Inserito da

A good night’s sleep the key to being attractive. If you want to look attractive and healthy, the best thing you can do is get a good night’s sleep, finds researchers at Karolinska Institutet in a novel study published in BMJ online. For the first time, say the authors, there is scientific backing for the concept of beauty sleep. If you want to look attractive and healthy, the best thing you can do is get a good night’s sleep, finds researchers at Karolinska Institutet in a novel study published in BMJ online. For the first time, say the authors, there is scientific backing for the concept of beauty sleep. The study, led by

Associate Professor John Axelsson at the Department of Clinical Neuroscience, investigated the relationship between sleep and perceptions of attractiveness and health. Twenty-three participants between the ages of 18 to 31 took part in the study. They were photographed between 2 pm and 3 pm on two occasions, once after normal sleep and once after being deprived of sleep. Smokers were excluded from the research and no alcohol was allowed for two days prior to the experiment. The photographs were taken in a well-lit room and the distance to the camera was fixed. During both photography sessions participants wore no make-up, had their hair loose (combed back if they had long hair) and underwent similar cleaning or shaving procedures. They were asked to have a relaxed, neutral facial expression for both photos.Sixty-five observers rated the photographs for attractiveness and whether the individuals looked healthy/unhealthy or tired/not tired. The observers judged the faces of sleep-deprived participants as

less healthy, less attractive and more tired. The researchers conclude that the facial signals of sleep deprived people affect facial appearance and judgments of attractiveness, health and tiredness.  –  Sleep, cognition and health; “The main purpose with our research is to increase the understanding and awareness of how our physiological- and cognitive processes reacts (and adapts) to periods with disturbed sleep and inflammation.” Our research;  We are  studying the physiological (neuroendocrine, immune, metabolic) and behavioural (health perception, sleepiness, cognitive performance) consequences of sleep loss with relevance for public health and safety. A main aim is to investigate how physiological and behavioural processes adapt to remain homeostasis during the challenges of disturbed sleep and inflammation. The purpose is to increase the understanding and awareness of the adaptive and maladaptive values of these changes. Current projects; * Brain activity, perceived health and pain regulation during inflammation * Effects of chronic sleep restriction on metabolism and immune function  * Effects of sleep loss and inflammation on health perception * Individual differences in tolerance to sleep loss * Is there something called “Beauty sleep”? * Influences of sleep loss and subjective variables on judged health.  Professor John Axelsson, group leader.
