Chronic insomnia, which affects approximately 10% of the world’s population, is much more than just difficulty sleeping. In addition to having an immediate impact on sleep quality and general well-being, it has also been associated with a number of long-term health problems, such as metabolic disorders (obesity, diabetes) and mental disorders (anxiety, depression). This connection between insomnia and various health conditions highlights the urgent need to better understand this problem and develop effective interventions.
According to a recent study, in which the Polytechnic University of Madrid (UPM) in Spain participated, this sleep disorder is closely linked to an increased risk of suffering from cardiovascular diseases due to the increased activity of the sympathetic nervous system during sleep . dream This finding suggests the importance of rethinking insomnia treatment strategies by including more comprehensive and preventative interventions.
The research team, which also included specialists from the Complutense University of Madrid (UCM), the La Princesa University Hospital of Madrid and the companies Brainguard and Eesy-Innovation, all Spanish entities, analyzed the sleep of patients suffering from chronic insomnia , comparing the results with those of a group of people without sleep problems. The results were revealing: they found a marked difference in sympathetic nervous system activity between the two groups, being significantly higher in people who suffered from insomnia. This excessive nervous activity manifests itself through an increase in skin temperature and increased sweating, factors that could explain the link between insomnia and the risk of developing cardiovascular problems.
This study represents an important step in understanding chronic insomnia and its health implications. The findings highlight the importance of addressing insomnia not only as a sleep disorder, but also as a risk factor for cardiovascular problems. “This knowledge can have a significant impact on public health, highlighting the need for greater awareness and medical attention towards the treatment of insomnia,” says Rybel Ramos, co-author of the study and a doctor at the Hospital de La Princesa.
The study used a wearable device to measure physiological signals of sweating, temperature, accelerometry and photoplethysmography during sleep. The study involved 51 patients who slept overnight in the Sleep Unit of La Princesa Hospital.
The findings suggest that patients with insomnia have greater sympathetic activity during sleep, especially during REM sleep, and less pronounced during the deepest phase of sleep. These differences could explain the increased risk of cardiovascular disorders in patients with insomnia. Furthermore, these results show how wearable devices are emerging as a useful tool in the outpatient setting to detect patients with insomnia and/or increased risk of cardiovascular disorders, as supported by Marta Verona, co-author of the work and researcher at UPM and Eesy- Innovation.

The results of this study highlight the importance of rethinking insomnia treatment strategies. In addition to improving the quality of sleep, it is essential to recognize insomnia as a risk factor for chronic diseases, such as cardiovascular diseases. This new perspective opens the door to more comprehensive and preventative interventions, improving both patients’ quality of life in the short term and their overall health in the long term.
