“During heat exposure, half to nearly three-fourths of the body's circulation shifts from the core to the skin to facilitate sweating. In a typical Finnish-style sauna session, for example, a person can expect fluid losses of one or two pounds (0.6 to 1.0 kilograms) per hour.”

“Whereas the innate immune system — the first line of defense — involves barrier functions, such as those provided by the skin, the adaptive immune system includes distinct cell types that work together to neutralize the virus.”

“Its synthesis occurs in a stepwise manner that begins in the skin following exposure to ultraviolet light and ends in the kidneys with the production of 1α,25-dihydroxyvitamin D, or 1,25(OH)2D, the active steroid hormone.”

“Fructose absorption begins in the epithelium (i.e., skin-like cells) of the small intestine, which measures approximately 320 square feet in surface area (about the size of a small studio apartment).”

“Exposure to ultraviolet (UV) light is critical for maintaining many aspects of human health. For example, compounds present in the skin react to UV light, initiating the production of vitamin D, a steroid hormone that participates in many physiological processes.”

“Still, the findings suggest that, for many people, simply eating more fruits and vegetables may not be enough, and that adding flavanol-rich foods to the diet may be necessary to reach levels linked to health benefits. In this clip, I highlight the health benefits of cocoa flavanols for circulation, cognition, and skin, plus my dosing insights.”

“Environmental exposures influence the integrity of the blood-testis barrier. Biological barriers play important roles in protecting tissues and organs from harmful environmental exposures. Examples of such barriers are found in the brain, retina, placenta, skin, and testes.”

“Subcutaneous fat tissue lies just under the skin and is generally considered metabolically less harmful than visceral fat. Both groups experienced lower resting heart rate and lower diastolic blood pressure. Body mass index decreased modestly in both groups.”

“For example, growing up in an overly hygienic environment increases a child's risk for developing autoimmune diseases, but exposure to dirt, especially from soil, pets, and roaches, in the first year of life may provide protection against asthma and allergy-related skin disease.”

“Opioid drugs are highly addictive due to their effects on the reward-seeking centers in the brain. Previous research suggests sunbed tanning may be addictive in ways similar to effects of opioids. Exposure to ultraviolet (UV) light causes the skin to produce vitamin D.”
