Uncle Wang takes a nap for more than an hour at noon every day. This was a common thing, but recently he saw such an article and felt that the longer the nap time, the worse the memory would be, which would increase the chance of suffering from Alzheimer's . He was very scared. If he didn't take a nap at noon, he would be particularly energetic in the afternoon.
Later, in desperation, Uncle Wang went to the hospital with his family and asked the doctor if the elderly would have more than one hour off lunch to increase the risk of Alzheimer's disease? The doctor said that taking a proper nap will not increase the risk of Alzheimer's disease, but taking a nap must be controlled well, otherwise you will easily be unable to sleep at night and will suffer from insomnia.

Nap Latest research: Does the elderly have a nap for more than one hour, and will the risk of Alzheimer's disease increase by 40%?
Nap is a living habit that needs to be praised and promoted by people. Research shows that taking a half hour nap can greatly reduce the probability of heart disease, but it should be noted that the nap time should not be too long, because the nap time is too long, which may increase the incidence of Alzheimer's disease.
Recently, a scholar in the United States followed up and analyzed 1,401 elderly people with an average age of 81 years old, and the relationship between nap status and Alzheimer's disease was found. The results showed that there was a two-way relationship between nap time and Alzheimer's disease. Too much nap too long will increase the risk of Alzheimer's disease in the future, and Alzheimer's disease will also cause patients to take excessive naps during the day.
Overall, compared with those who take less than one hour a day, people who take more than one hour a day have a 40% higher risk of developing Alzheimer's disease. It is recommended to limit the nap time to 15 to 20 minutes before 15 o'clock to obtain the greatest health benefits of nap and prevent damage to night sleep.
It is recommended that everyone should control the nap time within 30 minutes. The sleep time is within this time range. The person's awakening and emotional attention can be improved. When you wake up, you are comfortable, have a good mental state, and you don't feel sleepy. If the nap time exceeds 30 minutes, the body will have shallow sleep and enter a deep sleep that is not easy to wake up. If you are awakened in a deep sleep state, the brain will have temporary relative blood supply deficiency, and you will be tired and fast after waking up, and you will be very tired.

So, what are the causes of Alzheimer's disease?
Alzheimer's disease is a common disease in life. This disease not only brings great pain to patients, but also adds a great burden to their families. So what are the factors that induce Alzheimer's disease? Let’s learn about it together below.
. Tumor: Malignant tumors cause metabolic disorders, which can lead to dementia. Brain tumors can also directly damage brain tissue, leading to dementia.
, syphilis : The spirochete of syphilis can invade the brain, produce mental and neurological symptoms, and eventually lead to paralysis, and increasingly aggravate intellectual loss and personality changes. This is the so-called paralytic dementia .
3, AIDS : AIDS is one of the causes of Alzheimer's disease. It is known that the elderly suffer from AIDS and progressive dementia can occur in the early stage. It has been proven that it is central nervous system , which can directly infect human immunodeficiency virus.
4. Drugs and other substances poisoning: Alzheimer's disease caused by chronic alcoholism is not uncommon. Long-term exposure to aluminum, mercury, gold, silver, arsenic and lead, etc., poor protection, which can lead to chronic poisoning. Carbon monoxide poisoning is also one of the common causes of Alzheimer's disease.
5. Nutrition and metabolic disorders: Due to nutrition and metabolic disorders, brain tissue and its functions are damaged, resulting in dementia. For example, encephalopathy caused by various organs, such as renal encephalopathy, ischemia and hypoxia caused by uremia can lead to dementia.
Others such as hepatic encephalopathy , pulmonary encephalopathy , etc. can all lead to dementia, severe nutrition, lack of vitamins B1, B12 and niacin, folic acid deficiency can all lead to Alzheimer's disease, diabetes and hyperlipidemia can all cause atherosclerosis of the angiovascular system of the middle artery, thickening of the basement membrane of small blood vessels and microvascular vessels, which can cause cerebral infarction and cerebral hemorrhage , resulting in vascular dementia .
6. Other causes of Alzheimer's disease: such as brain trauma , continuous seizures of epilepsy, normal stress, hydrocephalus and other causes, which can all cause Alzheimer's disease. If the elderly are prone to being out of place for a long time, live alone, widowed, illiterate, low language level, lack of physical strength and brain exercise, etc., it can also speed up the process of brain aging and induce Alzheimer's disease.

What are the precautions for taking a correct nap?
Many people think that the longer the nap, the better. In fact, the nap time should not be too long. If it is too long, it can easily lead to headaches and weakness throughout the body, which is more fatigued than not taking a nap. It is recommended that everyone take a nap time within 15 minutes to half an hour, and not more than one hour, so that they can get enough rest during the nap.
Many people can’t wait to sleep after lunch. In fact, it is unhealthy to rush to sleep in the afternoon. At this time, the stomach has just been filled with food and blood flows to the stomach. The brain will have insufficient oxygen supply. At this time, a hurry to take a nap can easily lead to insufficient blood supply to the brain. Therefore, it is recommended to exercise for a while after lunch before starting a nap.
Don’t be too greasy when you eat lunch. If you eat more full and greasy, the burden on the stomach will increase the greasyness in the vegetables will also increase the viscosity of the blood, causing some lesions. Therefore, you can drink a glass of water or take a short walk after lunch to dilute the viscosity of the blood.
If you have the conditions, try to lie down and rest at noon, because sleeping on the table for a long time can easily compress the nerves on your face and arms, and at the same time it will also press on your eyes, causing blurred vision and other symptoms. It is recommended that friends who are close to the company should go back for lunch, which will have many benefits for your health.
