If you get something done on time, it doesn’t really matter if you procrastinate, right? This video from Men's Health will make you think twice about putting anything off.
When you have a project with a looming deadline (especially one that's due, say, tomorrow), your body reacts by producing different hormones that ramp up your heart rate and cortisol levels. Usually, cortisol keeps white blood cells in check, but frequent procrastination makes your body less sensitive to the stress hormone. That allows the white blood cells to go bonkers and cause inflammation. Even worse? Constantly producing cortisol requires a lot of energy, so your body stores up fat (a form of energy) around nearby organs. And that can lead to heart attacks. Bottom line: Try not to put it off, if you can.
