Intermittent cold exposure has garnered increased attention in popular culture, largely for its proposed effects on mood and immune function, but there are also suggestions that the energy wasting mechanisms associated with thermogenesis may decrease body weight fat mass. Considering continued worsening prevalence of obesity type II diabetes, any protocol can reduce and/or improve metabolic health would be a substantial boon. Here, we present narrative review exploring research related to ICE adipose tissue. Any publicly available original examining repeated bouts outcomes was included. While does not consistently lower bodyweight or mass, seem evidence as positive modulator consequences obesity, such glucose tolerance insulin signaling.

Abstract Background Cardiovascular disease (CVD) is closely associated with Insulin Resistance (IR). However, there limited research on the relationship between trajectories of IR and CVD incidence, considering both time-invariant time-varying confounders. We employed advanced causal inference methods to evaluate longitudinal impact risk. Methods The data for this study were extracted from a Chinese nationwide cohort, named China Health Retirement Longitudinal Study (CHARLS). Triglyceride-glucose (TyG) index TyG body mass (BMI) used as surrogate markers IR, their changes recorded exposures. targeted maximum likelihood estimation (LTMLE) was how dynamic shifts in (i.e., increase, decrease, etc.) influence long-term risk, adjusting Results A total 3,966 participants included analysis, 2,152 (54.3%) being female. average age at baseline 58.28 years. Over course 7-year follow-up period, 499 (12.6%) developed CVD. Four distinct TyG-BMI identified: low stable, increasing, decreasing, high stable. LTMLE analyses revealed individuals ‘high stable’ ‘increasing’ groups had significantly higher risk developing compared those ‘low group, while ‘decreasing’ group showed no significant differences. Specifically, when exposure set TyG-BMI, odds 1.694 (95% CI: 1.361–2.108) times than group.

The divided into four groups according quartiles TyG index: ln ([triglyceride × fasting glucose]/2), AIP calculated as log (triglyceride/high-density lipoprotein cholesterol), (ln ([2 glucose] + triglyceride) body mass index)/(ln [high-density cholesterol–cholesterol]). We prospectively assessed hazard ratios (HRs) with 95% confidence intervals (CIs) using multivariate Cox proportional regression models after adjusting potential confounding variables.
