Leg cramps (painful muscle spasms) causes, prevention, and countermeasures

This time, I would like to talk about "What causes leg cramps? I will teach you how to prevent leg cramps at night."
I'm sure there are more than a few people who have experienced pain from cramping in their legs in the early morning while sleeping at night.
You can also get cramps when walking during the day, or cramps when you do something. If you are a terrible person, your hands may get cramped.
In fact, these "fishing" are considered to be caused by lack of water, lack of minerals, coldness, and various diseases.
Thank you for your high evaluation and channel registration!
