Specialist Reveals the Impact of Hormones on Sleep Quality
Dr. Ilya Barsukov, an endocrinology specialist, confirmed that hormones play a fundamental role in sleep quality. Some hormones help the body relax and fall asleep, while others may cause insomnia and difficulty sleeping.
The expert explained that melatonin is one of the main hormones responsible for regulating sleep. In contrast, elevated levels of thyroid hormones or stress hormones such as cortisol, adrenaline, and noradrenaline keep the body in a constant state of alertness, negatively affecting nighttime rest.
Barsukov pointed out that the effect of hormones on sleep cannot be reduced to a single factor, as it is connected to multiple bodily functions. Some hormones directly influence the sleep cycle, while others regulate alertness, metabolism, and the ability to maintain a balanced sleep routine.
He added that melatonin production requires suitable conditions, particularly sleeping in darkness and avoiding stimulants such as coffee and caffeinated drinks, as well as refraining from eating immediately before bedtime.
The specialist also stressed the importance of limiting the use of electronic devices, especially for children, during the two to three hours before sleep, in addition to ventilating the bedroom and creating a comfortable environment that promotes relaxation.
The doctor noted that sleep disorders may also be linked to thyroid problems. An overactive thyroid accelerates metabolism and increases stress and nervousness, making it difficult to fall asleep. On the other hand, an underactive thyroid can cause excessive daytime drowsiness, which in turn disrupts nighttime sleep.
He further explained that stress hormones are among the main factors that interfere with natural sleep. Therefore, during the evening, the body needs to gradually reduce nervous system activity by avoiding stress sources and disturbing stimuli.
He concluded by emphasizing the importance of maintaining healthy sleep habits, such as going to bed and waking up at regular times, and creating a calm and comfortable bedroom environment to prevent elevated cortisol levels and maintain balanced, healthy sleep.
