SARASOTA - It can improve everything from your fitness level to symptoms of Alzheimer's. There are only 55 CVAC Pods in the world, and one of them is in Sarasota.

Dr. John Lieurance, DC, ND, RMA calls it 'the pod.'

“We’re using it on patients with everything from Lyme disease to chronic viral infections, Alzheimer's, Parkinson's,” he said.

He says the CVAC Pod is one of the best ways to stimulate the body’s ability to keep things moving, helping the two main fluid compartments in our body: the lymphatic system, and the glymphatic system. That’s the system he says is tied to neurologic diseases like Parkinson's and Alzheimer's. Lieurance says pressure from CVAC (Cyclic Variations in Adaptive Conditioning) can help.

“When you’re in the pod, you’re gonna experience a change of pressure as if you were 22,000 feet up, to all the way down to sea level, and these changes in pressure actually move the lymphatic and the glymphatic," Lieurance said.

He says a lot of pro athletes use the pod as a form of exercise, too.

“ prime their muscles and to improve their conditioning,” Lieurance said.

He’s been using it himself, and he says his brain function is sharper than ever.

"I feel better than I did in my 20s," Lieurance said. “You’re gonna have less infections in the body, you’re gonna have more metabolic waste products being carried away, and you’re gonna have more nutrients being delivered to those cells and tissues.”

Sessions last about 20 minutes and Dr. Lieurance says it mimics the effects of flying, so if you can tolerate a plane ride, the pod is for you.
