Chapter 1: The Effects of Alcohol on the Body

When people drink, the common response is simply, “I get drunk, duh!” However, there's a lot more happening inside your body when you consume alcohol.

While I may not be a medical expert, I am an educator, and one of the best ways to grasp new concepts is through summarization. This method strengthens neural connections in the brain.

But what really occurs internally when you indulge in a drink? Let's take a journey through a typical evening to uncover the effects of alcohol.

Wine O’Clock: The Evening Begins

As you arrive home, the chaos from the car ride with your kids has you feeling frazzled. After unloading the groceries and shedding your coat, you swiftly reach for your wine glass to pour a generous serving while you prepare dinner.

With your first few sips, you may notice a wave of relaxation wash over you. This response occurs because ethanol, the active ingredient in alcohol, acts as a depressant on your central nervous system, beginning with your brain's prefrontal cortex—the area responsible for decision-making.

So why does alcohol hit your brain before affecting the rest of your body? Unlike food, which is digested gradually, alcohol quickly enters your bloodstream, impacting every cell in your body, both water and fat-soluble.

Moreover, your brain releases dopamine, a neurotransmitter linked to feelings of pleasure, which might lead you to hum happily as you mix the salad.

After your brain, alcohol then influences other organs such as your kidneys, lungs, and liver. Notably, if you weigh less or have not eaten recently, you will feel the effects of alcohol more intensely due to less tissue available to absorb it.

Mommy's Buzz: A Rising Temperature

As you pour another glass to accompany dinner, you might wonder why it suddenly feels hot. This sensation arises as your liver metabolizes the alcohol, generating heat and causing your blood vessels to expand, which surprisingly cools your internal body temperature.

Just One More: The Cycle of Consumption

Alcohol is classified as a depressant, which means it slows down your brain and spinal cord functions. Your brain is constantly striving for balance and becomes sensitive to your alcohol intake, reacting by producing stimulants and hormones to counteract the depressant effects.

As the depressant effects begin to wear off, the stimulants linger, which can leave you feeling hyper or anxious. Have you ever finished a drink and felt an urge for another? Once the dishes are done, you might find yourself settling in with yet another glass.

This pattern becomes habitual: drink a depressant, generate stimulants, and repeat. This cycle can continue until you either pass out or choose to stop.

As you consume more alcohol, levels of adenosine—a chemical that induces fatigue—accumulate in your body. In addition, your brain releases cortisol, the stress hormone, which ironically increases your stress levels despite the perception that alcohol is a stress reliever.

The Downward Spiral

Despite the initial sense of relaxation, alcohol disrupts your body's natural stress management systems, leading to a cycle of increased consumption. Eventually, your body can no longer process the alcohol efficiently, leading to a shutdown of your system.

Instead of falling into a restful sleep, you may find yourself in a state of unconsciousness, as your body reallocates energy to process the alcohol. This leaves you feeling unrested, as the stimulants make your brain feel as if it’s had too much caffeine, combined with the constant need to relieve your bladder due to alcohol’s diuretic properties.

In Conclusion

Drinking alcohol triggers a complex series of reactions in your body. Understanding these effects can inspire you to reconsider your habits and their long-term implications on your life and health.
