When you learn about how alcohol affects your body, it can be quite surprising. Once you drink alcohol, about 20% of it is absorbed directly into your stomach, which means it enters your bloodstream quickly. This rapid absorption is similar to the effect of a needle injecting a substance directly into your stomach.
Once alcohol reaches your brain, it interacts with certain chemicals called neurotransmitters. One of these is glutamate, an excitatory neurotransmitter that usually helps stimulate brain activity. While this might sound like it could be exciting, alcohol actually suppresses these excitatory neurons, leading to a slowdown in brain function.
It’s interesting to compare alcohol to other substances. Many substances have more pronounced excitatory effects, which can make them feel more stimulating. If you’ve ever smelled pure alcohol, you know it has a strong, intense odor. This is your body’s way of warning you about its potency. While people often try alcohol out of curiosity, it’s crucial to understand that not all substances affect the body in the same way.
Consider the difference between alcohol and something like lemons. Lemons have a refreshing smell and are beneficial to your health. They don’t cause any disorders, unlike alcohol. In fact, a lack of vitamin C, which lemons are rich in, can lead to a condition called scurvy. This highlights how natural substances can have positive effects, unlike the potential negative impacts of alcohol.
Understanding the effects of alcohol on your body and brain is important. While it might be tempting to experiment with alcohol, being aware of its potential impacts can help you make informed decisions. Remember, not all substances are created equal, and some, like lemons, can be both pleasant and beneficial to your health.
Design a diagram that illustrates how alcohol is absorbed into the body and its effects on the brain. Use arrows and labels to show the path alcohol takes from ingestion to its impact on neurotransmitters. This will help you visualize and better understand the process.
Engage in a classroom debate where you take on roles of different substances, including alcohol and natural substances like lemons. Argue the effects and benefits or drawbacks of each, using evidence from the article to support your position.
Research another substance that affects the body and brain differently from alcohol. Prepare a short presentation comparing its effects to those of alcohol, highlighting any surprising findings.
Conduct an experiment where you compare the smell of alcohol with other natural substances like lemons. Record your observations and discuss how these smells might indicate the effects of the substances on the body.
Write a reflective essay on the potential impacts of alcohol on your health and decision-making. Include insights from the article and personal reflections on how this information might influence your choices.

Whenever you learn about alcohol biophysiologically, it can be quite alarming. When you drink it, about 20% is absorbed in your stomach, so it gets into your system pretty quickly. It’s somewhat similar to a needle in the stomach. When alcohol reaches your brain, it affects the excitatory neuron glutamate, which sounds like it could be fun and good. However, it also impacts the inhibitory neurons. In this case, alcohol significantly suppresses the excitatory neurons.
It’s interesting to note that with other substances, the excitatory effects are often more pronounced. Additionally, if you’ve ever smelled pure alcohol, it can be quite intense. Your body instinctively reacts to it, and while people often experiment with alcohol, it’s important to recognize that not all substances have the same effects. For example, lemons have a pleasant smell and don’t lead to any disorders, unlike alcohol. In fact, the opposite condition related to a lack of vitamin C is called scurvy.

Alcohol – A chemical substance that can alter the mind and body, often found in beverages like beer, wine, and spirits, and can affect the central nervous system. – Excessive consumption of alcohol can lead to liver damage and impair cognitive functions.
Brain – The organ in the body that serves as the center of the nervous system, responsible for processing sensory information and controlling bodily functions. – The human brain is capable of forming new neural connections throughout life, a process known as neuroplasticity.
Neurotransmitters – Chemical messengers that transmit signals across synapses from one neuron to another in the nervous system. – Dopamine is a neurotransmitter that plays a significant role in reward and motivation pathways in the brain.
Glutamate – An amino acid that functions as a major excitatory neurotransmitter in the brain, involved in cognitive functions like learning and memory. – An imbalance of glutamate levels in the brain can contribute to neurological disorders such as epilepsy.
Absorption – The process by which substances are taken up into the body, often referring to the uptake of nutrients or drugs into the bloodstream. – The absorption of nutrients in the small intestine is crucial for maintaining overall health and energy levels.
Substances – Materials with distinct properties, often referring to chemicals or compounds that can affect biological systems. – Certain substances, like nicotine, can have addictive properties and impact brain chemistry.
Health – The state of complete physical, mental, and social well-being, not merely the absence of disease or infirmity. – Regular exercise and a balanced diet are essential for maintaining good health and preventing chronic diseases.
Vitamin – Organic compounds that are essential in small quantities for normal growth and nutrition, usually obtained through diet. – Vitamin D is important for bone health as it helps the body absorb calcium effectively.
Scurvy – A disease resulting from a deficiency of vitamin C, characterized by symptoms like anemia, gum disease, and skin problems. – Scurvy was historically common among sailors who lacked access to fresh fruits and vegetables during long sea voyages.
Effects – Changes that occur as a result of a particular action or influence, often used to describe the impact of substances on biological systems. – The effects of prolonged stress can include increased risk of cardiovascular diseases and weakened immune response.
