Alcohol abuse vastly disrupts circadian rhythms, which can lead to increased alcohol dependence and relapse in abstinent alcoholics. In mammals, circadian timing is regulated by influencers like diet, social interactions, and exercise. A new study looking into the connection between alcohol consumption and wheel-running in hamsters suggests that exercise may prove an effective alternative to bring down alcohol intake in humans. Alcohol abuse is identifiable by routine craving for and consumption of alcohol in order to function normally. This behavior interferes with both the timing and consolidation of daily circadian rhythms - rendering the individual unsure of when to sleep, eat, and mate. Extended alcohol abuse leads to skewed dietary regime, sleep routine as also depleted physical and mental health. Scientists conducting the study observed that alcohol craving in alcohol-naïve hamsters prompted to engage in more wheel-running activity evidenced less alcohol consumption. The results hold out the promise that it may be possible to reduce addiction to alcohol and drugs in humans in future with the help of exercise.
