Why do I always get sick on holiday?

Exhaustion

When your PTO finally arrives, you’re starting things off with an empty tank. You’ve been busting your butt at work for weeks in prep for your time away from the office, and you prioritized all of your social commitments over self-care because you knew the spa would soon be within reach. While neither of these choices are bad ones, they do leave you feeling pretty spent at the very beginning of your trip. Between stress and a lack of sleep, your immune system is already partially compromised.
