During the National Day, the 69-year-old Lao Sun was mixed. Qianjiao just attended his nephew's wedding and watched a couple start a new family under the blessings of relatives and friends, opening a new stage of life. Lao Sun was happy from the bottom of his heart. But who knew that just one day later, Lao Sun received the news that his former classmate suddenly passed away. This classmate was a famous table tennis master when he was young. Not only did he have good skills, but he was also strong in physical strength. He often fought against three people without any disadvantage at all. So his sudden death shocked Lao Sun. Although he knew that his old classmate suffered from atherosclerosis, he had always taken medicine on time and controlled it well. Why did he still leave so suddenly?
After carefully asking the old classmate's family, I realized that it turned out that the temperature dropped sharply by more than ten degrees a day because it rained a few days ago. Lao Sun's classmate went to the table tennis hall to play basketball and sweated. He left the stadium without putting on his coat immediately. As a result, he suddenly suffered an acute myocardial infarction of on the road, and eventually died after failed rescue.
In fact, everyone will also find that as autumn and winter changes, the number of elderly people who die suddenly as if they were Lao Sun’s classmates increased significantly. Many people came to ask Master Wang, why is this? Today, Pharmacist Wang will give you a good explanation. For the elderly, how dangerous is it to the sudden drop in the temperature during the season change!
1. Why is the sudden drop in temperature so dangerous for the elderly?
For the elderly, as they age, their mobility begins to decline, their metabolic function decreases, their heat production decreases, and their temperature regulation function begins to deteriorate. In addition, the elderly are generally chronic diseases such as excessive blood pressure and arteriosclerosis. Once the temperature drops sharply, it is easy to cause diseases and endanger life and health.
1, cardiovascular disease
European researchers conducted a 16-year follow-up survey. By reviewing the data of nearly 2.28 million adults from 1994 to 2010, the analysis found that when the temperature drops by 10°C, it will increase the risk of cardiovascular disease death by 19%. Low temperature stimulation will narrow blood vessels to minimize heat loss in the blood and regulate normal temperature inside the body. Vascular contraction causes increased blood pressure and accelerated heart rate, because the heart needs to work harder to pump blood through the contracted blood vessels, thereby increasing the burden on the heart and brain.
For people with cardiovascular health, this vascular contraction will not cause too much problem, but for the elderly who frequently experience coronary heart disease and hypertension , this sudden change in ambient temperature may cause plaque rupture and artery blockage, which will lead to myocardial infarction. In addition, patients with hypertension may also cause stroke due to the sharp rise in blood pressure, which is life-threatening.
2. Respiratory system diseases
The temperature drops sharply. When the human body inhales dry cold air in autumn and winter, it will stimulate the local mucosa of the nasopharynx. In severe cases, it may lead to contraction and spasm of the tracheal smooth muscle, causing lung ventilation dysfunction, which will cause asthma . In addition, when the mucosa of the nasopharyngeal is in a dry state for a long time, the mucosa will dry and crack, which gives viruses and bacteria an opportunity to take advantage of it, causing a high incidence of respiratory diseases.
3, Falling
As the saying goes, "A autumn rain and a cold." In addition to the sudden drop in temperature, the slippery ground during rain also hides a crisis. Rainwater gathers on the ground and forms thin ice at low temperatures. If the elderly do not pay attention, they will be at risk of falling. As we age, bone density decreases, sarcopenia, etc. greatly reduces bone strength, so fragile fractures are very prone to occur. lung infection with is one of the most common complications of fractures in the elderly, posing a serious threat to the lives and health of the elderly. Therefore, some people call the fall after the age of 65 a "last fall in life."
2. How should the elderly respond when the temperature drops sharply?
To deal with temperature changes in autumn and winter, the elderly should take precautionary measures in advance, and pay special attention to the following 5 points in order to maintain a good health when the autumn and winter seasons change.
1. Add clothes to keep warm
When the temperature in the external environment drops, the elderly should add clothes to keep warm in time and minimize the time spent outdoors. In particular, pay attention to keeping warm on their hands and faces. If necessary, wear hats, socks, etc.
2. Do not exercise quickly or urgently
In autumn and winter, the elderly should avoid choosing fitness methods that are too intense when exercising. Do not exercise too fast or too fast. It is best to choose walking, Tai Chi and other exercises. The time should not be too long, and exercise moderately.
3. Pay attention to the foot
0 mentioned above that falling down by the elderly will directly endanger their lives. Therefore, the elderly should always be careful of their feet and prevent slippage when going out, and try to choose sunny and good vision to go out.
4. Reasonable diet
As autumn and winter seasons come, people always like to sit around the table and eat some high-calorie food to satisfy their taste buds. Many people have even put on "Autumn weight", but the elderly should pay attention to the "salt limit and weight loss" that protects the cardiovascular and cerebrovascular system. Reasonable diet also needs to pay attention to it in autumn and winter. In addition, if the blood pressure rises after cooling, in addition to reducing salt intake, you can also drink some foods with diuretic effects such as red beans and coix seed porridge , which can reduce the body's water and sodium retention and reduce blood volume by increasing the amount of urine.
5. Restricted drinking
Many elderly people like to drink a drink in the low temperature autumn and winter. After drinking, they feel warm all over. However, they do not know that this behavior has hidden dangers, especially drinking before going out. Because alcohol can expand blood vessels in the skin, although the body feels warmer, it actually draws calories from other organs. And excessive drinking can also cause cardiovascular and cerebrovascular diseases , so the elderly should try to drink less.
