In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
The discharging of sweat does not break your ghusl. However, if the excessive sweating leads to a bad odour, it is advisable to take a bath to avoid inconveniencing people around you.
And Allah Ta’āla Knows Best
