*Why Our Gurukula Teaches to Sleep in Complete Darkness - Modern Science Agrees*
A landmark study published in the European Heart Journal on 9th September 2025 has found that nighttime light exposure may alter heart structure.
Study of 11,071 people showed that those exposed to >3 lux light during sleep had 2.4% greater heart mass and thicker heart walls - early signs of cardiac remodeling.
Lead Researcher Prof. Lu Qi (Tulane University) says: "Light pollution has emerged as a new risk factor for cardiovascular disease."
In Yoga Shastra, we call this _Tamasic light disturbance_. True _Yoga Nidra_ happens only in complete darkness.
At *Sri DurgaGurukula*, we guide our students to align with nature's rhythm for a healthy heart.
Practical Sankalpa for tonight: Switch off everything and sleep in complete darkness.
|| तमसो मा ज्योतिर्गमय || but at night, let darkness heal you.
