do you incorporate any kind of rituals, practices?
I'm very interested in the Native American cultures and their concept of the Great Spirit/Wankan Tanka. I personally try to live with the seasons in mind as much as possible. As you alluded to: sleep more in the winter, less in the summer. Long hair/beard in winter for warmth; shaved face & head in summer to stay cool. Hunt/trap in the fall, plant in the spring.
I only eat meat that I harvest myself (deer, wild turkey, rabbit, squirrel, pheasant, etc), gather as much from the wild as I can (mushrooms, greens, fruits, etc), eat as much as possible from my half-acre garden, put away lots of food in the cellar and freezer for the winter months. Also make homemade wine/mead.
10 day solo retreat in the spring, 10 day solo retreat in the fall; just as many Natives went on periodic "vision quests".
What I seek from these practices is a deeper harmony with nature; a better understanding of the Great Spirit & my place in the circle of life; and to embrace death as part of life.
