意味

Sauna activity — the hobby of regularly going to saunas, tracking visits, and reviewing facilities.

サ活 follows the productive Japanese pattern of ○○活 (activity/pursuit), joining 婚活, 就活, 朝活 and others. It refers to the deliberate, hobby-like approach to sauna-going — not just dropping by a sauna occasionally, but actively seeking out new facilities, rating them, tracking how many times you ととのった, and sharing experiences on apps like サウナイキタイ. サ活 elevated sauna from a passive bathing activity to an active hobby with its own community, vocabulary, and culture.
