What is cold therapy?

Cold therapy, also known as cryotherapy, is a treatment method that applies cold temperatures to the body to reduce inflammation, swelling, and pain. It works by constricting blood vessels and slowing nerve signals in the affected area. ZORVICK cold compression devices deliver targeted cooling to joints such as knees, necks, and shoulders for fast, drug-free relief.

How long should I use cold therapy?

We recommend 15–20 minutes per session, 3–4 times daily. Always allow at least 30 minutes between sessions to protect your skin and give the treated area time to return to normal temperature. Never apply cold therapy for more than 20 minutes at a time.

Is ZORVICK suitable for elderly users?

Yes. ZORVICK devices are specifically designed with elderly-friendly features: large buttons, clear displays, adjustable straps, and an ergonomic design that is easy to put on and take off. We also offer 24/7 customer support and a 365-day warranty for peace of mind.

Are ZORVICK devices FDA approved?

ZORVICK cold therapy devices are manufactured in FDA-registered facilities and meet FDA-grade quality standards. Our products are classified as general wellness devices. While they are not FDA-approved medical treatments, they are designed and produced in compliance with FDA manufacturing regulations for safety and quality.

Can I use the device while sleeping?

No, we do not recommend using ZORVICK cold therapy or red light therapy devices while sleeping. Prolonged cold exposure during sleep can cause skin or tissue damage. Always use the device while awake and set a timer for 15–20 minute sessions.

How often can I use cold therapy per day?

You can safely use cold therapy 3–4 times per day, with each session lasting 15–20 minutes. Always leave at least 30 minutes between sessions. If you have a medical condition such as diabetes, poor circulation, or cold sensitivity, consult your doctor before starting cold therapy.

What is red light therapy?

Red light therapy is a non-invasive treatment that uses low-wavelength red light to stimulate cellular energy production. It helps reduce inflammation, promote tissue repair, and relieve joint and muscle pain. ZORVICK red light therapy devices deliver targeted light to affected areas for safe, drug-free pain management.

Can I use the device with a pacemaker?

If you have a pacemaker or any implanted electronic medical device, do not use ZORVICK therapy devices without first consulting your cardiologist or healthcare provider. Cold therapy and red light therapy devices may generate electromagnetic fields that could interfere with pacemaker function.

How long does the battery last?

On a full charge, ZORVICK therapy device batteries typically last 2–4 hours of continuous use, depending on the temperature setting and therapy mode. Charging time is approximately 3–4 hours. The battery is covered under our 365-day warranty.
