COVID-19 and alcohol use: Why managing your alcohol consumption is crucial during the COVID-19 pandemic

COVID-19 has taken the world by storm. It has forced countries to shut down and people to self-isolate. While self-isolation and shutdowns are effective methods of preventing the spread of COVID-19, they come with collateral effects. A recent report published by the Canadian Centre on Substance Use and Addiction (CCSA) found that 25% of Canadians (aged 35-54) are drinking more while at home during the COVID-19 pandemic due to boredom, stress, and/or a lack of regularity in their schedules.

A similar increase was seen in Australia, where there was an increase of around 30% in alcohol bought compared to last year. Alcohol is used as a way to relax by many, but it can harbor many negative effects in a time such as the COVID-19 pandemic.

The World Health Organization (WHO) has recently debunked the misconception that drinking alcohol can provide you extra immunity against the Coronavirus.

In contrast, a study concluded that alcohol might increase vulnerability to the Coronavirus. Alcohol consumption at levels such as 5 – 6 drinks at a time or having more than 14 drinks in a week has a role in disrupting one’s immune system. It can do so by disrupting physical, chemical, and cellular responses that are a part of the body’s first line of defense. Furthermore, alcohol can impair t-cell recruitment which lowers the number of white blood cells that can destroy the invaders, which weakens the immune system. This is dangerous, especially with COVID-19 looming, as a weaker immune system leaves you more susceptible to infections.

Alcohol can not only damage the immune system, but there is also a growing concern that the sudden increase in alcohol usage during the pandemic may result in greater cases of alcoholism. Alcoholism can lead to many health problems ranging from mental disorders to liver/heart problems. In a family setting, this can result in domestic violence and child negligence, contributing to the development of many other long-term problems such as Post-Traumatic Stress Disorder and depression.

The future is dependent on what actions people decide to take now. The increase in alcohol drinking can become a problem if not addressed properly. The way to prevent an increase in alcoholism and all of the consequential problems attached to it is to lower your alcohol intake to a low-to-moderate amount (maximum of 1 -2 drinks a day).  The effects of COVID-19 are here to stay for many years to come and if alcohol consumption is not controlled during this time, it will only add to the persistence of these effects.

COVID-19: Could the common cold help protect you?

The common cold is never any fun to deal with, however a past cold might also provide you with some protection from COVID-19, a recent study suggests by the University of Rochester Medical Center.

Research from infectious disease experts at the University of Rochester Medical Center have also suggested that people who have had COVID-19 may be immune to it for a long time, possibly even for the rest of their lives.

What’s the foundation?

Even though the virus that causes COVID-19 (SARS-CoV-2) is relatively new, it falls under a category of beta coronaviruses that cause about 15–20% of common colds.

When you catch a cold, your body fights against the virus through your immune system. While your body does this, the immune system “remembers” the virus for the future. This is so the next time that virus enters your system, your immune system will be able to fight back even faster.

The evidence

The study is the first to focus on memory B cells — immune cells that can last for decades. Since memory B cells can survive for decades, they could protect COVID-19 survivors from future infections for a long time — but further research is needed to confirm this.

The researchers compared blood samples from 26 people who were recovering from mild to moderate COVID-19 symptoms and 21 healthy people who had their samples collected 6–10 years ago — long before they could be exposed to COVID-19.

The study found that B cells from the immune system that attacked previous cold-causing coronaviruses seemed to also recognize the coronavirus (SARS-CoV-2) that causes COVID-19 as a result of memory B cells being activated.

“When we looked at blood samples from people who were recovering from COVID-19, it looked like many of them had a pre-existing pool of memory B cells that could recognize SARS-CoV-2 and rapidly produce antibodies that could attack it,” said study authour Mark Sangster.

The study authors believe this could mean that anyone who has ever been infected by a common coronavirus — which is almost everyone — may have some amount of immunity to COVID-19. This means that if you were to be infected with COVID-19, the severity of your symptoms would be lower compared to those without pre-existing memory B cells for a common coronavirus.

What’s for the future?

The researchers will “need to see if having this pool of pre-existing memory B cells correlates with milder symptoms and shorter disease course — or if it helps boost the effectiveness of COVID-19 vaccines,” said study co-authour David Topham.

What can you do now?

While a past common cold may help lessen the symptoms of COVID-19, it does not mean that you should be trying to catch a cold. Instead, health officials advise for people to get their flu shots this season to reduce serious health complications and an additional burden on the health care system.

Failure to Communicate

Introduction 

Right now communicating science to the general public is more important than ever, and we are failing. Less than 50% of Americans say they would receive a vaccine for COVID-19. This shows the eroding trust that the public has for their once highly esteemed scientist. This is the result of breakdowns in the scientific method that have led to conflicting information being shared with the public.

