It's amazing just how much Nature does for us; the list of benefits is nearly endless, so on this occasion - a little bit about the healing frequencies of forests. Trees have been used in healing for thousands of years in cultures throughout the world, and lately we have been learning a lot about the power of sound waves created by trees and plants is general - plant bioacoustics.
The audible sound that is perceptible by us has frequencies from about 20 to 20,000 Hz, and everything above is ultrasonic (high-pitched sound waves). Plants emit frequencies between 10 - 240 Hz as well as ultrasonic sound waves within 20 - 300 kHz. These healing frequencies are known to convert beta brainwaves to theta and alpha brainwaves.
Brainwaves are electrical impulses in the brain. The classic names of these EEG bands are delta, theta, alpha, beta, and gamma. Our minds mostly reside in a beta state (13 - 30 Hz), but too much beta activity, particularly high beta, can make us anxious, distracted, and eventually can weaken our immune system due to an excess of stress hormones production (cortisol adrenaline, and noradrenaline). Frequent stress, especially prolonged or chronic stress and elevated levels of stress hormones reduce our body’s natural response to foreign hazards such as bacteria and viruses.
Alpha (8-12 Hz) and theta (4-8 Hz; theta occurs most often in sleep) brainwaves are active when our mind is in a state of relaxation. They help us to bring the anxious or distracted mind and body to a much needed state of calm and concentration.
So find your little forest area, or immerse yourself in our lush forests when time comes, and spend some time surrounded by trees without an agenda, simply slow down and let your senses take in the healing frequencies and freshness of Nature. It's worth every effort to set aside just 2 hours per week for this free forest therapy; the soothing therapy that lowers our heart rate and stress hormones, strengthens our immune system, boosts our natural killer cell activity, and improves our mood. Nature heals as nobody can!
