The United Kingdom recently banned the sale of cigarettes to people under 18 years. One of the many reasons that it was banned was that it caused lung cancer. Alcohol also causes cancer, and we’ve known that for at least 37 years, since the World Health Organisation (WHO) first published findings in 1987. Yet sales remain strong. What Exactly Is Alcohol? And Why Does It Sell So Much?Alcohol is a chemical compound that typically refers to ethanol, the type found in alcoholic beverages like beer, wine, and spirits. It is produced through the fermentation of sugars by yeast, and when consumed, it acts as a depressant on the central nervous system. This intoxicating effect is the reason it sells so much. What Does Alcohol Do To Your Brain?Primarily, alcohol interferes with the brain's communication pathways. According to the National Institutes of Health (NIH), alcohol can also alter how the brain looks and functions. It disrupts the areas of the brain responsible for balance, memory, speech, and judgment, increasing the likelihood of injuries and other negative outcomes. Long-term alcohol consumption can permanently change neural pathways, leading to lasting cognitive and emotional effects.Moreover, it is a proven fact that alcohol can worsen mood swings. Recent research shows that alcohol may exacerbate symptoms of bipolar disorder by destabilising mood, which impacts efficiency at work. Alcohol also affects conditions like depression and panic disorder, and can trigger impulsive behaviour. Additionally, alcohol has been shown to disrupt sleep patterns, making it harder to get restorative rest.What Does Alcohol Do To Your Heart?Alcohol, particularly heavy drinking, including heart conditions. Excessive alcohol intake can lead to high blood pressure, heart failure or stroke. Excessive drinking can also contribute to cardiomyopathy, a disorder that affects the heart muscle. What’s more, alcohol can contribute to obesity and the long list of health problems that can go along with it. Alcohol is a source of excess calories and a cause of weight gain that can be harmful in the long term. The takeaway is what you probably already knew: If you choose to drink alcohol, stick to moderate levels of drinking, and don’t overdo it.
