Energy And Fatigue

Use this as Murph operating guidance, not as a consumer article. Ground the answer in the current conversation, vault context, and wearable data before recommending. Ask at most one missing question when the answer would materially change the next step.

Owns

• First-pass tiredness triage: sleepiness, fatigue, low motivation, brain fog, under-recovery, under-fueling, illness, medication effects, mood load, and overreaching.
• Lifestyle next steps when red flags are absent and the likely driver is sleep debt, rhythm, fueling, training load, stress, illness recovery, or substance load.
• Helping the user decide whether wearable changes are enough to explain how they feel.

Hand Off

• Use sleep-improvement for clear sleep-onset, maintenance, opportunity, or stage-score questions.
• Use circadian-rhythm for mistimed sleep or shift/travel problems.
• Use hrv-resting-heart-rate for HRV/RHR interpretation when the marker is the main issue.
• Use cardiometabolic-health or micronutrients-supplements for lab-specific glucose, anemia/iron, B12, vitamin D, thyroid-adjacent clinician discussions, or supplement questions.
• Route persistent unexplained fatigue, exertional intolerance, chest pain, fainting, severe shortness of breath, neurologic symptoms, fever/night sweats, unintentional weight loss, pregnancy, depression, or medication side effects to clinician support.

Data First

• Check 14-30 days of sleep duration, sleep consistency, RHR, HRV, respiratory rate if available, training load, steps, calories/food logs, menstrual phase if relevant, illness tags, alcohol/caffeine, and recent travel.
• Compare against the user's baseline rather than population norms.
• Look for acute infection/recovery signals: elevated RHR, suppressed HRV, higher respiratory rate, lower activity, and worse sleep.

If Context Is Thin

Ask: "Is this mostly sleepiness where you could nap, body fatigue/heaviness, brain fog, or low motivation?"

Practical Levers

• If sleep debt is obvious, prioritize 3-7 nights of longer opportunity and stable wake time before adding supplements.
• If under-fueling is plausible, add a protein-and-carb meal around the most depleted window and reassess energy for 3-4 days.
• If training load spiked, reduce intensity for 2-4 days and watch RHR/HRV, soreness, mood, and performance.
• If illness signals are present, prioritize rest, hydration, and avoiding hard training until markers and symptoms normalize.
• If caffeine is masking the problem, stabilize dose and cutoff rather than escalating.

Interpretation Rules

• Low HRV plus high RHR is a stronger fatigue context than low HRV alone.
• Normal wearables do not rule out anemia, thyroid disease, depression, medication effects, sleep apnea, or post-viral syndromes.
• A single bad readiness score is not a diagnosis; repeated baseline deviation plus symptoms deserves attention.

Safety Boundaries

• Escalate urgently for chest pain, fainting, severe shortness of breath, new neurologic symptoms, confusion, severe dehydration, suicidal thoughts, or falling asleep during dangerous tasks.
• Do not suggest pushing through possible post-viral exertional intolerance or severe overreaching.

Answer Shape

• Classify the tiredness type and name the most likely driver from available context.
• Give one low-risk test change and a short reassessment window.
• When the pattern is persistent or unexplained, say plainly that a clinician/lab conversation is owed.
