Disruptive sleep can make you gain weight, says a new study. According to researchers, a sound sleep is necessary for good health, however, people who sleep in shifts tend to eat more than those who sleep in a single stretch leading to several health=related problems including obesity, type 2 diabetes and heart diseases in future.
Through the research published in the Journal of Health Psychology, researchers Alyssa Lundahl and Timothy D Nelson of the University of Nebraska- Lincoln, USA, explained that several factors are to be blamed for overeating after a poor sleep. Predominantly, the hormones controlling the appetite get affected after a night of disruptive sleep. Thus, people feel hungry and eventually end up eating more. Study authors noted that level of hunger hormone — ghrelin, increased after poor sleep while level of hormone called leptin was significantly reduced. Leptin also called “satiety hormone”, regulates energy balance by inhibiting hunger.
Apart from hormonal imbalance created by disruptive sleep, tired people are prone to emotional stress which leads to comfort eating, also it triggers inability to resist tempting food.
“It is well recognized that food intake is implicated in many chronic health issues including obesity, diabetes and heart disease, and diet is often a target of treatment to prevent the onset of these conditions. Understanding the mechanisms linking disrupted sleep patterns to increased food intake is important for informing both prevention and treatment interventions for chronic health conditions,” said study authors.
On future effects of the improper sleep, researchers warned that its effect is so pronounced and inevitable that doctors treating diseases like obesity and type 2 diabetes should insist on changing person’s bedtime rather than changing their dietary pattern.
Moreover. the research has made it clear that what a person eats and what amount of food a person consumes depends on biological, emotional, cognitive and environmental factors. With life getting faster day by day, a person might not get proper sleep, the problem is more pronounced for people working in shifts. Researchers warned these people to get a sound sleep or suffer severe consequences in the long run.
