The derivative bath, who is it for and why should I do it?

Who is the derivative bath designed for?

Up to 150 years old, for both men and women!

Our living conditions have changed over the past seventy years and our core temperature has increased on average by 6 tenths of a degree and our bodies are being subject to a permanent state of inflammation. This has led to many problems: obesity, diabetes, inflammatory pain, depression, etc.

You get the best with YOKOOL, the original and authentic cooling pocket designed specifically for use in the Derivative Bath!

The unique YOKOOL® cooling pocket has been ergonomically designed and complies with the strictest health regulations. It has revolutionised this technique and made it accessible to everyone.

What are the benefits of the derivative bath?

  • Reduce inflammation and relieve pain
  • Improve sleep and restore skin tone
  • Cool down in warm temperatures (heatwave, blushing...)

  • Protect yourself from obesity and type 2 diabetes
Who is Yokool

Yokool’s story

We are the first and only manufacturers of cooling pockets that are designed specifically for Derivative Baths. We have been developing our YOKOOL range for 12 years to satisfy the needs of our customers.

In the past, Derivative Baths had to be practised in a bidet or over a bucket. It was a long process and you could not do anything at the same time... 

We tried different gel pockets, there are lots of variations, sizes, colours, made of plastic, more or less resistance, and occasionally they break, which releases the gel that then sticks and stains. Having all of this in our underwear made us walk like ducks. Not discrete at all!

Finally, it occurred to us that we should create a fabric pad that is washable, ergonomic, comfortable, long-lasting, and discrete, and can be worn by men as well as women.

Our objective is to produce a product that complies with the strictest health regulations to make it portable and accessible to everyone.

Is the Derivative Bath medicinal?

The Yokool Derivative Bath is not a medicine, neither traditional nor modern, neither alternative nor exotic, nor ying nor yang medicine. It does not cure or heal.

It is a form of natural, universal life. The Derivative Bath is no more dangerous than walking around for a few hours a day with nothing under your kilt, a djellaba, sarong, skirt, or ventilated trousers.

Who is the YOKOOL Gel Pocket designed for?

It is unisex and ergonomic; therefore, it is suited to this part of the body
