That day, the weather was fine, and Uncle Zhang left suddenly. Uncle Zhang is 57 years old, never smokes or drinks, and is said to be a healthy person, but just one morning a week ago, he suddenly collapsed due to a cerebral infarction and never got up again.
He was an ordinary postman who rode his bicycle to the streets of the city all day. Before his retirement, he insisted on delivering every mail rain or shine.
In the last days of the hospital, the doctor gave a detailed account of his condition. "In fact, Uncle Zhang's three highs have been checked, and the results are normal, and he never smokes or drinks, so it stands to reason that the risk should be very low. However, he has three habits that make him a potential killer. The doctor said.
First of all, Uncle Zhang has the habit of drinking strong tea before going to bed. Many people believe that drinking tea is good for health, but the caffeine content in strong tea is high, and drinking it at night can easily lead to a decrease in sleep quality. Long-term sleep deprivation and poor quality have been linked to an increased risk of cerebrovascular disease in several studies.
Secondly, Uncle Zhang has the habit of lying down and resting immediately after eating. This seemingly innocuous action can actually lead to indigestion and acid reflux, which may affect heart function and indirectly increase the risk of cardiovascular disease in the long run.
The third habit is that he likes to sleep at night with the window open. While ventilation can help improve indoor air quality, low temperatures and humidity at night can be a test for the cardiovascular system of middle-aged and elderly people.
Sudden temperature changes tend to cause blood vessels to constrict and increase the incidence of cardiovascular and cerebrovascular accidents. When the temperature difference between indoor and outdoor is large, the acute attack rate of cardiovascular and cerebrovascular diseases increases significantly.
Through these analyses, doctors hope that more people are aware that small changes in daily habits can have a big impact on health.
Just after the doctor finished explaining, Uncle Zhang's son asked, "Doctor, my father likes to open the window for ventilation before going to bed, we think this is a good habit, why is it not good for him?"
The doctor replied: "Opening windows for ventilation is a good thing in itself, especially in the environment we live in, where the air is often worse than outside. But the key is to choose the right time and how. '
"In middle and old age, the body gradually loses its ability to adapt to the external environment. If they insist on opening windows for ventilation at night, especially during the harsh winter months, this temperature difference can pose a considerable challenge to the heart and blood vessels.
In this case, blood vessels may contract suddenly, causing an increase in blood pressure fluctuations, which in turn puts an additional burden on the heart and may also be more likely to trigger cerebrovascular disease outbreaks.
Therefore, the elderly should pay attention to maintaining the stability of indoor temperature and avoiding ventilation at night to maintain good health.
In fact, we need to note that although ventilation is necessary to maintain indoor air quality, it is more prudent for the elderly, especially those with cardiovascular and cerebrovascular diseases, to appropriately reduce the time and frequency of opening windows at night, or choose to do it on warmer days.
This is not just a small adjustment to traditional concepts, but is based on an in-depth understanding and respect for the physiological characteristics of the elderly.
Older people are at increased risk of cardiovascular and cerebrovascular events when they sleep in cold environments. Those who insisted on sleeping with their windows open during the cold season had significantly higher rates of heart disease and cerebrovascular disease in the winter compared to those who chose to maintain a warm sleeping environment.
What we can do in this regard is to adjust the timing of window openings appropriately while maintaining indoor air quality. For example, open windows for ventilation during warm days and use air purifiers at night to maintain air quality while reducing health risks due to temperature differences.
In this way, we can not only ensure the freshness and health of indoor air, but also better take care of the cardiovascular and cerebrovascular health of the elderly. This advice, which is based on scientific research and life practices, aims to help more older people enjoy their old age safely and healthily.
