If you want to refresh yourself, we recommend to stay in a rich natural environment in the long and medium terms without tight schedule.

Cure in a natural environment which you can rest and get exercise is most effective for maintaining balanced healthy life and lifestyle deceased prevention in our time which is closely-linked to stress.     

Ø        Basking in fresh air of the woods

We found the reason why we can relax in the woods is that phytoncide (a substance released by timber which destroy bacterium）restore a mental balance, give us liberating influence and offer us comfort by stimulating parasympathetic division.

Ø        Get negative ion

A ion (Positive and negative) is only 1/1000 mm-sized particulate which retains electricity.

In our city life, the element such as air pollution, electromagnetic wave problem and diffusion of electronic device which add positive ion have increased.

The percentage of negative ion has increased in hotspring area, since flying splay make electrical charge in the air negative.

We found when we take the air including negative ion, increased alpha rhythm of brain waves makes us relax by acting on parasympathetic division. Since negative ion is absorbed from low electric-resistive pressure points of human skin by interface activational effect, scale up our heeling properties by stimulating damaged cell, it’s said to be effective in such as relieving fatigue, shoulder discomfort, back problem, muscle ache, neuralgic pain, body circulation problem, sleeping problem, visceral disease.   

Ø        Effect of natural color

It’s well known fact that green color is good for eyes, however, you don’t give your eyes rest by such as artificial green color in TV.

In a forest without artificial light, muted natural light and green color of wood make us feel at peace.  

Ø        Get sunshine filtering through foliage

We often spend time indoors in out time, thus, we prefer to forget about getting sunshine. It helps resistance

to develop and prevent brittle-bone disease. Meanwhile, we know too much sunshine prove harmful because of excessive ultraviolet ray.

But, we can take a comfortable sun bath in midsummer since sunshine filtering through foliage is

absorbed 80% rays of the sun by rives of trees.

Ø        Rhythm of 1/f fluctuation

We have come to know that the rhythm of 1/f fluctuation are pattern of fluctuation which has unique nature being common in environment (not random, not monotony) and same rhythm of living body. This rhythm is in sound of a stream, a breath of air, age of woods and width of grain.

We can feel comfortable by rhythm of 1/f fluctuation same as body rhythm.
