Evening workouts linked to 61% lower mortality risk

In the pursuit of optimal health, the timing of physical activity may be more crucial than previously thought, suggests a recent study published in Diabetes Care. Contrary to conventional wisdom, which advocates any exercise at any time, researchers now propose that evening workouts could offer substantial advantages, especially for individuals grappling with obesity and related health issues.

Conducted by scientists from the University of Sydney and other institutions, the study scrutinized data from approximately 30,000 participants enrolled in the UK Biobank study. Focusing on those with a body mass index (BMI) exceeding 30 – indicative of obesity – the researchers sought to unravel the impact of timing moderate-to-vigorous physical activity on health outcomes over an extensive eight-year period.

Participants were segmented into four groups based on their typical exercise time slots: those with negligible activity, morning exercisers (6 a.m. to noon), afternoon athletes (noon to 6 p.m.), and evening exercisers (6 p.m. to midnight). Over the duration of the study, researchers meticulously tracked instances of death from any cause, as well as the emergence of cardiovascular disease and microvascular disease. The results unveiled a notable trend: individuals engaging in evening exercise exhibited the most favorable outcomes.

Compared to their sedentary counterparts, evening exercisers demonstrated a remarkable 61% reduction in the risk of all-cause mortality, along with substantial decreases in the likelihood of cardiovascular and microvascular diseases. While morning and afternoon exercise also conveyed health benefits, the protective effects were not as pronounced as those observed with evening activity. Morning exercisers showcased a 33% lower risk of all-cause mortality, while afternoon exercisers exhibited a 40% reduction, both significantly lower than the 61% observed in evening movers.

These findings held particular significance for individuals with Type 2 diabetes, a population known to grapple with metabolic irregularities. Evening exercise appeared even more advantageous for this group, underscoring its potential in mitigating the detrimental effects of chronic conditions. Scientists speculate on several mechanisms underlying the enhanced efficacy of evening exercise.

Firstly, our bodies exhibit improved blood sugar management later in the day, potentially amplifying the benefits of physical activity during this period. Moreover, evening exercise may facilitate the clearance of excess glucose from the bloodstream, particularly crucial for individuals with diabetes prone to elevated blood sugar levels.

The study’s lead researcher, Dr. Ahmadi, a National Heart Foundation postdoctoral research fellow at the University of Sydney’s Charles Perkins Centre, emphasized the inclusive nature of the study’s findings. Regardless of the activity type – be it structured exercise or mundane tasks like household chores – any form of movement stands to benefit health.

However, researchers caution against fixating solely on exercise timing, stressing the paramount importance of consistency in physical activity routines. Nonetheless, for those with the flexibility to adapt, incorporating an evening stroll or workout session may yield substantial dividends in safeguarding health and longevity.

In light of these findings, the timing of physical activity warrants further exploration in the realm of obesity and diabetes management. As research continues to unfold, it’s becoming increasingly apparent that the optimal “exercise prescription” may extend beyond the realm of mere quantity to encompass strategic timing.
