Exercise is fundamental and here are some reasons why –
Exercise increases blood flow, delivering more oxygen to you brain. People who ran only 2 three minute sprints with a 2 minute break between them learned new words 20% faster than those who rested. It also spurs new growth in areas of the brain which control multitasking, planning and memory. Add a bout of exercise before trying to memorize anything.
Healthy adults who did aerobic exercise consistently were found to have 25% less pain and stiffness in the back, neck, knees and shoulders than those who did not. Exercise releases endorphins (natural pain relievers). It also appears to make us less vulnerable to tiny tears in the muscles and tendons. It can provide 25% relief from pain and stiffness even for sufferers of chronic conditions such as arthritis if done for 6 months with low impact.
Exercise helps us think more clearly, get more done and interact in a more positive way with others. Better health from exercise (even once or twice weekly) means about half the sick leave required by those who are sedentary. It is no wonder that the work place often provides a gym for its employees.
Exercise helps sexual intimacy. It can make for a better body image and also increases blood flow to the genitals. This is so even for those aged 60 or more.
Adults who did moderate 30 minute exercise, 5 or more times a week, were found to be 49% less likely to suffer peridontis (a gum disease more likely as we age). This may be do to a lowering of inflammation-causing, C-reactive protein in the blood (which also fights heart disease).
Exercise strengthens you immune system. But be cautious! More than 90 minutes of vigorous exercise (such as running daily) appears to weaken the immune system.
Women (aged 60 and more) who walked or danced at least an hour, 4 times a week, slept better. They awakened less often, averaged 48 minutes more sleep per night, and had that all-important deeper sleep often lacking in older people. This article suggests that we exercise moderately for about 30 minutes, even after a long day. For most people this will not disturb sleep and will likely benefit it.
Mild exercise clears gas and bloating. This is because increasing the heart rate and breathing stimulates the contractions of the intestinal track, helps prevent constipation and gas aids digestion.
Exercise helps cut your risk of age-related macular degeneration by up to 70%. Macular degeneration not only impairs eye sight but is the most common cause of blindness in people over age 60. However, if you are walking outside in the sun (all year around), remember to wear sunglasses which block UVA and UVB rays.
If you are fatigued, exercise. Exercise increases fatigue-fighting brain chemicals such as norepinephrine and dopamine. Also it increases the mood enhancer, seratonin.
Before engaging in exercise, please consult your doctor. I only pass on what I have read and am not a doctor. I especially hope you will turn first and foremost to The Great Physician.
