#cortisol
The coffee to your brain!

Cortisol is your stress hormone, we all have daily stresses that bombard us.

Which cause this hormone to increase throughout your day, Increasing its amount in your bloodstream and therefore we may find it hard to wind down at night.

Regular #chriopractic adjustments decrease your cortisol levels.

If you're not sleeping well, you are prone to sickness.

Your body needs #rest.

🩺🥼The spine has an exceptional memory. 🩺🥼

Your spine will remember and become used to your posture. This is why it can be hard to get out of the habit of having bad posture. But once you do make a habit of good posture, your spine will remember it.
