6/ The forest scientist, Dr. Yoshifumi Miyazaki confirmed that relaxation can be measured with one signal: heart rate variability. The same number a wearable reads on your wrist overnight.
5/ It takes very little. Ninety seconds of looking at forest imagery may lower activity in the right prefrontal cortex and tip heart rate variability toward rest.
4/ Eight weeks of meditation leaves more gray matter in the hippocampus. Experienced meditators show a quieter default mode network, the system behind mind-wandering.
3/ Forest-bathing trips can raise natural killer cell activity, a marker of immune surveillance. The effect is still measurable more than 30 days later.
