Water/air temperature [floatation tanks]

on controlling and/or predicting optimal per-customer water/air temperatures in float tanks

Transcript

1. Water/Air temperature Individually for each floater
2. Contents - Issue Overview - Best practices on Water/air temp - Individual differences - Simple hacks (?) - What it depends on and can we predict in advance (?)
3. Intro: float tanks & temperatur We aim for: Neutral feel = not cold nor warm No thermoregulation (no sweating, no shivering) ~100w produced at resting, which need to be removed high humidity impedes heat removal from body
4. My experiences Bad: 36C water in Swiss, close to overheating, headache Bad: <25-30C air, salt crystallizes - hurts One of best centers in US - too hot for me, sweating: water+air was 35.0 C / 95F (I prefer 34.2C/93.5F) Float On – nice float they use 34.15C / 93.5F water, warm up only when needed
5. Standard / best practices Water & air at 34.1-34.2C / ~93.5F (Lower optimum) & ask clients move less while floating some use <35C / 95F (too hot for me!) Humidity <= 80% Ventilated and heated air Try to match water temp to average skin temperature (?)
6. Simple Hacks Ask to take a cold/hot shower: too hot -> take hot shower too cold -> cold shower ? Suboptimal: If can’t control air temp, change water temp: e.g. too cold air -> raise water temp to ~35C / 95F (example in Vilnius, Lithuania)

8. Temperature perception Depends on: - Humidity - Starting skin temperature (?) Characteristics of the local cutaneous sensory thermoneutral zone http://jn.physiology.org/content/117/4/1797
9. Air is easier to control Change air temp Sometimes just opening tank lid while taking a shower is enough! Samadhi had a “cold emergency” button to heat the air
10. What it depends on & Can we predict it? Don’t know the answer yet, but some ideas: - Humidity - Skin temp ? - Did sports recently? - Stressed? - Cold hands / legs - Hot or cold shower? - Is it hot outside?
