In Italy, one in four individuals experiences sleep disorders, and between 10% and 15% suffer from chronic insomnia; nonetheless, the issue is frequently underestimated or addressed only superficially. Nevertheless, sleep deprivation impacts the nervous system, diminishes immune function, undermines metabolic and cardiovascular health, and deteriorates mood, concentration, and social interactions. It is essential to recognize that, as Claudio Mencacci, psychiatrist and co-president of the Italian Society of Neuropsychopharmacology, emphasizes, "there exists a bidirectional relationship between sleep and kindness: individuals who experience inadequate sleep tend to be more irritable, less empathetic, and more susceptible to conflict. Conversely, quality sleep supports emotional regulation, and harmonious relationships, in turn, enhance sleep quality". From Michelangelo (Night) to Goya (The Sleep of Reason Produces Monsters), from Munch (Sleepless Night) to Dalí (Sleep), up to contemporary works by Wall (Insomnia) and Bourgeois (Insomnia Drawings), great artists of every era have depicted insomnia as a condition that affects mental and emotional balance. Today, evidence affirms that excellent sleep is beneficial to health, prevention, and social cohesion, and it encourages us to recognize and address insomnia without discounting it. These were the primary themes of the press conference "Hypnosis - Shedding Light on the Night", which took place in Milan. The event showcased a journey through fifteen artworks dedicated to the theme of insomnia, described by Sergio Risaliti, Artistic Director of the Museo Novecento in Florence, as a dialogue between art and science aimed at refocusing attention on the importance of sleep as an "invisible cure". "Sleep is a fundamental necessity and a potent preventive measure: it safeguards the cardiovascular system, facilitates tissue regeneration, and clears waste from the brain, thereby reducing the risk of neurodegenerative diseases", explains Carolina Lombardi, Director of the Sleep Medicine Center at the Auxologico Italiano IRCCS Institute in Milan. Scientific evidence suggests that a lack of rest raises the risk of psychological, metabolic, and cardiovascular diseases. Among young individuals, the co-occurrence of multiple insomnia symptoms is correlated with an elevated risk of developing hypertension in later adulthood. It's no coincidence that sleep is one of the American Heart Association's eight foundations of cardiovascular health.
