Pharmacist Álvaro Fernández on Why Summer Blankets Aid Sleep

In a recent interview, pharmacist Álvaro Fernández explained why many people choose to sleep under a blanket even when temperatures soar above 30 °C. He highlighted that the added covering triggers a modest rise in serotonin production, a hormone known to regulate sleep cycles and mood.

The serotonin boost, according to Fernández, helps the brain transition more smoothly into deep sleep despite the heat. Fernández noted that the sensation of being wrapped also creates a psychological sense of security, reducing nighttime anxiety for many sleepers.

He emphasized that this practice is common among athletes who rely on optimal recovery, as a comfortable sleep environment directly impacts performance. The pharmacist warned that while a blanket can aid sleep, proper ventilation remains essential to avoid overheating.

Overall, Fernández concluded that using a blanket in summer is a scientifically backed strategy to enhance sleep quality and promote overall well‑being.
