Scientists at the University of Liverpool have found that high levels of a stress hormone in recovering alcoholics could increase the risk of relapse. The study showed that cortisol, a hormone produced by the adrenal gland in response to stress, is found in high levels in chronic alcoholics, as well as those recovering from the condition. Researchers found that this could result in impaired memory, attention and decision-making functions, which could decrease the patient's ability to engage with treatment.
A review of research studies indicate that alcohol consumption can increase the risk for developing atrial fibrillation. Atrial Fibrillation (AF) is the most common cardiac arrhythmia (abnormal heart rhythm). Its name comes from the fibrillating (i.e., quivering) of the heart muscles of the atria, instead of a coordinated contraction.
Research indicates that individuals who have a high frequency of energy drink consumption (52 or more times within a year) were at a statistically significant higher risk for alcohol dependence and episodes of heavy drinking.
