If one is exhausted or cold while in the nature, one coukd try this

 If in winter time you get cold or exhausted while outdoors on a skiing trip, and likewise in the other seasons while walking in nature, in principle you could look at a tree branch, maybe at the height corresponding a feeling of your head in a winter hat, or somewhat liwer, and see the atmosphere of the branch, how the tree endures weather, lives well in the eeather, copy that atmisphere, that way of tuning tl lufe, to the nature, to moving, to stsying warm, to preserving forces for near future situatilns and further away too, and see how the heat regulatiln and ways of living use space to stay warm and forces to return heat and endure long with the help of the ease brought by admiring the beauty of nature. And see how the tree endures the four seasons, what is a wise way to live them, and cooy that too to your basic way of living. So you can be strong andwell prepared for future, enjoy life and the beauty of nature, living a quite ordinary lufe anyway. Sometimes such succeeds, sometimes not, and I do not know whst it depends on. 

If you have hurt yourself, a hurt feet isn't steady basic structure like a branch or a leaf. Instead the atmosphere in the air near a branch or a plant is often atmospheric in a sensitive airy way that is good influence for your body and mind to get healed, with full health as a goal, and continuing walking or skiing another goal of importance.
