Have you ever experience foot cramps before? The one that suddenly restrains your movement and makes you struggle in vain? Cramps most likely to occur in athletes, elderly people and pregnant women. But we are no exception either.

It is not a serious condition but they may have a great impact and become a threat to our physical and mental health if occurs frequently. The general impression when it comes to cramps is calcium deficiency. So a lot of people desperately add calcium tablets in their diet, but the condition did not improve.

The American Family Physician studied the causes of mid-night cramps in 60% of adults in 2012 and found eight reasons for cramps as follows:

1. Cold feet – Having the fan or air conditioner directly blows your feet or not using quilts during the winter night will make your feet suffer from cold, thus increase your chance of getting cramps.

2. Excessive exercise – Glycogen stored in the body is used as a source of energy during exercise. If it has been used too much and the calories are not replenished in time, foot cramps or muscle fatigue may occur.

3. Dehydration, electrolyte imbalance – Long exposure in the hot sun without sunscreen and timely replenishment of water, or sweating during exercise will make the body loses water and electrolyte. Drinking tea and coffee can also cause the body to be dehydrated and electrolyte imbalance.

6. Pregnant women – Total fluids and electrolytes are not balanced during pregnancy. The fetal load in the uterus also causes poor blood circulation in the lower limbs.

7. Kidney disease or other diseases – Patients with kidney disease using dialysis can’t metabolize body waste normally, hence drastic changes in the body’s electrolytes that can cause cramps. Cardiovascular diseases, high blood pressure, hyperlipidemia, and diabetes are other diseases that prone to cramps due to changes in ambient temperature that affect blood circulation. Sciatica, spinal neuropathy, and neuropathy may also cause cramps.

8. Emotional tension – Muscles suddenly and involuntarily contracted, hence causing muscle stiffness and pain during tension. Muscle cramps usually occur in the legs and feet, most commonly calf gastrocnemius, soles, and toes. Cramps occur in the biceps femoris (back of the thigh) and quadriceps (front of the thigh) are called thigh cramps—more serious and the pain lasts longer.
