Immune Resilience Baseline: Four Lifestyle Factors
7 consecutive days of real-time logging (2–5 min per day) + 30 min to calculate averages
Immune resilience — the ability to resist infection and recover quickly from illness — is primarily determined by four measurable lifestyle factors: sleep quality and duration, physical activity level, dietary quality (particularly micronutrient density), and acute stress load. None of these requires clinical measurement; all can be self-assessed using standard NHS-referenced tools and logged in real time. Establish a 7-day baseline across all four. Sleep: record total sleep duration in hours and subjective sleep quality (1–5 scale: 1 = very poor, 5 = excellent) each morning. Physical activity: record daily steps or activity minutes (a phone pedometer is sufficient). Dietary quality: record a simple 3-day diary midweek and count average daily servings of vegetables and fruit (5-a-day target) and oily fish servings per week (NHS target: 2 per week). Stress: record daily perceived stress on a 1–5 scale (1 = very calm, 5 = highly stressed) each evening. Average all four dimensions across the 7 days and identify which dimension is furthest from its target.
Proof required
Submit your 7-day immune resilience baseline: daily sleep duration and quality (1–5), daily step count or activity minutes, 3-day food diary with daily vegetable and fruit portion counts, and daily perceived stress score (1–5). Calculate 7-day averages for each dimension and identify the primary gap.
What gets checked
- All four dimensions are recorded in real time for 7 consecutive days — retrospective recall at the end of the week systematically underestimates stress scores and overestimates sleep quality; the diary must be recorded each morning/evening as instructed
- The 3-day food diary is midweek (not a weekend if weekday eating habits differ) and covers all meals and snacks — the vegetable and fruit count requires full-day coverage to be accurate
- One primary gap is identified — the dimension furthest from its NHS-referenced target is the focus for the 8-week programme; the M3 comparison will be most meaningful against this primary gap

What a verifier looks for
- All four dimensions must be present for all 7 days. If any dimension is missing for more than 2 days, ask whether those days were omitted or just not submitted — the 7-day average requires complete data for each dimension
- The 3-day food diary should be midweek, not weekend. If the submission dates the diary to Saturday–Monday, ask whether weekday patterns were also logged at any point in the 7 days
- One primary gap should be identified. If the submitter names all four dimensions as gaps without prioritising, ask which single dimension they will focus on in the 8-week programme
- Recording sleep duration without sleep quality — duration and quality are both needed because 7 hours of fragmented sleep has different immune effects from 7 hours of uninterrupted sleep; both must be recorded
- Using weekend days as the 3-day food diary period — weekend dietary patterns (takeaway, alcohol, irregular meals) differ systematically from weekday patterns and would produce an unrepresentative baseline; use Monday to Wednesday or a normal working week
- Conflating stress score with bad events — the stress score should reflect the felt stress level, not the number of difficult events; a day with three hard meetings may be rated 3 (manageable) if the person felt calm; a quiet day may be rated 4 (high) if anxiety was elevated regardless of events
Eight Weeks Improving the Primary Immune Resilience Gap
8 weeks (3-day weekly logs, 5 min per day; weekly averages at Weeks 2/4/6/8)
The 8-week programme focuses specifically on the primary gap identified in M1 — not all four dimensions simultaneously. Research consistently shows that single-behaviour change is more sustainable than multi-behaviour change; addressing the primary gap produces the largest immune resilience improvement for this person at this time. Choose one specific, concrete change to make in the first two weeks of the programme, based on the primary gap. Common starting points: if sleep duration was below 7 hours, set a consistent bedtime 30–60 minutes earlier and a consistent wake time; if vegetable and fruit servings were below 3/day, add one serving to two meals per day; if perceived stress averaged above 3/5, introduce a 10-minute daily wind-down practice (walk, breathing, journalling). Continue logging all four dimensions weekly (3 days per week) throughout the 8 weeks to track the primary dimension and monitor the others. Calculate weekly averages for all four at Weeks 2, 4, 6, and 8.
Proof required
Submit (1) 3-day per week logs for all 8 weeks covering all four dimensions (sleep duration and quality, activity, vegetable and fruit servings, perceived stress); (2) weekly averages for the primary dimension at Weeks 2, 4, 6, and 8; (3) a brief description at Week 4 and Week 8 of the specific change made and whether it was maintained.
What gets checked
- 3-day per week logs are recorded in real time across all 8 weeks — spot-checking 3 days per week (not just the best days) is the minimum for a representative weekly average across the 8-week period
- Weekly averages for the primary dimension show a trend across the 8 weeks — the goal is sustained improvement, not a single good week followed by reversion
- The specific change made is named at Week 4 and Week 8 — 'I moved my bedtime from midnight to 11 pm and have kept it' is specific; 'I tried to sleep more' is not

