(HealthDay News) -- While exercise can help you feel better physically and emotionally, it may be wise to skip a day if you aren't feeling well.
The U.S. Centers for Disease Control and Prevention says it's a good idea to take the day off from exercising if:
- You feel very tired.
- You have pain or swelling in a joint or muscle.
- You feel any chest pain.
- You feel short of breath.
- You've been asked to refrain from exercise by your doctor because of illness, injury or surgery.
