What is Vibracool?

VibraCool is a wearable, drug-free pain relief device that combines high-frequency vibration with hot or cold therapy to block pain and promote recovery. It features a small vibrating unit paired with a gel pack that can be used cold for inflammation or warm for stiffness and chronic pain. The vibration not only disrupts pain signals through mechanical stimulation (M-Stim) but also increases blood flow to the affected area, helping the body heal faster. Developed by MMJ Labs, the same company behind Buzzy, VibraCool is ideal for those seeking pain relief without medication and works especially well for muscle soreness, joint pain, plantar fasciitis, and post-injury discomfort.

How does VibraCool works?

VibraCool combines focused vibration with cold or heat therapy to block pain signals, reduce inflammation, and improve blood flow—helping your body heal faster. Its effectiveness is based on two key scientific principles:Gate Control TheoryandDiffuse Noxious Inhibitory Control (DNIC).

1. Gate Control Theory of Pain

The gate control theory is the basis for the design of VibraCool®. The premise is that when nerves receive non-painful signals such as vibration or cold, the brain closes the gate on pain signals. For example, if you hit your finger with a hammer, you might instinctively begin to rub it, shake it, or run it under cold water. You are sending non-pain signals through your nerves to close the gate on the pain signals. 

2. Descending Noxious Inhibitory Controls

VibraCool doesn’t just stop pain at the surface—it also triggers your body’s internal pain-control system.
When the cooling pad delivers strong cold, it activates a process called Descending Noxious Inhibitory Control, or DNIC.
This causes the brain to release inhibitory signals that raise your overall pain threshold—like turning down the volume on pain across your body.

In simple terms: the intense cooling sensation makes your brain less sensitive to pain anywhere else.
