Daily cold exposure with shivering for 10 days improves glucose tolerance and metabolic health in individuals with obesity, highlighting shivering's role.
By Priyanjana Pramanik, MSc.Reviewed by Lily Ramsey, LLMDec 10 2024 One hour of daily cold exposure with shivering for 10 days enhances glucose tolerance and metabolic health in individuals with overweight or obesity.In a recent study published in Nature Metabolism , researchers investigated the effects of shivering due to cold on metabolic health in people with obesity and overweight.
The study participants were White individuals of Western European descent, including four post-menopausal women. They ranged in age from 40 to 75 years and had a body mass index between 27 and 35. The study also assessed changes in skeletal muscle gene expression through RNA sequencing and examined markers related to glucose transport and glycogen concentration. To assess cardiovascular effects, blood pressure was measured before and after the intervention.
Cold acclimation also had positive effects on lipid metabolism, including a 14% reduction in the NEFA AUC and a 32% reduction in fasting triglycerides. This suggests that cold exposure with shivering can improve glucose and lipid homeostasis.
