Have you ever wondered why some people seem crazy about Christmas lights? This phenomenon turns into a real addiction, there are people who decorate their home with as many lights as possible, developing a compulsive behavior that they cannot get rid of. They buy lights and decorate, it doesn't seem enough; then they go back to buy lights and decorate and they are still not satisfied. But… when did this habit of decorating houses and buildings with Christmas lights come about? Albert Sadaca in 1917 was a young man of fifteen and was the first to decorate some trees with lights. It had been used for some time to decorate trees with candles, until one day some candles that adorned a tree caused a tragic fire in the city of New York so that the young man came up with the idea of using light bulbs, thinking that they would be less dangerous, so Christmas lights were born. As time passed, the lights spread from trees to houses and buildings. It goes without saying that it became a multi-million dollar business around the world. To the point that in the town of Little Rock, Arkansas, some residents went so far as to go to the state supreme court to sue the owners of a house who had placed at least 3.000.000 lights, and as you can imagine so much lighting was very good for them. annoying. But this is not the only case, in Monte Sereno in California, a couple, lovers of lights, pressured the town council to give special permission to those who wished to exhibit their lights in addition to classical time. To understand this behavior well, we must get closer to the peculiarities of these people even if it is necessary to underline that it is a phenomenon that takes on exaggerated tones, particularly in the United States and in a social class of medium-low economic level. People who exhibit this behavior usually need to call attention to themselves but indirectly, probably because they feel lonely or bored. They are simple people, unpretentious and even friendly, only that in most occasions they do not have the psychological tools necessary to start really deep friendships, so that they use the strategy of lights to attract attention and be able to start conversations. that otherwise would have been practically impossible. Digging deeper beyond obsessive behavior, a New York University biology specialist who was also fascinated by the phenomenon of Christmas lights decided to do an interview with around 3600 people. Starting from the answers received, he concluded that the way we decorate our homes is an expression of our personality This biologist suggests that those who decorate their home with few lights, without exaggerating, are emotionally balanced and extroverted people, looking for friends. Furthermore, he says that neighborhoods where neighbors have good relations are usually decorated much more than neighborhoods where neighbors hardly know each other. Wilson says it's a way people try to fit into the Christmas spirit and show their goodwill with respect to these dates. As you can see, the incidence of Christmas lights on a psychological level is still a little studied phenomenon, probably due to the short time in which they affect us.
