Muscle Cramps: Causes and Prevention
Muscle cramps are part of being human. Chances are you have experienced them at some point. Whether you got a “charlie horse” in the middle of the night or felt the onset of a cramp while working out in the heat, they aren’t fun and definitely remind you you’re not invincible. The key to preventing muscle cramps is understanding how they happen.
Not all cramps are the same. They can occur throughout the body from your fingers to your toes and even your internal organs. Of course the muscle cramps we talk about here are those that occur in your muscles. They are most common in your arms and legs, as well as your back. Muscle cramps like these are characterized by a tightening or over excitement of the muscle which leads to pain and even temporary immobility.
Muscle cramps are commonly caused by dehydration. Fluid loss through perspiration when working out or working outside can lead to this dehydration. This is one of several reasons it is important to drink plenty of water throughout the day. They can be a precursor to heat stroke and serve as a warning sign to you that you need to hydrate and cool off.
Muscle cramps can also come from muscle fatigue or injury. Sometimes if you work your muscles too hard, they will cramp up. Similarly, occasionally cramps will occur as your muscles try to compensate or protect an injury, like a broken bone. This is commonly seen when muscles in the back spasm due to inflammation around a ruptured or bulging disc.
Vitamin deficiencies and some prescription medications can also lead to muscle cramps. Taking a good multivitamin and being aware of the side effects of your prescriptions can ward off these types of cramps.

Muscle spasms are involuntary contractions of a muscle. These can happen anywhere in the body although spasms in the back are more common. They can be uncomfortable or accompanied by debilitating pain. The reasons for the spasms differ as much as the symptoms do. When looking at what causes muscles spasms, many possibilities exist.
Overtraining, mostly found in weight trainers, runners, and serious athletes can lead to injury and physical exhaustion. When training, whether for an athletic event or for weight loss, people sometimes get over anxious and quit listening to their body. Being aware of what causes overtraining can help you avoid it and minimize time spent on the sidelines. Listening to your body and being aware of its limits will reduce the chance of overtraining.
