My resting heart rate is 85 bpm — should I be worried?

A resting heart rate of 85 bpm in a man over 40 is at the elevated end of the normal range and is associated with approximately 50–70% higher cardiovascular mortality compared to men with resting heart rates below 70 bpm in cohort studies, warranting investigation of modifiable causes (low aerobic fitness, excess caffeine, elevated cortisol, subclinical thyroid disease, anemia) and a targeted aerobic training program as the primary intervention (Perret-Guillaume et al., Rev Med Interne, 2009).

Before attributing a high resting heart rate entirely to fitness, your physician should check: thyroid function (hyperthyroidism raises resting heart rate), CBC (anemia raises heart rate through compensatory mechanism), sleep quality (untreated sleep apnea chronically elevates resting heart rate through sympathetic activation), caffeine intake (more than 400 mg/day contributes), and cardiovascular structure (rare but important). In most men 40–55 without these conditions, a resting heart rate of 85 bpm means the heart is working harder at rest than it needs to, primarily because it is not conditioned to be efficient.

Honesty Scale: Solid (1) for elevated resting heart rate as a cardiovascular mortality risk factor in observational data.

What to do: Rule out the treatable medical causes (thyroid, anemia) with a simple blood test at your annual physical. Then build consistent aerobic training. A 3-month commitment to 150 minutes per week of zone 2 aerobic exercise typically reduces resting heart rate by 5–15 bpm, moving a man from the elevated-risk zone toward the lower-risk range.
