You enable real research projects. Once you fund a project, you'll get access to progress, data, and results straight from the team.
Each project is reviewed by our team to make sure that it meets our project criteria. Anyone can start experimenting.

Predict and Prevent "Common cold" Smorodnikova, Evgeniya, and Alex Kostyukov.. Welltory (www.welltory.com), 3 Mar 2017. Experiment
We select 300 users that meet the following criteria:
or slightly below average BMI
§ Are not
professional athletes, but can be amateurs (jog, go to the gym, etc.)
§ Are not
seriously ill (cardiovascular disease, respiratory tract infections, brain
§ Do not
take medication that affects heart rate and blood pressure
least one ARVI since they have started using Welltory
of 3 morning measurements taken within 7 days prior to the appearance of
§ Data on
the number of hours worked, steps and sleep for the past 7 days
least 3 measurements during the illness
§ At least 3 measurements
after the illness
We interview each user, then separate them into subgroups by age
and level of physical fitness, since these factors significantly influence
within each group we analyze how HRV indicators changed during the onset and
throughout the illness, comparing these indicators to lifestyle data. We are
going to look for correlations and dependencies between indices of sick people,
build mathematical models, analyze data and track reverse trends for every
person. Thus, we will be able to figure out which lifestyle factors influence
our risk of getting sick, as well as the duration and severity of the illness.
The result will be a formula that outlines the relationship between HRV
parameters and ARVI.
