José Abellán, cardiologist, on sleep: "A good night's sleep regulates your blood pressure, heart rate, and hormones."

Cardiologist José Abellán emphasizes the importance of sleep as an essential pillar for cardiovascular health. Adequate sleep regulates blood pressure , heart rate , and hormones —key functions that, if disrupted, can increase the risk of heart problems. In this context, Abellán warns about the silent effects of poor sleep , which affects millions of people without many being aware of its seriousness.

According to recent data from the Spanish Sleep Society, less than 50% of Spaniards sleep the recommended number of hours. It is estimated that around 4 million people suffer from a sleep disorder, such as insomnia or fragmented sleep . Although the problem is common, it remains underestimated. Abellán insists that poor sleep is not just a temporary nuisance , but a potential trigger for more serious illnesses, especially cardiac ones.

The specialist offers simple tips for improving rest, based on his clinical experience. One of the most interesting recommendations is to avoid lying down during the day if you're not going to sleep, as this habit can disrupt the body's natural rhythms . Abellán points out that the most common mistake is focusing only on the nighttime to try to improve sleep, when in reality what happens during the day significantly influences the quality of nighttime rest.

With a well-established medical career and a growing outreach activity, Abellán argues that good sleep is not a luxury , but a physiological necessity. His critical view of a society marked by immediacy invites reflection: rest is not wasted time , but an investment in health . Therefore, in the event of any sleep disturbance, he encourages people to consult with professionals , avoiding resignation in the face of a problem that does have effective solutions.
