# Light pollution disrupts human health and wildlife, scientists warn 2026-08-10T01:57:58+00:00 | Health & Science | Indian Opinion Desk Corroboration: 1 independent outlet Artificial light at night, or light pollution, is increasingly seen as an environmental threat that disrupts human circadian rhythms and wildlife behaviour. Business Today reports that excessive or poorly directed artificial light suppresses melatonin production, linked to sleep and health, and alters animal navigation, feeding, and reproduction. A 2026 meta-analysis of 36 studies covering 30 bird species confirmed consistent effects on avian physiology, though outcomes vary. Blue-rich white LEDs pose particular risk. The problem grows with urbanisation. Plants also respond to altered light exposure, potentially changing growth and flowering. Scientists stress that artificial light affects entire ecosystems, not just individual species. The goal is not to eliminate lighting but to use correct amounts, placement, and timing. ## Coverage - businesstoday.in Tags: circadian rhythm, human health, LED lighting, light pollution, urbanisation, wildlife Canonical: https://indianopinion.org/light-pollution-disrupts-human-health-and-wildlife-scientists-warn/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
