Recovery, Measured.



More than a decade of focused research has shaped the way Dr.Friend approaches recovery. From foundational studies to controlled human research, we continue to examine the conditions that support better rest, balance, and everyday recovery.

THE EVIDENCE JOURNEY


From Scientific Questions to Measurable Evidence                                  



Recovery begins with understanding.

Dr.Friend develops its research through a step-by-step process—from building

a scientific framework to examining mechanisms, evaluating human outcomes, and expanding the evidence through publication and follow-up studies.

 



FOUNDATION


Building the Research

Framework


Collaborations with universities,

hospitals, and research institutions

help establish the scientific

framework for recovery research.








MECHANISM


Understanding How

Recovery Works


Preclinical studies examine

physiological responses related

to sleep, stress, inflammation,

and the recovery environment

under defined conditions.






HUMAN RESEARCH


Evaluating Real-

World Outcomes


Controlled human studies

evaluate measurable sleep- 

and stress-related outcomes.








ACADEMIC EXPANSION


Publication 

and Follow-up


Peer-reviewed publications and

follow-up studies expand the scope

of the evidence and create new

questions for continued research.

FEATURED HUMAN STUDY


Sleep and Stress, Examined Together           

                    




                     A 30-day randomized, double-blind, placebo-controlled

                        study involving 56 participants evaluated sleep-

                        and stress-related measures.


                 Within the test group, the study reported lower scores

                        in sleep quality, insomnia severity, and perceived stress

                        measures after the study period.


                 On day 31, actigraphy indicated a significantly

                       longer sleep duration in the test group compared

                        with the control group.
