This Is Why Your Legs Cramp at Night (And How to Stop it From Happening Ever Again)

Nocturnal leg cramps (the leg cramps at night) are not only painful, but they also prevent you from having a good night’s sleep, which is important to your health. So, now you probably ask yourself this question – why is it always at night? Well, it’s because of lack of physical activity during the day. Lack of fluids and blood flow to the legs are some of the most common reasons for nocturnal leg cramps. The cramps and pain generally last for a few seconds. But the resulting muscle soreness can continue for up to a couple of days. Individuals who suffer from these cramps are usually above 50 years old, but that doesn’t mean that younger people are exempt. Leg cramps most commonly affect the calf muscle; however, some people have experienced them in their feet and thigh muscles as well.

Leg cramps at night and Restless leg syndrome

First, you should know that both nocturnal leg cramps and restless leg syndrome (RLS) occur during sleeping hours but that is the only similarity between the two conditions. You should also know that there are many differences between leg cramps at night and restless leg syndrome, such as:

  • restless leg syndrome does not cause pain or cramping, while nocturnal leg cramps do.
  • restless leg syndrome is more of a discomfort or crawling feeling in your legs.
  • restless leg syndrome causes the desire to move the legs, while nocturnal leg cramps often prevent movement.

Moving the leg in restless leg syndrome offers relief – moving the leg in nocturnal leg cramps does not, instead stretching is required. This means that the syndrome forces you to move the limbs, but when you have cramps – the last thing you want to do is move.
