The human body can develop a tolerance to alcohol and there are numerous theories as to why. It has been speculated that alcohol has an effect on the transmission of nerve cell impulses. Specifically, the cell membrane’s sodium and potassium channels are impacted and this leads to the cell membranes becoming more rigid. Tolerance levels increase as a result.
It is also believed cholesterol and/or saturated fat may increase and this contributes to boosted tolerance levels. And then there is the notion extensive alcohol consumption changes the chemicals in the brain. Once again, tolerance levels could increase as a result.
Tolerance brings forth consequences.
When tolerance increases, the person drinking has to consume more alcohol for it to have an effect. The sedative effect is dulled as well. The most serious effect of increased tolerance is the increased consumption of alcohol leads to very high blood-alcohol levels. Extremely high levels of blood-alcohol content could put someone at risk for a fatal reaction.
Studies have even shown that people can absorb alcohol to a very high level and not show the signs of intoxication. To repeat, someone whose alcohol tolerance levels reach such high points could end up drinking to the point the consumption becomes life threatening.
