Especially in your early years as an analyst, all Wall Streeters can expect to pull all-nighters.
Here's how it works. You're on an important project, and your boss realizes there's a mistake in the data, or the client pushes up a meeting, or you're just crashing on a deadline.
Either way, time is of the essence, you have to finish a task ASAP, and you're not going home.
Obviously, spending the night deep in excel instead of deep under your covers isn't just killer for your social life, it also hurts your body — here's what you need to know about how.

Your body elevates its levels of cortisol, also known as "the stress hormone" when you don't get enough sleep.
