People who snore heavily are likely to burn more calories than those who snore lightly, even if they are awake, London’s Daily Mail reported.

Researchers from the University of California, San Francisco, discovered people with serious snoring problems burned around 2,000 calories a day, compared to people who snored lightly.

However, snoring is still not a healthy habit — it can be the result of an underlying health problem, such as obesity or sleep apnea.

Snoring might be linked to energy metabolism, which could explain why some sufferers gain weight easily.

Scientists studied 212 patients, all of whom snored or had sleeping-related conditions, such as sleep apnea.

“Obesity is a major risk factor for the development of sleep-disordered breathing and changes in body weigh are associated with changes in sleep-disordered breathing severity,” the researchers wrote in the journal Archives of Otolaryngology — Head & Neck Surgery.

It was determined that the energy given off while the body is asleep and resting may be affected by improved reactions in the body’s nervous system caused by snoring and/or snoring-related problems.

'It is unclear whether weight gain is simply a cause of sleep-disordered breathing or whether sleep-disordered breathing may be associated with alterations in energy metabolism that, in turn, lead to weight gain and complicate the treatment of these two disorders that often coexist,” the authors wrote.
