The research behind everything MPC tracks alongside your pain — explained in plain language, with an honest rating of how strong the evidence actually is.
You've always suspected it. Cold fronts. Pressure drops. Thunder storms. Your body responds to things your doctor may never mention. This Science Centre explains what the research says — and MPC lines those same factors up against your own logged days so you can see whether they hold true for you.
Some of these factors have real research behind them. Some have barely any. We don't hide that — every one carries an Evidence rating so you know what you're looking at before you draw a conclusion. A flat result is a finding too.
Marked Live if it's in the app today, In development or Coming soon if it's being built, Planned if it's on the list. We won't call anything live until it actually is.
The weight of the air — it drops before storms. The most-studied weather trigger there is.
Heat, cold, and damp. Often move together with pressure — captured for your ZIP code each time you log.
The moon cycle. Widely believed, thinly supported — so we stay neutral and just show you your data.
Optional, and entirely on your device. Hormonal shifts are one of the best-documented pain triggers — and one of the least tracked.
Solar storms and geomagnetic activity. Early research, growing interest. In development — not live in the app yet.
Earth's electromagnetic "heartbeat." Fringe science — we'll track it so you can judge for yourself, not because we're sold on it.
Seismic activity near your ZIP code. A future factor some users have asked for.
Each page covers the biology, the peer-reviewed evidence, and how MPC uses the data — with full academic references.
The most commonly reported weather trigger across all chronic pain conditions. How falling pressure expands tissue against sensitised nerve endings — and why the rate of change matters more than the absolute value.
Cold and humidity are the most consistently reported weather triggers in research. The cold + wet combination is worse than either alone — and MPC's Temperature-Humidity Pain Index (THPI) captures exactly that.
For decades, medicine studied one average body — usually a man's — and dosed everyone else off it. The record on that, why it still matters, and how cycle tracking fits into MPC.
Not all chronic pain responds to weather the same way. Detailed trigger profiles for fibromyalgia, rheumatoid arthritis, osteoarthritis, migraine, chronic back pain, and neuropathic pain — with evidence ratings.
Solar flares, coronal mass ejections, geomagnetic storms — and the emerging, still-unsettled research on how they might reach the body. Not live in MPC yet; the page explains where it stands.
Plain-language definitions for every scientific and technical term used across the Science Centre — from Kp Index and TRPM8 to central sensitisation and the THPI. Searchable and filterable by category.
We're not here to sell you the moon or debunk it. Every one of these is just an input we line up against your own logged days. Here's your data. You decide what it means for you.
Every factor MPC tracks is here because there's research worth pointing at — and we tell you plainly when that research is thin. We don't invent correlations. We record what the world was doing each time you logged, and show you the two side by side.
The more days you log, the more there is to see. Your thresholds, your lag times, your quiet factors — from your data, not a study cohort's.
Professional-grade conditions captured for your ZIP code every time you log — not a guess, and not your phone's GPS.
Your pain isn't average. MPC lines your logs up against each factor so you can see for yourself what tracks and what doesn't.
Your log stays on your device. Nothing shared without your explicit action.
