Let’s talk about stress and cortisol. I’ve seen many people get on the right track with their diet and exercise—but they're still stuck in fight-or-flight mode. 
Being in fight-or-flight mode, having elevated cortisol and adrenaline, for a long period isn’t healthy. 
Chronic stress has been known to negatively affect the body in many ways, including: 
 • Shrinking your grey matter
 • Shrinking your thymus gland
 • Creating muscle atrophy 
 • Decreasing testosterone 
 • Running the body on sugar (even when you’re not eating sugar)
 • Disrupting healthy digestion
 • Reducing quality sleep 
Chronic worry and stress can also lead to ulcers, inflammation, and disease.
An interesting study measured 39 people’s cortisol levels before and after a 45-minute art therapy session. This study found a significant reduction of cortisol in participants.
I have found that hobbies are a fantastic way to stop the fixation on stress and move your attention to something more positive.
