Light Pollution in Indian Cities Linked to Rising Health Risks
Imagine the night sky is like a clock that tells our bodies when to sleep and wake up.
Too much artificial light at night (ALAN) from city lights is messing up this clock.
This can lead to health problems like gaining weight, getting diabetes, and even cancer.
Experts are worried about light pollution, especially in cities like Bengaluru and Delhi.
Even though we know it's a problem, there are not many rules to control it in India, even though some officials are aware of the issue.
Light pollution in Indian cities is linked to increased health risks, including obesity and cancer.
Experts identify stress, disrupted sleep, and circadian rhythm imbalances as major contributors.
Bengaluru, Kolkata, Hyderabad, Delhi, and Mumbai are the most light-polluted cities in India.
Artificial light at night (ALAN) disrupts natural circadian rhythms, impacting health.
