How does meditation improve overthinking and sleepless nights?

The Astrological Reading: Ritesh, as a Sagittarius, you are a seeker, but being born late at night means your Moon is highly active during the hours of darkness. Your "What-If" loops are a result of your fiery Sagittarius energy having nowhere to go at night, so it turns inward and burns through your peace of mind. The Detailed Solution: There is a direct connection between your breath, your anxiety, and your sleep. When you overthink, your breath becomes shallow, signaling your brain to stay awake for a "threat." Meditation breaks this connection by activating the "Parasympathetic Nervous System." Before bed, practice "The 4-7-8 Technique": Inhale for 4, hold for 7, exhale for 8. This long exhale is a biological signal for sleep. It quiets the "What-If" chatter by shifting your brain from "Problem Solving" mode to "Rest and Digest" mode. The Remedy: Remedy Solution: Use Lavender oil on your pulse points before your bedtime meditation. Direction: Ensure your head is facing South while sleeping to align with the Earth's magnetic field for deeper rest. Mantra: Chant "Om Agasthi Shayana" silently as you lie down to invite sleep.
