How much do Americans spend on health care annually?
Americans spend more than $600 billion dollars annually for health care. This meteoric figure translates into an expenditure of almost $3,000 for every individual in the entire population.
Ralph Paffenbarger, MD, found that men who expended approximately 300 calories a day; the equivalent of walking briskly for 45 minutes
reduced their death rates from all causes by an extraordinary 28% and lived an average of more than two years longer than their sedentary classmates.
The higher the fitness level
the lower the death rate
Exercise is one of the body’s most efficient ways to control nasal congestion (and the accompanying discomfort of restricted nasal blood flow).
Regular aerobic exercise dilates vessels, increasing blood flow — thereby improving the body’s ability to extract oxygen from the bloodstream.
Exercise triggers the release of mood-altering chemicals in the brain.
By forcing a skeletal joint to move, exercise induces the manufacture of synovial fluid, helps to distribute it over the cartilage and forces it to circulate throughout the joint space.
Exercise helps to both strengthen the abdominal muscles and the lower back extensor muscles and stretch the hamstring muscles.
Bursitis and Tendonitis.
Exercise can strengthen the tendons — enabling them to handle greater loads without being injured.
Exercise helps maintain ideal bodyweight and helps keep body fat to a minimum.
Carpal Tunnel Syndrome.
Exercise helps build up the muscles in the wrists and forearms — thereby reducing the stress on arms, elbows and hands.
Exercise helps to raise HDL (the “good” cholesterol) levels in the blood and lower LDL (the undesirable lipoprotein) levels.
Exercise helps strengthen the abdominal muscles, thereby making it easier to pass a stool.
Exercise helps speed metabolism and deliver more oxygen to the brain;
Exercise helps lower excess blood sugar levels, strengthen muscles and heart, improve circulation, and reduce stress.
Exercise can help alleviate the fatigue-causing effects of stress, poor circulation and blood oxygenation, bad posture, and poor breathing habits.
Exercise helps relieve intraocular hypertension — the pressure buildup on the eyeball that heralds the onset of glaucoma
Exercise helps force the brain to secrete more of the body’s opiate-like, pain-dampening chemicals (e.g., endorphins and enkephalins).
Exercise helps promote many changes that collectively lower the risk of heart disease — a decrease in body fat, a decrease in LDL, an increase in the efficiency of the heart and lungs, a decrease in blood pressure and a lowered heart rate.
High Blood Pressure.
Exercise reduces the level of stress-related chemicals in the bloodstream that constrict arteries and veins, increases the release of endorphins, raises the level of HDL in the bloodstream, lowers resting heart rate (over time), improves the responsiveness of blood vessels (over time), and helps reduce blood pressure through bodyweight maintenance.
Exercise helps reduce muscular tension and stress.
Exercise helps improve peripheral circulation and increases pain tolerance.
Exercise helps strengthen the structures attendant to the knee — muscles, tendons and ligaments — thereby facilitating the ability of the knee to withstand stress.
Exercise helps strengthen the muscles associated with breathing and helps boost the oxygen level in the blood.
Exercise helps to improve cognitive ability by increasing the blood and oxygen flow to the brain.
Menstrual Problems and PMS.
Exercise helps to control the hormonal imbalances often associated with PMS by increasing the release of beta-endorphins.
Exercise promotes bone density — thereby lowering an individual’s risk of suffering a bone fracture.
Exercise is an appetite suppressant. It also increases metabolic rate, burns fat, increases lean muscle mass and improves self-esteem.
Exercise can help control the level of discomfort caused by existing varicose veins and help prevent getting any additional varicose veins.
