There are, I'd venture to say, two types of people in the mornings: those who snooze through alarms, and those who don't. And it's probably fair to say that society is a bit rough on snoozers. They are often characterised as lazy and undisciplined - bad sleep hygiene, if you will. But is that UNFAIR? Could hitting the snooze button on your alarm clock in fact be beneficial? A new study published in the Journal of Sleep Research suggests just that - the study's lead author is Tina Sundelin, a sleep researcher from Stockholm University.
