Is It OK To Exercise When Sick?
From WikiBody - The Owner's Manual For Your Body
It depends on:
- how sick you are
- and how hard you exercise.
[edit] If You Have Mild Cold Symptoms
If you have mild cold symptoms, such as:
- runny nose
- sneezing
- scratchy throat
It's OK to work out moderately. Moderate exercise means 40 minutes of aerobic activity at 70% or less than your maximum heart rate. If you lift weights, lift 75% of your normal weight and don't exercise to failure. Moderate exercise can even make you feel better by clearing up your nasal passages. This rule is commonly known as the "neck check" -- if your sickness is "above the neck", it's OK to exercise. Finally, exercise your own common sense. Pay attention to how you feel 5-10 minutes after you begin exercising. If you feel good, keep going. If you're feeling worse, stop immediately.
[edit] If You Have Severe Symptoms
If you have more severe symptoms, such as:
- fever
- dry cough
- sore muscles
- vomiting
- diarrhea
It's NOT OK to work out, not even moderately. Allow your body's immune system to do its job before stressing your body with any exercise.
[edit] Strenuous Exercise
It's NOT OK to do heavy weight lifting or intense aerobic exercise if you only have just a mild cold.
[edit] Other Considerations
If you work out in a public area, such as a gym, be considerate. Don't spread your germs, wipe down your equipment, wash your hands, and try to prevent sickness in the first place!
If you've been more severely sick but are now fully recovered, ease back into your workout routine. Work back up to your previous level of intensity so you don't shock your body.
