DST. Why does it matter? Today when my son asked me “Mom, do you know that The Daylight Saving Time is going to start on next Sunday?”. I was shocked and I said “Oh no! Don´t tell me that…”. Then I realized that I hate DST. Well, I can’t say I really hate it, but I don´t like it very much. It causes me a double feeling. When I have to wake up early in the morning and I see the darkness I feel angry, but when I leave the job and the sun is shining I feel so happy. The sensation is that I have such long time ahead to do everything I need to. Well, When I fall in my bed I realize that it's late and I say to myself “Oh, now I have little time to rest and I will wake up so early”. During the first month I usually feel confused like that. Then the time goes on and things comes back to normal routine. When I am feeling very comfortable again, the "amazing" DST is ending up. This is a cycle…. I was reading about the origin of DST and I read this idea was launched by Benjamin Franklin, American politic and inventor. But the first country which adopted DST for the first time was Germany in 1916 during the First War aiming to save costs with coal. Here in Brazil, the first DST was between 1931-1932 by President Getúlio Vargas. DST took 5 months. DST has been adopted without interruptions since 1985. Well, DST starts on October here in Brazil and ends up on February. The days are longer than usual and the lights can be turned on later. At this period we have to put our watches one hour ahead. According to researchers the country has positive results and the economy has significant benefits with it. However, older people suffer with some effects in their biological time. Everything has its positive and negative points.
