2. Manage Your Stress
Stress is another thing that elevates the hormone cortisol which suppresses immune function. Keep to your deadlines, but allow yourself more time to complete projects. Leave a little early for work so you don’t have to worry about arriving on time. Limit your contact with people who are stress magnets. If you’re feeling particularly stressed, take a walk, close your eyes for 10 minutes, or open a book. Anything to break the cycle of stress and stress reactions is good.
