Hormone Synthesis

Laughter supports hormonal health. Women in the Joovv study had increases in progesterone while maintaining balanced progesterone-to-estrogen ratios. Men experienced significant increases in free and total testosterone after daily full-body exposure. All steroid hormones, including estrogen, progesterone, testosterone, and cortisol, are synthesized from cholesterol and fat. Both emotional states (laughter, worry) and environmental light signals directly modulate hormone output. Early results suggest light therapy may increase DHEA and support progesterone production, but the data remain preliminary. Restricting fat intake deprives the body of the raw material needed to produce steroid hormones. Inadequate fat consumption can directly cause low sex drive, menstrual irregularities, and poor stress response. Sleeping in darkness is essential for proper hormonal function. Daily full-body red and near-infrared light therapy is discussed as a research focus for hormone health.
