That sharp snap from a door handle is a shared winter complaint. On Japan's Pacific side the winter air is dry, and which fabrics you wear together largely decides whether you get zapped. This article explains the mechanism as people in Japan understand it, and the everyday practices used to keep the shocks down.
| Charges positive easily | ← | Middle | → | Charges negative easily |
|---|---|---|---|---|
| Nylon, wool | Silk, rayon | Cotton, linen | Polyester | Acrylic, polyurethane, PVC |
A wool jumper with a polyester lining, or nylon tights with an acrylic skirt — the closer a pair sits to the two ends of the table, the more charge builds.
[Verify] The order of the triboelectric series differs slightly between sources. Check it against material from a textile body such as the Japan Chemical Fibers Association. Check the humidity figures against the Japan Meteorological Agency's climate normals.
A spray temporarily bleeds off the surface charge, and the effect fades with time. Fabric combination and humidity are the root of the matter.
Cotton sits in the middle of the series, so it is merely less prone; in very dry air it still happens. That said, putting a cotton layer between two fabrics from opposite ends of the series is an effective way to avoid the worst pairs.
Touch a wall or a piece of wooden furniture first and let the charge drain slowly, and the sting is milder. Touching with the whole palm rather than a fingertip spreads the discharge instead of concentrating it at one point, so it hurts less.
Fabric softener (柔軟剤, jūnanzai) coats the fibre surface with cationic ingredients and suppresses charging (this is listed among its uses under the Household Goods Quality Labelling Act). Using more than the stated dose does not increase the effect.
Keeping indoor humidity at 40–60% limits static and also helps with dry skin. The Ministry of Health, Labour and Welfare's "Building Environmental Hygiene Management Standards" set the relative-humidity standard for offices and similar buildings at 40–70%.
