High Blood Pressure and Exercise: Explaining the Effects of Exercise on Lowering Blood Pressure and Recommended Habits

Why exercise is effective in improving high blood pressure

Exercise is effective in improving high blood pressure because there is a close relationship between physical activity and blood pressure.
Making exercise a habit improves the body's mechanisms for controlling blood pressure in many ways.

Specifically, improving blood vessel function and balancing the autonomic nervous system makes it easier to maintain stable blood pressure.
In addition, secondary effects such as reducing obesity also contribute greatly to normalizing blood pressure.

The mechanism behind exercise lowering blood pressure

When you continue to exercise, various mechanisms are activated in your body to lower your blood pressure.
Blood pressure temporarily rises during exercise, but by doing it regularly, endothelial function improves, making blood vessels more likely to dilate, which ultimately lowers blood pressure.

Additionally, sweating during exercise helps expel excess salt and water from the body.
Additionally, regular exercise improves cardiovascular fitness, allowing the heart to pump more blood at one time, slowing down heart rate and stabilizing blood pressure in the long term.
Another factor that lowers blood pressure is that the autonomic nervous system is balanced and excessive blood vessel constriction is suppressed.

It also helps prevent lifestyle-related diseases such as obesity.

Exercise has many benefits beyond just reducing high blood pressure.
Regular exercise increases energy consumption and is directly linked to the elimination and prevention of obesity.
Obesity is a major risk factor for hypertension, so maintaining proper weight control is very important.
Exercise also helps stabilize blood sugar levels by increasing insulin sensitivity, which can help prevent and improve diabetes.

It also has the effect of reducing neutral fats in the blood and increasing good cholesterol, making it effective in preventing dyslipidemia.
In this way, exercise simultaneously reduces the risk of multiple lifestyle-related diseases.

Recommended exercise menu for improving high blood pressure

There are several types of exercise to improve high blood pressure, each with its own characteristics.
The important thing is to choose exercise that has a low risk of raising your blood pressure suddenly and is easy to continue.
The basic exercise suitable for people with high blood pressure is aerobic exercise, which promotes blood circulation throughout the body.

In addition, you can expect even better results by combining it with light strength training and stretching.
Here we will introduce recommended exercise menus for people with high blood pressure and how to do each.

Aerobic exercise such as walking or swimming

The key to improving high blood pressure is aerobic exercise, which involves rhythmic movement and continuous mild exertion.
Typical examples include walking, light jogging, water walking or swimming, cycling, and ballroom dancing.
Walking in particular is recommended because it does not require any special equipment or space and anyone can easily start.

Swimming is also suitable for people who are concerned about their weight or joints, as the buoyancy of water puts less strain on the knees and hips.
These exercises improve the function of the heart and lungs and improve blood flow throughout the body, contributing to long-term blood pressure stability.

Light strength training such as squats

Combining light strength training (resistance exercise) with aerobic exercise is also effective in improving blood pressure.
Increasing muscle mass improves your basal metabolic rate and helps you lose weight.
Squats, push-ups, and sit-ups can be done at home without any equipment and are easy to do.

When doing strength training, it is important to keep breathing naturally and move slowly.
Avoid anaerobic exercise, such as holding your breath, and isometric exercise, which involves exerting yourself still, as these can cause your blood pressure to rise sharply.
The key is to do it with a light load.

Stretching to relax the body and mind

Stretching is essential as a warm-up and cool-down exercise before and after exercise.
It improves muscle flexibility, increases blood circulation and helps prevent injuries.

In addition, stretching while focusing on deep breathing has the effect of activating the parasympathetic nervous system and relaxing the mind and body.
This is expected to help alleviate the rise in blood pressure caused by stress.
No special equipment is needed; simple movements like stretching your leg muscles while sitting in a chair, gently twisting your upper body, and stretching your sides are enough.
It can be easily incorporated into your daily life.

Four points to effectively perform exercise to lower blood pressure

When exercising to lower your blood pressure, it is more effective to keep a few points in mind rather than just moving your body blindly.
It is important to consider "exercise prescription," which involves appropriately setting not only the type of exercise but also factors such as frequency, time, and intensity.

In addition, to continue exercising safely, it is essential to take care of yourself before and after exercise.
Here we will explain four specific points to help you maximize the benefits of exercise and continue it safely.

Tip 1: Exercise at least three days a week

The blood pressure lowering effect of exercise lasts for about 1 to 2 days after exercise, but is not permanent.
Therefore, you need to continue exercising regularly to maintain the benefits.
High blood pressure guidelines recommend regular exercise, preferably every day, but aiming for at least three days a week is a good starting point.

