Benefits of Exercise

Regular exercise brings a wide range of benefits — physical, mental, social and psychological. The main benefits are:

1. Health Benefits. Regular physical activity keeps the body healthy in several ways:

• (a) Reduces the risk of cardiovascular disease — exercise strengthens the heart and improves circulation, raising oxygen levels and helping lower the risk of high cholesterol, coronary artery disease and heart attack.
• (b) Weight management — dieting and calorie control alone are rarely effective unless combined with regular exercise.
• (c) Strengthens bones and muscles — exercise builds strong bones, slows the loss of bone density with age, and helps maintain or increase muscle mass and strength.
• (d) Reduces the risk of some cancers — including cancers of the colon, breast, uterus and lungs.
• (e) Reduces the risk of falls — for older adults, balance and muscle-strengthening work alongside moderate aerobic activity lowers the risk of falling.

2. Provides Stress Relief. Modern, competitive lifestyles create stress, whose effects include lowered immunity, low energy, poor sleep, headaches, weight gain, anxiety and depression; regular exercise helps counter these.

3. Increases Happiness. During exercise the body releases more endorphins, which produce positive feelings, lift mood and leave a person feeling relaxed and happy.

4. Promotes Self-Efficacy. Self-efficacy is the belief that one can achieve a specific goal. Regular exercise and sport strengthen a person's belief in their ability to complete physical tasks and reach challenging outcomes.

5. Promotes Social Cohesion. Group exercise and sport give people a chance to socialise, prevent boredom and isolation, and build group cohesion — a strong reason to keep exercising.

6. Enhances Value Orientation. Understanding a healthy lifestyle creates values that support starting and continuing exercise, such as discipline, better learning, self-actualisation, social responsibility and ecological awareness.

7. Cognitive Benefits. Regular aerobic activity improves attention and the speed of information processing, boosts blood and oxygen flow to the brain, and can stimulate the growth of brain cells:

• (a) Attention Control — regular, moderate exercise improves attention and concentration at every age.
• (b) Improves Memory — physical activity enhances intelligence in children, delays memory loss in the elderly, and can reduce brain changes linked to Alzheimer's disease.

8. Mental Health Benefits. Even a single session of activity can lift mood and boost the feel-good factor:

• (a) Exercise as therapy for emotional disorder — an effective intervention for depression and anxiety, improving mood and self-esteem.
• (b) Fitness as a moderator of life stress — regular activity builds a positive attitude and a greater ability to cope with stress.
• (c) Runner's High — regular activity brings mental alertness, mood upliftment, a feeling of liberation and heightened well-being.

9. Psychological Well-being. Regular activity improves blood flow to the brain, raises oxygen consumption, reduces muscular tension and improves metabolism, creating an overall feeling of wellbeing. …
