You frequently have bad dreams
If you spend your nights falling to your death as your teeth melt out, there’s a good chance you’re stressed. Anxiety and stress are some of the most common causes of bad dreams. Not only are nightmares an indication your brain’s attempt at processing negativity and stress, but they also disrupt sleep, and make the next day suck that much more… leading to more stress… and more nightmares. It’s a vicious cycle.
You get sick more often, and it lasts longer than you’re used to
Evolution is just the worst sometimes. Originally, your body’s reaction to stress was meant to keep you alive in “fight-or-flight” situations, as opposed to rush hour traffic.
In an actual survival situation, stress hormones cortisol and adrenaline are put to good use. In traffic and board meetings, they don’t do much more than inflame and weaken your immune system. During prolonged stress, cortisol stops doing its normal job of regulating immune cells, thereby increasing your chances of getting sick and staying sick longer. Doesn’t matter if it’s bacterial, viral, or even stronger allergies, stress can cause chronic inflammation and really break you down.
