Why testing environment matters for accurate results:

Stress Reduction

Clinical environments elevate cortisol and heart rate. Natural settings with plants and natural light reduce testing anxiety, leading to more accurate baseline measurements.

Air Quality

Indoor plants improve air quality by filtering pollutants and increasing oxygen. Ocean breeze provides fresh, clean air. Better air quality = more accurate VO₂ measurements.

Temperature Regulation

Natural ventilation from coastal breeze maintains comfortable temperature without artificial climate control. Prevents overheating during maximal effort testing.

Circadian Alignment

Natural light exposure helps regulate circadian rhythm, important for RMR testing accuracy. Artificial lighting in windowless labs can affect metabolic measurements.

Is testing at sea level important?

Yes. Sea level provides maximum oxygen availability (20.9% O₂). Testing at altitude would show lower VO₂ max values. Santa Cruz's sea level location ensures accurate baseline measurements.

How does the ocean breeze help?

Fresh ocean air is clean, ionized, and naturally cooling. Prevents overheating during maximal testing without artificial AC. Creates comfortable environment for accurate results.

Do plants really make a difference?

Research shows indoor plants reduce stress, improve air quality, and increase oxygen levels. While the oxygen increase is modest, the psychological benefits are significant for testing comfort.

Is this as accurate as university labs?

Yes. We use the same Korr CardioCoach metabolic analyzer used in research settings. Equipment accuracy is identical-the difference is our environment reduces testing anxiety.
