What causes excessive sweating and leg cramps?

I work outside in the heat and sweat a lot, I get leg cramps at night. I try to stay hydrated, but it seems that no matter how much I drink, they still happen. They re mostly in my calves and sometimes in my thighs. Is there a supplement I should take, or something else I can do to prevent these cramps?

Thanks for posting in HCM.
I understand your concern.
Since you work in heat environment and sweat a lot, you are experiencing cramps as a result of electrolyte imbalance and calcium deficiency.
You need to do the following to overcome the same.
1. Drink good quantities of water to replace fluid loss.
2. Take Oral Rehydration Solution (ORS) and Citrus fruit juices regularly.
3. Improve your intake of calcium by consuming milk regularly and calcium supplementation in the form of tablets or syrup.
Gradually, you should be able to achieve homeostasis of electrolytes and calcium, which should prevent such symptoms from happening.
Hope the information provided would be helpful.
All the best.
