No one knows exactly
why muscle cramps occur. The
strongest current theory holds that they are caused by inadequate stretching
and muscle fatigue or are brought on by dehydration and depletion of salt,
potassium, magnesium and calcium.
Cramp Facts
|
- As we
get older, we’re more vulnerable to cramping because of muscle
atrophy and/or circulation problems.
- Nighttime leg cramps are especially common and may be caused by
inactivity, smoking, impaired circulation, or low levels of the
minerals sodium, potassium, magnesium or calcium.
- Other
causes of cramps:
pregnancy, hypothyroidism, kidney failure, Addison’s Disease and
peripheral neuropathy (usually a result of diabetes.)

To Prevent Cramps
|
- Stay
hydrated.
- Stretch regularly.
- Stay
active to maintain muscle and circulation.
- For
women, take a Calcium/Magnesium supplement a few times per day and
before bedtime. Aim to
get a total of 500-700mg Calcium and half that amount of Magnesium.
- Eat
plenty of potassium-rich foods such as bananas, tomatoes, broccoli,
grapefruit, cantaloupe, oranges and potatoes.
- Check
your iron levels, especially if you are getting leg cramps at night.

that is already in progress
