At Palasiet Thalasso Clinic & Hotel, we believe in the harmony between medical science and natural wellness. Diathermy is one of those therapies that blends both worlds — a deep, soothing heat treatment that not only helps your body recover but also invites you to relax from the inside out. Whether you’re seeking relief from muscle tension, supporting joint health, or enhancing your overall wellbeing, diathermy offers a gentle yet powerful way to feel renewed.

If you’re wondering what is diathermy and how it could be part of your wellness journey, this guide will give you the answers.

What is Diathermy?

Diathermy is a therapeutic technique that uses controlled electromagnetic waves to generate heat deep within your body’s tissues. Unlike surface warmth from a hot compress, this treatment penetrates into muscles, joints, and connective tissue, helping them relax and recover.

The term comes from the Greek dia (“through”) and therme (“heat”), meaning “heating through,” which beautifully describes how it works. At Palasiet, diathermy often complements our thalassotherapy treatments and other wellness spa therapies to create a complete restorative experience.

How Diathermy Works: The Science Behind the Therapy

When you ask how does diathermy work?, the answer lies in gentle physics. The therapy delivers high-frequency energy into targeted areas, causing tiny molecular vibrations that produce soothing internal heat.

There are three main types of diathermy you might hear about:

Shortwave diathermy – reaching deeper muscle and joint tissues.
Microwave diathermy – focusing heat on more superficial tissues.
Ultrasound diathermy – using sound waves for therapeutic and recovery purposes.

In the hands of our trained spa team, this scientific process becomes a deeply relaxing wellness ritual.

Therapeutic Benefits of Diathermy for Wellness and Spa Treatments

Within Palasiet’s personalised programs, diathermy therapy can offer:

Muscle relaxation after travel, sport, or daily stress.
Improved circulation, helping tissues receive more oxygen and nutrients.
Pain relief for stiff joints or chronic muscular discomfort.
Deep relaxation that calms both body and mind.

We often integrate diathermy into sea water therapy sessions for enhanced effects, taking advantage of the healing properties of our Mediterranean environment.

Diathermy Procedure: What to Expect During Your Session

Your diathermy session begins with a friendly welcome and a short conversation about your goals. You’ll be positioned comfortably while the device is applied to the treatment area, often with a soft cloth or gel for comfort.

Guests typically describe the sensation as a pleasant, penetrating warmth — never too hot, just deeply relaxing. Sessions usually last 15–30 minutes. Afterward, you may notice improved mobility, lighter muscles, and a renewed sense of energy.

Is Diathermy Safe? Potential Risks and Precautions

When performed by qualified professionals, diathermy therapy is safe and non-invasive. It’s not recommended for certain conditions such as pregnancy, pacemakers, metal implants in the treated area, or specific medical issues.

Our team always performs a quick health check to ensure diathermy is right for you before starting. Safety and comfort are at the heart of every session.

Best Practices and Tips for Enjoying Diathermy at a Wellness Resort

For the best results from your diathermy treatment:

Stay hydrated before and after.
Combine it with other therapies like therapeutic massage or hydrotherapy pools.
Communicate with your therapist about temperature and focus areas.
Allow time to rest afterwards to fully integrate the benefits.
