The endocrinologist spoke about the effect of spring on hormones and mood

Spring revival, increased energy, and increased emotional sensitivity are phenomena that many associate with mood, but they are based on very specific physiological processes. Lidiya Bindyukova, an endocrinologist at Invitro, told Izvestia on May 10 about how the change of season affects the human hormonal system and behavior.

According to the expert, spring changes in the body are directly related to an increase in daylight hours. This is one of the key biological factors that regulates human biorhythms and affects the functioning of the endocrine system.

"The body reacts to changes in the photoperiod, and this is reflected in the hormonal background. With a decrease in melatonin production, drowsiness decreases and activity levels increase, and increased sunlight promotes the growth of serotonin, which affects mood and stress tolerance," explained Bindyukova.

She noted that the hypothalamus, the central regulator of the endocrine system, is also activated, which amplifies signals to all organs and systems, increasing the overall tone of the body. The air temperature also has a separate effect. Warming helps to expand blood vessels and improve blood circulation, which reduces the energy consumption of the body and promotes the growth of physical and social activity.

Speaking about seasonality in behavior and interpersonal relationships, the doctor emphasized that biological rhythms do affect the emotional state, but their manifestations are complex.

The formula of desire: why maturity turned out to be the main age of men's sexual activity

Scientists have found that men are most sexually active at the age of 30-40 years.

"In spring, it's not so much the peak of hormonal activity that is more often observed, as behavioral activation — increased sociability, initiative and desire for new acquaintances. In men, spring changes are more often expressed in reducing stress levels and increasing initiative, while in women cyclical hormonal changes related to the reproductive system and estrogen levels are more noticeable," she noted.

Bindyukova also explained that the feeling of "falling in love" is associated with the work of neurotransmitters — dopamine, norepinephrine and other substances responsible for the brain's reward system. Spring conditions create a favorable background for their activation.

The doctor emphasized that it is possible to support natural processes through simple habits — regular sleep, sufficient exposure to daylight, physical activity outside, a balanced diet with enough protein and reducing stress levels.

"Spring does not create an artificial surge of emotions, it rather removes the winter inhibition of the body and makes us more susceptible to external stimuli," the specialist concluded.

Kirill Masliev, Candidate of Medical Sciences, member of the State Council Commission "Long and Active Life", Head of the Department of Preventive Medicine at the Rudn University, said on April 7 that human health cannot be determined by one indicator, since the body is a complex interconnected system. According to him, several factors play an important role at once: the balance of vitamins and trace elements, the absence of chronic inflammation, normal hormone levels and blood pressure, as well as a balanced diet, physical activity and quality sleep.
