Marina Pavlovic Rivas’ wellness essentials

Data scientist and Eli Health co-founder Marina Pavlovic Rivas developed the world’s first instant hormone monitoring system after struggling to get answers in her own health journey.

The catalyst: Frustrated by the lack of accessible hormone data, Pavlovic Rivas applied her science expertise to solve a gap affecting millions. The result: Hormometer™, an instant saliva-based test that makes real-time hormone tracking part of everyday life.

The philosophy: Just as smartwatches revolutionized heart rate and sleep tracking, Pavlovic Rivas believes personal health data should be accessible enough to create meaningful change at scale.

Her stack for healthy hormone rhythms

Philips Hue Smart Light Bulb

“I prioritize natural light whenever I can, but I often wake before sunrise and work late. Smart bulbs mimic sunrise and sunset, dim 6pm, and shut off at midnight — my final cue to go to sleep. On screens, I layer in f.lux to block blue light.”

Bota Bota Water Circuit

This Nordic-style spa in Montreal, Canada offers heat and cold year-round. “It’s become an integral part of my recovery routine,” adds Pavlovic Rivas.

Othership App

“Daily wind-down practices help calm the nervous system, reduce stress, and support healthier cortisol rhythms for better sleep.”

Hyperwear Weighted Vest

“I love hiking, and a weighted vest helps add intensity. Research shows that even 20 minutes in green space can lower cortisol, so time in nature isn’t just restorative—it helps regulate hormones too.”

EWG and SkinSafe databases

“I use EWG and SkinSafe to screen everyday products like shampoo, skincare, and makeup to avoid endocrine disruptors — chemicals that can mimic, block, or otherwise interfere with hormones.”

LMNT

“My go-to for staying hydrated because it hydrates without additives.”

Eli Health Hormometer

“I use Eli’s saliva-based Hormometer™ morning and evening to track my cortisol curve. The app translates results into actionable insights.”
