Alcohol is known as a downer or depressant: it slows down brain activity and can have a calming effect on the body. However, they can also cause low blood pressure, slurred speech, headaches, dizziness, and poor concentration. Drinking alcohol in excess can even lead to a person blacking out, and although it has a calming effect to help you fall asleep, it can later affect your quality of sleep.
After having alcohol, the body’s epinephrine level goes up several hours later, causing heart rates to elevate, resulting in nighttime awakenings. Alcohol can also cause the throat muscles to relax too much, leading to sleep apnea and other breathing problems that can interfere with sleeping. Moreover, frequent drinkers are aware of the groggy hangovers they have the next day, leaving them feeling fatigued. It’s best to reduce one’s alcohol intake if fatigue is a real problem that interferes with the daily operation of your life.
