4 Farada Spa — Spa treatment reference: session | 4faradaspa.com
The sauna is hot and dry, the steam room and hammam are warm and saturated: 80–100 °C at 5–15 % humidity against 40–45 °C at nearly 100 %.
The Finnish sauna is the hottest room on the menu: 80–100 °C with humidity held at just 5–15 %. The air is dry, sweat evaporates quickly, and the limiting factor is simply how long the heat can be tolerated — which is why rounds are capped at 8–15 minutes.
The steam room sits at the opposite corner: 40–45 °C but humidity close to 100 %. Sweat cannot evaporate into saturated air, so the body sheds heat poorly and 45 °C of steam can feel heavier than 90 °C of dry sauna air.
A hammam belongs to the steam family. Plan for the steam-room range — roughly 40–45 °C and near-total humidity — rather than sauna temperatures, and keep the same round discipline.

The safe protocol has the same shape for both rooms: 8–15 minutes inside, 10–20 minutes of cooling outside, repeated for two or three rounds. Fifteen minutes of sauna heat can release about 0.5 litres of sweat, so 500 ml of water before and after is the standing rule.
The water side completes the circuit: hydrotherapy pools at 34–36 °C for relaxation, hot tubs at 37–40 °C, and contrast therapy alternating 15 °C cold with 40 °C hot in 1–3 minute stages.
Durations for every treatment are sorted on the duration chart, and the arrival, hydration and cooling steps are laid out in the preparation checklist.
