You may have anticipated the gain in the hour hand every year, only to be disappointed a few months later with the need to readjust the clock by one hour again.
Some researchers have proven that the change in the hour hand which happens twice a year can cause temporary destabilization, simply because it affects your body clock.
The change in timing happens in over 70 countries where more than 1.5 billion people are affected. Because of the large population involved, one can say that it affects the health of the people worldwide.
For quite some time, there has been a debate on if it is actually necessary to change the clock. In 2017 alone, 18 states deliberated on 39 bills because of this. While some were of the opinion that the Daylight Savings Time (DST) should be adhered to throughout the year, others said that using the standard time was better.
There is no general agreement on what to do up until now, even though some states have been given concessions. For example, Arizona (not including the Navajo Nation) and Hawaii will use the standard time throughout the year. Others include Guam, Puerto Rico, Northern Mariana Islands and the Virgin Islands.
