The body's blood vessels are an important transport system that ensures that organs receive the nutrients they need to maintain good health by transporting blood to all parts of the body. However, unhealthy lifestyle habits such as unbalanced diet, sedentary, smoking, and alcohol consumption may lead to impaired vascular health, poor blood circulation, and increased blood viscosity. These factors increase the risk of cerebral infarction and cardiovascular disease, which seriously threatens our health.

When the following five symptoms are present, you should be alert to the possibility that the blood may be too thick:

Blurred vision

Because the blood is too viscous, blood circulation is blocked, which may cause insufficient blood supply to the organs. For the optic nerve in particular, an inadequate supply of oxygen and nutrients can lead to temporary blurred vision. Medically, this phenomenon is defined as "paroxysmal blurred vision" and is associated with blockage of blood vessels. If you have this symptom, it may indicate that the blood is too thick and you need to take steps to prevent the risk of stroke.

Breathing discomfort when squatting

Some people may experience difficulty breathing or irregular breathing when squatting. This is due to a circulatory disorder caused by thick blood, which prevents blood from returning to the lungs and heart. This symptom should be paid attention to, especially if blood sugar, lipids, or blood pressure are high and medical help should be sought to determine the cause.

Limbs are often numb

When blood vessels become clogged and blood becomes viscous, normal blood circulation is affected, often manifesting as numbness in the limbs. This is because of poor blood circulation at the ends of the limbs, which is a symptom caused by insufficient blood supply. If this happens frequently, you should be alert to possible signs of blockage in your blood vessels, and caution should be taken to prevent the possibility of stroke.

Frequent feeling of dizziness

Usually, people feel refreshed after a night's rest. However, for people with viscous blood, blood vessels may become blocked, and blood circulation is poor, resulting in frequent feeling of lightheadedness due to lack of blood and oxygen to the brain. If you experience this condition often, consider whether it's because the blood is too thick and take proper precautions to avoid a stroke.

Swelling of the limbs and bruising of the skin

If you observe bruising under your skin, it may be the result of a buildup of blood under your skin, indicating that there may be a serious thrombosis. The thickening of the blood causes fluid to collect, which in turn causes the limbs to swell.

There are four ways to effectively regulate blood viscosity:

1. Engage in regular physical activity: Exercise can boost your heart and improve blood circulation. People who love sports tend to have a stronger immune system, a healthier body, and better blood flow.

2. Quit smoking and limit alcohol consumption: Long-term smoking and excessive alcohol consumption can increase the accumulation of toxins in the blood vessels, which can also lead to weight gain. In order to protect the health of the cardiovascular and cerebrovascular systems, try to quit these bad habits.

3. Adjust the diet: Unreasonable dietary patterns, especially excessive intake of high-fat foods, not only increase the burden on the body but also affect cardiovascular health. A light diet should be adopted to reduce stress on the body.

4. Increase water intake: Drinking water in moderation can help thin the blood, improve blood circulation and speed up metabolism. Developing good drinking habits can significantly reduce the risk of cardiovascular and cerebrovascular diseases.

The viscosity of blood is one of the key factors that affect the resistance of blood flow. Certain diseases can significantly slow the rate of blood flow in the microcirculation, causing blood cells to clump together and increase resistance to blood flow within the blood vessels. This can interfere with normal microcirculatory perfusion and may even lead to capillary occlusion. Therefore, we should actively take care of ourselves in our daily life, whether it is in terms of diet or lifestyle, we must cultivate good habits. Prevention is better than cure, and it is very important to abandon bad lifestyle habits as soon as possible to maintain cardiovascular and cerebrovascular health.
