Chiang Mai room health

Mold, Humidity, Sleep & Indoor Air

Rainy season changes the room around you. If your sleep, breathing, morning energy, or mental clarity changes with it, measure the environment before buying another supplement.

Measure before you guess.

My first question is simple: do you feel or sleep differently somewhere else? A change away from home is a clue, not proof that mold is the cause.

  1. Measure humidity. Check before bed, on waking, inside closets, and behind furniture. The US EPA recommends keeping indoor relative humidity below 60%, ideally between 30% and 50% when feasible.
  2. Look for moisture. Check leaks, condensation, musty smells, the visible parts of the air conditioner, mattress and bed base, curtains, rugs, walls, and porous furniture.
  3. Change one variable. Test dry mode, a dehumidifier, an air-conditioner cleaning, removal of a damp item, or a HEPA air purifier. Track the room reading alongside sleep quality and morning energy.

An air purifier can reduce airborne particles. It cannot repair a leak, dry wet material, or remove growth from a surface. Fix the moisture source first.
