I'm a good sleeper until I get stressed. Instead of quickly nodding off to my soothing white noise machine, I'll lie awake for an hour thinking about everything I have to do, then wake up from stress dreams. Instead of sleeping straight until my alarm, I'll bolt awake in panic, hours early, for no apparent reason. I need all the sleep I can get when I'm stressed, but it's when I'm stressed that I just can't get it.

It’s cold and flu season. You know that, because it seems like just about everyone is sick. Your office is cut in half. The receptionist at your dentist’s office is sick. Your mom just called, and she’s sick, too. While the entirety of North America seems to be battling nasal drip, there’s another problem. The holiday travel season is upon us, meaning all of that sneezing, coughing and aching will be boarding a plane with you.

Fatigue can keep you from making healthy food choices or exercising regularly.

A successful workout program requires tracking and progression, says Brynn Jinnett, owner of Refine Method in New York City. By keeping tabs of your fitness, you'll be more inclined to improve it. Create a baseline fitness test, making sure to include moves that measure the strength of all of your major muscles. Maybe you gauge things like the number of pushups you can do, how long you can hold a plank, how many lunges you can do in 60 seconds, and how long you can hold a wall squat. Then make it your goal to beat those numbers one month from now.
