Here’s why you get cramps at night and how to avoid them

They appear without warning, often in the middle of the night: those famous cramps that make you jump out of bed. A pain that can disrupt sleep… But why do they appear, and above all, how can you avoid them? If these muscle contractions concern you, stay with us: solutions exist for more peaceful nights.
Why do we get leg cramps at night?

Nighttime cramps are sudden, involuntary contractions of certain muscles, most often in the  calves, feet, or thighs . They can last from a few seconds to several minutes, sometimes leaving persistent discomfort. Here are the most common causes:

  1. Insufficient hydration

You may not be drinking enough water throughout the day. When dehydrated, the body struggles to maintain a proper balance of  electrolytes  (potassium, magnesium, calcium), which are essential for proper muscle function. As a result, muscles become more susceptible to spasms.

  1. A mineral deficiency

A lack of  magnesium ,  calcium  , or  potassium  is a well-known factor in muscle cramps. These nutrients allow muscles to contract and then relax properly.

  1. Poor blood circulation

Sitting or lying down for long periods without moving can slow down circulation, especially in the legs. Less oxygenated, the muscles become more prone to involuntary contractions during rest.
