Best time to take a gap year?

I have been working as a corporate lawyer for 5 years in Asia. Not gonna lie I find my job very stressful, it has taken a toll on my health and I want to take a gap year to do some studies overseas (fine arts, that’s my passion)

However everyone has been telling me not to because the market is bad and employers won’t hire me afterwards. Especially in Asia, we are expected to have no gaps between jobs.

My question is what’s the best time to do a gap year like this? I have been hearing ‘market is bad’ for 2-3 years already, and I don’t know when it’s going to end. Would it be better if I do this when I’m more experienced, say 7-10 years of experience so I’m less replaceable?
