Leg cramping is extremely painful and can be a real nightmare, especially when it wakes you at night.
Nocturnal leg cramps are sudden, involuntary contractions of the calf muscles during the night or periods of rest.
Apart from the calves, contractions can also occur in the soles of the feet or other muscles in the body. At the location of the cramp, you may feel a hard lump of muscle tissue.
The duration of these cramps can be anywhere from a few seconds to several minutes. Although the intense pain may go away, muscle soreness may remain for some time.
Anyone can get these types of cramps, but they are more common in people who are middle-aged or older. They may also occur quite frequently in teenagers and in people who exercise at night.
The precise cause of leg cramps at night is unclear. However, there are many contributing factors that can cause this painful problem.
Here are some of the reasons why you have leg cramping at night.
Contents
1. Dehydration
Proper hydration contributes to a healthier body and mind. It also impacts the performance of your muscles.
Water comprises 75 percent of muscle tissue and helps them contract and relax easily. So, not maintaining proper levels of hydration during the day may be one of the big causes of leg cramps at night.
Water is also important for proper circulation of nutrients in the body. Without water, muscles will be deprived of important nutrients, which can lead to imbalances of electrolytes (mainly sodium, potassium, calcium and magnesium).
In fact, even small amounts of dehydration may hinder athletic performance and increase the chance of cramps at night.
2. Nutritional Deficiency
Any kind of imbalance of mineral electrolytes—sodium, potassium, calcium and magnesium—in the body can contribute to nocturnal and exercise-associated cramps.
These minerals are responsible for both nerve impulses and muscle contractions, and keep your muscles working smoothly.
Sodium, one of the main positively charged mineral ions or electrolytes in body fluid, helps maintain a normal body-fluid balance and is critical for nerve impulse generation and muscle contraction.
Potassium is an important electrolyte found in all body cells, including muscle and nerve cells. It works along with sodium and chloride to generate electrical impulses in the nerves and the muscles.
Calcium is involved in muscle contractions as well as the generation of nerve impulses.
Magnesium aids in stabilizing adenosine triphosphate (ATP), the energy source for muscle contractions, and also serves as an electrolyte in body fluids.
Deficiency of any of these minerals can lead to cramps and other muscle-related problems.
Additionally, certain B vitamins impact muscle function, particularly vitamin B12.
3. Overexertion or Prolonged Standing
Standing on a hard surface for a long time as well as standing while wearing high heels or poorly fitting shoes can contribute to muscle fatigue or overexertion. This in turn can cause leg cramps at night.
A 2012 study published in Ergonomics showed that prolonged standing at work may be an important risk factor for varicose veins and nocturnal leg cramps among both men and women.
The study even suggests that interventions to interrupt or reduce prolonged standing at work should be implemented to prevent these problems.
Also, sitting improperly or putting your legs in awkward and uncomfortable positions when sleeping can contribute to nocturnal leg cramps.
4. Pregnancy
Pregnant women often experience leg cramps at night, usually starting in the second trimester and lasting through the third trimester. These cramps may vary in intensity, from mild to extremely painful.
Leg cramps during pregnancy may be due to the increasing pressure of the uterus on certain nerves, fatigue, or reduced circulation in the legs from the pressure of the baby on blood vessels.
During pregnancy, if you frequently suffer from leg cramps either during the day or at night, it is important to discuss this problem with your doctor.
5. Hypothyroidism
A low level of thyroid hormones can indirectly contribute to muscle weakness as well as calf cramps at night.
The thyroid hormones can affect calcium absorption and utilization. Calcium deficiency is associated with muscle weakness, numbness, pain and cramps.
Also, low thyroid hormones lead to low metabolism. High metabolism is important for energy as well as how your muscles feel after doing your regular exercises.
A low level of thyroid hormones also often increases inflammation that may be contributing to your muscle cramping and pain.
6. Uncontrolled Diabetes
