Low-Pressure Headaches Spread on 5ch: ‘Feels Like My Head’s Being Hit With a Hammer’

From our other sites

The story

On 5ch’s “News VIP” board, a rainy-morning chat thread called “Sulking Nap Club,” featuring emoticon characters, was started. Participants posted one after another about low-pressure headaches and fatigue, unrealized gains on semiconductor stocks, a typhoon approaching Chiba, and everyday topics like dentist visits and laundry. Replies sympathizing with the complaint “Feels like my head’s being hit with a hammer, maybe because of the air pressure” piled up, and the ongoing rainy-weather malaise became the thread’s main topic.

( `・Δ・´)I sold my semiconductor-related
investment trust, and
the next day it jumped
about 7%.
Missed out on around
¥400,000 in profit.

Background and Discussion Points

The sensation described in the thread — “my head hurts, maybe because of the air pressure” — is medically known as weather-related illness (kiatsu-tsū, or “barometric headache”), a phenomenon in which changes in air pressure are thought to stimulate the inner ear, throwing the autonomic nervous system out of balance and triggering headaches and fatigue. That said, figures like “30 days of low pressure straight in Tokyo” are exaggerations based on posters’ personal impressions, not official Japan Meteorological Agency data, and should be read with that caveat. “Sulking Nap Club” is also the informal name for a recurring chat thread on News VIP that uses emoticon characters; it isn’t tied to any particular incident or news story, but exists mainly for posters to narrate and share everyday small talk about weather and daily life as it happens. The way topics like unrealized gains on semiconductor stocks, dentist visits, and laundry are interspersed reflects the casual, live-narration feel typical of this kind of thread.
