*(If the Sun is weak, or if Saturn is in that house (the 1st house), in such a case it gives the native a Vitamin D deficiency.)*
Dr. Sharma shares a brilliant piece of Medical Astrology, connecting planetary placements directly to physical health.
In astrology, the Sun (Surya) represents the bones, vitality, and the literal sunlight that gives us Vitamin D. The 1st house (Ascendant) represents the physical body.
Dr. Sharma explains that if the Sun is weak in the chart, or if Saturn (the planet of darkness, coldness, and the enemy of the Sun) sits in the 1st house, it blocks the solar energy from reaching the physical body. This astrological blockage manifests medically as a chronic deficiency of Vitamin D ("Vitamin D ki kami"), leading to bone issues, lethargy, and low immunity.
