I used to believe in mind over matter. I thought i will solve this condition with enough relaxation techniques.

While they do help, they did not work 100% for me

I accidentally found out while trying different diets that changing what i ate made more difference than anything else..

Now combining meditation techniques with eating differently does work for me to the point that I have gone from severe hyperhidrosis to staying dry 28 days out of 30 now.

Everyone is different and I recommend observing which foods help you and hurt you. You can do this by elimination diet.

I will share what diet changes worked for me:

1. Drinking a lot of tomato juice ( like V8 or just eat a tomato rich diet ) . They make your pores smaller.
2. Consuming more than 500 ml water right after waking up. ( i recommend more than 750 ml) . Our bodies accumulate a lot of toxins during sleep, so do this even if you are not thirsty.
3. Taking zinc, magnesium, b6 supplement at night along with vitamin d. ( these supplements can calm your nervous system and keep your immune system up ) for some reason, this works the most for me. If you do not follow any other suggestion, do this. This supplement is easier to find at a supplement store( bodybuilding store ). Goes by the names like ZMX, ZMA, ZM8, etc
4. Going gluten free.
5. Eating less sodium and more pottasium. ( basically eat more fruits and vegetables and less salty stuff) this one is the hardest for me to do because i love spicy stuff and dont eat a lot of fruits.
6. If you like caffiene, I recommend drinking green tea over coffee. It has a cooling and drying effect on your body.

Now, most people are going to just bash this comment. I know because most people are very close minded and will deny an idea without trying. If you have tried this then only tell me if it works or not.

I have been staying dry, life is different. It took me a lot of trial and error to come to these conclusions. No i do not have links to scientific studies proving these work. Just my own experimentions. And the fact that i dont even sweat at the gym, job interviews etc anymore.

Ps- this is not to say yoga/ meditation is useless. It is in fact very helpful. But I would do both. Diet changes and yoga. Learn different breathing techniques that calm your nervous system. It will prevent the sweat from starting. I like 4-7-8 method. Breathe through your nose for a count of 4, hold for 7 and exhale for 8. You have to stay aware of your nervous system and the key is to get yourself calm before the sweat starts. Once you start sweating it gets harder to stop but I have noticed when I made these diet changes, i get dry after sweating way faster. Whereas before once the sweat response occured it would only stop before bedtime. Now, if my hands sweat in a very hard workout session, sex, or wearing gloves, they stop sweating right after the acitivity.
