A recent study conducted by researchers at the University of California, Los Angeles (UCLA) has found a strong link between sleep deprivation and an increased risk of obesity. The study, which was published in the journal Sleep, analyzed data from nearly 3,000 adults and found that those who slept less than six hours per night were significantly more likely to be obese than those who slept seven to nine hours per night.
The study also found that the risk of obesity increased as the amount of sleep decreased. For example, participants who slept less than six hours per night were 73% more likely to be obese than those who slept seven to nine hours per night. Similarly, those who slept less than five hours per night were almost twice as likely to be obese as those who slept seven to nine hours per night.
The researchers say that the link between sleep deprivation and obesity may be due to changes in the hormones that regulate hunger and metabolism. When we don’t get enough sleep, our bodies produce more of the hormone ghrelin, which stimulates appetite, and less of the hormone leptin, which suppresses appetite. This can lead to overeating and weight gain.
The study also found that sleep deprivation was more strongly associated with obesity in women than in men. The researchers say this may be due to the fact that women are more likely to have sleep disorders such as insomnia, which can disrupt their sleep patterns and lead to weight gain.
The findings of this study underscore the importance of getting enough sleep for maintaining a healthy weight. While many people struggle to get the recommended 7-9 hours of sleep per night, it is important to make sleep a priority. This can include establishing a regular sleep schedule, avoiding screens before bed, and creating a comfortable sleep environment.
“This study adds to the growing body of evidence that suggests sleep plays a critical role in maintaining a healthy weight,” said lead author Dr. Andrew Calvin of UCLA. “It highlights the importance of getting enough sleep to not only help prevent obesity, but also to improve overall health and well-being.”
This study is a reminder that while diet and exercise are important in weight loss and management, it’s also important to pay attention to the amount and quality of sleep we get, as it plays a crucial role in maintaining a healthy weight and overall well-being.