Diabetes can also contribute to leg muscle cramping. In fact, it is a symptom of a form of nerve damage called diabetic neuropathy, one of the complications of uncontrolled diabetes.
Besides the sharp pain in the leg muscle, diabetes patients may also experience tingling and numbness.
Elevated blood sugar also causes excessive urination and subsequent dehydration, which contributes to night leg cramps.
If you’re experiencing muscle cramps related to diabetes, consult your doctor immediately. Catching nerve damage early is important in preventing further complications.
Blood flow problems such as peripheral arterial disease may also contribute to nocturnal leg cramps.
7. Alcohol Abuse
Excess alcohol intake is not good your health. Peripheral nerves can become damaged due to too much alcohol use, causing alcoholic neuropathy. Leg pain and muscle cramps are common symptoms of alcoholic neuropathy.
Excessive drinking causes dehydration due to the diuretic effect of alcohol. Plus, it can cause a magnesium deficiency.
Another important point to note is that excess alcohol intake increases the content of lactic acid in your body. Excessive lactic acid can lead to cramps or pain in your muscles.
8. Certain Medications
Another cause of nocturnal cramps is a side effect of medications.
Certain medicines, especially cholesterol-lowering agents (statins) and diuretics, contribute to the loss of water and electrolytes from the body. This in turn makes you more prone to having cramps.
Other medicines, such as antipsychotics, birth control pills and steroids, can also cause cramps.
If cramps start suddenly after you begin taking a new medication, consult your doctor.
Tips to fix and prevent leg cramping at night:
- Drink plenty of water and other healthy fluids to prevent dehydration.
- Drinking sports drinks with electrolytes can be useful in preventing the problem.
- Steer clear of alcohol, coffee and soda beverages that rob the body of water, increasing the risk for cramping.
- Stretch your leg muscles before going to bed. Stretching your calves can help ease muscle tension and reduce the chance of having a cramp at night. A 2012 study published in the Journal of Physiotherapy reports that stretching before sleep reduces the frequency and severity of nocturnal leg cramps in older adults.
- Riding a stationary bicycle for 10 minutes before you go to bed is another good option.
- Keep blankets and bed sheets loose around your feet so that your toes are not distorted.
- If you have a cramp, massage the cramped muscle with your hands for 10 to 15 minutes.
- Walking or jiggling the leg after a cramp will send a signal to your brain that your muscle needs to contract and then relax. This can promote faster recovery.
- Applying a hot compress to the cramped muscle can relax and loosen it up, thus easing the cramp.
- Make sure to get enough potassium in your diet. Good sources of potassium include bananas, dates, apricots, grapes, cabbage, broccoli, oranges, grapefruit, fish, pork and lamb.
- Also, try adding more magnesium to your diet. Nuts and seeds are excellent sources of magnesium.
- Pregnant women should consult a doctor about taking magnesium supplements.

I have personally overcome the excruciating pain and given out this information to my
friends. As soon as you feel the first signs of the cramp setting in, press your thumb of
the foot/leg involved on a hard surface (floor or bed post) for a few seconds and you will be surprised of the relief in a jiffy! Try it and share it.
I would just like to thank you for the piece on leg cramps it was very helpful to me as I suffer with it all the time.
I enjoy reading the different remedies you write about.
Thank you,
Sincerely
Patricia Martin
Dear Patricia
I suggest a homoeopathic medicine Ferrom Phos 200 liquid 5 drops in two tablespoon water 3 times for one week. I am sure this problem will not repeat again.

When you feel that your leg will get cramped, immediately stand up on the bed or get down the bed and stand straight. It is a proven idea & I apply this whenever I feel that my leg is being cramped.
Immediately stand up straight before your leg cramp
Pickle juice works for me but sometimes not as fast as I would like. . . . .will try the soap to prevent it BEFORE IT HAPPENS!

Hello to all that get a cramp u can get instant relief by being barefoot and putting the effected leg ,foot on a cold floor. A tile floor is the best and it will be gone in seconds.
Salt under the tounge , been suffering for over 20 years. Recently bought Himalayian sea salt, brilliant. But try just table salt at first.
