Note - from October 29 to October 30, we change the lazy time to winter time.

Although 84% of Europeans in a survey conducted by the European Commission on a record-high number of respondents (as many as 4.6 million people) are in favor of abolishing time changes, we will continue to change the clocks. The next switchover from summer to winter time will take place this weekend, from Saturday to Sunday. Time changes affect the economy. The Japanese calculated that using daylight saving time could reduce carbon dioxide emissions by 400,000. tons and help save up to 930 million liters of fuel. In addition, it contributes to the reduction in the number of street thefts by 10%. Savings are particularly noticeable in logistic systems - where a shift work system is used or in electronic systems conducting financial transactions on a global scale. A study of electricity consumption in the state of Indiana (USA) showed that residents' electricity bills increased after the introduction of daylight saving time. On the other hand, research conducted in California proved that in this state the change of time does not cause changes in the demand for electricity. Daylight saving time arrangements were introduced by European countries in the 20th century with the aim of saving energy, particularly in times of war and the oil crisis of the 1970s. Time changes and its impact on our health. Changing the time during the first few hours increases the level of cortisol in our bodies. It is on these days that the risk of a heart attack or stroke increases. This is due to the reaction of our body to a disturbance in the routine, different times of getting up and forced to go to bed at a different time.
