When do the concepts of fitness and exercise not automatically go together? When you're dealing with a compromised immune system.
A Special Health Report from Harvard Health Publications advocated moderate exercise for maintenance of a healthy immune system.
But the article went on to report that Professor David Nieman, Dr. PH., of Appalachian State University would balance this with the caution that too much exercise can decrease immune function.
Overdoing exercise can produce more of the stress hormones adrenaline and cortisol which can increase cholesterol levels and blood pressure and weaken the immune system. This information was published in a February 21, 2011 article on Betterhealthjournal.com.
Nieman was specifically talking about athletes, but the individual with an already weakened or compromised immune system could be in real trouble.
According to Sportsmedicine.about.com, moderate exercise can mean fewer colds and flu. The immune system responds positively to this state of affairs as macrophages which attack toxins flourish.
Immune cells are more efficient in eliminating viruses and bacteria. This boost generally only lasts a few hours but when moderate exercise is done regularly, an overall increase in well-being can occur.
But too much of a good thing can really be too much and can lead to negative repercussions. Time to rest and recover is essential for the overtaxed immune system.
Athletes who overtrain can be more vulnerable to illness and a weakened immune system. The person who is ill, who has a chronic health condition with reduced immune function must be very careful.
If you have a weakened immune system, it may still be possible to incorporate some activity into your day. Just be sure to let your body and its responses be your guide.
Learning-tai-chi.info refers to the website WebMD, saying that when we manage stress effectively, our immune systems benefit. Tai chi targets the parasympathetic nervous system which triggers rest and regeneration.
The Free Dictionary website endorses tai chi because it enhances the cardiovascular and immune systems.
