Alcohol has been shown to cause depression. Depression is a continual feeling of hopelessness, sadness, unhappiness and causes a bleak outlook on life. And when you’re depressed, you can’t be on top of your game. It is difficult to function at full speed when you are fatigued and experiencing a general lack of interest, also caused by depression. It may also be important to note here that depression causes anxiety. Many of those who suffer from depression will also have episodes of anxiety.
Since alcohol is a known depressant, it stands to reason that people with depression should not drink. This also applies to people suffering from manic depression. Studies have shown that approximately 65% of people are misdiagnosed by doctors who are depressed.
Depression caused by alcohol actually begins with your physical body. First, alcohol lowers the levels of serotonin and norepinephrine in your brain. These chemicals are what give you good feelings, a sense of well-being, and help you feel normal. Antidepressant medications were designed to accumulate these chemicals. After a long career as a drinker, since alcohol can reduce these brain chemicals to zero, it can take a long time for antidepressants to bring these brain chemical levels back to where they should be.
Alcohol also temporarily nullifies the effects of stress hormones. That is why after drinking you feel worse than ever, because alcohol depresses your nervous system and your brain. A study was conducted that followed people who only drank one drink a day and after these people stopped drinking for 3 months, their depression scores improved. And that’s just one drink a day, so it’s easy to imagine the impact that the kind of bulk an alcoholic drinks every day can have.
Alcohol almost removes all the vitamins from your system after a drinking session. A deficiency in folic acid will contribute to brain aging and, in older people, dementia. Folic acid deficiency also contributes to general depression. Additionally, the alcohol in your system also breaks down and accelerates the removal of antioxidants from your blood. Antioxidants are vitally important to our health because antioxidants fight free radicals, and free radical damage causes disease and aging. Our immune system actually creates antioxidants which then neutralize free radicals.
Alcohol can activate a gene that has been linked to depression and other mental problems. The result of this activation can cause not only depression, but also seizures and manic depressive episodes.
Although most problem drinkers associate depression with their mental and emotional states, the fact is that this type of depression originates from your physical body’s response to alcohol use.
