This could cause them to choke and suffocate on their vomit. This causes your body to slow down and become more relaxed. Like alcohol, sedatives can impair your ability to think and make memories.
THC, the psychoactive compound found in marijuana, may also increase blackouts when combined with alcohol. Learn more: Alcohol and anxiety ».
Most reports suggest middle-age males with alcoholism are more likely to black out. Yet, anyone drinking large amounts of alcohol is at risk for blackouts. Young adults in college are also considered at risk. Researchers link that risk to the heavy drinking habits common among many college students. Studies have also found that women may be at greater risk of blackouts even though they generally drink less alcohol less frequently than men.
This may be due to the physiological differences that affect alcohol distribution and metabolism. These include body weight, body fat percentage, and key enzyme levels. 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.
Sleep helps end blackouts because rest gives the body time to process the alcohol. Others, though, can digest liquor while still awake. That means a blackout could last minutes to even days. Although many people recover from blackouts, one episode can be fatal.
In addition to abstaining from alcohol, moderation and pace are important to preventing blackouts. Avoid binge drinking, which is defined as consuming five or more drinks in about two hours for men, or four or more drinks for women.
Like the risk factors, the consequences of blacking out are not only worse for adolescents, but also for women. These women also showed more regret the following day. This is because they are risk while they under the influence due to impaired decision making, especially when it comes to assessing potentially dangerous situations, but they are also at risk afterwards because they cannot rely on their memory of what happened. This means there is a catch Those experiencing blackouts may be more vulnerable to potential perpetrators in the moment.
But if they try to press charges after, they also are vulnerable to having their cases dismissed. Individuals with a history of sexual assault are more likely to be re-victimised if they are in an alcohol-induced blackout Credit: Getty Images. One party being blackout complicates that evidence.
Take Canada, where affirmative consent is necessary. In the US, meanwhile, laws vary by state. But New York, for example, says mental incapacitation can legally result only from involuntarily being given a drink or drug, not from having chosen to drink. Sarah Hepola has ample experience of this kind of disconnect.

This makes blackouts a useful marker and predictor of other detrimental behaviour. For these reasons, questions about alcoholic blackouts are now increasingly being used in screening tools to quickly get at whether someone is a recreational drinker or a problem drinker.
Mary-Beth Miller, an addiction psychologist at the University of Missouri, found that a simple intervention technique could help blackout drinkers reduce their drinking, a finding she first showed in ex-army veterans and then extended to university drinkers. It is an online questionnaire that asks individuals about their drinking habits, and reports back how much they are drinking compared to others who are similar in age and background.

Screening questionnaires about alcohol use now routinely ask about prior blackout experiences, which could make it easier to target and find individuals who need help. Simply asking about the amount an individual has drunk was not found to be effective. These interventions are not time-consuming or expensive, making Miller hopeful that she and colleagues can build upon them to develop even more effective interventions.
Other researchers hope that asking about previous blackouts will in turn help reduce other types of risky behaviour. There are two types of blackouts; they are defined by the severity of the memory impairment. This type is sometimes referred to as a grayout or a brownout. With this severe form of blackout, memories of events do not form and typically cannot be recovered.
It is as if the events simply never occurred. Blackouts tend to begin at blood alcohol concentrations BACs of about 0. At these BACs, most cognitive abilities e.
The level of impairment that occurs at such high BACs makes the intoxication level associated with blackouts especially dangerous. Outages have been on the rise in recent decades, and utilities might be ill-prepared to take on the dual challenge of responding to intensifying weather events and upgrading aging facilities.
When these poles, wires, and transformers went up decades ago, the system was initially overbuilt, with growing demand anticipated, says Alexandra von Meier, an electrical engineer at the University of California, Berkeley. Estimates on just how bad the problem is vary, though. According to an analysis by Climate Central , major outages affecting more than 50, homes or businesses grew ten times more common from the mids to From to , weather-related outages doubled.
In a report, the American Society of Civil Engineers reported that there were 3, total outages in , lasting 49 minutes on average. The U. Energy Administration reports that in , the average utility customer had 1. The reason these estimates vary may be related in part to the fact that private utilities tend to be guarded about sharing data, according to Sayanti Mukherjee, a civil engineer focused on energy resilience at the University of Buffalo.
According to one analysis, the United States has more power outages than any other developed country. Research by Massoud Amin , an electrical and computer engineer at the University of Minnesota, found that while people living in the upper Midwest lose power annually for an average of 92 minutes, those in Japan experience only 4 minutes of blackouts per year.
In a comparison by the Galvin Electricity Initiative , the average utility customer in the U.
