Cortisol prevents the release of chemicals that strengthen your immune system. That's why you tend to get sick when you're stressed out. Too much cortisol essentially suppresses your immune system and decreases your ability to fight infection.
Stress also makes you more susceptible to diseases that you rely on your immune system to hold at bay or eradicate, like cancer. Men have a pretty quick rebound from the cortisol release during stress, but women often sense a lingering impact of the hormone, which is why men are so chipper the day after a lover's spat that they have already forgotten it, while women retain perfect recall of the event, together with the emotional undertones.
