Stress Can Prevent You From Fighting Disease

If you've been wondering why stress is bad for you, Dr Raychelle Burks, a researcher from the University of Nebraska has the answer.

She explained that, in stressful situations, adrenaline is released to help us fight or take flight. A minute or two later, Cortisol is released to sustain the effects of adrenaline.

Cortisol works by ensuring the body has a steady supply of glucose so you don't crash when the adrenaline surge ends.

If you remain stressed for long, cortisol will inhibit your immune responses making you easily prone to falling sick and delay wound healing.

Cortisol also slows bone growth (which can to fragile bones) and increases your appetite for fatty and sugary foods.

Sometimes, a bit of stress is good but too much of it can do you a lot of harm.
