According to the doctor, most often in autumn, Russians have exacerbated cardiovascular, respiratory diseases and mental disorders.

Chronic diseases cannot be cured once and for all, but they can be controlled and stable remission can be achieved — a state when the disease does not progress and does not manifest itself in any way, the SberHealth specialist explained.

"Up to 70% of the population is sensitive to seasonal changes. For example, many patients with hypertension — high blood pressure — have to adjust their treatment regimen when the air temperature changes. It is important to regularly measure blood pressure, regardless of how you feel, in order to record its jumps in time and take measures," Permikina said.

In addition, autumn and winter are traditionally considered cold and flu seasons.

"The link between influenza and cardiovascular disease has long been proven. And the results of numerous studies demonstrate the importance of preventing flu and colds for patients with heart disease. First of all, we are talking about annual vaccination against the influenza virus. It helps reduce the risk of cardiovascular complications by 59%," the doctor said.

So-called seasonal depression is another cause of exacerbation of chronic diseases. The condition has a more scientific name: "seasonal affective disorder," or SAD. This is a subtype of depression where a depressed emotional state occurs sporadically, probably due to a lack of sunlight and an increase in the production of melatonin, the sleep hormone.

"Often SAD appears in the fall, and some people are apathetic until spring. All this has a negative impact not only on mental, but also on physical health. If you notice that your emotional state has deteriorated, consult a psychologist to make a plan of action," the RT interlocutor recommended.

Earlier, doctor Ekaterina Kashukh told in an interview with RT how to quickly return to a normal lifestyle after an illness.
