With the festive season over, many people are considering Dry January as a New Year's resolution. Dr Babak Ashrafi, a doctor at Superdrug Online Doctor, has outlined ten health benefits that participants may experience from abstaining from alcohol for the month.
Firstly, sobriety can reduce hepatic fat and lower inflammation, normalising liver enzymes such as ALT and GGT. This improves the liver's ability to regulate metabolism and remove toxins. Even a short break can reverse early-stage fatty liver changes, reducing the risk of long-term liver disease.
Alcohol raises blood pressure by stimulating the nervous system and increasing cortisol. Removing alcohol can lead to meaningful reductions in both systolic and diastolic blood pressure, improving vascular relaxation and reducing arterial stiffness. Additionally, going sober helps rebalance fat transport, lowering total cholesterol and triglycerides, which supports heart health.
Alcohol disrupts glucose regulation, but removing it improves insulin sensitivity and stabilises blood sugar levels. This is particularly beneficial for those with insulin resistance or type 2 diabetes. Many also experience modest weight loss, especially reductions in visceral fat, due to the removal of excess calories.
Although alcohol can induce drowsiness, it disrupts sleep architecture, reducing REM sleep. Cutting it out restores healthier sleep cycles, leading to deeper, more restorative sleep, which enhances energy, concentration, and mood. Furthermore, alcohol suppresses immune cell activity; abstaining allows immune regulation to normalise, improving the body's ability to fight infections.
Finally, while alcohol may temporarily boost mood, it is a depressant that disrupts serotonin and dopamine. Abstinence stabilises these neurotransmitters, reducing anxiety and improving emotional regulation. Dr Ashrafi notes that some individuals may experience short-term discomfort, but the long-term benefits are significant.
