Muscle Cramps: What are They and How to Relieve Them

Muscle cramps can affect different people differently. They can cause discomfort, making it hard to walk or move around, and can make it difficult to sleep if experienced at night. Certain muscles, including the hamstrings and quadriceps in the thighs and calf muscles in the lower legs, tend to be most prone to cramping. Cramps also commonly affect muscles in the hands, feet and arms, but can also affect many other muscles in the body.

The most common symptom of a muscle cramp is a sudden muscular pain, soreness or spasm that can last anywhere from a few seconds up to ten or more minutes and can recur multiple times.

So, what causes muscles to cramp?

The primary causes of muscle cramps include:

Overuse: Cramps can occur as a result of muscle fatigue from overuse. This typically occurs during exercise or in the hours immediately following a heavy exercise session.

Dehydration: Exercise can contribute to dehydration, which is a common cause of muscle cramps. Without adequate fluid, muscles can become sensitive and contract involuntarily.

Electrolyte imbalance: Calcium, magnesium, sodium and potassium all contribute to healthy muscle function. Low levels of any of these minerals can cause muscles to cramp.

Blood flow: Poor blood flow to the legs can contribute to muscle cramps in the hamstrings, quadriceps and calf muscles.

Luckily, there are a number of approaches that can help relieve muscle cramps and reduce the likelihood of them recurring:

Hydration: Drinking water or a sports drink with electrolytes can help address dehydration and electrolyte imbalances, which may help reduce the risk of muscle cramps.

Stretching: Lightly stretching the affected muscle may help relieve cramps. The muscle can also be massaged gently while holding the stretch.

Movement: Getting up and walking may help relieve leg cramps by encouraging the muscle to extend and relax after contracting.

Heat: Soaking in a hot bath or applying a hot water bottle or heating pad to the affected muscle may help provide temporary relief from cramping.

Magnesium is essential for healthy muscle function, and an inadequate intake of the mineral can contribute to the occurrence of muscle cramps.

Supplementing with magnesium in the form of gummies, capsules or tablets can help support healthy muscle contraction function and may help reduce mild muscle spasms and twitches when dietary intake is inadequate.

The best way to help prevent muscle cramps is to avoid the primary risk factors of overuse, dehydration and electrolyte imbalance.

Avoid overexertion or increasing your level of exercise too quickly. Building up activity levels over time can reduce the risk of muscle soreness and cramping. Stretching before and after exercise can also help prevent cramps from occurring. It's a good idea to focus on the muscles most prone to cramping, such as the quadriceps, hamstrings and calves.

Be sure to drink enough fluids throughout the day, particularly during and after exercise, to avoid dehydration. Drinking water and sports drinks containing electrolytes during exercise can help maintain adequate levels of sodium, potassium and magnesium. Where dietary intake is inadequate, supplementation may also help support adequate levels of these essential minerals.

If you regularly experience muscle cramps or soreness in your feet or lower legs, remember to wear appropriate shoes that fit well and provide good support.

If you experience frequent or severe muscle cramps, it is important to speak to your doctor to help identify and manage any underlying medical conditions that could be contributing to your symptoms.

Magnesium: Supplementing with magnesium may help reduce muscle cramps, mild muscle spasms and twitches when dietary intake is inadequate and supports healthy muscle function.

Potassium and sodium: Maintaining adequate intake of potassium and sodium helps support electrolyte balance.

Protein powder: Taking an easily absorbed form of protein powder provides amino acids important for muscle health, repair and recovery.

Branched chain amino acids (BCAAs): BCAAs are essential amino acids that may help reduce exercise-related muscle soreness and support muscle recovery.

Always read the label and follow the directions for use.
