eli5: How does stress cause physical health issues?
In: Biology
All stress has a physical aspect – adrenaline and quicker heart beat, among other things, to make us more alert and effective at handling whatever stresses us, be it a lion chasing us or a deadline.
That’s good, but our bodies and organs aren’t made to work on that level for long, and it wears out. Wear and tear is more common at that level of activity, and you give it no chance for a rest to “repair”.
