Physical activity and exercise
Physical activity and exercise is a major contributor to a healthy lifestyle; people are made to use their bodies, and disuse leads to unhealthy living. Unhealthy living may manifest itself in obesity, weakness, lack of endurance, and overall poor health that may foster disease development.
- Regular exercise can prevent and reverse age-related decreases in muscle mass and strength, improve balance, flexibility, and endurance, and decrease the risk of falls in the elderly. Regular exercise can help prevent coronary heart disease, stroke, diabetes, obesity, and high blood pressure. Regular, weight-bearing exercise can also help prevent osteoporosis by building bone strength.
- Regular exercise can help chronic arthritis sufferers improve their capacity to perform daily activities such as driving, climbing stairs, and opening jars.
- Regular exercise can help increase self-esteem and self-confidence, decrease stress and anxiety, enhance mood, and improve general mental health.
- Regular exercise can help control weight gain and in some people cause loss of fat.
- Thirty minutes of modest exercise (walking is OK) at least three to five days a week is recommended, but the greatest health benefits come from exercising most days of the week.
- Exercise can be broken up into smaller 10-minute sessions.
- Start slowly and progress gradually to avoid injury or excessive soreness or fatigue. Over time, build up to 30 to 60 minutes of moderate to vigorous exercise every day.
- People are never too old to start exercising. Even frail, elderly individuals (70-90 years of age) can improve their strength and balance with exercise.
- Almost any type of exercise (resistance, water aerobics, walking, swimming, weights, yoga, and many others) is helpful for everybody.
- Children need exercise; play outside of the home is a good beginning.
- Sports for children may provide excellent opportunities for exercise, but care must be taken not to overdo certain exercises (for example, throwing too many pitches in baseball may harm a joint like the elbow or shoulder).
- Exertion during strenuous exercise may make a person tired and sore, but if pain occurs, stop the exercise until the pain source is discovered; the person may need to seek medical help and advice about continuation of such exercise.
Most individuals can begin moderate exercise, such as walking, without a medical examination. The following people, however, should consult a doctor before beginning more vigorous exercise:
- Men over age 40 or women over age 50
- Individuals with heart or lung disease, asthma, arthritis, or osteoporosis
- Individuals who experience chest pressure or pain with exertion, or who develop fatigue or shortness of breath easily
- Individuals with conditions that increase their risks of developing coronary heart disease, such as high blood pressure, diabetes, cigarette smoking, high blood cholesterol, or having family members who had early onset heart attacks and coronary heart disease
- Individuals who are morbidly obese
Consequences of physical inactivity and lack of exercise:
- Physical inactivity and lack of exercise are associated with heart disease and some cancers.
- Physical inactivity and lack of exercise are associated with type II diabetes mellitus (also known as maturity or adult-onset, non-insulin-dependent diabetes).
- Physical inactivity and lack of exercise contribute to weight gain.
Healthy living involves more than physical health, it also includes emotional or mental health. The following are some ways people can support their mental health and well-being.
- Get enough sleep daily; the CDC recommends the following by age group (naps inclusive); 12-18 hours from birth to 2 months, 14-15 hours from 3-11 months of age, 12-18 hours for 1-3 years of age, 11-13 hours for 3-5 years of age, 10-11 hours for 5-10 years of age, eight and a half to nine and a half hours for 10-17 years of age and those 18 and above need seven to nine hours of sleep. Elderly people need about seven to nine hours but do not sleep as deeply and may awaken at night or wake early, so naps (like kids need) allow them to accumulate the total of seven to nine hours of sleep.
- Take a walk and reflect on what you see and hear at least several times per week.
- Try something new and often (eat a new food, try a different route to work, go to a new museum display).
- Do some mind exercises (read, do a puzzle occasionally during the week).
- Try to focus on a process intensely and complete a segment of it over one to several hours, then take a break and do something relaxing (walk, exercise, short nap).
- Plan to spend some time talking with other people about different subjects.
- Try to make some leisure time to do some things that interest you every week (hobby, sport).
- Learn ways to say "no" when something occurs that you do not want to do or be involved with.
- Have fun (go on a trip with someone you love, go shopping, go fishing; do not let vacation time slip away).
- Let yourself be pleased with your achievements, both big and small (develop contentment).
- Have a network of friends; those with strong social support systems lead healthier lives.
- Seek help and advice early if you feel depressed, have suicidal thoughts, or consider harming yourself or others.
- People taking medicine for mental-health problems should not stop taking these medications, no matter how "well" they feel, until they have discussed their situation with their prescribing doctor(s).
Avoidance behavior is another key to healthy living. Below are described some of the major items to avoid if a person is seeking a healthy lifestyle.
