Don't be fooled by the benefits of artificial light at night

2 years ago, a colleague of mine, a doctor at the district level, suffered from insomnia, which did not help after two weeks of treatment. She asked me for screening, ultrasound, and blood tests.

After a week of not finding the cause, I gave up. After 2 years, she called back, the reason she had just accidentally found while watching a tv program, it was ALAN.

Exposure to artificial light at night (ALAN) can have a range of negative effects on animals and other creatures. For example, ALAN can interfere with the natural rhythms of animals, disrupting their sleep and feeding patterns. This can lead to increased stress and decreased reproductive success. In some cases, ALAN can also disorient animals and make them more vulnerable to predators. Additionally, ALAN can interfere with the migration patterns of some species and can affect the behavior of insects, which can in turn disrupt the entire ecosystem. Overall, the effects of ALAN on animals and other creatures can be complex and varied and can have serious consequences for the health and well-being of these animals.

For cats, ALAN can disrupt the sleep patterns of cats, leading to increased stress and decreased overall health. It can also make us more active at night, which can be dangerous if we are allowed to roam outside. Additionally, ALAN can interfere with our hunting and feeding behaviors of us, which can affect our ability to find food and maintain a healthy weight. Furthermore, ALAN can disorient cats and make us more vulnerable to predators. Overall, the effects of ALAN on cats can be significant, and it is important to take steps to minimize our exposure to artificial light at night.

We all know the problems associated with artificial light at night. It's bad for our health, it disrupts ecosystems, and it can even be dangerous in some places. But despite this knowledge, many of us still find ourselves drawn to the glitz and glamour of nighttime in a full-of-light city.

Thankfully, there is a way to have our cake and eat it too – we simply need to make sure that any artificial lighting used is properly shielded from view by using fixtures that direct light downward instead of outward or upward. This will not only reduce glare but also help preserve the natural darkness that provides such essential benefits for humans, animals, and plants alike.

In addition to shielding lights from view, we should also consider investing in LED technology which produces less heat while still providing plenty of illumination. LEDs are much more efficient than traditional incandescent bulbs so they use less energy while producing just as much brightness – perfect if you're looking to hang out late into the night without worrying about your carbon footprint!

It's a known fact that artificial light at night is not good for our health and environment, but we still want to enjoy the beauty of cities lit up in all its glory, despite our health problems. How do we get the best of both worlds?

The answer is: build entertainment cities underground.

Imagine an entire city with its own infrastructure, built beneath the surface and accessible only by elevators and tunnels. This subterranean metropolis could be filled with shops, restaurants, bars – anything you would find in a typical city above ground – but without any effect on environment. I'm sure there will be no shortage of people eager to join.

Finally, let's remember that darkness isn't something to fear; rather it should be embraced as part of nature’s cycle – nighttime is when most species rest and recharge after a long day’s work (or play!). So next time you want to experience the vibrancy of city life at night without compromising on sustainability or safety – think twice before turning on those blinding lights!
