免疫力

• 読み: めんえきりょく
• ローマ字: men'ekiryoku
• 漢字の分解: 免 (exempt, escape) + 疫 (epidemic, plague) + 力 (power, strength) → immune power/strength
• 発音: /meɴ.e.ki.ɾjo.ku/

意味

Immune system strength; the body's ability to fight off illness and infection.

免疫力 became one of the most discussed health terms in Japan, especially during and after the COVID-19 pandemic. The concept of 'boosting' one's 免疫力 through diet, exercise, sleep, and supplements drove massive consumer interest. Health shows, products, and supplements constantly reference 免疫力アップ (boosting immunity). While immunologists note that 'boosting' immunity is oversimplified, the term remains central to everyday health discussions.
