A month without alcohol: scientists explain how the liver and sleep will change

Giving up alcohol for 30 days can improve sleep, digestion, normalize blood pressure and metabolism. The liver gets a chance to recover, but the degree of improvement depends on the initial state of the organ. A 2018 study showed favorable changes in blood pressure, body weight, and insulin sensitivity in participants who consumed alcohol in moderately large amounts.

Giving up alcohol for 30 days can positively affect the body's condition. During this time, some people experience improved sleep quality and digestion, reduced blood pressure, and the liver gets a chance to recover after regular alcohol exposure. Additionally, abstinence can help assess one's own habits and understand how important a role alcohol plays in daily life. Contrary to popular belief, quitting alcohol is not always accompanied by an immediate improvement in well-being. If a person regularly consumed alcohol in large quantities, in the first hours and days, withdrawal symptoms may appear: anxiety, irritability, restlessness, and increased sweating. Symptoms may begin about eight hours after the last alcohol consumption and peak within 72 hours. In a 2018 study, scientists found that after a month of abstinence, participants who consumed alcohol in moderately large amounts improved some health indicators: blood pressure, body weight, and insulin sensitivity. Quitting alcohol can also relieve heartburn and improve sleep, especially in those who are used to drinking before bed. After three weeks without alcohol, some people may experience favorable changes in certain inflammatory and immunological markers.
