So to the question, does exercise promote general health? 

 

The simple answer is, yes, it does. 

 

 

What exercise is?

Exercise is a deliberate, repetitive, and well-planned movement that's aimed to maintain or enhance physical and mental health. Regular exercise is one of the most important routines you can do for your health. So, whether you're going for a walk, hitting the gym, or trying a new fitness class, making exercise a regular part of your routine can have a significant impact on your overall health and well-being.

 

Exercising not only helps you build muscles and burn calories to lose weight, but it also promotes better physical and mental wellness. When you exercise, your body releases endorphins which are natural chemicals that make you feel happy and reduce feelings of anxiety and depression.

 

Physical inactivity is related (directly and indirectly) to the other leading risk factors for noncommunicable Diseases(NCDs) such as high blood pressure, high cholesterol, and high glucose levels; and, to the recent striking increases in childhood and adult obesity, not only in developed countries but also many developing countries, says, Professor Karim Khan, MBBS, Ph.D., MBA, FACSP, a sports physician and editor of the British Journal of Sports Medicine.

 

"Physical activity has comprehensive health benefits across the lifespan: It promotes healthy growth and development in children and young people, helps to prevent unhealthy midlife weight gain, and is important for healthy aging, improving and maintaining the quality of life and independence in older adults", he explains. 

 

 

Benefits of regular exercise to general health

 

1. Improves Heart Health 

Engaging in regular physical activity strengthens your heart muscle and increases the efficiency of your heart's ability to pump blood around your body, reducing the stress on your heart. 

Participating in regular, moderate-intensity exercise can reduce your risk of cardiovascular disease, stroke, and diabetes. Incorporating physical exercise into your everyday life can have a great impact on your health and help extend your life. 

 

2. Improves immune system 

It is important to stay physically active to keep your immune system robust and healthy. Regular exercise can help your body combat illnesses and infections more efficiently. Exercise also helps boost the production of natural antibodies and white blood cells, which help your body fight off harmful infective agents.

Exercise is one of the most important ways to keep your immune system functioning optimally. Make sure to get regular exercise as it helps reduce stress hormones, which can weaken your immune system. 

 

3. Improves mental health and mood

Regular exercise is an effective way to enhance your mental well-being and mood. It can reduce stress, aid concentration and focus, raise your self-esteem (self-worth) and confidence, and be a way to diffuse anger and frustration. Additionally, it can lessen symptoms of depression and anxiety and make you more resistant to stress and other mental health issues.

Exercise increases your endorphin levels, which are your body's natural happy hormones. This helps relax you and promotes better sleep. It also has a positive effect on your well-being and helps reduce stress, tension, and negative thoughts. Regular exercise can help keep your mind sharp, so to burn calories and improve your mental health and mood, ensure to include your exercise routine in your daily activities. 

 

4. Improves joint mobility and strength

Exercising regularly can help keep your joints flexible and supple, lowering the chance of injuring or straining them. Additionally, strength training exercises can bolster joint stability, enhance your range of motion, and minimize your risk of developing arthritis.

Exercise offers many benefits, including reducing inflammation and protecting your joints from further damage and discomfort. Exercise also strengthens the muscles around your joints, providing valuable support and protection. For these reasons, exercising is essential for keeping your joints healthy and supporting your overall health.

 

5. Improves physical strength and endurance

Regular exercise has multiple positive benefits for your physical health. It can help you lose weight, build muscle, and improve your endurance and stamina. Working out regularly can make your body stronger, more flexible, and better able to withstand physical exertion. 

Exercise also increases your energy level, allowing you to be more productive and efficient throughout the day. So, if you want to be healthier and more active, incorporate regular exercise into your daily routine. You'll benefit from improved physical and mental endurance and have a better quality of life.

 

6. Improves brain function and memory

Exercise is one of the most effective ways to improve brain function and memory. Many scientific studies have shown that regular physical activity can improve cognitive performance and memory and even help protect the brain from age-related decline. 

According to a study, exercise boosts blood flow to the brain, allowing it to receive more oxygen.¹ This oxygenation increases the production of hormones linked to better cognitive skills and memory. It also encourages the creation of new brain cells, which aids in memory formation. To increase your brain's function and memory, incorporate regular exercise routines into your daily activities.

 

7. Improves sleep 

Physical activity during the day helps you fall asleep faster and stay asleep longer at bedtime. Exercise lengthens the time spent in deep sleep, which is the most restorative stage. Additionally, exercise releases endorphins and hormones that help you relax and regulate your body's natural sleep patterns. 

According to the Sleep Foundation, people who get regular exercise have fewer sleep disturbances overall and improved mental and physical health.² Exercise is not only beneficial for good sleep but also for overall health and well-being. So get up, get moving, and start experiencing the benefits of exercise for better sleep.

 

8. Reduces your risk of chronic diseases

Not only does it have physical benefits such as increased strength and flexibility, but it can also have a profound impact on reducing your risk of chronic diseases such as diabetes, heart disease, and stroke. Studies have found that regular physical activity can help lower cholesterol and blood pressure and even reduce your risk of certain types of cancer.

With so many benefits, there is no reason why you shouldn't make regular exercise a part of your lifestyle. A workout is an investment in your health, so start today and reap the rewards for years to come. 

 

9. Maintains body weight 

Exercise is an essential part of maintaining healthy body weight. Regular physical activity helps to improve overall health by increasing the body's use of nutrients, helping you to flush waste from your body, and improving circulation. Additionally, working out helps burn calories, which in turn helps reduce overall body weight. 

Exercise is the most important factor in managing your body weight. Aerobic activities such as walking, running, swimming, and cycling are especially effective at burning calories and supporting weight loss. Strength-training exercises can also help build muscle and enhance your metabolism, which helps you burn more calories.

 

 

How exercise can help you to prevent certain diseases 

There are numerous benefits of exercise for general health and wellbeing.

Regular physical activity has been linked to a lower risk of many chronic diseases, including heart disease, stroke, type 2 diabetes, and certain types of cancer. 

Physical activity helps to control weight, reduce fat, and build or maintain muscle mass and strength. It also helps to reduce stress, improve mood, and boost energy. Workouts can also help to reduce the risk of certain diseases, such as coronary heart disease, stroke, type 2 diabetes, and certain types of cancer. Regular physical activity can also help to improve overall health and even reduce the risk of premature death. 

The amount and type of activity recommended to prevent disease depends on the person’s age, weight, and other factors. According to the American Heart Association recommendation, adults should get at least 150 minutes of moderate-intensity aerobic activity every week.³  Walking, jogging, swimming, cycling, and engaging in sports are examples of this. Strength-training exercises should also be done at least two days a week.
