Sleep could be the key to save endangered Quolls

According to a new Australian study, endangered male northern quolls are giving up sleep for more sex - and it could be killing them. While studying quoll travel patterns, researchers found that males travel long distances searching for mating partners, giving up sleep in the process. They also found that male quolls attract more parasites, most likely because they devote less time to grooming so they can make the most of each breeding season. A lack of sleep might be the reason why the male marsupials typically mate themselves to death in one breeding season while females live and reproduce for up to four years, experts say.

Sleeping Pills associated with higher risk for dementia

A new study published in the Journal of Alzheimer’s Disease suggests that older adults who take sleeping pills may have an increased risk of developing Alzheimer’s disease. Researchers found that older adults who said they “often” or “almost always” took sleep aids had a 79% higher chance of developing dementia compared to those who “never” or “rarely” used them. They also found that this connection only existed in white study participants. Further studies are needed to determine if the sleep medications themselves are harmful or if it’s the frequent use of sleep medications that links to an increased dementia risk.

Paul Rudd finally revealed his secret to getting in shape for his superhero role: Sleep! That’s right, when Men’s Health asked Rudd what routine he uses to get in super shape and the actor simply attributed it to his sleep schedule. Of course, Rudd says he also runs and tries to lift weights three times a week but, "the most important part of training is sleep," he told Men’s Health. "People will set their alarm and then sleep for four hours and they’ll get up so that they can train. They’re doing themselves a disservice."
