How well your body recovers from stress. Higher = better recovery. Your nervous system's "bounce-back" score.
How to improve: Better sleep (#1), Zone 2 cardio, morning walks, magnesium before bed.
COMT A;A means slower cortisol clearance — exercise is how you clear it.
How hard your heart works when you're doing nothing. Lower = more efficient heart.
How to improve: Zone 2 cardio (#1), daily walking, hydration, less caffeine after 2pm.
How much oxygen your body can use during exercise. Higher = better endurance. Strongly linked to longevity.
How to improve: Zone 2 cardio (sustained effort), progressive run training, consistency over intensity. You peaked at 35.46 in Feb when cardio was regular.
Total sleep AND deep sleep matter. Deep sleep is when your body repairs muscle and clears stress hormones.
The link: Exercise → deeper sleep → better HRV → better recovery. Your data confirms this pattern. The 4-day gap broke the cycle.
How to improve: Exercise daily (#1), bed by 10:30pm, magnesium, no screens after 10pm.
| Level | Range (ms) | You | What It Means |
|---|---|---|---|
| Excellent | 60+ | Elite recovery. Your nervous system bounces back fast. Typical of serious athletes and meditators. | |
| Good | 48–59 | Strong parasympathetic tone. Your body handles stress well and recovers overnight. This is your target. | |
| Average | 35–47 | Normal for your age. Room for improvement through consistent cardio, better sleep, and stress management. | |
| Below Average | 20–34 | ◄ 27.3 | You are here (Mar 26). 27.3 ms — below average but meaningfully higher than the prior AutoSleep estimate (14.6 ms was overnight passive reading; H10 morning measurement is more accurate). Week has been inconsistent: two 38.2 peaks (Mar 20, 24) bookend a multi-day trough. Sleep debt is real but nervous system isn't in crisis. Consistent 7h+ nights will push this into Average range. |
| Low | <20 | Critical low. Chronic stress, severe sleep debt, or overtraining. With COMT A;A, getting here means stress hormones have fully compounded. |
| Level | Range (bpm) | You | What It Means |
|---|---|---|---|
| Athlete | <50 | Elite cardiovascular efficiency. Heart pumps more blood per beat. Common in endurance athletes. | |
| Excellent | 50–59 | Very strong heart fitness. Likely running or cycling regularly at moderate volumes. | |
| Good | 60–64 | Solid baseline. Your heart doesn't have to work hard at rest. This is the near-term target. | |
| Average | 65–74 | ◄ 72 | You are here. Normal range but higher than ideal. Consistent Zone 2 cardio (walking/light jog at conversational pace) is the most reliable way to drive this down. Your Marine background means the engine is there — it just needs mileage. |
| Above Average | 75–84 | Heart is working harder than needed at rest. Usually responds well to regular exercise. | |
| High | 85+ | May indicate deconditioning, chronic stress, or medical conditions. Worth discussing with a doctor if sustained. |
| Level | Range | You | What It Means |
|---|---|---|---|
| Superior | 46+ | Top 5%. Exceptional aerobic capacity. Longevity research links VO2 Max above 40 to significantly reduced all-cause mortality. | |
| Excellent | 40–45 | Well above average. Strong aerobic base. This is where longevity benefits become significant. | |
| Good | 36–39 | Above average. Your body efficiently delivers oxygen during exertion. Your Feb peak of 35.46 was knocking on this door. | |
| Fair | 31–35 | ◄ 33.2 | You are here. Average aerobic fitness. Peaked at 35.46 (Feb 18) when cardio was more consistent, now declining — likely from the 3+ week dance pause and reduced cardio volume. Walk-jog progression starting Mar 23 should reverse this trend. ACTN3 T;C genotype means you're wired for both power AND endurance. |
| Poor | 25–30 | Below average. Limited aerobic capacity. Even light exercise can feel demanding. | |
| Very Poor | <25 | Significant deconditioning. Associated with increased health risks. |
