What Vitamin Are you lacking when you are tired?
You may have heard this improbable advice
before: Getting more exercise can help you feel more energetic. "Many
people think, 'If I'm feeling so fatigued, how am I going to bring myself to
exercise?'" says Jessica Matthews, MS, an exercise scientist with the
American Council on Exercise. Yet the research (on real people, not mice) shows
this to be true. Part of the reason for this effect comes from what happens
when you exercise: your heart pumps more oxygen and nutrients into your
bloodstream, your lungs and cardiovascular system work better and you feel more
energetic. What's more, the type of physical
activity that works best for alleviating fatigue "is not that intense
exercise that people feel they have to do," Matthews says. The notion that
exercise has to be grueling in order to work keeps many exhausted women from
lacing up their sneaks.
