Sometimes it can be from low potassium. I would recommend that you take a potassium pill each day if you get muscle cramps in your legs a lot. But just take 1 a day. Or you can just eat more banana's to make it easier. :)
Having had "charley horse" cramps since I was quite young I have looked for answers to this question for years. I found out that there are two things that are believed to cause muscle cramps. Low potassium is one and dehydration is the other. I read this in several web sites and/or medical "lifestyle-type" books. I've been told it is necessary to eat a banana(a good source of potassium) every day. As for water( I read this on line)- I found that if I drink about 12- 20 ounces of water several times a day-I don't have cramps AND generally feel better anyway! Although I have never read about this, I personally came upon this solution myself:For several years now, I have found that drinking a cup of warm milk relieved the cramps- I don't think there is any reason for this-maybe it haelped me to relax? Hope this proves to be helpful-jbc41076@Yahoo.com
There are several causes of muscle cramps. One of the most common is dehydration or low electrolytes. This can be taken care of by simply drinking something like Gatorade or Powerade.
Magnesium deficiency can cause muscle cramping. Potassium deficiency can, as well. These are minerals, not vitamins.
Your muscles cramp up after exercise if you do not stretch
The process that causes muscle tiredness can be reversed because once the muscle starts getting the right products it needs it can start its normal process. This is why when the muscle gets more oxygen it stops cramping.
Potassium
Arthritis is one of the causes. I'm not sure of any others. * Other causes can be lack of fluids (water). Muscle needs H2O to function properly. * Can also be pregnancy, nerve irritation or fatigue.
exercise
There are a couple of great aids that can prevent cramping of the muscles. Always warm up before exercise to loosen the muscles. After a workout where you may have over-worked a muscle, be sure to add a warm compress to the muscle to keep it from cramping.
causes cramping
Sometimes you get foot cramps simple because your body is dehydrated.If your feet are cramping because of excersing , you many want to focus more on getting your leg and calf muscle stronger.This may help eliminate the foot cramping.
maybe a tense jaw
Muscle contraction and relaxation require salts which are lost through sweat during vigorous exercise. This causes some muscles particularly low in these materials to contract uncontrollably, creating a cramp.
