How to say "sweat" in Japanese

Choosing the right word

汗あせJLPT N3approx.Common
nounThe noun for the moisture itself — perspiration on the skin. This is the word for sweat as a thing, whether you are wiping it from your brow or drenched in it after exercise.
額がくの汗あせをふきなさい。↗
Wipe the sweat from your brow.
湧くわくJLPT N2approx.Common
godan verb, intransitive verbNot the ordinary verb 'to sweat': it describes sweat or tears suddenly welling up, focusing on how they emerge rather than on the act itself. For 'to sweat' it is seldom the word you want.
彼女かのじょの目めには涙なみだが湧わきあふれていた。↗
Her eyes gushed with tears.

Use 汗 for sweat itself, the noun; use 「湧く」 only when describing sweat suddenly welling or breaking out — it is not the ordinary verb 'to sweat', and it also covers tears springing up.
