In recent years, cold therapy has become a popular trend used by athletes, celebrities, and health enthusiasts alike. Whether through ice baths, cold baths or full-body cryotherapy — more and more people are using the beneficial effects of cold to improve their physical and emotional health. But how reliable is the scientific evidence for the often propagated benefits? We are taking a closer look at cold therapy.
The promised benefits of cold therapy
The advocates of cold therapy emphasize a variety of positive effects associated with regular cold sessions:
- Reduced inflammation: Cold is said to have an anti-inflammatory effect and thus reduce swelling and pain.
- Accelerated recovery: Athletes use cold to speed up muscle recovery after intensive training sessions.
- Improved mood: It is claimed that cold stimulates the release of endorphins and improves mental wellbeing.
- Immune system support: Regular exposure to cold could boost the immune system and reduce vulnerability to illness.
- Longer lifespan: Some advocates believe that exposure to cold may contribute to longevity by slowing cell aging.
What does science tell us?
Cold therapy may sound appealing, but which of the promised benefits are actually scientifically based?
1. Reduces inflammation and relieves pain
There is solid evidence that cold therapy can reduce inflammation and pain in the short term. Cold is used to reduce swelling, particularly for sports injuries or after intensive physical activity. Some studies confirm that cold inhibits the release of pro-inflammatory molecules such as cytokines.
2. Accelerates recovery
Ice baths and cryotherapy are often used by athletes for faster muscle recovery. Research shows that cold treatments can reduce muscle soreness and exhaustion, particularly after intensive training phases. However, the effect is highly dependent on the duration and intensity of exposure to cold.
3. Improves mood and mental health
Cold therapy also appears to have effects on the psyche. Studies have shown that cold can promote the release of endorphins and thus increase well-being. There is also evidence that cold applications could help treat anxiety and depression.
4. Strengthens the immune system
There is some evidence that regular exposure to cold can stimulate the immune system by stimulating the production of white blood cells. However, studies on this are still limited and the long-term effects of cold therapy on the immune system have not been conclusively clarified.
5. Cryotherapy and longevity
The relationship between cold and longevity is far less well researched. There are some animal studies that suggest that cold could slow cell aging. In humans, however, there is no solid scientific evidence to clearly support this thesis.
Benefits and limitations of cold therapy
Cold therapy definitely has its benefits, particularly when it comes to short-term inflammation relief, pain relief, and mood improvement. Support for recovery after sport also appears to be well documented. However, the effects on the immune system and longevity should be considered with caution, as further research is needed here.
For anyone who wants to try cold therapy, moderation is key. Cold sessions that are too long or too intense can pose health risks, particularly for people with cardiovascular problems.
Although cold therapy offers promising benefits, it is important to approach this method with realistic expectations and to pay attention to your own body's signals.
