Adults who take longer than 30 minutes to fall asleep have more than twice the risk of death than adults who take less than 30 minutes to fall asleep.
It's okay. That doesn't mean that the next time you have insomnia, you will die sooner. It just means that they have seen a relationship between poor sleep and an increased risk of death. So perhaps people who have more medical problems can't sleep as well. Or perhaps people who don't sleep well develop more medical problems that increase their risk of death.
