A new population study from Norway found that insomnia is associated with an increased risk of incident heart failure. The study followed more than 50,000 people for 11 years, noted BBC News. "We still do not know whether heart failure is really caused by insomnia, and it is still unclear why insomnia is linked to higher heart failure risk,” principal investigator Dr. Lars Laugsand told HealthDay.
