Regular exercise is good for heart health. Possible benefits include:
- improving cholesterol levels
- lowering blood pressure
- reducing the risk of heart attacks and heart disease
- reducing the risk of stroke
Reducing the risk of cardiovascular disease is an important benefit of exercise.
A person can begin experiencing the benefits of regular exercise right awayTrusted Source, though the CDCTrusted Source recommend that adults perform 150 minutes a week of at least moderate intensity activity.
The benefits continue to increase as people are more active than this.
2. Helps with diabetes management
According to the American Diabetes Association (ADA), different types of exercise can benefit people with, or at risk of, type 2 diabetes by:
- improving control of blood glucose
- reducing cardiovascular risk factors
- helping with weight loss
- helping with general well-being
- delaying or preventing the development of type 2 diabetes
Exercise can also benefit people with type 1 diabetes by:
- improving cardiovascular fitness
- strengthening muscles
- improving insulin sensitivity
The ADA say, “Physical activity and exercise should be recommended and prescribed to all individuals with diabetes as part of management of glycemic control and overall health.”
3. Reduces risk of some cancers
The National Cancer InstituteTrusted Source say there is “strong evidence that higher levels of physical activity are linked to lower risk” of the following cancers:
- colon
- stomach
- esophageal
- breast
- bladder
- uterine (endometrial)
- kidney
For example, a 2016 analysis of 26 breast, prostate, and colorectal cancer studies found a 37% reduction in cancer-specific mortality when comparing the most active patients with the least active.
There may also be a link between physical activity and reduced risk of other cancersTrusted Source, but the evidence is less clear.
4. Improves mental health and mood
Physical activity can help reduce anxiety, and this benefit can start right afterTrusted Source a moderate or vigorous exercise session.
Longer term, regular exercise can also help reduce the risk of depression.
5. Improves bone health
Regular exercise can help prevent the bone density loss that occurs with aging, say the CDCTrusted Source.
Moderate or vigorous muscle-strengthening and aerobic exercise, as well as bone-strengthening programs, can all helpTrusted Source.
Real benefits to bone density begin with only about 90 minutesTrusted Source of exercise a week.
Weight-bearing exercises, such as walking and dancing, and resistance exercises are particularly good for bone health.
6. Helps build and strengthen muscles
Weight-bearing exercise helps build strong muscles, which is particularly importantTrusted Source for adults as they get older.
7.Increases chance of living longer
“Strong scientific evidence shows that physical activity delays death from all causes,” according to a 2018 report from the Department of Health and Human ServicesTrusted Source.
Even better, the benefits start to accumulate with modest amounts of moderate-to-vigorous exercise. The greatest jump occurs when a person goes from being “inactive” to being “insufficiently active.”
8. Helps with sleep
Exercise helps people sleepTrusted Source, and some of the benefits can start immediately. Regular exercise can help by:
- increasing the efficiency of sleep
- improving sleep quality and deep sleep
- reducing daytime drowsiness
- reducing the need for sleep medication
9. May help with chronic pain
In 2017, an overviewTrusted Source of Cochrane Reviews, which look systematically at the evidence for particular interventions, examined whether exercise and physical activity help with chronic pain in adults.
The study concluded that a definitive answer would require more research.
The authors note that although the quality of evidence was generally low, “There is some evidence of improved physical function and a variable effect on both psychological function and quality of life.”
None of the interventions appeared to cause any harm. The authors of the overview noted limited evidence regarding improvement in pain severity.
10. Helps prevents falls for older adults
According to the CDCTrusted Source, physical activity that includes more than one type, such as aerobic exercise, balance training, or muscle strengthening, can help decrease both the risk of falls and the risk of injury from falls in older adults.
