Those microbes can release certain neurotransmitters that can induce certain neurochemical signals via the vagus nerve – which can influence your moodTip! Try the 3-2-1 rule for better sleep: stop eating 3 hours before bed, avoid liquids 2 hours before bed, and cut screens 1 hour before bedWhen dealing with pain: remember, that pain is modulated by what you thinkOur obsession with screens is changing the shape of our eyes! We have a short-sightedness epidemic
Tip: every 20 minutes, give your eyes a break and look out into the distance; this is good for your eyes and activates your parasympathetic nervous system (rest & digest)Don’t underestimate the power of experiencing awe; even a beautiful sunset can have meditative effects on your mind & body
