1 What is blood pressure?
Blood pressure is the pressure the blood exerts on the walls of the arteries, this pressure helps bring blood to nourish the parts of the body.
Blood pressure is measured by systolic blood pressure (the highest level of blood pressure in a blood vessel, which occurs when the heart contracts) and diastolic blood pressure (the lowest level of blood pressure in a blood vessel which occurs between heart contractions). squeeze, when the heart muscle is relaxed).
The unit of measurement of blood pressure is in mmHg. Blood pressure in humans is measured in the brachial artery, which is the inside of the hand at the elbow.
2 What is a normal blood pressure reading?
Prehypertension is the value of blood pressure readings between normal and high blood pressure (systolic blood pressure 120-139 mmHg or diastolic blood pressure 80-89 mmHg ).
High blood pressure: When the systolic blood pressure is greater than 140 mmHg and the diastolic blood pressure is greater than 90 mmHg, it is diagnosed as high blood pressure.
Low blood pressure: Hypotension (low blood pressure) is diagnosed when systolic blood pressure is less than 90 mmHg or 25 mmHg lower than normal.
Below is a list of normal blood pressure readings by age:
3 Factors affecting blood pressure
Elements inside the body
Cardiac contractility: The force of contraction of the heart greatly affects blood pressure. Because the stronger the heart contracts, the faster it beats, and the greater the pressure of blood on the artery walls. When the heart beats fast due to vigorous exercise or emotional nervousness. Excitement will cause blood pressure to rise higher than normal.
Arterial resistance: Arteries are the place where blood circulates to nourish cells. Therefore, if the arteries have good elasticity, there is not much obstruction, the blood will move more easily, then the blood pressure will be stable.
In the case of atherosclerosis (which often occurs in the elderly), the vessel walls are less elastic, making it difficult for blood to move. The resistance of the artery walls to the blood will increase, causing the blood pressure to rise.
Blood volume: Low blood volume will lead to low blood pressure because there is not enough blood to put pressure on the artery walls.
This condition occurs when each person loses too much blood, and blood pressure will drops, which is life-threatening when there is not enough blood to carry around the body.
Factors outside the body
Sitting posture : Sitting posture also determines blood pressure, you should practice sitting with a straight back and shoulders because this will help blood easily circulate from the heart to the organs in the body. Since then, your blood pressure is always at a stable level.
Diet and activities: Habits of eating a lot of animal fat and salty foods, and using stimulants such as alcohol, coffee, etc. will cause diseases such as hardening of the artery walls, or fatty blood.
A scientific lifestyle will also help prevent blood pressure diseases. You should exercise for at least 30 minutes every day. For beginners, pay attention to increasing the intensity every day. However, do not exercise too much.
4 ways to help stabilize blood pressure
Eat sensibly: Limit salty eating habits, and do not use more than 6g of sodium salt a day. To prevent blood pressure diseases, it is advisable to have a reasonable diet such as: increasing the diet containing a lot of potassium and calcium such as vegetables, nuts, milk, etc.
Limit the use of stimulants: According to many studies, Alcohol and stimulants also affect the cardiovascular system and blood pressure. Men should not drink more than 30 grams, women should not drink more than 20 grams of alcohol per day.
Exercise regularly: Regular exercise helps reduce heat absorption and lower blood pressure. Every day should spend 30-45 minutes practicing light sports.
Walking, jogging, cycling, other active games, etc. are forms of exercise you should try. Note that before and after a workout, it is recommended to relax for 5 minutes.
Psychological balance: The state of sadness or anxiety, and pessimism also affects the heart, and easily increases blood pressure. Therefore, have a healthy, happy lifestyle.
Don’t overwork, don’t let yourself get too stressed. It is necessary to combine work, study, and rest in a scientific and reasonable manner.
Using a blood pressure monitor to monitor your blood pressure at home: will help you keep a close eye on your blood pressure readings. Therefore, equipping this health equipment becomes especially necessary.
