How moon phases influence your mood and decisions: the scientific background
Although not all scientists agree on the influence of the moon, there are several factors that explain why people believe that moon phases affect them:
1. Gravitational pull
The moon influences the tides—and humans are mostly made up of water. Some theories suggest subtle biological responses to the moon’s gravitational pull.
2. Sleep cycles
Studies show that people sleep more lightly around the full moon, which can affect their mood and decision-making.
3. Psychological expectation
Belief itself can influence behavior, known as the placebo effect or psychological priming.
4. Exposure to light
Full moonlight can affect melatonin, thereby influencing energy and emotional regulation.
Whether scientific or symbolic, this influence is deeply rooted in human culture.
Conclusion: How Moon Phases Affect Your Mood and Decisions
Understanding how moon phases influence your mood and decisions can change your outlook on life. From setting intentions during the new moon to releasing old energy during the full moon, each phase offers emotional guidance and strategic timing for daily decisions.
By aligning your goals, routines, and decisions with lunar energy, you can achieve greater clarity, emotional balance, and conscious living throughout the month.
