Chronobiology & Lunar Biological Rhythms
Sleep laboratory studies demonstrate that during the 3–5 nights leading up to a Full Moon, human sleep onset latency increases by an average of 5 minutes and total sleep duration drops by 20–30 minutes, accompanied by measurable reductions in slow-wave delta EEG power.
Biodynamic Lunar Gardening & Sap Dynamics
Increasing moonlight and gravimetric tidal pull during waxing phases stimulate upward sap flow toward foliage and fruit, making it optimal for sowing above-ground crops. Waning phases pull moisture downward into root systems, creating ideal conditions for root vegetables, pruning, and soil preparation.
