Science of Safety Measures

On our Stay Safe page we outlined the measures we have put in place to best ensure your safety.

These measures were based on the findings of scientific research in to COVID transmission.

This page explains the science behind the safety measures in our studio and our Hot Yoga classes.

The Science Part

This research shows that speech droplets generated by asymptomatic carriers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are increasingly considered to be a likely mode of disease transmission. Highly sensitive laser light scattering observations have revealed that loud speech can emit thousands of oral fluid droplets per second. In a closed, stagnant air environment, they disappear from the window of view with time constants in the range of 8 to 14 min, which corresponds to droplet nuclei of ca. 4 μm diameter, or 12- to 21-μm droplets prior to dehydration. These observations confirm that there is a substantial probability that normal speaking causes airborne virus transmission in confined environments.
 
That’s 4 micro metre when the particle has dehydrated and 12-21 when it’s still hydrated.

Research shows that a heat of 56°C kills the SARS coronavirus at around 10000 units per 15 min (quick reduction).

Our hot yoga studio delivers classes at 42°C, which is as close as possible to a temperature that kills the virus.

We are confident that heat in a (well-ventilated) room helps to reduce risk.

Research shows that between 40-60% relative humidity can be ideal in reducing the likelihood of airborne transmission.

Unlike others in the industry, our unique heating system allows us control over the humidity in the room. Our Hot Yoga classes are taught at 50% humidity, this short video from BBC also helps to explain how that’s a good thing.

Previously, on a Teacher Training weekend, a qualified Scientist and University Lecturer conducted tests on our Hot Yoga machine. The results showed that our heating system replaces the air in the room at a rate of 50 times an hour. This means the air that gets filtered as explained below is replaced 50 times an hour!

Our heating system uses G4 filters with 90% arrestance.  A G4 filter is designed to remove particles ≥10μm. So, only dehydrated Covid particles can get into the room. Because the air is drawn from a large and very quiet car park, there are no fumes and it’s unlikely that there are any COVID particles as there is no one out there.

Finally – we have added in a second layer of air filtration to the hot studio as well as every other room in the studio. Read the point below for information about that.

On our safety with Yogafurie page, we explain how we have invested in air filtration for each and every room. These filter air droplets as small as 0.3μm in size.

We have one in each room, including in the Hot Yoga studio.

This means anything that may be missed by our heating unit can be picked up and filtered by the dehumidifier in the room, meaning that we have an extra layer of safety whilst practicing Hot Yoga.
