老年人如何预防心脑血管疾病？
How can elderly people prevent cardiovascular and cerebrovascular diseases?
夏季由于人体新陈代谢加快，心脏大脑血液供应相对减少，会加重缺血缺氧反应。再加上气压偏低、人体大量排汗，体内水分流失多，血液循环受阻，容易诱发冠心病、中风等心脑血管疾病。可以说，夏季是心脑血管疾病发病的又一个高峰期。那么，老年人需注意什么才能安心度夏呢？
In summer, due to the accelerated metabolism of the human body, the blood supply to the heart and brain is relatively reduced, which can exacerbate the ischemic and hypoxic reactions. In addition, low air pressure, excessive sweating in the body, excessive loss of water in the body, and obstruction of blood circulation can easily lead to cardiovascular and cerebrovascular diseases such as coronary heart disease and stroke. It can be said that summer is another peak period for the onset of cardiovascular and cerebrovascular diseases. So, what should elderly people pay attention to in order to spend summer with peace of mind?
预防心脑血管意外，这6件事不可做
To prevent cardiovascular and cerebrovascular accidents, these 6 things should not be done
晨练太早
Morning exercise too early
很多老年人在夏天想趁早晨凉快时去晨练，起床特别早，但这有可能带来致命风险。相关研究表明，70%-80%的心脑血管病猝死发生在凌晨4点-上午10点。
Many elderly people want to take advantage of the cool morning to do morning exercises in the summer, getting up very early, but this can bring fatal risks. Related studies have shown that 70% -80% of sudden deaths from cardiovascular and cerebrovascular diseases occur from 4am to 10am.

Suggestion:
有心脑血管病史的老年人应尽量避开早间时段晨练；在高温天气下减少不必要的外出；可以穿浅色、透气和宽松的棉质衣服，戴上遮阳帽。
Elderly people with a history of cardiovascular and cerebrovascular diseases should avoid morning exercises as much as possible; Reduce unnecessary outings in hot weather; You can wear light colored, breathable, and loose cotton clothes, as well as a sunshade hat.
渴了猛喝水
Be thirsty and drink water vigorously
适当补水能降低血液黏稠度，但老年人喝水太快会造成血容量快速增加，很容易加重心脏的负担。尤其是患有冠心病的老年人，会出现胸闷、气短等症状，严重的可导致心肌梗死！
Moderate hydration can reduce blood viscosity, but drinking water too quickly in the elderly can cause a rapid increase in blood volume, which can easily increase the burden on the heart. Especially elderly people with coronary heart disease may experience symptoms such as chest tightness and shortness of breath, which can lead to myocardial infarction in severe cases!

Suggestion:
夏天喝水不能一次喝太多太快，要少量且多次，每次喝100-150ml。晚上睡前和早晨起床后应喝一杯水，以降低血液黏稠度，预防血栓形成，减少心脑血管疾病突发的可能。
Drinking water in summer should not be too much or too fast at once. It should be consumed in small amounts and multiple times, with 100-150ml each time. Before going to bed at night and after waking up in the morning, one should drink a glass of water to reduce blood viscosity, prevent thrombosis, and reduce the possibility of sudden onset of cardiovascular and cerebrovascular diseases.
出汗后冲凉水澡
Take a shower after sweating
夏天老年人运动后体温升高、出汗多，如果马上凉水洗脸、冲澡，这种突然的刺激不仅会造成外周血管收缩、导致血压升高，还会导致冠状动脉严重痉挛、斑块破裂，造成急性心肌梗死，危及生命。
In summer, elderly people experience increased body temperature and excessive sweating after exercise. If they immediately wash their faces and take a shower with cold water, this sudden stimulation not only causes peripheral blood vessel contraction and increases blood pressure, but also causes severe coronary artery spasm and plaque rupture, leading to acute myocardial infarction and endangering life.
建议：
Suggestion:
应先擦干身体的汗，休息10-15分钟后，再用温水洗澡。
You should first wipe the sweat off your body, rest for 10-15 minutes, and then take a bath in warm water.
午饭后立即午睡
Take a nap immediately after lunch
夏天老年人多有午睡的习惯，但午饭后立即午睡，大量的血液流向消化道，血压及大脑供氧及营养明显下降；再加上静卧不动，可能造成大脑供血不足而发生脑中风。
In summer, elderly people often have the habit of taking a nap, but immediately after lunch, a large amount of blood flows to the digestive tract, blood pressure, brain oxygen supply, and nutrition significantly decrease; In addition, lying still may cause insufficient blood supply to the brain and lead to stroke.

适当的午睡时间和入睡时间对人体健康有州苗木  保定电动门 保定空压机 化粪池模具 微型蠕动泵 保定强夯 收费岛模具益，午睡时长30分钟为宜，可在午睡后休息散步片刻后再午睡。
An appropriate nap time and bedtime are beneficial for human health. It is recommended to take a nap for 30 minutes. You can take a nap after taking a rest and walk for a while before taking a nap.
猛回头
Turn around suddenly
老年人在夏天很容易出现血容量不足、血液黏稠度高的情况。猛回头这一动作，可能造成颈动脉内不稳定的斑块“受刺激”脱落，引发脑梗，甚至威胁生命。
Elderly people are prone to low blood volume and high blood viscosity in the summer. The sudden turning back action may cause unstable plaques in the carotid artery to "stimulate" and fall off, leading to cerebral infarction and even life-threatening.
