Alcohol can have immediate physical effects on many parts of your body. You may notice some of these effects while others can go unnoticed.
Central Nervous System
The central nervous system (CNS) refers to your brain and spinal cord. The effects of alcohol on the CNS are some of the most apparent as the people around you may notice them too. CNS effects can include impaired coordination, reaction times, and balance. Alcohol can also affect speech.
The reason for this is alcohol is a depressant, meaning it slows down bodily functions, including brain activity. When you become impaired from alcohol, you may experience the above effects as a result of the alcohol slowing down your brain’s communication.
Gastrointestinal System
The gastrointestinal system includes your mouth, throat, esophagus, stomach, intestines, rectum, anus, liver, gallbladder, and pancreas. Many people are familiar with the effects of alcohol on the gastrointestinal system as they include nausea, vomiting, heartburn, gastritis, and even ulcers with repeated use. Alcohol causes inflammation in the gastrointestinal system and interferes with its regular processes by impacting stomach acid production, causing the above effects.
Cardiovascular System
The less frequently discussed effects of alcohol are those on the cardiovascular system, your heart, and blood vessels. Alcohol can increase levels of cortisol, affect your heart rate, and cause high blood pressure. In large amounts, this can lead to issues such as stroke.
General Well-Being
Alcohol can also have immediate effects on your general well-being including your immune health and sleep hygiene. Simply put, alcohol weakens your immune system and can make you more susceptible to infections for up to 24 hours.
In a similar vein, alcohol is notorious for causing sleep disruptions, which can exacerbate a weakened immune system. Many people experience a decrease in the quality of their sleep when they drink alcohol. Additionally, it can negatively impact your sleep cycles, specifically rapid eye movement (REM) sleep – the deepest phase of sleep.
