What Are Blackouts? – Alcohol-related blackouts are gaps in a person’s memory for events that occurred while they were intoxicated. These gaps happen when a person drinks enough alcohol to temporarily block the transfer of memories from short-term to long-term storage—known as memory consolidation—in a brain area called the hippocampus.

What are the dangers of blackouts?
The Dangers Of Blacking Out – Due to the high level of intoxication needed to experience a blackout, decision-making and other psychological processes are very likely to be impaired during this period. When an individual blacks out, he or she will continue to hold conversations and engage in activities like normal.
- In fact, outside observers are typically unaware that an individual is blacked out.
- Depending on how much alcohol the person drank and how impaired other brain functions are, a person in the midst of a blackout could appear incredibly drunk – or barely intoxicated at all.
- This is extremely dangerous as the person may attempt to drive, have unsafe or non-consensual sex, or perform other risky behaviors that can lead to harmful and potentially life-threatening situations.
During a blackout, an individual is capable of participating in salient, emotionally-charged events but will have no recollection of what has occurred. Many people indicated that they later learned they had engaged in a wide range of risky activities during their blackouts – such as having unprotected sexual intercourse, vandalizing property, or driving a car – which could have led to serious health or legal consequences.
- Dr. Aaron White Ph.D., Assistant Research Professor of Psychiatry at Duke University Even experiencing one blackout can be dangerous.
- According to the National Institute on Alcohol Abuse and Alcoholism, alcohol delays signals in the brain that control the gag reflex and other autonomic responses.
- A person who has blacked out could throw up while sleeping due to loss of reflex control and potentially choke or suffocate on their own vomit.
Blackouts also make an individual more susceptible to injury from falls and other accidents. In addition to these immediate dangers and possible trauma, there are also long-term health consequences from blacking out. Heavy drinking to the point of blacking out can cause degenerative problems and have lasting effects on the brain.
Can you pass out from too much alcohol?
As BAC Increases—So Do the Risks – As blood alcohol concentration (BAC) increases, so does the effect of alcohol—as well as the risk of harm. Even small increases in BAC can decrease motor coordination, make a person feel sick, and cloud judgment. This can increase an individual’s risk of being injured from falls or car crashes, experiencing acts of violence, and engaging in unprotected or unintended sex.
When BAC reaches high levels, blackouts (gaps in memory), loss of consciousness (passing out), and death can occur. BAC can continue to rise even when a person stops drinking or is unconscious. Alcohol in the stomach and intestine continues to enter the bloodstream and circulate throughout the body. It is dangerous to assume that an unconscious person will be fine by sleeping it off.
One potential danger of alcohol overdose is choking on one’s own vomit. Alcohol at very high levels can hinder signals in the brain that control automatic responses such as the gag reflex. With no gag reflex, a person who drinks to the point of passing out is in danger of choking on his or her vomit and dying from a lack of oxygen (i.e., asphyxiation).
How long should a blackout last?
How long do rolling blackouts last? – You might wonder: How long do rolling blackouts last? The answer depends on the severity of the supply shortfall and the persistence of peak demand. Sometimes they last an hour or two; sometimes longer. Excessive demand can quickly spike, requiring companies to take fast action to protect the grid.
Can you remember after blacking out?
If you have had a complete blackout, you will likely not be able to remember anything from the experience. With a fragmentary blackout, you may have some recollection of events, and you may be able to recall certain memories with cueing (meaning verbal or visual reminders of the events).
How long does blacking out last for?
– Alcohol-induced blackouts differ from person-to-person. The amount you drink, how long it took you to drink, and your physiology play a role in your blackout. These factors also affect how long the blackout will last. A blackout ends when your body finally absorbs the alcohol and your brain can make memories again.
Can you tell if someone is in a blackout?
A person in a blackout will not remember something that happened a few minutes ago. Thus, if the person doesn’t seem to know what you are talking about or has no memory of what happened, assume they are in a blackout and do NOT leave them alone.
How do I know if I passed out?
Warning Signs For Simple Fainting Dizziness (light-headed), blurred vision, nausea, sweating, feeling cold. These last for 5 to 10 seconds before passing out.
Can anxiety cause blackouts?
Psychogenic Blackouts: Stress and Anxiety – Stress and anxiety are the most common causes of psychogenic blackouts. This can be due to chronic stresses, such as being foreclosed on or having someone close to you pass away. Psychogenic blackouts are, however, more commonly associated with a single stressful event.
Can you blackout and not have a concussion?
To truly have a concussion, you must lose consciousness or “blackout” – Only five to 10 percent of concussions result in a loss of consciousness. A concussion is an injury from a direct blow to the head, neck or face. Or a force directed somewhere else in the body that transfers the force to the head.
