How does alcohol affect you?

Even small amounts of alcohol affect you. The more you drink, the more intoxicated you become. You may not sense an increase in intoxication, but how you feel does not matter – if you have consumed alcohol you are affected by it and therefore should not drive. It is as simple as that.

Alcohol affects us in the following way:

  • 0.1-0.4 ‰ – Less inhibitions, overconfidence, and longer reaction time.
  • 0.4-1.0 ‰ – Impaired vision and coordination.
  • 1.0-2.0 ‰ – Double vision, clumsiness and balance problems.
  • 2.0-3.5 ‰ – Fall into deep sleep.
  • 3.5-5.0 ‰ – Go into a coma or die.

The per mille numbers above refer to blood alcohol concentration.
