Before you get started, please familiarize yourself on how the CoreControl works. You can check the published study that goes in depth with the CoreControl. I was able to replicate the functions for my DIY CoreControl using the design specs from this study.

When our body overheats, it goes through a thermoregulation process to expel excess core body heat. The palm of our hands is one of the body's "radiators" to expel heat. Why the palm of the hands? The palms have numerous capillaries which cover a large surface area, allowing the removal of excess heat from the body. The vacuum is supposed to draw the blood to your hands to increase the heat transfer rate. The faster you remove the excess body heat, the faster you will recover from exercise.
You may have heard about rubbing ice cubes on your wrist to reduce recovery time. However, this method is inefficient because low temperatures cause the blood vessels to constrict, thereby reducing the blood flow. The CoreControl applies a similar concept, however, is more effective because it uses a vacuum to draw the blood quickly to the palms, and the controlled temperature prevents constriction of blood vessels.
I built my first homemade CoreControl a year ago. Due to numerous requests, I decided to build a second one in order to write a detailed step-by-step guide. Let's have some fun!
