Tatyana Molostova, an expert doctor at EGENY, explained that after winter, the body's biological clock requires adaptation, which can lead to sleep problems.
According to Molostova, circadian rhythms that regulate sleep depend on the change of day and night, as well as the time of year. In the absence of daylight, the level of serotonin in the brain decreases, which is responsible for wakefulness and motivation, while the synthesis of melatonin, which promotes sleep, increases. With the transition to the spring period, when the daylight becomes longer, the biological clock may shift, which also affects sleep quality.
She emphasized that during the winter months, when the daylight is shorter, the level of melatonin remains elevated even during the day, leading to a state of constant fatigue and apathy. Sleep problems at the end of winter are not a figment of imagination but a normal physiological response of the body to a lack of light. In most cases, this is a natural adaptive process that does not require medical intervention.
To help the body restore its normal rhythm, Molostova recommends following certain rules: go to bed and wake up at the same time, engage in physical activity, avoid using phones two hours before sleep, and create dim lighting in the room before bedtime. The body may need several days to adapt. If sleep problems cannot be resolved independently, it is advisable to consult a sleep specialist.
