Wellness has become a big business in European cities. Massage studios, saunas and ice baths promise lower stress, better sleep and faster recovery. Some of those claims rest on solid evidence. Others are ahead of the science. Here is what researchers have found, and how to approach these treatments with realistic expectations.
Massage: real effects on how we feel
Massage is one of the oldest forms of body care, and it has been studied extensively. Systematic reviews of controlled trials have found that massage can reduce feelings of anxiety and perceived stress in the short term, and can ease some types of muscle pain, including lower back pain, at least for a while after treatment.
The mechanism is not fully understood. Touch activates pressure receptors in the skin that are linked to the parasympathetic nervous system, the branch responsible for rest and digestion. Heart rate and blood pressure often fall during a massage. Many people also simply find focused, uninterrupted time without screens calming.
Early studies suggested that massage strongly lowered the stress hormone cortisol. Later reviews found that effect smaller and less consistent than first thought. The most reliable benefit appears to be on how people feel, rather than on measurable hormone levels.
Sauna: heat as a stressor
A sauna exposes the body to intense heat. Heart rate rises, blood vessels widen and the body sweats to cool down. In that sense, a sauna session resembles light exercise.
Some of the most cited research comes from Finland, where sauna bathing is part of everyday life. Large observational studies there have linked frequent sauna use with lower rates of cardiovascular disease and death. Because these studies observe habits rather than assign them, they cannot prove that saunas cause the benefit. People who sauna often may also differ in other ways. Still, the findings have encouraged more controlled research into heat exposure.
Saunas are not for everyone. People with heart conditions, low blood pressure or those who are pregnant should check with a doctor first, and alcohol and saunas are a poor mix.
Cold water: popular, but the evidence is still young
Ice baths and cold plunges have grown rapidly in popularity. Immersion in cold water triggers a sharp “cold shock” response: a gasp, rapid breathing and a spike in heart rate. With repeated exposure, that response becomes smaller.
Studies on cold water and mood are mostly small, and results vary. Some participants report feeling more alert and in a better mood after cold exposure. For athletes, cold water may reduce muscle soreness after hard exercise, though some research suggests it can blunt muscle-building adaptations if used straight after strength training.
The safest approach is gradual: short exposures, never alone in open water, and avoiding cold plunges if you have heart problems.
Why contrast therapy is popular
Many wellness venues now encourage alternating between heat and cold, a practice often called contrast therapy. Traditions such as the Finnish sauna followed by a lake swim, or the Russian banya with cold water, have done this for centuries. Fans describe a strong sense of alertness and calm afterwards. Scientists have only started to study the combination in controlled settings, and most trials so far are small. What is clear is that the switch between extremes places real demands on the cardiovascular system, which is why gradual exposure matters.
Sound and light: an emerging field
Some wellness centres now combine sound, vibration and light in dedicated relaxation spaces. Research on music and sound for relaxation is encouraging in general; listening to calm music has been linked to lower perceived stress in several studies. Evidence for specific devices is much more limited, so these are best approached as a relaxing experience rather than a medical treatment.
Where to try it in Amsterdam
Amsterdam has a growing range of places to explore these practices. Yskamer, on Beulingstraat in the city centre, offers sauna and ice bath sessions and is very highly rated by its visitors. It is a practical option for anyone curious about alternating heat and cold.
In Amsterdam Oost, Harmonic Egg on Halmaheirastraat offers sound and light sessions in a dedicated chamber designed for deep relaxation and stress reduction.

How to get the most out of relaxation treatments
- Set realistic goals. Most benefits are short term and depend on regular practice.
- Combine with basics. Sleep, movement and social contact do more for stress over time than any single treatment.
- Listen to your body. Discomfort during massage, dizziness in a sauna or distress in cold water are signals to stop.
- Check health conditions first. Heat and cold both place real demands on the heart.
- Choose qualified practitioners. Ask about training and hygiene standards before booking.
The bottom line
Science supports massage as a way to feel calmer and ease some muscle pain, sees promise in regular sauna use, and is still forming a view on cold water and newer sound-based therapies. None of these replaces medical care. But as part of a balanced routine, a little warmth, touch or cold can be a pleasant and evidence-informed way to switch off in a busy city.
