According to Alexei Katyshev, the local time (MSK + 1) negatively affects the inhabitants of the region. The doctor calculated that the geographical coordinates of Volgograd (44.3 degrees east longitude) and the Volgograd region (from 41.1 degrees E to 47.4 degrees E) allow the region to be attributed to the second time zone, which is located within 37.5-52.5 degrees E Due to the translation of the arrows in 2018, the Volgograd region began to belong to the third time zone (MSK + 1). Such time is ahead for the inhabitants of the region, moreover, it does not coincide with the geographical one. The specialist is sure that life in the third time zone negatively affects the health of Volgograd residents. For example, in adults, chronic lack of sleep increases, because they are forced to watch TV programs an hour later. In addition, in winter, due to late dawn, schoolchildren and students wake up in the dark, and this affects productivity and performance in the morning. Late sunrises in the cold season increase the likelihood of an accident, as the reaction rate of drivers decreases. In summer, the heat at local time lasts an hour longer. Sunset in May - August occurs no earlier than 19.50, maximum at 21.10, which means that the daytime summer heat (up to + 35 … +40) subsides later. In older people, this contributes to an increased risk of cardiovascular disease. In addition, Aleksey Katyshev points out gross errors in the letter "Analysis of the risk of the impact of the time calculation system on the health of the population", which is used by the defenders of the local time.