What a verifier looks for
- The logs must cover 3 days per week for all 8 weeks. If any weeks are missing entirely, ask whether those weeks were not logged or just not submitted
- The weekly averages for the primary dimension should show a trend. If the averages show no change from M1 to Week 8, ask what specific change was made and why it may not have affected the average
- The specific change named at Week 4 and 8 should be the same change (or a clear evolution of it) — switching to a completely different change mid-programme without noting why suggests the original change was abandoned
- Logging all four dimensions to perfect targets for the first 3 weeks then abandoning the diary — perfectionist starts often lead to abandonment when the person misses a target; the programme requires consistent realistic logging, not perfect performance
- Changing the primary dimension focus mid-programme because another dimension looks worse — the 8-week programme was designed around the primary gap identified in M1; switching focus partway through means neither dimension gets a full 8-week intervention
- Recording only good days and omitting days when sleep was poor or stress was high — the 3-day weekly average must include representative days, not cherry-picked ones
Final Immune Resilience Comparison and Attestation
7 consecutive days of real-time M3 logging (2–5 min per day) + 30 min to compile comparison table
At Week 8, record the final 7-day diary using the same method as M1 — all four dimensions, real time, 7 consecutive days, midweek food diary. Calculate final 7-day averages for all four dimensions and compare to M1 in a side-by-side summary table. The primary dimension should show clear improvement from M1. Provide an attestation from one named person who observed the 8-week lifestyle changes — a household member, close colleague, or exercise partner who can describe what specifically changed in the primary dimension.
Proof required
Submit (1) M3 7-day diary (real time, 7 consecutive days) covering all four dimensions; (2) a side-by-side comparison table showing M1 and M3 7-day averages for all four dimensions; (3) an attestation from a named person who observed the lifestyle changes, specifically in the primary dimension, across the 8 weeks.
What gets checked
- M3 diary covers 7 full consecutive days recorded in real time — using the same method as M1 makes the before/after comparison valid
- The comparison table shows all four dimensions at M1 and M3 — even if only the primary dimension was targeted, all four should be compared to show whether the focused change affected the others
- The primary dimension shows a clear improvement from M1 in the M3 average — this is the direct result of the 8-week programme's focused change

What a verifier looks for
- The M3 diary must cover 7 full days recorded in real time using the same format as M1. If the M3 submission shows only 3 days or appears retrospective, ask for the full 7-day diary
- The comparison table must show all four dimensions. If only the primary dimension is compared, ask for the full table — secondary changes are part of the outcome evidence
- The attestation should describe observed change in the primary dimension specifically — 'they were in bed by 10:30 every night for the last 2 months, which they never were before' is observation; 'they said they were sleeping better' is not
- Using only 3 days for M3 rather than the full 7 days — the M1 baseline was 7 days; a 3-day M3 comparison is not on the same basis; the full 7-day diary is required
- Selecting the best week of the 8-week programme as the M3 week instead of the final week — the M3 diary should be the last 7 days of the programme, not the best performance week
- Providing an attestation from someone who only observed the final week and not the beginning — the attesting person must have been present at both the beginning and end of the 8-week programme to describe change
