At the same time, avoid suddenly increasing your exercise intensity. Gradually build up activity so your muscles have time to adapt.
### Pay attention to footwear and sleeping position
Supportive footwear may be helpful for some people. Mayo Clinic also suggests loosening or untucking bedding around the feet, since keeping the foot pointed downward for extended periods may contribute to a cramped position. Mayo Clinic News Network
## What About Magnesium and Other Supplements?
You may have heard that nighttime leg cramps are always caused by a magnesium deficiency. The reality is more complicated.
Mineral imbalances can contribute to muscle cramps, but not every person with nighttime cramps is deficient in magnesium, potassium, or calcium. Mayo Clinic
Taking supplements without knowing whether you need them isn't necessarily the answer. Some supplements can interact with medications or be inappropriate for people with certain medical conditions.
If you experience frequent cramps, talk with a healthcare professional about whether your diet, medications, medical history, or symptoms suggest that testing or supplementation could be appropriate.
