What’s Wrong With the DST?

DST is setting forward clocks during the standard time. Basicly it’s the seasonal time changing. Firstly, George Vernon HUDSON, who is a bug collector, presented a paper. It was proposing shifting two hours twice in a year. That was interesting idea, but noone followed him. After a decade William Willett suggested shifting 20 minutes totally 8 times in a year, independently from Hudson. It was used more and more day by day. Today, fewer than half of the countries in the World and over than 1 billion people actually use it. As anyone can guess, there are many advantages beside the disadvantages.
The first advantage of DST is having more sunlight during a day. People do their works in daylight, so DST provides more efficient time with them. On the other hand, according to newest researchings, an avarage person, sleeps 40 minutes less after the time shifting. Because of this situation productivity drops down in the few days after clock setting. so, most of people suffer from this adaptation process.
Secondly, people have to wake up earlier. It is an opportunity to order sleeping periods. People can use it to be more creative or hardworker. Otherwise, , changing the time, even if it is only by 1 hour, disrupts our body clock. Human body may affected negatively. For example, last studies Show that, first Monday of DST has 25% more heart attack than a typical Monday.
Finally, as it was mentioned before, changing the clocks does not create extra daylight, but it causes the Sun to rise and set an hour later time. So, when we set our clocks in spring, we add 1 hour of natural daylight to our typical afternoon schedule. So extra hour can be used for extra activity like basketball or spending time with family. In addition turism endustry would be affected positively.
To sum up, although DST has benefits, there are many bad effects. 70 countries use it today nearly. On the other side, many countries ignore this technic. Both sides have valid reasons for apply DST or not. In any case countries have to consider their conditions for DST.
