While being the most popular legal drug in UK, there are many short-term and long-term effects of alcohol. Some effects of alcohol can be seen as desirable, such as euphoria and increased self-confidence at lower amounts, or unpleasant – dizziness, vomiting and blurred vision at larger amounts.

The effects of alcohol are felt more or less depending on circumstance and physiology. Women become intoxicated after drinking less alcohol than men, and consuming alcohol after a heavy meal will lessen the physical effects of alcohol.

Effects of alcohol - short-term effects of alcohol

Consumed in moderation, the short-term effects of alcohol are typically safe and pleasant, in fact, one beer is known to increase sleep time and reduce awakening during the night. This beneficial physical effect of alcohol is not seen when more than one beer is consumed. The effects of alcohol when consumed in excess of one drink disrupts sleep cycles and causes daytime fatigue.

The short-term effects of alcohol are dependent on how much alcohol is consumed, and thus how much alcohol is in the blood (the blood alcohol level). The effects of alcohol also vary depending on the alcohol tolerance of the drinker.

The effects of mild drinking (1 – 4 drinks depending on gender and size):

  • Increased mood and possible euphoria
  • Increased self-confidence, sociability
  • Shortened attention span
  • Flushed appearance
  • Inhibited judgement
  • Impaired fine muscle coordination

More negative effects of alcohol are seen in moderate to heavy drinking (5 – 12 drinks depending on gender and size):

  • Sedation
  • Impaired memory and comprehension, profound confusion
  • Delayed reactions
  • Balance difficulty; unbalanced walk; staggering
  • Blurred vision; other senses impaired
  • Emotional changes
  • Inability to feel pain
  • Impaired speech
  • Dizziness often associated with nausea (“the spins”)
  • Vomiting

Once more than 12 drinks are consumed, only the negative effects of alcohol are present:

  • Stumbling walk
  • Lapses in and out of consciousness
  • Unconsciousness
  • Amnesia
  • Vomiting (possibly life-threatening if done while unconscious)
  • Respiratory depression (potentially life-threatening)
  • Decreased heart rate
  • Urinary incontinence
  • Unconsciousness (coma)
  • Depressed reflexes (i.e., pupils do not respond appropriately to changes in light)
  • Death

Effects of alcohol - long-term effects of alcohol

The National Institute on Alcohol Abuse and Alcoholism recommends women limit their alcohol intake to one drink per day and men limit themselves to two drinks per day. Consuming alcohol in larger than these quantities show the negative effects of alcohol. Long-term effects of heavy alcohol consumption can lead to brain shrinkage, dementia, alcoholism and even death.

There are a few long-term effects of alcohol that are beneficial, however. When alcohol is consumed in the recommended amounts, the following physical effects of alcohol are seen:

  • Reduced risk of death from coronary heart disease
  • Reduced risk of blood clot
  • Reduced risk of gallstones
  • Lower risk of kidney stones
  • Reduced risk of rheumatoid arthritis
  • Increase in women’s bone density
