Light pollution is a problem that has been neglected until recently. However, LED lights seem to be the first viable solution that scientists came up with to deal with its effects on our health.
Based on the latest research, spending too much time in artificial lights during nighttime might have severe consequences on our health. It has been established that 99 percent of the Europe population does not see the stars and the Milky Way.
Plus, it was discovered that light pollution affects plants, animals, and insects such as moths which can be confused by the artificial lights. As a countermeasure, the American Medical Association has warned the public about the threats of night lighting.
According to the Council on Science and Public Health, LED street lighting might be the future solution to deal with this issue. LED lights have a better light spectrum, and they do not imitate the sunshine. From a historical point of view, humans have lived around 7500 years without any source of artificial lights beside the use of fire.
Experts explained that humans switch to nighttime physiology at sunset. This process reduces hunger intensity and influences the body to drop its temperature. Also, you begin to feel the need to sleep, and the blood melatonin concentrations rise.
But when we are exposed to artificial lights for a longer period, this process is disrupted, and we sometimes feel the need to eat even at late hours. Another side-effect is that we no longer feel the need to sleep, and we are more vulnerable to develop health conditions such as cancer, heart disease, diabetes, obesity, and insomnia.
According to Richard Stevens, a medicine professor at the University of Connecticut, melatonin influences the need to sleep, and also prevents the growth of cancer tumors as it was discovered in a previous experiment.
He also added that we only need firelight, moonlight, and starlight to live healthy. The electric bulb that was invented 130 years ago changed the face of the world, but it also brought some consequences on our natural sleeping pattern.
LED lights are considered to be less dangerous than other sources of artificial light because they do not mimic the white daylight. According to experts, we should be exposed to white daylight only a couple of hours a day.
