Why do cramps happen in the first place?

Cramps can happen anytime. Some people even experience them while they’re sleeping. However, usually you will suffer from them when you use a set of muscles to the point that their oxygen and nutrition supply is not sufficient to keep up with the energy use of the muscle.

But this is not only due to working the muscles too hard. There are a number of other possible reasons for a cramp ranging from overuse to deficiencies in potassium or magnesium to dehydration, fatigued muscles and poor blood circulation.

What can you do to prevent muscle cramps?


The probably biggest reason for muscle cramps is the overuse of a set of muscles. If you are usually not exercising at all and then end up with cramps in your legs while scuba diving then the simple remedy is to perform regular exercises specifically for diving during the year. This will strengthen your muscles and stamina and reduce the chances of suffering from cramps.


Many cramps are a result of having a cold muscle that suddenly is having to perform its duties. You can help your muscle easily by stretching before you hit the water. It’ll warm the muscle up and instantly help to prevent muscle spasms.

Stretching your calf and leg muscles even on the onset of a cramp can help prevent it. If you feel it starting to build up while you are under water then simply grab the tip of your fin, hold your leg straight and pull the tip towards you. This will stretch your calf and leg muscles and can often help to prevent the cramp!

How can you make sure that you don't get leg cramps? Showing a pair of fins on the beach to represent the issue.

You might still have to take it slow afterward with regards to your kicks. While you might be able to ease the cramp, you usually cannot avoid it completely.


No, not beer or other alcoholics. Drink lots of water or energy drinks. And at that moment avoid drinking alcohol the evening before you go diving as it will dehydrate you.

Dehydration is one of the most common reasons for a cramp yet it also is one of the easiest to avoid circumstances. Simply drink as much water as you can before you dive and you’ll stay hydrated for the dive.


What can you do to avoid leg cramps while scuba diving
