That depends on what you do with that. You can also look at this as an investment in yourself that will substantially increase your income later. If you have something to show for it after you sabbatical, you can actually win long term.
It's entirely possible that you take a long break from work and find that you don't want to do anything. That means that you burned out completely. Just say that in an interview - that you needed to take a serious mental break, recharge, find your new orbit, and decide what you wanted to do next.
If you look for a job a bit later, it's actually easier than looking for it right after when you find yourself unemployed ;)