Mask  Wearing

Perhaps the most notable slip up was the controversy surrounding masks.  While recommended now, it was not until April 3rd, three months into the pandemic, that the CDC began recommending the general public to wear a mask. This was in direct conflict with their earlier statements that only healthcare workers needed masks.  Scientists rushed conclusions that could not be properly verified before being shared with the public. The public demanded answers from a process that can take years, in a matter of weeks. By caving in to public demand, the CDC and World Health Organization were inevitably set up for failure as the pandemic progressed and more data was collected leading to new developments. Tweets from the U.S surgeon general like this

Tweet by Surgeon General Feb 29

only serve to fuel distrust when compared with tweets he makes a few months later.

Tweet by Surgeon General June 14

 

I do not fault scientists for changing their opinion as new data became available, but I do fault (some) scientists for stating their answers with confidence when the proper research and review had not been conducted.

 

Treatment

Scientists have been under enormous pressure to find treatments for COVID-19 that can reduce mortality and infection rate. This has created haste in the scientific method and has allowed some treatments to receive emergency authorization from the FDA such as remdesivir. Even these emergency authorizations are accompanied by randomized, double-blind, placebo-controlled clinical trials that assure treatments are safe. These methods for testing were not present in the study of Hydroxychloroquine that led to its eventual emergency authorization.  The original study involved only 26 patients treated with Hydroxychloroquine that were compared to 16 untreated patients at a different hospital. Later studies conducted on Hydroxychloroquine would question its effectiveness as a treatment for COVID-19 and thus the scientific process was able to correct itself and the FDA revoked the use of Hydroxychloroquine. However, the public once again lost its trust in doctors. This opened the door to rumors and conspiracy theories to dominate the public view. In a pandemic where time is everything the spread of misinformation costs lives

By allowing leniency in the scientific method, we have opened the flood gates to all types of information being thrust onto the pedestal once reserved for the conclusion from the scientific method. Your uncle’s Facebook post about the healing power of Clorox bleach carries as much weight as the cutting edge research on COVID-19. Scientists have lost credibility with the public. This is not the first time this has happened, but it may be the most damaging.

COVID-19 and Alcohol Use: Why Managing Your Alcohol Consumption is Crucial During the COVID-19 Pandemic

The Now

COVID-19 has taken the world by storm, forcing whole countries to shut down and people to self-isolate. Whilst self-isolation and the shutdowns are effective methods of preventing the spread of COVID-19, they also have their collateral effects. A recent report published by the Canadian Centre on Substance Use and Addiction found that 25% of Canadians (aged 35-54) are drinking more while at home during the COVID-19 pandemic because of either boredom, stress, and/or lack of a regular schedule.

A similar increase was seen in Australia where there was an increase of around 30% in alcohol bought compared to last year. Alcohol while being a great way to relax also has many negative effects that in a time such as the COVID-19 pandemic can result in some very dangerous situations.

The Truth 

One misconception about alcohol that has been debunked by the World Health Organization (WHO) was that drinking alcohol can provide you extra immunity against the COVID-19 disease.

In contrast, a study concluded that alcohol might increase one’s vulnerability to the COVID-19 disease. Alcohol consumption has a documented role in disrupting one’s immune system. It can do so by disrupting physical, chemical, and cellular responses that are apart of the body’s first line of defense. Furthermore, alcohol can impair t-cell recruitment which means there is a lower number of total white blood cells that can go out and destroy the invaders, this results in a weaker immune system. This can be dangerous especially with COVID-19 looming as a strong immune system can help fight off COVID-19 with ease but with a weak one COVID-19 becomes a much greater threat.

From this, it can be understood that limiting the number of alcoholic drinks that you intake to a low-to-moderate amount will be beneficial for you.

Dr. Charity Baker states “Alcohol isn’t healthy and never was”

Alcohol can not only damage the immune system, but there is also a growing concern that the sudden increase in alcohol usage during the COVID-19 pandemic may result in greater cases of alcoholism. This is a concern as it can lead to many health problems that range from mental disorders to liver/heart problems; in a family setting, this can result in domestic violence and child negligence which can develop into many other long-term problems such as Post-Traumatic Stress Disorder (PTSD).

The Future 

The future is dependent on what actions people decide to take now. The increase in alcohol drinking which is collateral of COVID-19 can become a problem if not addressed properly. The way to prevent an increase in alcoholism and all of the consequential problems is to lower your alcohol intake to a low-to-moderate amount, which is considered to be a maximum of 1 -2 drinks a day.  The societal and economical effects of COVID-19 are here to stay for many years. If alcohol drinking is not controlled during this COVID-19 pandemic, these effects will also persist for many more years to come.
