Into ambush
The heat hit
Let's protect the heart!
Dog days of summer
It is the hottest period in China during the lunar year
Rising temperatures
High incidence of cardiovascular disease
With the increase of temperature, the subcutaneous blood vessels of the human body expand, the blood flow of the skin increases by 3~5 times than usual, and the load on the heart will increase.
A study published in the journal Environment and Health showed that for every 1°C increase in maximum temperature, the number of patients with cardiovascular and cerebrovascular diseases in the emergency department increased by 17.3%.
There is epidemiological evidence that temperature is strongly associated with cardiovascular disease. The impact of extreme heat (average 29.0°C) on the risk of death is rapid and short-lived, and is immediately apparent on the same day.
When temperatures are above 32°C, the incidence of stroke (stroke) is 66% higher than usual, and the risk increases as temperatures rise.
high temperature
Why "sad"
When the temperature rises, the subcutaneous blood vessels expand, and the blood flow on the body surface increases, which reduces the blood supply to the heart and brain, which is easy to cause cardio-cerebral ischemia and hypoxia.
Heavy sweating in summer, if not hydrated in time, can easily lead to excessive body fluid loss, increased blood viscosity, slowing down blood flow rate, and easy to cause thrombotic events.
An increase in ambient temperature may cause a drop in blood pressure, but reduced doses of antihypertensive therapy may lead to an increase in blood pressure at night.
Frequent use of air conditioning, with the sudden change of ambient temperature, blood vessels suddenly contract or expand, so that the fragility of blood vessels increases, easy to trigger cardiovascular and cerebrovascular events.
Nourish the heart
Cool the cardiovascular system
Stay hydrated at all times
* In summer, healthy people should drink no less than 2000-2500ml of water per day
* Small mouthfuls many times to avoid heavy irrigation to aggravate the heart load
Eat a light diet
* Meals should not be too salty, too much salt will increase blood pressure
* It is best to eat seven minutes full, too full will increase the burden on the heart
* Minimize the intake of cold, spicy and stimulating foods
Take a half-hour nap every day
* Take a nap for 30 minutes, which is conducive to the stability of blood pressure and heart rate
* It is better to take a nap lying down at an interval of 20 minutes after lunch
The temperature of the air conditioner should be suitable
* Do not blow the air conditioner immediately after leaving the hot environment, it is difficult for the cardiovascular system to adapt to the excessive temperature difference
* Air conditioning temperature is best at 26°C
Avoid cold showers
* The outdoor temperature is high, and direct showering is easy to make the blood vessels contract violently, resulting in spasm, dizziness and nausea
* It is recommended to dry the sweat on the body first, rest for 15 minutes before bathing with warm water
Morning exercise is changed to evening exercise
* Patients with coronary heart should avoid morning exercise, at this time, after a night of sleep, the blood becomes thick, the flow rate slows down, and it is easy to aggravate blood clots
* Moderate exercise at night can be done to avoid too long time and excessive exercise, resulting in myocardial ischemia
