-One of the pervasive messages from health care providers and the media alike is that being fit is the same as being healthy, but this is not true. The premature death of top athletes including Arthur Ashe, who died from [[home:diseases:hiv_and_aids|AIDS]], Reggie White, due to [[home:diseases:sarcoidosis|sarcoidosis]], and Dale Oen [[http://nz.sports.yahoo.com/news/article/-/13934255/norwegian-swim-champ-dale-oen-died-of-heart-disease-official/|who died of atherosclerosis]], are illustrations of that. Health is the absence of disease, while fitness is a level of physical endurance. One can be healthy but not fit, but one probably cannot be fit without being healthy. The severity of one's disease limits one's level of fitness, and exercising beyond that point may be detrimental. As a result, one's fitness level decreases over the years as the severity of disease increases.+One of the pervasive messages from health care providers and the media alike is that being fit is the same as being healthy, but this is not true.

 Some patients with chronic illness have been blamed for being sick because they did not exercise enough, ate the wrong food, or partook of certain vices. However, the root cause of the problem for many was microbes, not behavior. Fitness cannot cure chronic infection.  Some patients with chronic illness have been blamed for being sick because they did not exercise enough, ate the wrong food, or partook of certain vices.

 <blockquote>Of all immune cells, natural killer (NK) cells, neutrophils and macrophages (of the innate immune system) exhibit the greatest changes in response to marathon competition, both in terms of numbers and function. Many mechanisms appear to be involved, including exercise-induced changes in stress hormone and cytokine concentrations, body temperature changes, increases in blood flow and dehydration. During this "open window" of immune dysfunction (which may last between 3 and 72 hours, depending on the immune measure), viruses and bacteria may gain a foothold, increasing the risk of subclinical and clinical infection. <blockquote>Of all immune cells, natural killer (NK) cells, neutrophils and macrophages (of the innate immune system) exhibit the greatest changes in response to marathon competition, both in terms of numbers and function.

-In a study of male recreational long-distance runners who had just participated in a marathon, researchers showed that apoptosis (the natural programmed death of cells) diminishes in the aftermath of strenuous exercise. Researchers pointed to post-race shift in the expression of key pro- and anti-apoptotic genes as playing a role in this change.(({{pubmed>long:20462402}}))+In a study of male recreational long-distance runners who had just participated in a marathon, researchers showed that apoptosis (the natural programmed death of cells) diminishes in the aftermath of strenuous exercise.

-During excessive exertion, the body manufactures cortisol (the endogenous equivalent of Prednisone), endorphins, and a series of other metabolites which might cause one to temporarily feel better, but which do little to improve long-term health. In addition, this increase in cortisol and endorphin production can suppress the operation of the innate immune response.(({{pubmed>long:9134882}}))+During excessive exertion, the body manufactures cortisol (the endogenous equivalent of Prednisone), endorphins, and a series of other metabolites which might cause one to temporarily feel better, but which do little to improve long-term health.

-This may explain the existence of exercise addiction or dependence. Exercise addiction has many symptoms in common and also shows a high comorbidity with anxiety and eating disorders,(({{pubmed>long:18956613}})) (({{pubmed>long:15208508}})) both of which are known Th1 diseases.+This may explain the existence of exercise addiction or dependence.

-In addition to cortisol, adrenaline (also known as epinephrine) is secreted by the body during physical exertion. //E. coli// also produces epinephrine for communication with other members of the species in a process known as quorum sensing.(({{pubmed>long:12847292}})) (This may be because pathogens are able to more effectively communicate and spread during times when the body is weakened.)

-There is strong and consistent evidence that a single exercise session can reduce triglycerides and increase high-density lipoprotein (HDL) cholesterol (HDL-C), reduce blood pressure, and improve insulin sensitivity and glucose homeostasis.(({{pubmed>long:11427768}})) There is also evidence that regular exercise reduces the risk of atherosclerosis and cardiovascular diseases among others.+There is strong and consistent evidence that a single exercise session can reduce triglycerides and increase high-density lipoprotein (HDL) cholesterol (HDL-C), reduce blood pressure, and improve insulin sensitivity and glucose homeostasis.(({{pmid>long:11427768}})) There is also evidence that regular exercise reduces the risk of atherosclerosis and cardiovascular diseases among others.
  
-One possibility worth researching in greater depth is how long-term improvement from exercise is due to the effect raised body temperature has on immune function. Fever, the natural increase in one's body temperature, has been conserved during evolution through millennia, because of its advantage for host defense.(({{pubmed>long:16613288}})) Important immunological reactions are sped up by temperature, and some pathogens with strict temperature preferences are hindered.(({{pubmed>long:9289813}}))+One possibility worth researching in greater depth is how long-term improvement from exercise is due to the effect raised body temperature has on immune function.

 It seems likely that the "self-induced fever" resulting from sustained (and moderate) exercise plays a role in helping the body to kill some of the microbes which cause disease. It seems likely that the "self-induced fever" resulting from sustained (and moderate) exercise plays a role in helping the body to kill some of the microbes which cause disease.

 Aerobic exercise,if done correctly, will enable you to create energy from fat and oxygen, lessening lactic acid build up. Finally, stretching should never be painful. Most people either don't stretch or stretch too vigorously, causing strain. Aerobic exercise,if done correctly, will enable you to create energy from fat and oxygen, lessening lactic acid build up.

 ===== Tips for improving mobility ===== ===== Tips for improving mobility =====
  
-  * When symptoms limit your activities, try not to stay in bed all of the time. Prolonged bed rest puts you at risk for blood clots, pneumonia, skin breakdown and muscle deterioration. Change positions in bed, use a recliner or sofa for part of the day and walk as far as you are able to at regular intervals. Do gentle stretching and motion [[http://www.orthop.washington.edu/?q=patient-care/articles/arthritis/exercise-and-arthritis.html|exercises]],  [[http://www.orthop.washington.edu/?q=patient-care/articles/arthritis/water-exercises.html|water exercise]] to maintain some flexibility and strength.  +  * When symptoms limit your activities, try not to stay in bed all of the time.

-  * If your mobility is compromised, be sure you are safe when you move around. Ask for help, safety proof your home to prevent falls and equip your home with [[http://arthritis.about.com/od/assistivedevicesgadgets/Arthritis_Aids_Gadgets_Products_Tools_Adaptive_Equipment.htm|safety devices and aids]] for independent living.+  * If your mobility is compromised, be sure you are safe when you move around.

   * Community or social services may provide a shower chair and rails and a toilet seat with extra height to increase your safety. A recliner chair and an ordinary bed can be made the right height with help. Some find a bed stick useful for getting and sitting up.   * Community or social services may provide a shower chair and rails and a toilet seat with extra height to increase your safety.

   * If you have a hospital bed, ensure that it is at a safe height for you. For your ease in getting out of bed, it should be set so that you do not have to lift yourself up; when you get back into bed it should be lowered for ease of sitting down.   * If you have a hospital bed, ensure that it is at a safe height for you.

One 2011 study found plasma concentration of microparticles from platelets and polymorphonuclear neutrophils (PMN) was increased immediately after the strenuous exercise.(({{pubmed>long:21321404}}))+Strenuous exercise is associated with an inflammatory response involving a range of cell types.
