Alcohol Affects the Nervous System: What effects does alcohol have on the nervous system and brain? Learn how it changes mood, thinking, and behavior.

Alcohol Affects Nervous System: Have you ever noticed that as soon as the effect of alcohol begins, a person's mood , way of thinking, and even speech changes? Sometimes it makes a person more cheerful and open, and sometimes angry or sad . Actually , there is a very interesting science hidden behind this . Alcohol affects not only the body but also the nervous system . 

This is the reason why even a small amount of drink changes the functioning of the brain . Let us know, from the opinion of experts , why and how this effect occurs after drinking alcohol .

Dr. Sarin explains that alcohol quickly enters the bloodstream from the stomach and intestines . From there, it travels directly to the brain. It directly affects brain cells, or neurons , that control our body's movement, thinking, and emotions. This can cause a person to feel lighter or more confident.

How is the nervous system affected?

• Our nervous system is divided into two parts , Central Nervous System (CNS) and Peripheral Nervous System (PNS) .
• Alcohol's biggest impact is on the CNS . The parts of the brain that handle thinking, understanding, and decision-making slow down .
• The PNS transmits messages from the brain to the limbs. Alcohol also disrupts this messaging system . This is why a person's balance is impaired and their limbs don't function properly.

Why does alcohol get into your head?

• Blood Alcohol Concentration: The higher the BAC , the faster and more severe the effects will be felt.
• Empty Stomach: Drinking alcohol on an empty stomach makes it work faster.
• Metabolism: Every person's digestion and metabolism are different, so the effects are also different.

The relationship between alcohol and sleep

Many people believe that alcohol induces sleep, but experts say it impairs sleep quality. Alcohol affects the part of the brain that controls deep sleep . Therefore , although you may fall asleep quickly after drinking, fatigue and headaches in the morning are common.
