The Silent Sleep Saboteur
How everyday noise steals our rest and health - and what Quiet India is doing about it
Noise & Sleep Loss Connection
In India, noise pollution doesn’t have to fully wake you to disturb your sleep. Even sounds you don’t consciously register – like a late-night honk in Mumbai, a dog barking in Delhi, or a neighbour’s loud TV – can silently disrupt rest by causing:
- Micro-arousals (brief awakenings you won’t remember)
- Spikes in heart rate and blood pressure
- Increased stress hormone release
- Reduced time in deep, restorative sleep
Our brains are evolutionarily wired to scan for danger even during sleep. In noisy cities, this constant subconscious vigilance means many Indians wake up tired, drained, and unrested, even after a “full” night’s sleep.
