You don’t drink and drive so why drink and dive!
In dive training, most of the emphasis regarding the effects of alcohol on diving is placed on dehydration, and the theoretical increase in risk of decompression illness (DCI) that this may cause.
Dehydration happens because alcohol is a diuretic that makes you want to urinate more frequently, thus accelerating fluid loss from the body. This in turn leads to side-effects such as muscle cramps, dizziness and fainting.
But this is only part of the story. Download our leaflet for more information to share with your diving friends: Diving after alcohol
