How even one glass of beer affects our body and brain and why the effects differ between individuals.
From the moment we take the first sip of beer, interesting processes in the body begin to be triggered. Research shows that even a small amount of alcohol can affect the functioning of the brain, which is expressed through changes in our well-being and perception.
The effect of beer on the release of hormones
Even after drinking the first glass of beer, the brain relaxes the hormone dopamine, known as the “feel-good hormone”. This hormone activates the reward centers, leading to a feeling of pleasure and relaxation. Dopamine helps us feel pleasure, but its effect is short-lived. When drinking alcohol, the blood sugar level can drop, which is especially pronounced if you drink it on an empty stomach. This drop in sugar often causes mild dizziness and cravings for snacks, which is a typical reaction of the body.
Gender differences in response to alcohol
Men and women react differently to alcohol, even when they consume the same amount. Studies show that they do women's 30-40 % a stronger reaction than men after the same amount of alcohol. The reason for this is in the body composition, as women have a smaller amount of body water and more body fat, which affects the rate of metabolism of alcohol. The different body composition causes alcohol to break down more slowly in women, which means a longer effect in the body.
Alcohol and adolescent brain development
Research shows that alcohol consumption has a significant impact on the development of the adolescent brain, which is still developing. Using brain scans, scientists have found that alcohol suppresses the functioning of the frontal lobes of the brain in young people. These frontal lobes are crucial for thinking, planning, and impulse control.
In young people who have consumed alcohol, the ability to focus and self-control is significantly reduced, leading to unpredictable decisions and behavior.
Influence on emotional responses and behavior
In addition to the physical effects, alcohol also affects our emotional responses. When alcohol inhibits the functioning of the frontal lobes of the brain, it becomes more difficult to control emotions and impulses. People can be more relaxed, but also less attentive to the consequences of their actions. Lack of control leads to behavior that is often reckless, as alcohol impairs the ability to judge properly.
Do not forget
Alcohol is not an innocent companion to a pleasant evening, but it can quickly cause changes that we may not even be aware of. Let's be responsible when drinking and take care of ours health and well-being.
