Alcohol causes cancer, but it can also make you fall asleep faster and more deeply. If you have ever had alcohol, you might have experienced it yourself. Intrestingly, the sedative effects of alcohol are only felt in an environment that is quite, if you are in an active while drinking, you might not even notice it.What Is Alcohol And How Does It Impact Your Sleep? Alcohol is a chemical compound that typically refers to ethanol, the type found in alcoholic beverages like beer, wine, and spirits. It is produced through the fermentation of sugars by yeast, and when consumed, it acts as a depressant on the central nervous system.Once alcohol reaches your brain, it impacts a neurotransmitter called gamma-aminobutyric acid (GABA) that slows down your brain's processing capability. This is why alcohol relaxes your mind. Alcohol also puts the brakes on an excitatory neurotransmitter called glutamate while tapping the reward centres of your brain. Due to this effect, having a drink or two before bed might actually calm down your central nervous system, making it easier for you to fall asleep. You might also notice a difference in your sleep quality. You sleep deeper and harder when you have alchohol in your system. While wine, rum or other forms of alcohol can make you fall asleep almost immediately, it still might help disrupt your average sleep cycle. As per experts, the initial crash might make you believe you'll sleep better, but you will be missing on some of the REM sleep while alcohol is in your system. This is because once your body metabolises alcohol, your sleep will lighten and you are more likely to wake up frequently. You see, alcohol inhibits melatonin, a hormone that signals your body to sleep. Not only that, but alcohol interferes with the melatonin receptors in your brain.However, that doesn't mean you should pop a melatonin gummy while sipping a can of bear. Combining alcohol and melatonin can make you even more drowsy or cause irritability. Alcohol already taxes your liver, and adding a melatonin supplement makes your liver work overtime. This weakens your liver's ability to produce certain enzymes, causing several side effects. Alcohol's Impact On Your BrainPrimarily, alcohol interferes with the brain's communication pathways. According to the National Institutes of Health (NIH), alcohol can also alter how the brain looks and functions. It disrupts the areas of the brain responsible for balance, memory, speech, and judgment, increasing the likelihood of injuries and other negative outcomes. Long-term alcohol consumption can permanently change neural pathways, leading to lasting cognitive and emotional effects.Moreover, it is a proven fact that alcohol can worsen mood swings. Recent research shows that alcohol may exacerbate symptoms of bipolar disorder by destabilizing mood, which impacts efficiency at work. Alcohol also affects conditions like depression, and panic disorder, and can trigger impulsive behaviour. Additionally, alcohol has been shown to disrupt sleep patterns, making it harder to get restorative rest.
