DOCTORS REVEAL WHY SUMMER HEAT TRIGGERS AGONIZING MUSCLE CRAMPS—EVEN AT REST

Why Do Muscle Cramps Happen—Even When You’re Not Moving?

A cramp is an involuntary and very painful muscle contraction. It can be limited to a single muscle or affect a group of muscles. Muscle cramps most often occur during physical activity, but they can also hit when you’re completely still, especially at night. Dehydration is the most common culprit behind cramps.

You’ve almost certainly felt that sudden, sharp pain that appears out of nowhere. It surges quickly through your calf or foot, usually bringing stiffness and a hardening of the area. Those are the classic signs of a muscle cramp. Basically: it’s your muscle throwing a surprise party, but it’s not the fun kind.

Heat Cramps: When High Temperatures Make Trouble

When it’s hot outside—and you’re pushing yourself with intense physical effort—you can end up with what doctors call “heat cramps.” What are they exactly? In what situations do they strike? How can you prevent and manage them?

The real troublemaker is the imbalance of water and mineral salts inside your muscle cells. Excessive sweating, which is worse in hot conditions and with exercise, triggers this imbalance. When you sweat a lot, you naturally lose significant amounts of water and electrolytes (think magnesium, calcium, potassium and friends), which evaporate through your skin. If you try to fight this by drinking lots of plain water, you might replace the lost fluids, but you don’t restore those lost electrolytes. The ones still in your system then become very diluted. And that lack of electrolytes is what jumps out and triggers the cramp.

How to Prevent and Soothe Summer Muscle Cramps

• The best way to avoid cramps during hot weather is to drink water regularly—don’t wait until you’re thirsty.
• To keep a healthy balance of mineral salts in your muscle cells, make sure to eat foods rich in magnesium. So maybe give spinach or almonds a chance at your next snack.

Cramps are very common. While they are completely harmless, they can certainly pack quite a punch in terms of pain. Wondering where they come from and how to soothe them quickly and effectively? You’re in good company!

Night Cramps: Don’t Let Your Calves Ruin Your Dreams

If you’d rather not be jolted awake by a cramp in the middle of the night, stretch the muscles usually affected before heading to bed: your calf muscles, the ones at the back of your thigh, and the muscles in your feet. It’s also recommended to avoid sleeping with your foot stuck in a fully pointed position—so maybe give your feet a break from that dramatic ballet pose.
