What is driving it
Each factor's current level, from 0 to 100, and the science behind it.
Dry air, especially when cold, pulls moisture out of the skin and weakens its barrier. This is the strongest and most consistent eczema trigger for most people. Read from dew point, humidity, temperature, and wind.
When it is both hot and humid, sweat lingers on the skin and its salts can irritate an already sensitive barrier. Dry heat behaves differently and is captured by the dry-air factor.
Fine-particle and gas pollution (PM2.5, PM10, NO₂, ozone) add oxidative stress to the skin barrier. The link is well supported, and it builds over several days rather than acting the same day.
Airborne grass pollen can trigger flares, but mainly for the subset of people whose eczema is linked to allergies, so it carries a smaller weight.
Contrary to common belief, sun is not a reliable help for eczema, and research has linked more sun exposure to worse control. We give it only a small, cautious weight.
What this means today
Dry air is the main stress today. Dermatology groups commonly suggest moisturizing right after bathing, running a humidifier when indoor air is dry, and using lukewarm rather than hot water.
General education, not personal medical advice. What actually helps you is best worked out with your own clinician.
Air quality now
Fine-particle pollution measurably worsens eczema, and it builds over several days, so a run of hazy days matters more than one.
