RESEARCH: Newly discovered gene governs need for slumber when sick

RESEARCH : Animal health = human health.RESEARCH: Newly discovered gene governs need for slumber when sick. Humans spend nearly one-third of their lives in slumber, yet sleep is still one of biology's most enduring mysteries. Little is known about what genetic or molecular forces drive the need to sleep -- until now. In a study of over 12,000 lines of fruit flies, researchers have found a single gene, called nemuri, that increases the need for sleep. The NEMURI protein fights germs with its inherent antimicrobial activity and it is secreted by cells in the brain to drive prolonged, deep sleep after an infection.

Why Do Cats Sleep So Much?.

Why Do Cats Sleep So Much?. How much do cats sleep? Cats sleep between 15 and 20 hours a day! This is twice as much sleep as most other mammals need.

 Cats get that much sleep by taking naps throughout the day and night, rather than sleeping for 18 hours all at once. Cats are crepuscular, this means that they are the most active during twilight times (dusk and dawn). During most other times of the day, they are either snoozing or in a deep sleep. 

Snoozing refers to the type of sleep when cats are usually sitting upright with their eyes partly open, and their ears twitch in response to noises. Cats are in a half-asleep state when they are snoozing, and about 75% of a cat's sleep-time is this type of sleep.

During deep sleep, cats are usually curled up, eyes completely closed, and they sometimes have their faces covered by their paws or tail. The well-known term "catnap" pays homage to these extraordinary feline sleeping abilities and styles.

LINK BETWEEN PETS ,GOODNIGHT REST AND HEALTH OF PET OWNER.

According to a Mayo Clinic study surveying 150 people, "more respondents perceived their pets to not affect or even benefit rather than hinder their sleep," while "some respondents described feeling secure, content and relaxed when their pet slept nearby." In their research, Krahn's team used interviews and questionnaires to discover how pets in the bedroom affect sleep. Seventy-four of the 150 adults interviewed had at least one pet, and 31 had multiple pets. More than half (56 percent) of pet owners allowed their animal (or animals) to sleep with them in the bedroom or on the bed.Only 15 pet owners (20 percent) considered the pet's presence "disruptive" to their sleep. Some said their pets wandered, snored, whimpered or needed bathroom breaks, for example. One single 51-year-old woman complained that her pet parrot "consistently squawked at 6 a.m.," according to the researchers."A single 64-year-old woman commented that she felt more content when her small dog slept under the covers near her feet," Krahn's group wrote. In addition, they reported that a 50-year-old woman said she did "'not mind when my lovely cat' slept on her chest and another described her cat as 'soothing.'" Some people even said that part of the reason they acquired a dog or cat in the first place was to help them relax at night, and this was especially true for single people or people whose partners often traveled or worked at night.The researchers stressed that having a pet in the bedroom is not always a calming experience, and people should prioritize their need for restful sleep over the need of a pet to be close by. story credit; Health day.
