Wat het is

A simple heat practice in which the feet, from the ankles down, are placed in warm water. It is often easier at home than a full bath, and has been used for cold feet, tiredness, and winding down before sleep.

Korte inleiding (geen behandelvoorschrift)

1. Pour comfortably warm water (around 40°C as a rough guide) into a basin or a foot-bath vessel. The water should not feel scalding.
2. Keep the feet covered above the ankle for 10 to 20 minutes. Add warm water if it cools.
3. When the aim is sleep, it is often done about an hour before bed.
4. Dry the feet afterwards and put on socks so they do not cool quickly.

Onderzoeksnotities (dit is geen belofte van effect)

B: Er zijn gerandomiseerde studies of systematische reviews, maar de berichten zijn bescheiden, de doelgroep is beperkt, of de kwaliteit van het onderzoek is beperkt

Several systematic reviews and meta-analyses from 2024–2025 have reported improvements in older adults’ subjective sleep quality after a warm foot bath before bed. Evidence on objective sleep measures is still weak. This does not show a treatment effect on cardiovascular disease.
