Doctor Ana Perez Ballesta has warned that the habit of using your phone before bed can have serious health consequences. Her words are quoted by El Confidencial.
As Ballesta explained, between 10 and 12 p.m., cortisol levels are at their lowest. As a result, a person's vigilance and self-control decrease, and the brain enters a resting phase, in which it is more vulnerable. This is when people usually use their phone. Moreover, they plan to spend only a few minutes on gadgets, but often they unnoticed turn into hours.
“And so we find ourselves in an endless scroll, and our brain does not find the right moment to say: “That’s it, it’s over,” the doctor noted. If this scenario is repeated day after day, the person’s sleep quality may deteriorate. In addition, this habit negatively affects emotional regulation and mood, ultimately causing depression and anxiety, the specialist emphasized. “Perhaps the best strategy is not to rely on your willpower to fight the algorithm every night, but to not take your phone into the bedroom at all,” she added.

In the 38th week of 2026, 734 thousand cases of ARVI, influenza and COVID-19 were registered in Russia, which is 33.8% higher than the previous week, reports Rospotrebnadzor.

In Russia, a new GOST has been developed for powdered milk formulas for baby food from the first year of life, which will come into force on January 1, 2027 and will replace the 1998 standard. Formulas should be a fine powder from white to light cream in color, with a protein composition as close as possible to breast milk, and the packaging should contain a warning about the preference of breastfeeding without images of children.

In Russia, the epidemiological situation with ARVI, influenza and COVID-19 is developing as predicted, but the intensity of the spread of respiratory infections is increasing. Rospotrebnadzor is developing a test system for the simultaneous detection of 30 types of acute respiratory viruses.

Rospotrebnadzor recommends that children, elderly people over 60 years of age and people with chronic diseases, including diabetes and cardiovascular pathologies, as well as medical workers, social workers and trade employees, and teachers, be vaccinated against influenza first.

Professor Murad Shakhmardanov said that the 'unusual cold' without fever can be caused by known respiratory viruses such as rhinovirus, coronaviruses, metapneumovirus, adenoviruses and bocaviruses, and that the emergence of a new virus with a different clinical picture requires genetic changes or zoonotic transmission, which are not observed in the current situation.