It is more effective to do it every other day or so without leaving any gaps in between, rather than doing it for a long time all at once on the weekend.
Rather than forcing yourself to do it every day, it's important to find a frequency that suits your lifestyle and that you can steadily maintain.

Point 2: Aim for at least 30 minutes of exercise per session

To get the most out of aerobic exercise, it is recommended that you continue for at least 30 minutes at a time.
But if you find it difficult to find time, don't give up.

It is said that if you exercise for more than 10 minutes several times a day for a total of 30 minutes or more, you can expect the same effects as if you did it continuously.
For example, you could walk 10 minutes on your morning commute, 10 minutes during your lunch break, and 10 minutes when you get home.
If you are not used to exercising, start with 10 minutes and gradually increase the time to reach your goal without straining yourself.

Point 3: Keep the intensity of your exercise to a level that feels "slightly hard"

Exercise intensity that is too high or too low is not effective.
The appropriate intensity for improving blood pressure is one that feels subjectively "slightly hard."
Specifically, you should be out of breath while exercising, but maintain a level that allows you to smile and have a conversation with the person next to you.

When managing your heart rate, a moderate load is considered to be a target heart rate of around 50-60% of your maximum heart rate (220 minus your age).
Exercising too vigorously can actually raise your blood pressure so be careful not to overdo it.
The key to continuing is to exercise at an intensity that feels comfortable and suits your physical strength.

Tip 4: Always warm up and cool down before and after exercise

To exercise safely, it is very important to take care at the beginning and end of your workout.
Before exercising, warm up for 5 to 10 minutes.
By using light stretching and foot tapping to gradually increase your heart rate and loosen your muscles and joints, you can prevent sudden strain on the heart and injury.

After exercising, you should not suddenly stop moving.
Gradually slow down your exercise pace and finish by stretching for 5 to 10 minutes to cool down.
This allows your heart rate and blood pressure, which increase during exercise, to gradually return to normal levels, reducing the risk of dizziness or fainting immediately after exercise.

Things to keep in mind when exercising if you have high blood pressure

Exercise is an effective way to improve high blood pressure, but it is not unconditionally recommended for everyone.
Especially if you have very high blood pressure or other complications such as heart disease, exercise can put a strain on your body and even put you at risk of developing a dangerous condition.
There are cases where exercise is contraindicated, so there are a few precautions you need to take in order to start exercising safely.

The general rule is not to start on your own judgment, but to proceed under the guidance of an expert.

Always consult your doctor before starting any exercise

If you are being treated for high blood pressure or have other complications such as heart disease, kidney disease, or diabetes, be sure to consult your doctor before starting any exercise program.
A comprehensive assessment will be made of factors such as your current blood pressure control status, the types of medications you are taking, and the severity of any complications, and you will need to receive guidance on whether exercise therapy is appropriate and the appropriate type and intensity of exercise.

Especially if you are taking antihypertensive medication, you should also consider the possibility that exercise may lower your blood pressure too much.
In order to proceed with exercise therapy safely, the first step is to undergo a medical check-up by a specialist.

If you are not feeling well, take a rest and don't push yourself.

It is important to continue exercising, but don't force yourself to do it on days when you're not feeling well.
If you have a fever, are sleep deprived, or feel very tired, stop exercising and prioritize resting your body.
Also, if you experience any of the following symptoms while exercising: headache, dizziness, nausea, chest pain, palpitations, or extreme shortness of breath, stop exercising immediately.

If symptoms do not improve or occur frequently, you should see a doctor immediately.
The golden rule for continuing to exercise safely is to listen to your body and never push yourself too hard.

Avoid high-intensity exercise that can cause a sudden rise in blood pressure

People with high blood pressure should avoid exercise that can cause a sudden rise in blood pressure.
Specifically, this includes high-intensity anaerobic exercise that requires instantaneous, powerful force, such as weightlifting or sprinting.

In addition, in cases of severe hypertension, such as when the systolic blood pressure is 180 mmHg or higher or the diastolic blood pressure is 110 mmHg or higher (stage III hypertension), drug therapy to lower blood pressure is given priority over exercise therapy.
Changes in temperature also affect blood pressure, so you should be careful not to exercise too much in harsh environments, such as early in the morning in winter or under the hot summer sun.

Three tips to make exercise a habit without straining yourself

To improve and prevent high blood pressure, it is necessary to make exercise a regular part of your life, rather than just a one-time event.
However, it is not easy to continue exercising in our busy lives.
The important thing is not to aim for perfection, but to find a way that works for you.

Here are three practical tips to help you enjoy exercise and continue it for a long time.

