The researchers found that when glucose was restored, subjects' self-control behaviours - such as controlling attention, regulating emotions, quitting smoking, coping with stress, resisting impulsivity, and refraining from criminal and aggressive behaviour - was improved. Then, ever wondered why you lose self-control after a couple of drinks? It's because alcohol reduces glucose throughout the brain and body, thereby impairing self-control. The glucose-self-control theory could also explain why many ex-smokers turn to sweets when they quit. 0 More: Daily Dose: This is why your vanilla or cinnamon flavoured e-cigarette is toxicHealth-in-Motion advertisement Other news News KZN Health Department breaks world record for Pap smears Parenting This is why your kids are sleeping less these days Diet and nutrition Should you really start eating more saturated fat?
