Awards season is well underway, and New York Fashion Week is just around the corner. If that doesn’t stress you out, tax season is upon us.

So, how do A-listers like Susan Sarandon and pro-athletes unwind? By floating.

Yes, you read right. And, no, it’s not what you think. Float tanks are generously-sized chambers with about 1,000 pounds of salt in about 10 inches of water. The point is to deprive yourself of all senses: You can’t see (it’s pitch black inside), you can’t hear (you wear earplugs) and you can’t touch anything (except for the chamber walls). Why would anyone ever want to do this? Good question.
