If you’ve ever experienced leg cramps at night, you know they’re no joke. They can rudely interrupt your sleep and startle you awake with a jolt of pain. Although they’re quite common, getting rid of leg cramps can be tricky, but there are a number of things you can try to prevent and treat them. Keep reading to learn all about what leg cramps are, what causes them, and how to stop leg cramps at night.
What Are Leg Cramps?
Leg cramps are episodes of sudden tightening and pain in the muscles of the leg, typically in the calf, foot, or thigh. They’re involuntary muscle contractions that can last seconds or minutes, and can affect your sleep, exercise, and general quality of life. Although painful to live with, leg cramps are generally harmless.
Leg cramps at night, also called nocturnal leg cramps, happen when you’re not very active or when you’re asleep. They may wake you up, make it harder for you to fall back to sleep, and leave you feeling sore all night. About three out of four cases of leg cramps reported happen at night.
If you’re experiencing frequent or severe leg cramps, it’s essential to consult with a healthcare professional to identify the underlying cause.
What Causes Leg Cramps at Night?
The exact cause of leg cramps is not clear. However, some common factors and potential causes of leg cramps at night include:
- Dehydration– Inadequate fluid intake can lead to dehydration, as can the consumption of alcohol.
- Electrolyte Imbalance– An imbalance in electrolytes such as potassium, magnesium, calcium, and sodium can affect muscle function and lead to cramps.
- Overuse or Strain– Overexertion of muscles, especially during physical activity or exercise.
- Muscle Fatigue– Muscles that are tired or overworked are more prone to cramping.
- Medications– Some medications, such as diuretics, statins, and certain asthma medications. These medications can result in an electrolyte imbalance.
- Pregnancy– Pregnant women often experience leg cramps, especially during the second and third trimester.
- Medical Conditions– Underlying medical conditions such as diabetes, kidney disease, thyroid disorders, and neurological disorders.
- Age– Older adults may be more prone to muscle cramps.
How to Stop Leg Cramps at Night
1. Stay Hydrated
Dehydration can contribute to muscle cramps, so make sure you’re drinking enough water throughout the day. Also, consider not consuming alcohol, especially close to bedtime. Alcohol consumption has been found to be strongly associated with having leg cramps at night. Not only does it dehydrate you, it can lead to muscle tissue damage and deficiencies of vitamin B and D, iron, zinc, and potassium. Alcohol also contributes to the accumulation of lactic acid inside leg muscle tissues.
2. Stretch Before Bed
Gentle stretching of your calf muscles before bedtime may help prevent leg cramps. Stand facing a wall with your hands up against it. Step back with one foot, keeping the knee straight. Bend the front knee while keeping the back heel on the floor, and hold for 30 seconds. Repeat with the other leg.
3. Stretch to Get Rid of an Active Leg Cramp
If you’re actively having a leg cramp during the night, you can also stretch for relief. If your calf muscle is cramping, reach down and pull your toes toward your head until the cramp eases. You can also try lunging forward with the leg that isn’t cramped, stretching out the cramped leg behind you. Also try standing on your toes for a few seconds, and see which stretch works best.
4. Apply Heat
Heat can soothe tight muscles and give you relief from leg cramps. Apply a hot towel, heating pad, or hot water bottle to the affected area. If you deal with severe or prolonged leg cramps, you may want to run a warm bath or hop in a hot shower. Taking a warm bath before bedtime can also help relax your muscles and make it less likely to experience leg cramps.
5. Massage Your Muscle
If you get a night leg cramp, try massaging the affected area with both hands. This can help loosen up the tight muscle relatively quickly and give you relief.
6. Magnesium Supplements
Some studies have found that magnesium deficiency may contribute to muscle cramps. Consult with your healthcare provider before taking supplements, but if you get the go ahead, it’s worth a try. Magnesium is essential in regulating your body’s functioning. It’s involved in more than 300 of your body’s biochemical processes, including muscle contraction and nerve transmission.
7. Eat More Potassium-Rich Foods
Ensure that your diet includes sufficient potassium, as low levels of potassium can lead to an electrolyte imbalance and may contribute to muscle cramps. Bananas, oranges, and potatoes are good sources.
8. Use Proper Bedding
Make sure to sleep under loose sheets and blankets, especially if you sleep on your back. Sheets that are too fitted and tight can compress the nerves and lead to cramps.
9. Walk or Shake the Leg
Sometimes the best remedy for leg cramps is to walk it off. Walking encourages small arteries in your leg to enlarge, which increases blood flow. Since sometimes leg cramping is due to inadequate blood flow to the muscles, walking can be helpful.
10. Avoid Prolonged Sitting or Standing
If possible, avoid sitting or standing in the same position for long periods during the day. Research has shown that people who spend a lot of time standing each day are at a higher risk of leg cramps. When you’re on your feet, but not in motion, blood and water tend to pool in your lower body. This can lead to fluid imbalances, as well as muscle and tendon shortening, all of which can lead to cramping.
