Blue light can make it hard for you to sleep, so don't look at your phone or computer before you go to sleep. According to a new study published in Science Advances, that problem may extend beyond your personal beauty sleep to a larger, environmental scale.

The researchers found that the more energy efficient and higher visibility lights are rapidly replacing the old school sodium lights for outdoor use in Europe, bringing with them some unforeseen but drastic consequences.

All categories were negatively affected by the suppression of melatonin, star visibility, and insects' response to light. The level of melatonin suppression in humans has gone up since the beginning of the year.

The researchers say that the trend is increasing the risk of harmful effects.

Blue light is thought to affect melatonin production. It is not hard to imagine why that may have adverse effects for humans as well as animals.

What are the benefits ofLED? Are they worth the trouble? Researchers don't think so

They state that the benefits that LEDs may provide for public lighting, and particularly street lighting, have been vaunted.

Warming lights would illuminate the night without disrupting the environment. We'll have to wait and see if we should stick with older sodium lights or just switch to warmer LEDs.

Energy-saving light bulbs are contributing to light pollution.

There are environmental risks from artificial nighttime lighting.
