SUMMER IS COMING! Get that sun to your skin and get more energy (mitochondria)
The Importance of Sun Exposure
Light deficiency is another extremely common cause of fatigue. Sun exposure triggers vitamin D production, which is important, but it also has many other functions and benefits that can directly impact your energy level.
For example, the vast majority of melatonin, some 95%, is produced in your mitochondria in response to sunlight (specifically red near-infrared light, which is what provides warmth). Melatonin is a potent anti-inflammatory, so sunlight allows you to target oxidative stress right where it’s needed the most.
“Melatonin is absolutely vital for protecting your mitochondria from harm and preventing them from accumulating damage as you age,” Whitten says. But swallowing melatonin is useless for this, as oral melatonin cannot reach the mitochondria.
Red and infrared wavelengths also stimulate tissue-specific growth factors. So, in muscle cells, it increases insulin-like growth factor 1, which is a key growth factor for muscle growth. In your thyroid, it stimulates growth factors that help regenerate thyroid gland tissue in the brain.
In your skin, fibroblasts are stimulated by red and near-infrared light to increase collagen production. So, essentially, red and infrared light act as signals that trigger growth and regeneration at the cellular level, throughout your whole body.
Factors That Influence Your Energy Levels:
While mitochondrial dysfunction is a central issue in fatigue, other factors also come into play, including:
Low muscle mass — Greater muscle mass contributes to metabolic flexibility and health, because muscle acts as a sink for glucose, thereby reducing your risk of insulin resistance. Low muscle mass, on the other hand, is a leading contributor to early death, and it’s a major contributor to low energy and fatigue
Elevated blood sugar and insulin resistance — This primarily goes back to a poor diet high in processed foods and constant grazing throughout the day. Eating a whole food diet and implementing TRE can go a long way toward normalizing your insulin and blood sugar
Lack of hermetic stress such as insufficient amounts of exercise
Stress
Poor gut health