Tip 1: Increase opportunities to move your body in your daily life

If you find it difficult to find time to exercise, start by increasing your activity in your daily life.
It is effective to incorporate exercise while doing other things.
For example, small changes like getting off one stop earlier and walking when commuting, or using the stairs instead of the elevator are some examples.

Even at home, tapping your feet in place while watching TV or simply cleaning or tidying up quickly can be a great form of exercise.
This cumulative physical activity will ultimately lead to improved blood pressure.
First, try to reduce the amount of time you spend sitting and be conscious of moving your body more frequently.

Tip 2: Have fun with your family and friends

If you find it difficult to exercise alone, doing it with someone can help you stay motivated.
Another good idea is to invite family or friends to go for a walk, or join a local sports club or gym.
If you have friends, you can encourage each other and have fun working together.

By viewing exercise not just as an end in itself but also as an opportunity for communication, you will feel less obligated to do it and will naturally be able to continue.
Finding friends who share the same goals can be a great way to make exercise a habit.

Tip 3: Keep track of your blood pressure and weight to stay motivated

If you continue to exercise, you will gradually see changes in your body.
To experience the benefits, we recommend that you get into the habit of recording your blood pressure, weight, number of steps, etc. every day.
By using smartphone apps or a notebook to record your numbers, you can make your efforts visible.

When you see positive changes, such as stabilizing your blood pressure or losing weight, it can give you a boost of confidence and motivate you to keep exercising.
Keeping records is helpful for managing your health and also gives you clues as to when your blood pressure is likely to fluctuate.

Lifestyle improvement measures to be implemented in conjunction with exercise

In order to effectively improve high blood pressure, it is essential to review not only your exercise habits but also your overall lifestyle, including your diet.
In order to maximize the effects of exercise and maintain stable blood pressure, a multifaceted approach is required that addresses multiple aspects such as diet, recreational substances, and rest.

Here we will explain lifestyle improvement measures that should be implemented in parallel with exercise therapy.

A well-balanced diet with low salt content

Dietary modification, especially salt reduction, is very important in managing hypertension.
Excessive salt intake causes the body to retain water, which increases blood volume and raises blood pressure.
The Japanese Society of Hypertension recommends limiting salt intake to less than 6g per day.

Processed foods, instant foods, and restaurant meals tend to be high in salt, so it's a good idea to get into the habit of checking the ingredient labels.
When cooking, try to use the flavor of dashi stock, spices, aromatic vegetables, etc. to make food delicious even with a light flavor.
In addition, actively consuming vegetables and fruits that are high in potassium will help to excrete excess salt.

Quit smoking and reduce alcohol intake

Smoking and excessive alcohol consumption are major enemies of blood pressure control.
The nicotine contained in tobacco stimulates the sympathetic nervous system, constricting blood vessels and temporarily raising blood pressure.
Long-term smoking accelerates arteriosclerosis and significantly increases the risk of myocardial infarction and stroke.
If you are diagnosed with high blood pressure, it is highly recommended that you quit smoking.

Excessive alcohol consumption also contributes to increased blood pressure.
If you have a drinking habit, it is important to drink in moderation and take days off from drinking.
The recommended amount of alcohol is about one medium bottle of beer or one cup of sake per day.

Get enough sleep and manage stress

Lack of sleep and mental stress can disrupt the balance of the autonomic nervous system and cause blood pressure to rise.
Getting enough quality sleep is essential for mental and physical recovery and stabilizing blood pressure.
Try to go to bed and wake up at the same time every day, and especially get some morning light to help regulate your body clock.

Also, while it is difficult to completely eliminate stress in modern society, it is important to find your own way to relieve it.
Implement habits that relax your mind and body, such as taking time to pursue a hobby, spending time in nature, or talking with loved ones.

My Feelings, Then and Now

Exercise therapy is an important pillar alongside diet therapy in improving high blood pressure.
It is recommended to focus on aerobic exercise such as walking or swimming, combined with light strength training and stretching.
In addition to the direct effect of lowering blood pressure, exercise also contributes to reducing obesity and preventing other lifestyle-related diseases such as diabetes and dyslipidemia.

For effective exercise, aim to exercise at least three times a week for at least 30 minutes at a time, at an intensity that feels "slightly tough," and be sure to do warm-up and cool-down exercises before and after the exercise.
However, it is important to always consult a doctor before starting any exercise to ensure you are doing so safely.
Finally, comprehensive blood pressure control is possible by simultaneously improving your overall lifestyle, not only through exercise but also by reducing salt intake, quitting smoking, drinking less alcohol, and managing stress.
