Del Pozo Cruz stated that very excessive step counts — within the vary of 20,000 steps and past — may very well lower well being advantages.

He added that his workforce hopes to quickly replicate the research in additional various populations, as the present information set was composed of primarily white, wholesome, well-educated people between 40 and 79 years previous.
