Grounding & seed cycling

Grounding (earthing): Sleeping grounded on conductive mattress pads for 8 weeks resynchronized cortisol secretion with the natural circadian rhythm, with the most pronounced effects in females (Ghaly 2004). Grounded participants showed a 63% increase in parasympathetic HRV. Grounding also produces measurable reductions in inflammatory markers. No direct fertility studies exist — the relevance is indirect through cortisol normalization, inflammation reduction, and improved vagal tone.

Seed cycling: A 1993 crossover trial found daily flaxseed eliminated anovulatory cycles (3 during control vs 0 during flax), lengthened the luteal phase by 1.2 days, and improved the progesterone/estradiol ratio (Phipps 1993). Sesame increased SHBG by 15% in a placebo-controlled crossover trial. A 2025 systematic review found favorable modulation of FSH and LH/FSH ratio in PMS/PCOS.

Important caveat: No trial has ever tested the specific rotation protocol (flax/pumpkin in follicular, sesame/sunflower in luteal) against controls. The individual seed studies support biological plausibility, but the phase-based rotation rule itself is unvalidated. Low risk, nutritionally beneficial regardless — but honest grading matters.
