Recently
there is a news that a 19-year-old boy died of sudden myocardial infarction after intense exercise
Heavy drinking of cold drinks
is deplorable
Heavy drinking of cold drinks after exercise
Why can it induce myocardial infarction?
Doctors introduce
Summer temperatures are high
Human blood vessels are in a state of expansion
After strenuous exercise
The body suddenly encounters cold stimulation
For example, drinking a lot of cold drinks, blowing air conditioners, taking cold showers, etc.
can easily lead to systemic vasoconstriction and spasm
induce angina pectoris and myocardium Infarction
1
Hot summer
"Alternating hot and cold"
will put the body under these health burdens
Indigestion
One cold and one hot
It is easy to cause gastric indigestion
For example,
Eating hot pot and drinking iced drinks will stimulate gastric vasoconstriction
Slowing of gastrointestinal motility
Reduced secretion of digestive juice
Temperature drop
Digestive enzyme activity will also be reduced
Gastroenteritis
Alternating hot and cold strongly stimulates the stomach
It is easy to cause gastric cramps or stomach pain
Over time
may induce gastritis Or enteritis
cardiovascular and cerebrovascular diseases
people with poor cardiovascular and cerebrovascular conditions
are more afraid of alternating hot and cold stimulation
like high blood pressure , coronary heart disease
atherosclerosis patients, etc.
blood vessel self-regulation ability is relatively poor
eating The "sudden cooling" after hot food causes vasoconstriction
It may
induce angina pectoris, myocardial infarction, cerebral embolism etc.
Headache
The brain is very sensitive to temperature
Increased blood flow
When blood vessels expand
warm blood can be input into the brain
Keeps the brain warm
Sudden changes in blood flow can create pressure
Cause headaches

It is best not to do these things in hot weather
Stay in an air-conditioned room 24 hours a day
When the weather is hot
Many people like to stay in an air-conditioned room all day
Such an approach is not advisable
If the air conditioner is not cleaned all the year round
it will adhere to a variety of health-threatening germs
Once inhaled by the human body
it will cause varying degrees of respiratory infections
and even lead to "air conditioning lung"
So how to blow the air conditioner healthily? ?
When you sweat, you should wipe off the sweat first and then use the air conditioner. Don't sleep with the air conditioner on. The air conditioner should not be used for too long. Generally, if the air conditioner is turned on for two or three hours, the windows should be opened for ventilation for half an hour. When blowing the air conditioner, you must protect your cervical vertebrae, shoulders, knees, ankles and other parts. Do not blow the air directly on your body. If necessary, you can install a windshield for the air conditioner.
Drink water when you are thirsty
The weather is hot
Sweating a lot makes you prone to thirst
Many people are used to picking up a cup and drinking water
Proper drinking of water in summer
can replenish the body's missing water
Reduce blood viscosity
But drinking it all at once is too much Too much
moisture will quickly enter the blood
causing blood volume increase
easy to increase the burden on the heart
causing chest tightness , shortness of breath, difficulty breathing and other symptoms
bathe with cold water
the weather is hot in summer
the pores of the human body are open
wash Cold shower
Cold air can easily invade the body
and cause Yang Qi to be damaged
Experts say
Taking a warm water bath in summer
can not only wash away sweat stains and dirt
make the skin clean and cool
which is good for relieving the heat
but also speeds up blood circulation
and improves the nutrition of skin tissue.
Reduce muscle tension
Eliminate fatigue and improve sleep
Enhance disease resistance
Have you mastered all these knowledge points
?
Don’t be greedy for coolness when cooling down in summer~
