of sleep disorders is not considered, it may also have an impact on the results of the research.

Study finally pointed out,Maintaining cognitive function is an important part of healthy agingEssenceIn view of the global public health burden of dementia and the current lack of effective treatment,Determine the risk factor that can be changed or preventedIt will have an important impact on the occurrence and development of dementia.

The discovery of this study prompts us,Irregular sleep may be a potentially changing risk factor for dementiaEssenceTherefore, while maintaining adequate sleep time, maintaining the regularity of sleep time may be a potential way to prevent the first -level prevention of dementia.

Dr. Matthew P. Pase from the University of Monash University said that most people will pay attentionRarely pay attention to the hazards of irregular sleep"Our results show that the association between the regularity between sleep and dementia has nothing to do with sleep quality and duration. This indicatesThe regularity of sleep is an important part of the healthy sleep that we should pay attention to"" ".

Maintaining regular sleep is an easy way to adjust.With the application of various measurement devices and smartphones, people can find out whether they have regular sleep.For people with irregular sleep, we must take measures to ensure the regularity of sleep.Develop a regular bed and getting up to reduce the risk of dementiaEssence
