When joints burn & ache.
Rheumatism is an umbrella term for over 400 different diseases, collectively known as the “rheumatic disease group.” These conditions primarily affect the musculoskeletal system—bones, joints, and cartilage—but can also impact muscles, ligaments, tendons, and nerves.
One of the most common rheumatic diseases is rheumatoid arthritis (RA), which causes chronic inflammation in joints, tendons, and bursae. In RA, the body mistakenly attacks its own tissues, leading to severe pain, swelling, and movement limitations. Rheumatism can gradually affect more joints and potentially cause irreversible damage.
As a result, those affected often experience a significant decline in quality of life. Even when inflammation is well-controlled, many patients continue to suffer from pain without an obvious trigger, which can be difficult to manage. Potential causes include sensitization processes, neuropathies (nerve damage), or fibromyalgia.
The good news: When diagnosed early, RA can be effectively treated—making a timely and accurate diagnosis crucial.
Below, we provide an overview of the most promising treatment approaches, ranging from medical therapies to cold therapy, which has gained increasing attention in recent years.
This is where our cooling gel, Kalter Bruder®, comes into play. Its long-lasting and powerful cooling effect provides fast relief where you need it most!

1. Pharmacological therapy
Medication is often the first approach in treating rheumatoid arthritis (RA) to control inflammation and relieve pain. Some of the most commonly used medications include disease-modifying antirheumatic drugs (DMARDs), which can reduce disease activity in the long term and help prevent joint damage. However, these medications typically take several weeks to become fully effective.
During acute flare-ups, corticosteroids can be used to provide rapid relief by reducing inflammation. However, corticosteroids should only be considered a short-term solution, as long-term use can lead to significant side effects.
Pain relievers, such as non-steroidal anti-inflammatory drugs (NSAIDs), are frequently used to quickly alleviate pain...

2. Physical & Occupational Therapy
Targeted movement and therapy are essential to maintain joint function and strengthen muscles. Physical therapy helps relieve pain, release tension, and improve mobility. Occupational therapy supports individuals in their daily lives by teaching techniques to perform tasks in a joint-friendly manner.
Light, regular exercise—such as swimming, cycling, or gentle gymnastics—promotes circulation and supports the healing process. Additionally, yoga and specific stretching exercises can help relax muscles and improve joint resilience.
Exercise is not only therapeutically beneficial but also helps prevent future flare-ups and contributes to a better quality of life.

3. The right diet
An anti-inflammatory diet can help alleviate symptoms and support overall well-being. Foods rich in omega-3 fatty acids, such as fatty fish, flaxseeds, and walnuts, are particularly beneficial due to their anti-inflammatory properties. Additionally, antioxidants found in fruits and vegetables—especially berries and leafy greens—support cell health.
Rheumatoid arthritis patients should also ensure they get enough vitamin D, which is essential for bone health.
On the other hand, it’s important to avoid excessive amounts of animal fats, sugar, and processed foods, as they can promote inflammation in the body.
A balanced diet can effectively complement the overall treatment approach and contribute to an improved quality of life.

4. Cold therapy
Targeted cold therapy can be an effective way to reduce inflammation and relieve pain in rheumatoid arthritis (RA). Applying cold helps decrease the activity of pain receptors and slows down the inflammatory process, which in turn reduces swelling and provides rapid relief.
Consistent, deep-penetrating cooling is particularly beneficial, as it reaches inflamed tissues without triggering counter-reactions in the body caused by excessive cold exposure.
While specialized cryotherapy chambers may not be accessible for everyday use, cooling ointments or gels offer a practical alternative. These can be applied directly to the affected areas, providing continuous, gentle cooling that effectively combats...
