Lack of Exercise - Effects on Three Areas of Health
It's not breaking news to hear that exercise is essential for maintaining a healthy heart and managing weight loss, but lack of exercise effects are evident on our hormones, energy levels and digestion. That's three more reasons to find a type of exercise you can enjoy three to five times a week to ensure a long and healthy life.
The American Heart Association recommends that whatever your age you should be aiming for 30 minutes of brisk walking, swimming, cycling, dancing or exercise to stay strong, fit and healthy. Here are some less well known facts about the lack of exercise effects on our overall health.
Lack of Exercise Effects on Hormones
Hormones are chemical messengers produced by the body. They affect almost every physical and mental function. Hormones control a vast array of functions in the body and mind, including:
- Growth hormones stimulate protein synthesis to build muscles and strengthen bones
- Endorphins block pain and control appetite
- Testosterone controls metabolism, sexuality and libido
- Estrogen increases fat breakdown, controls mood and libido
- Thyroxin (T4) manages energy levels
- Epinephrine directs and controls blood flow
- Insulin controls blood glucose levels and fat production
- Glucagon raises blood sugars and breaks down fat for fuel
All these hormones are secreted during exercise to keep the entire body functioning as nature intended. Lack of exercise effects on hormones means reduced triggers that stimulate the all-important hormone production throughout the body. How is your hormone health?
Fitness Fights Fatigue
Exercise does not actually lower energy levels, conversely it increases them. Studies on poor energy levels in children were undertaken by Dr. Karen Heath from the University of Cape Town Research Unit for Exercise Science and Sports Medicine. She reports that causes of lethargy in children could simply be a lack of exercise.
Regular exercise increases the red blood cells that carry oxygen to the cells. Exercise increases blood flow and the demand for cell energy. Conversely, lack of exercise means naturally low energy levels. Exercise also increases glucose circulation, making use of blood sugar and avoiding the possibility of hypoglycemia and insulin spikes. Exercise also builds muscle so the effects of lack of exercise include lean muscle mass and a lack of energy. Exercise fights fatigue and low energy in many surprising ways.
Lack of Exercise Effects on Digestive Health
If you have a sluggish digestive system, you probably suffer from irregular bowel movements and constipation. Exercise helps by raising the body's metabolic rate, pushing food through the digestive system faster so that it retains some of the water in the stool. Regular exercise helps to stimulate peristalsis, which stimulates health bowel movements, thereby reducing constipation and toxic overload.
Lack of exercise effects also means a slower heart beat and breathing rate. This fails to stimulate the intestinal muscles which contract to evacuate the bowels efficiently and frequently.
As Harvard School of Public Health researcher I-Min Lee, ScD reports, "Physical inactivity has a large impact on the health of the world…comparable to that of cigarette smoking." By adding regular physical activity to your life you will be in better shape in terms of hormone production, energy and digestion. Isn't that worth the effort?
