POTENTIAL REASONS FOR SPASMS
There are several reasons muscles spasm. Here are a few of the major concerns:
1) Dehydration – If the body doesn’t get enough water, the skeletal muscles react with painful, short-lived spasms
2) Electrolyte abnormalities – Usually related to dehydration, the lack of electrolytes means it’s time for some Gatorade or other sports drink that will help restore the balance
3) Brain chemicals – A certain muscle spasm called dystonias is an abnormality in the brain chemicals that helps transmit signals.
4) Strain – When muscles are overtaxed from work or athletic activity, particularly if they have been held in the same position for long periods, the cells can be depleted of energy, causing a spasm. This is true of athletes who are performing on a hot day, or with construction workers who are laboring on projects out in the heat. It can also result from such activities as snow shoveling or other chores.
5) Narrowing of the arteries – People with atherosclerosis or peripheral artery disease may experience muscle spasms because of inadequate blood flow and nutrient depletion.
TYPES OF SPASMS
Leg spasms are often related to strain during exercise, but nocturnal leg cramps and restless leg syndrome are two types that can affect the calf and toe during or just after sleep. For unknown reasons, these sleep cramps increase as we age, and research has yet to undercover a cause.
