Middle-aged people with less than 6 hours sleep may increase the risk of dementia!
Middle-aged people with less sleep may increase the risk of dementia! About one-third of a person’s life is spent in sleep, but in today’s fast pace of life, being able to sleep 8 hours a day seems to be a luxury. However, enough sleep cannot be guaranteed. The body brings no small harm.
Recently, the US health information website WebMD published a paper saying that a study published on Nature Communications showed that middle-aged people sleep less than 6 hours a night, which may lead to an increased risk of dementia.
The study included sleep data of 7,959 participants from the United Kingdom, and each participant was followed up for 25 years. During the follow-up period, a total of 521 cases of dementia were diagnosed. Analysis of the data shows that among people in their 50s and 60s, people who sleep only 6 hours or less per night are diagnosed with dementia compared with those who sleep normally (defined as 7 hours) The probability is 30% higher.
Dr. Séverine Sabia, a researcher from the French National Institute of Health and Medical Research, explained that their study can still prove that middle-aged people lack sleep after eliminating mental illness and other chronic diseases known to be related to dementia. There is indeed an association with an increased risk of dementia.
But because the brain changes that lead to dementia have begun many years before the diagnosis, Dr. Elizabeth Coulthard, senior lecturer in dementia neurology at the University of Bristol, said that this study can only prove that lack of sleep is associated with a high risk of dementia, but it cannot prove that Does it trigger or exacerbate dementia.
In addition, another participant in the study, Tom Dening, director of the Dementia Center at the University of Nottingham Institute of Mental Health, also said that although the two are highly correlated, too short sleep time may also be an ultra-early symptom of dementia. Not the cause.
Finally, I want to remind everyone that whether middle-aged people can reduce the risk of dementia after 7 hours of sleep, it is our body’s daily “just need” to ensure good and adequate sleep, because in addition to dementia, lack of sleep will also give us Brings various negative effects such as lack of energy, poor skin, dizziness, weakened immunity, irregular eating and so on.
Therefore, the daily habit of not contacting caffeine before going to bed and not taking mobile phones to bed will help us to improve sleep quality and ensure the length of sleep, which will help us maintain a regular schedule and thus protect our health.
