Is low pressure 40 normal?

The human body's blood pressure is usually maintained within a normal range, and different blood vessels have different blood pressure values. The blood pressure we often refer to is the blood pressure in the human body's arteries, which plays a role in promoting blood flow in the blood vessels. However, as people age, many of them also face symptoms related to low blood pressure or high blood pressure. So when the low blood pressure reaches 40, is it a normal phenomenon for the human body?

Normal blood pressure values ​​refer to the normal values ​​of blood pressure for different age groups, which makes it convenient for modern people to understand their blood pressure in time, detect hypertension in time, and treat it in time. Hypertension has become one of the diseases that endanger modern people.

Normal blood pressure is a prerequisite for blood circulation. Blood pressure remains normal under the regulation of multiple factors, thereby providing various tissues and organs with sufficient blood to maintain normal metabolism. Both low and high blood pressure (hypotension, hypertension) can cause serious consequences, and the disappearance of blood pressure is a precursor to death. This shows that blood pressure has extremely important biological significance.

1. Influencing factors

1. The level of blood pressure is not only closely related to heart function, vascular resistance and blood volume, but also affected by nerves, body fluids and other factors. Blood pressure values ​​will vary with age, season, climate and occupation. Exercise, eating, mood changes, bowel movements, etc. will cause blood pressure to rise, while rest and sleep will lower blood pressure.

2. Mental stimulation and emotional changes such as excitement and fear can often lead to a significant increase in systolic blood pressure. Exercise can also significantly increase systolic blood pressure, especially strenuous exercise, which often causes systolic blood pressure to rise to 24.0-6.7 kPa (180-200 mmHg). Blood pressure may drop after exercise stops. An increase in ambient temperature, such as taking a warm bath, can lower diastolic blood pressure, while a decrease in temperature, such as taking a cold bath in winter, can increase systolic blood pressure. People with high blood pressure should pay attention to their diet, as blood pressure increases as people age.

3. Hypertension is mainly caused by bad living habits, such as lack of exercise, eating too much salt, smoking, drinking, etc. Among them, eating too much salt is the main factor causing hypertension in my country. However, a bigger concern is people's negligence and lack of awareness about hypertension. About 70% of hypertensive patients are unaware that they are ill, only 14% receive treatment, and less than 10% have their blood pressure effectively controlled. Therefore, early detection and control are very important for the prevention and treatment of hypertension. Early prevention, stable treatment and a healthy lifestyle can control 75% of hypertension and its complications.

2. What to do if the low pressure is high

(I) What to do if middle-aged people have low blood pressure and high blood pressure

1. Below 95 mmHg

If the diastolic blood pressure is lower than 95 mmHg, non-drug treatment can be used, mainly focusing on improving lifestyle, including relaxing the mind and maintaining a happy mood. Maintain a regular lifestyle and balance work and rest. The diet should be light. Moderate exercise is a must.

The above methods can regulate autonomic nervous function, reduce sympathetic nerve excitability, improve vascular reactivity, promote peripheral vasodilation and lower blood pressure, especially diastolic pressure.

2. Above 95 mmHg

If the diastolic blood pressure is greater than 95 mmHg, especially if symptoms of hypertension have appeared, drug treatment should be started. It is recommended that under the guidance of a specialist, antihypertensive drugs, captopril tablets, aspirin sustained-release tablets, and salvia miltiorrhiza tablets should be reasonably arranged according to the condition of the patient and taken regularly.

Eat a low-fat, low-salt diet, avoid eating animal offal, and eat more vegetables such as potatoes, eggplants, kelp, lettuce, etc.

Appropriate exercise such as walking, Tai Chi, etc. is very helpful in lowering diastolic blood pressure.

More massage, kneading Fengchi, Taiyang and ear points, wiping the forehead and pinching Neiguan, Shenmen, Hegu and Zusanli can help lower blood pressure and eliminate symptoms.
