Unlock The Benefits of Sunbathing

Mark Hurley | Nature's medicine ❖

Without sunlight, life on earth is not possible. So many processes rely on sunlight to create the building blocks to sustain life. For instance, we derive oxygen from plant matter on earth. The energy that we derive from animal products and plants comes from the sun. It would be an understatement to exclude the sun's energy as a source of hormone therapy.

There are a few reasons, as I will outline in the following sections, as to why the sun can bolster an increase in steroidal hormones. Hormones are essential for maintaining a youthful appearance, increasing energy levels, regulating metabolism, sustaining bone density, and regulating reproductive function. The steroidal hormones such as testosterone, DHEA, and estrogen are crucial for mental well being. Once these vital hormones start to decrease with age, energy levels become sapped. The good news is that the aging process can be greatly reversed by exercising frequently and obtaining moderate exposure to sunlight.



Sunlight and Vitamin D Connection

Vitamin D goes through a process before becoming activated by the liver and kidneys. Vitamin D is actually not considered a vitamin but rather a pro-hormone. It exhibits many physiological effects, including the regulation of calcium levels. Exposing the skin to sunlight creates the precursor to vitamin D. Sunbathing is a beneficial method to maximize vitamin D reserves since a larger surface area is covered. The liver and kidneys need to be functioning well to convert the inactive form (D3) into the active form of vitamin D (calcitriol).

Choline is a vital nutrient needed to support the liver and brain. Low choline levels correlate with fatty liver disease and Alzheimer's disease. Choline also supports balanced cholesterol production. The liver is the manufacturer of cholesterol production. The diet plays a marginal role with regards to cholesterol production. Poor liver health leads to high LDL levels and an imbalanced cholesterol ratio (LDL/HDL). Cholesterol supports optimal vitamin D levels.

Low levels of vitamin D increase the likelihood of cancer, lowered immune response, rickets, osteoporosis, skin disease, low hormone output, etc. The sun has so many benefits that we overlook. Of course, moderate exposure to sunlight is key. As with anything in life, "the dose yields the poison." Vitamin D levels decline with age, resulting in bone density loss. To counter the rate of decline, we should consider the following concept.

Nutrient Synergy

All nutrients and co-factors act together in synergy to optimize physiological processes within the body. Various conversion processes occur before nutrients, neurotransmitters, etc, convert into their bio-available forms. Vitamin D is no exception to this rule. The following nutrients can support the conversion of vitamin D into its active form via the kidneys.
  • Magnesium
  • Taurine
  • Vitamin K2 (mk4)
  • Choline
Magnesium has been shown to work in synergy with taurine, vitamin D, and vitamin K2 [source. Taurine not only aids the circulatory system and digestion of fats, but it helps transport magnesium ions into nearby cells to induce a physiological response. Furthermore, magnesium assists in the activation of vitamin D into its active form to regulate calcium production [source]. Vitamin k2 then transports the calcium from the bloodstream into the bones and connective tissue. Together in synergy, these nutrients support a strong core.

It is important to understand how nutrients work together because there exist many pathways before any physiological benefits can bed noted. It is not recommended to consume isolated nutrients for this reason. For instance, consuming vitamin D without magnesium or vitamin K2, leads to a depletion of magnesium and calcium reserves. this facilitates the degradation of bone and connective tissues over time.

Vitamin D - The Steroidal Pro-Hormone

Vitamin D levels are associated with higher hormone output and longevity. Low vitamin D levels lead to poor skeletal support, tooth decay, and various other related health issues. One study reported a significant increase in testosterone following vitamin D supplementation. The sun is a free source of vitamin D. Sunbathing maximizes vitamin D reserves because a larger surface area is covered.

Vitamin D and estrogen work together to facilitate bone density levels. Therefore, obtaining sufficient sunlight goes a long way to reverse the aging process. The conversion process certainly declines with age along with vital hormone levels. Once hormone levels decline, the aging process accelerates. Since the sun also helps reduce stress levels by balancing the sleep cycles and regulating certain neurotransmitters, vitamin D is considered the youthful pro-hormone.



Stimulate The Master Gland

The pituitary gland often considered the "Master Gland," plays a pivotal role in regulating hormone output. Sunlight stimulates the optic nerve of the eye, which in turn stimulates the pituitary gland in the brain. The hypothalamus is directly connected to the anterior lobe of the pituitary gland. Photosensitive cells in the eye signal the brain’s hypothalamus region to control our biological clock. This influences our circadian rhythm, which regulates hormone production, reaction time, and behavior.

The pituitary glandsecretes the precursors to hormone production such as luteinizing hormone. In males, this signals the leydig cells of the testes to secrete more testosterone. In females, luteinizing hormone triggers ovulation and estrogen release. There is a reason why more births occur during the summer months relative to winter months.

Winter tends to lead to seasonal affective disorder (depression), which can be partly attributed to reduced hormone production and neurotransmitter output. Stimulating the mind not only targets these vital hormones, but it indirectly boosts confidence and energy levels. Keeping the mind sharp will benefit us in all aspects of life.



Preserving optimal vitamin D levels will prevent the decline of mental and physical well being. The sun is a free source of vitamin D, however, the body needs certain nutrients to assist the conversion process to the active pro-hormone. Magnesium, vitamin k2, and taurine all work synergistically to maximize vitamin D reserves in the body to support growth and development. Strong bones and teeth are the outcomes of maintaining sufficient vitamin D levels. Photosensitive cells within the eyes stimulate the master hormone gland. This helps preserve hormone levels which restore youthful balance to the body.
