Polar H9 Heart Rate Monitor

Know Your Body. Support Your Healing.

For those living with chronic illness, fatigue, or autoimmune conditions, understanding your body's signals isn't optional — it's essential. The Polar H9 Heart Rate Monitor gives you clinical-grade heart rate and HRV (Heart Rate Variability) data so you can track how your nervous system, immune system, and energy levels respond day to day.

HRV is one of the most powerful biomarkers for monitoring stress load, recovery capacity, and overall resilience — especially for those managing conditions like fibromyalgia, ME/CFS, Lyme disease, long COVID, or adrenal fatigue.

• Accurate heart rate data — identify overexertion before it triggers a flare
• Pacing support — stay within your energy envelope to avoid post-exertional malaise (PEM)
