noun, noun or participle which takes 'suru', intransitive verb
caring for one's health; health maintenance
Rare, literary term for looking after one's health, often through diet and lifestyle. Modern Japanese more commonly uses 健康管理 or 養生.
加餐に努めることは、古くから養生の基本とされてきた。
Striving to care for one's health has long been considered fundamental to a healthy lifestyle.
Literary kanji compound; rarely used in modern Japanese. The reading かさん is the only reading.
The exact derivation is uncertain; the kanji 加 (add) and 餐 (meal/eating) suggest the idea of taking extra care with meals for health, but this is a rare literary compound with no clear modern usage history.
