Thrombosis, a vascular disease that is more common in middle-aged and elderly people, is usually blocked by factors such as high blood lipids, blood sugar concentrations, and increased lipid plaques on the blood vessel walls. This condition is medically defined as a blood clot.

In particular, blood clots located near the brain and heart often require special attention, because blood clots in these areas may become the direct cause of some acute diseases and pose a greater threat to life and health. Therefore, if the following four abnormal conditions appear in the body during daily sleep, you should also pay enough attention, which may be a sign that blood clots are forming, and you should seek medical attention in time.

1. Difficulty breathing after lying down

From a human anatomical point of view, when people lie flat, the airways are relatively narrowed by gravity, which can lead to poor breathing. The heart and lung function are closely linked, and if the blood vessels near the heart are blocked, affecting the efficiency of the pulmonary circulation of the blood, the difficulty of gas exchange between the lungs and the outside world will increase, which will further deteriorate the breathing state.

Therefore, if you feel chest tightness and shortness of breath or have symptoms of sleep apnea syndrome during sleep, you should get a cardiovascular health check as soon as possible to avoid the condition from worsening without realizing it.

2. Drooling while sleeping

At night, the body's fluid-secreting glands are less active and can still control the glands when the blood supply to the brain is sufficient, so there is generally no large amount of saliva secretion. However, if the blood supply to the brain is blocked and the health of the cerebrovascular system is problematic, the control of facial nerves and muscles becomes unstable, which may lead to the phenomenon of saliva at night.

In addition, if you often have symptoms such as crooked mouth and slanted eyes, slurred speech and other symptoms in daily life, you should also be alert to possible signs of cerebrovascular disease.

3. Numbness of hands and feet while sleeping

The hands and feet serve as the ends of the blood circulation in the upper and lower body, which can directly reflect the state of blood circulation. If you often feel cold, numb, and tingling in your hands and feet during sleep at night, it may indicate a major circulation problem and be alert to vascular embolism. Of course, for such problems, soaking your feet in warm water before bed may help improve sleep.

4. Pain in the head after lying down

During nighttime sleep, the body's basal metabolic rate decreases, causing blood flow to slow down and blood concentrations to rise. If there is embolism in the blood vessel, the symptoms of blood congestion will be exacerbated, and there may be strong irritation to the outer wall of the blood vessel and peripheral nerves, which may manifest as headache, dizziness and other symptoms.

This condition not only affects the quality of sleep, but can also be the cause of sudden vascular disease at night. If similar symptoms occur frequently, it is necessary to seek medical attention in time to prevent the condition from worsening.
