—The elderly need to be vigilant about Cardiovascular and cerebrovascular diseases —
Central Meteorological Observatory html 2nd half of this year, which is also the earliest cold wave warning issued in the second half of this year since the Central Meteorological Observatory launched the current warning release mechanism in 2010.
Facing this sudden drop in temperature
patients with cardiovascular and cerebrovascular diseases
Especially the elderly should pay attention to the body
Avoid cold weather
Become the fuse of cardiovascular and cerebrovascular diseases
What is the relationship between cold wave and cardiovascular and cerebrovascular diseases ?
The onset of cardiovascular and cerebrovascular diseases is related to blood pressure. When the cold wave comes, people's blood pressure will fluctuate, and the cerebrovascular and cardiovascular capacity is the greatest.
In addition, when the cold wave comes, people will experience stress reactions when resisting extreme cold outside, which will promote the discharge of some stress hormones in the body and increase the burden on the cardiovascular and cerebrovascular.
When the cold wave comes, due to the low external humidity, people are prone to dehydration and blood flow will change. These combined factors cause cardiovascular and cerebrovascular diseases to multiply in extremely cold weather.
What methods can prevent the attack of cardiovascular and cerebrovascular diseases
1
Add to get up early
Due to the cold weather, most people have the habit of staying in bed, and some people even cover their heads and sleep, but they don’t know that this behavior will cause the oxygen in the quilt to decrease, which will affect breathing, and thus cause cardiovascular disease.
Therefore, be careful not to get up immediately after waking up. First, lie flat for three minutes and then sit quietly for three minutes, and finally get up and walk around. If you wake up all of a sudden, it will lead to insufficient blood supply and cause orthostatic hypotension , which is also extremely easy to cause cardiovascular and cerebrovascular diseases.
2
Keep warm
Avoid cold invasion. Due to the drop in temperature, the body is easily invaded by cold invasion, causing coronary artery to contract, which in turn causes myocardial ischemia to increase the burden on the heart, causing a series of cardiovascular diseases.
Therefore, when going out, you should take warm measures and add clothes according to the temperature.
3
Exercise should pay attention to
Although exercise can promote blood circulation in winter, you should pay attention to choosing to exercise outdoors after the sun comes out.
Do not exercise in the morning from 5 to 6 o'clock in the morning. This is the lowest temperature, which can easily cause blood vessel contraction and allow colds to invade.
4
Control the water temperature for bathing
In winter, because the weather is cold, many people will have higher water temperatures when taking a bath, but for middle-aged and elderly people, you should pay great attention.
Because the water temperature is too high, a large amount of water vapor will be generated, which will cause insufficient oxygen content in the bathroom. In this case, the heart's blood supply and oxygen supply are prone to problems, which leads to disease attacks, so the bathing time should be kept at about 15 minutes.
3 "half minutes"
What are the common phenomenon of arteriosclerosis in the elderly? What are the three "half minutes" that everyone is talking about?
The temperature drops sharply. For the elderly, after waking up in the morning, leaving the warm bed, the temperature difference is relatively large. Getting up immediately can easily cause orthostatic hypotension, fainting, insufficient myocardial blood supply, angina pectoris attack, myocardial infarction and other accidents.
So, these 3 steps are very important.
1
After waking up, lying in bed for half a minute. Stretch and don't get up immediately and go down to the floor.
2
Sit up and lean on the head of the bed for half a minute. This semi-sitting position starts to increase the burden on the heart and blood vessels. This is an adaptation process, a warm-up process.
3
Sag your legs and wait for another half a minute. This is another warm-up to adapt the cardiovascular system to an upright state.
In addition, many people in life have a habit of waking themselves up with an alarm clock. Sometimes, alarm clock is not next to the pillow, so I stand up and turn off the alarm clock. This action is extremely dangerous, especially for elderly people, who suddenly turn over and get up can easily fall.
On the basis of fully paying attention to the disease, the elderly with cardiovascular and cerebrovascular diseases keep warm, exercise properly, live regularly and take medicine on time. I believe that every elderly person can be prepared to fight the enemy of "cold".
