Going to bed immediately after meals is also very harmful to the elderly.
With the growth of human age, the function of nerve cells is gradually declining. Old people sleep less than young people and wake up easily, so they are prone to fatigue. Old people often doze off during the day and want to sleep, especially after lunch. This practice is harmful to the health of the elderly. Recently, medical experts in the Federal Republic of Germany pointed out that there are certain dangers for three kinds of people to take a nap after meals: the elderly over 65; Obese people whose weight exceeds 20% of the standard weight; People with extremely low blood pressure or serious disorder of blood circulation system, especially those who often feel dizzy due to narrowing of cerebral vessels. Most elderly people have arteriosclerosis, especially obese people. Hyperlipidemia can easily cause arteriosclerosis of arteries and cerebral arteries, which often leads to insufficient blood supply to the brain. After eating, the blood circulation in digestive tract is vigorous, the blood flow in brain is relatively reduced, and sleep is still, which is easy to aggravate the local blood supply deficiency in brain. There is a health proverb in our country, "Lying down while eating is sick." Therefore, after eating, the elderly should not sleep immediately, but do some light activities to facilitate blood circulation.
In addition, I will show you a piece of news, and you will also gain something:
Japanese researchers have found that if you often feel heartburn and chest pain while sleeping, you should go to bed three hours after dinner. The study was completed by Dr Tayo Fujiwara of osaka city university and his colleagues, and the results were published in the American Journal of Gastroenterology.
The researchers found that heartburn and chest pain originated from gastroesophageal reflux disease, and the interval between dinner and going to bed was closely related to gastroesophageal reflux disease. Gastroesophageal reflux disease (GERD) is a common disease and a dynamic disease of the upper digestive tract, which is closely related to acid and bile reflux, as well as stimulation and injury to esophagus and outside esophagus.
The research team led by Dr. Fujiwara investigated 147 patients with gastroesophageal reflux disease and 294 healthy people. The results showed that the shorter the interval between dinner and sleep, the higher the risk of gastroesophageal reflux disease. Subjects who went to bed within 3 hours after meals were 7.45 times more likely to suffer from heartburn than those who went to bed 4 hours or more after meals. According to these data, Professor Fujiwara and other researchers believe that people should put off going to bed after meals.
Also tell you some other bad sleep habits, you should pay attention. These are trivial things in daily life, but they are common health knowledge that you should pay attention to every day ~ ~ protect yourself and protect the people around you! ! !
Sitting and sleeping will slow down the heart rate, dilate blood vessels and reduce the blood flow to various organs. In addition, stomach digestion needs blood supply, which aggravates brain hypoxia and leads to dizziness and tinnitus. Especially in the elderly, the myocardial function is poor, so we should pay more attention not to sit and sleep.
Get up immediately after waking up. When I wake up, I feel my heartbeat is slow, my blood supply is less, and my cardiovascular and cerebrovascular diseases will contract relatively. If you get up immediately, cardiovascular and cerebrovascular diseases will expand rapidly, and the brain excitability will be strengthened, which is easy to cause cerebral hemorrhage. So, after waking up, rest in bed for three to five minutes before getting up. The elderly and patients with cardiovascular and cerebrovascular diseases should pay more attention to this.
Sleeping with a watch Some people like to sleep with a watch, which will not only shorten the service life of the watch, but also be harmful to the health. Because people's blood flow slows down after falling asleep, sleeping with a watch will make the blood circulation of the wrist not smooth. If you wear a noctilucent watch, there is also the influence of radiation. Although the amount of radiation is small, long-term accumulation will lead to adverse consequences.
In order to prevent false teeth from falling into the esophagus or trachea, it is best not to wear them when sleeping. People with complete dentures can sleep with dentures before they get used to it, which can speed up the habit process. After getting used to it, you should take off your dentures before going to bed, soak them in cleaning solution or cold water, rinse your mouth in the morning and put them in your mouth.
Some people put their mobile phones on their pillows at night for the convenience of talking. When the mobile phone is turned on, it will release a large number of electromagnetic waves with different wavelengths and frequencies, forming electronic fog, which will affect the physiological functions of the human nervous system and other organs and tissues. Studies by foreign scholars also show that cell phone radiation can induce cell canceration.
Wearing a bra to sleep means that wearing a bra to sleep is easy to cause breast cancer. The reason is that wearing a bra for a long time will affect the blood circulation of the breast and the normal circulation of some lymph nodes, and it will not remove harmful substances in the body in time, which will make normal breast cells cancerous over time.
Some women, especially young women, often go to bed without makeup removal. Sleeping with residual makeup, cosmetics will block skin pores, cause sweat secretion disorder, and hinder cell breathing. In the long run, it will induce acne and damage the face. Therefore, it is necessary to remove makeup and wash your face before going to bed. Remove the stimulation of residual makeup on the face in time and let the skin breathe fully, which not only keeps the skin moist, but also helps to fall asleep as soon as possible.
