The hidden role of hormones in mental balance Hormones are more than biological maintenance signals—they interact dynamically with your brain to influence how you feel. Beyond the well-known neurotransmitters, hormones travel through the bloodstream to bind with receptors in regions like the hippocampus and prefrontal cortex, modulating mood, stress response,
Nature’s calming influence: hormones, blood pressure, and the nervous system Spending even 20 minutes outdoors can spark measurable changes in your body’s stress response. Researchers have observed reductions in cortisol (the stress hormone), lower blood pressure, slower heart rate, and improved heart rate variability during brief nature exposure. This aligns
