Dark Skies

Enjoy the Night – Protect Our Skies, Wildlife, and Wellbeing

Imagine stepping outside and seeing the Milky Way arching overhead, owls gliding silently through the dark, and bats weaving gracefully under a canopy of stars. The night sky is a shared treasure — for us, for wildlife, and for future generations.

Unfortunately, excessive artificial light is making the night less magical, disrupting nature, and even harming our own wellbeing.
But here’s the good news: we can make a difference tonight — simply by rethinking how, when, and where we light our homes and gardens.

Why It Matters

• Wildlife thrives in natural darkness
  Many nocturnal creatures, like bats, moths, hedgehogs, and owls, depend on darkness to hunt, navigate, and rest. Artificial light can confuse their instincts, disrupt migration, and reduce their food sources.

• Humans need darkness too
  Over-lighting can interfere with our natural sleep cycles, and studies show it can impact physical and mental health.

  A 2024 study introduced the Night Sky Connectedness Index (NSCI). It found that individuals who felt more connected to the night sky scored higher in measures of mental well-being and happiness—showing a clear link between natural darkness and emotional health.

• Stars are vanishing from view
  Astronomers and stargazers are losing access to the wonders of the night sky due to unnecessary lighting. By reducing glare and skyglow, we bring the stars back.

Bright Light ≠ Better Security

It’s a common belief that bright floodlights improve safety — but research shows otherwise. Poorly designed lighting can create deep shadows where intruders can hide, and glare can make it harder to see.

• LSHTM/UCL study in the Journal of Epidemiology & Community Health (2015) — Using data from 62 councils in England & Wales (2010–2013), the authors found “no evidence of an association between reduced street lighting and increased crime.”

• A study in Chicago revealed crime rates fell when streetlights were dimmed at night.

The real key to security? Smart lighting — motion sensors, downward-facing lights, and just the right brightness.

Simple Steps for Starry Nights

1. Light only where needed – Aim lights downwards, not into the sky.

2. Use motion sensors or timers – Keep lights on only when necessary. Sensors are better of the two.

3. Choose warm, low-brightness bulbs – Less glare, less disruption. See softlights.org

4. Shield your lights – Prevent spill into neighbours’ gardens and wildlife habitats.
