Non-profit cardiovascular research

How heat and light shape cardiovascular health.

Latitude Health Innovations investigates the effects of heat and the full light spectrum, from ultraviolet to infrared, on cardiovascular health.

Research studies

Our studies examine how passive heat exposure influences blood pressure and cardiovascular function. Below are our ongoing and completed studies.

Ongoing In collaboration with Michigan State University

Acute effects of Finnish sauna, sauna blanket, and sauna pod on blood pressure

A comparison of the immediate blood-pressure responses to three forms of passive heat exposure—a traditional Finnish (dry) sauna, an infrared sauna blanket, and a sauna pod—to understand how different heating modalities acutely affect cardiovascular function.

  • Finnish sauna
  • Sauna blanket
  • Sauna pod
  • Acute blood pressure

Effects of 4–8 weeks of Finnish sauna bathing on blood pressure, arterial stiffness and sleep quality

A study examining how a four-to-eight-week program of regular Finnish sauna bathing affects blood pressure, arterial stiffness, sleep quality and well-being in Black and White adults in the Lansing, Michigan, area.

  • Finnish sauna
  • 4–8 week program
  • Blood pressure

About Latitude Health Innovations

Latitude Health Innovations is a non-profit research organization. Our mission is to understand how environmental heat and the light spectrum—from ultraviolet to infrared—affect cardiovascular health, and to ensure that this knowledge reflects the diversity of the people it is meant to serve.

We design and conduct research studies, partner with academic institutions, foundations, for-profit companies and private individuals, and share what we learn with the research community and the public.

  • Heat & the heart. Sauna and passive-heat effects on blood pressure and vascular function.
  • The full spectrum. Ultraviolet, visible, and infrared light, and how they relate to health.
  • Diverse populations. Research designed to generalize across ancestries, geographies, and latitudes.
  • Open collaboration. Academic partnerships and transparent sharing of findings.
