Biologists named the most dangerous time of the day

A new study conducted by experts from Cambridge University, show that malicious viruses are much more active in the morning and on the order of “effective” than at any other time of the day. The same thing, according to scientists, applies to vaccines.

During the experiments, the scientists infected laboratory animals with influenza virus and herpes at different times of day, then watched infect the virus of their media. As it turned out, the most vulnerable to the effects of infection the animals were in the morning at this time, the virus was more effective than ten times. According to scientists, this trend was primarily evident in case if the infection carrier regularly slept at night, if his “biological clock” was shot down, the probability of infection increased significantly not only in the morning.

Unlike bacteria and parasites, the virus is completely dependent on the work they infected cells (this is one of the reasons why most of the scientists do not recognize the virus in a form of life). However, the cells themselves at different times behave differently. Fluctuations in the intensity of processes occurring in them, occurring over a twenty-four hour cycles are called “circadian rhythms”. They affect 10 percent of all genes in an organism and, although this “internal clock” is very useful from an evolutionary point of view, viruses have learned to use to their advantage.

Experts checked out its conclusions on just two types of viruses, but the findings they tend to be a rather universal, since the flu viruses and herpes are completely different types, but circadian rhythms “help” them equally, and therefore, the same may be valid for the vast majority of other viruses.

According to the researchers, the fact that the disturbance of circadian rhythms makes living creatures more vulnerable to infections, be aware of people working in shifts or in different reasons often changing time zones. In General, the findings, as expected, the experts will help to find the most effective ways of combating epidemics.

The scientists published their work in the journal of the journal Proceedings of the National Academy of Sciences.
