A year later, in the middle of the night, Lao Zhao had chest pain again, only this time the chest pain was more severe than usual, and it lasted for a long time without subsiding. But Lao Zhao still did not want to go to the hospital, he felt that sleeping would be good, but what people never expected was that Lao Zhao died that night.

The doctor said that the real cause of Mr. Zhao's sudden death was heart disease.

Sudden death is defined by the World Health Organization (WHO) as: "Sudden death occurs when a normally healthy or seemingly healthy patient suddenly dies of a natural disease in a short period of time unexpectedly."

Many people think that sudden death comes suddenly, without any signs, but in fact it is not. A three-foot thick iceberg does not form overnight. Many diseases seem sudden, but in fact, they are the result of a long incubation period.

The doctor reminded that 1 year before sudden death, there will usually be 6 warning signs in the body, and you should pay attention to any of them, which can save your life at a critical moment.

1. Frequent fatigue, mental fatigue, physical fatigue

When you feel tired, and you do not feel better even after resting, at this time, your body is actually on the verge of collapse.

The body is the capital of the revolution. If your body is almost exhausted, how can you persevere? If you try to hold on like this, you will only push yourself into the abyss of sudden death. When you feel particularly tired, remember to go to the hospital for a proper examination.

2. Often do not sleep well for a long time, and feel sluggish and yawn every day

Even a machine cannot run all the time, and it always needs to rest properly, let alone a person. One-third of life is spent sleeping, sleep is also a process of self-repair of the body, if you do not sleep well for a long time, the body is prone to major problems.

Long-term poor sleep will lead to a decline in immunity, will make you fatter, will make your endocrine system more disordered, and in these bad environments for a long time, you are also very close to sudden death.

According to research from experts in the Department of Sleep Medicine at Harvard Medical School and Brigham and Women's Hospital, sleep disorders and sleep deprivation are associated with an increased risk of dementia and death from all causes, with people who sleep less than five hours a day more than doubling their risk of dementia and death from all causes.

3. Always feel tightness in the precordial region, as if a large rock is pressing on it

The heart is the energy pump of the human body, without a good heart, there cannot be enough blood flow to the whole body, but what many people do not know is that when the heart is not good, there will be an obvious symptom, that is, the precordial region is suffocated, many people feel like a large rock in the chest, at this time you must not ignore it, go to the hospital as soon as possible for examination.

4. Always feel chest pain, especially when moving or sleeping

Angina is the most common symptom of coronary heart disease, and patients are often more obvious when they are active or sleeping, this is the earliest and most direct warning signal of coronary heart disease, and should not be ignored.

5. Always feel dizzy and have a headache, and have a particularly hot temper

If you always feel dizzy and have a headache, and your temper is particularly hot, you should definitely go to the hospital to check your blood pressure, which is often a warning signal from high blood pressure.

Studies have found that the risk of sudden cardiac death in hypertensive patients at the age of 30 is 30% higher than that of normal people. As blood pressure increases, the risk of sudden death also increases.

6. Always feel palpitations

If you always feel palpitations that cannot be explained, please do not ignore it, you should go to the hospital early, palpitations is a condition that describes the patient's awareness of an abnormal heartbeat, manifested by the feeling of the heart beating faster, stronger or irregularly.
