Summer is coming, and the sun is getting early. People who love morning exercises have also moved up their daily exercise time in order to avoid the heat. But are cardiovascular patients suitable for this? Although there is no threat of low temperatures in summer, is it really advisable to practice in the morning?
The above real cases tell us that the risks of morning exercise for patients with cardiovascular disease may be greater than the benefits.
1 Morning exercise! Your blood vessels are undergoing a "test"
For patients with cardiovascular disease, they generally know clearly that the reason why their blood vessels undergo "accidents" after strenuous exercise or temperature changes is because The blood is thick and the blood circulation is not smooth. Under the catalysis of "thermal expansion and contraction" conditions of blood vessels, strenuous exercise, temperature differences, morning air changes, etc., can easily lead to cardiovascular and cerebrovascular events.
No matter winter or summer, your blood vessels are going through the "test" of morning exercise.

2 Why it is not recommended to do morning exercises in summer
For people who suffer from cardiovascular disease and love morning exercises, choosing to do morning exercises in summer has many dangers for them.
01 Early morning cardiovascular high incidence stage
According to relevant surveys, 40% of myocardial infarctions and 29% of sudden cardiac deaths occur in this stage, and the highest incidence of stroke is also in other areas. Period 3-4 times.
02 Morning exercise on an empty stomach, blood viscosity can induce blood clots
Cardiovascular patients do not drink water overnight, but exhale a lot of water through breathing, blood viscosity increases, and various functions of the human body in the morning are affected. It takes a certain amount of time to recover. If you perform morning exercises on an empty stomach in this situation, it can easily lead to the occurrence of blood clots.
03 Morning exercise without medication
Many cardiovascular diseases in the early morning are related to the patient’s immediate activity after waking up. In addition, many patients who exercise in the morning are accustomed to taking medicine and eating breakfast after exercising, when the blood drug concentration is lowest, which often provides opportunities for cardiovascular events to occur.
04 The period when the sympathetic nerve is excitable will affect the increase in blood pressure
Human blood pressure fluctuates 24 hours a day, which is normal. However, blood pressure is lowest between 2 and 3 a.m., and when the sympathetic nerves are excited between 6 and 9 a.m., blood pressure will reach or be close to its peak. It is very dangerous for patients with cardiovascular disease to choose to do morning exercises.
05 Too early, too few people can get help in time
