“Green Exercise Is Exercising Outdoors or in Nature“.
BENEFITS TO EXERCISING OUTDOORS
- Fresh air has more oxygen.
- Greenscapes raise serotonin levels
- Triggers primal regions of our brain and psyche.
- More sensory stimulation.
- Increases feelings of well-being and lowers depression.
- Sun exposure increases Vitamin D levels and helps optimise hormones.
- Vitamin D refers to a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, iron, magnesium, phosphate, and zinc. In humans, the most important compounds in this group are vitamin D3 (also known as cholecalciferol) and vitamin D2 (ergocalciferol). Cholecalciferol and ergocalciferol can be ingested from the diet and from supplements. Very few foods contain vitamin D; the synthesis of vitamin D (specifical cholecalciferol) in the skin is the major natural source of the vitamin. Vitamin D is made in the skin from cholesterol-dependent on sun exposure (specifically UVB radiation). Vitamin D from the diet or dermal synthesis from sunlight is biologically inactive; activation requires enzymatic conversion (hydroxylation) in the liver and kidney. Evidence indicates the synthesis of vitamin D from sun exposure is regulated by a negative feedback loop that prevents toxicity, but because of uncertainty about the cancer risk from sunlight, no recommendations are issued by the Institute of Medicine (US) for the amount of sun exposure required to reach vitamin D requirements. Accordingly, the Dietary Reference Intake for vitamin D assumes no synthesis occurs and all of a person’s vitamin D is from food intake. As vitamin D is synthesized in adequate amounts by most mammals exposed to sunlight, it is not strictly a vitamin and may be considered a hormone as its synthesis and activity occur in different locations.[misleading] Vitamin D has a significant role in calcium homeostasis and metabolism. Its discovery was due to an effort to find the dietary substance lacking in rickets (the childhood form of osteomalacia). Beyond its use to prevent osteomalacia or rickets, the evidence for other health effects of vitamin D supplementation in the general population is inconsistent. The effect of vitamin D supplementation on mortality is not clear, with one meta-analysis finding a decrease in mortality in elderly people and another concluding no clear justification exists for recommending vitamin D – WIKIPEDIA
- VITAMIN G or Riboflavin, also known as vitamin B2, is a vitamin found in food and used as a dietary supplement. As a supplement it is used to prevent and treat riboflavin deficiency and prevent migraines. It may be given by mouth or injection. It is nearly always well tolerated. Normal doses are safe during pregnancy. Riboflavin is in the vitamin B group. It is required by the body for cellular respiration. Food sources include eggs, green vegetables, milk, and meat – WIKIPEDIA.
- WILL – Will power.
