Cold shower
The easiest way into cold training — turn the tap to cold for 30 seconds at the end of your warm shower.
Execution
- Shower warm as usual, then turn the tap to its coldest setting.
- Start with feet and legs, then arms, and finally chest, back and neck.
- Breathe out slowly and steadily instead of gasping for air.
- Begin with 30 seconds and build up slowly over weeks; two to three minutes are plenty.
- Afterwards dry off, dress warmly and move around until you warm up on your own.
Tips
- The cold-shock feeling is strongest in the first 30 to 60 seconds — after that it gets noticeably easier.
- In Movepath, log only the cold phase as the duration, not the whole shower.
- With heart or circulation conditions, high blood pressure, Raynaud's or during pregnancy, check with a doctor first.
Cold without an ice tub
The cold shower is the most accessible form of cold training: it costs nothing, needs no equipment and you can stop at any moment. Tap water in Central Europe runs at roughly 8 to 18 °C depending on the season — much colder in winter than in summer. Because the water only ever hits part of your skin, the load is far lower than with full immersion. That is exactly what makes the cold shower the right starting point before you think about ice baths or winter swimming.
What happens in the body
Cold water on the skin triggers a stress response within seconds: breathing becomes faster and deeper (the typical gasp reflex), heart rate and blood pressure rise, and the blood vessels in the skin constrict. The body releases noradrenaline, which many people experience as feeling awake and clear. With regular repetition the body gets used to the stimulus — the cold shock becomes weaker and it is easier to stay in control of your breathing.
The largest controlled study on cold showers (Buijze et al., 2016, around 3,000 participants in the Netherlands) found that 30 days of 30 to 90 seconds of cold water at the end of a shower led to about 29% fewer sickness absences from work — but no difference in how many days people were actually ill. Participants stayed home less often but did not get sick less often – an effect on how people felt, not on the immune system. Promises such as a "stronger immune system" or "fat burning" go beyond this evidence.
Progression
- Weeks 1–2: 30 seconds of cold at the end of the shower — legs and arms only if the whole body is still too much.
- Weeks 3–4: 60 seconds, now including chest and back. Keep your breathing deliberately calm.
- Weeks 5–6: 90 seconds to 2 minutes. Everyday practice does not need more than two to three minutes.
Do not progress faster than you can calm your breathing. If you are still gasping after two minutes, stay at one minute for now.
Safety
- Not medical advice. Cold is a real strain on the circulation. With heart or circulation conditions, heart rhythm disorders, high blood pressure, Raynaud's syndrome, cold urticaria or during pregnancy, talk to your doctor first.
- Not straight after hard strength training if building muscle is your goal — strong cooling right afterwards can blunt the adaptation. A gap of a few hours solves this.
- No alcohol beforehand, and not when you are already chilled, ill or exhausted.
- Stop if you feel dizzy or numb, shiver uncontrollably or have pain in your fingers and toes.
- Warm up gradually: dry off, warm clothes, movement — not straight into the sauna or under very hot water.
