How Long After a Concussion Can You Safely Drink Alcohol?

How long after a concussion can you drink alcohol? Experts recommend abstaining from alcohol for at least 3-4 weeks to aid concussion recovery.

After a concussion, it’s wise to avoid alcohol for 3-4 weeks. This gives your brain the time it needs to heal well.1 If you drink alcohol with a concussion, it’s bad for your recovery. It can make your symptoms worse and increase the chance of more injury.1

Alcohol is like a poison for your brain. It crosses into the brain and messes with how your neurons talk to each other. This change can also affect how blood moves in your brain.1

When you’re drunk, you might make poor choices, talk funny, or forget things. You could also have trouble moving right and be slow to react. This makes you more likely to hurt your head again.1

It’s best to talk to a doctor before you decide to drink while you’re getting over a concussion. The effects can differ based on many things, including how bad your concussion was.

Key Takeaways

  • Experts recommend abstaining from alcohol for at least 3-4 weeks after a concussion to allow the brain to heal.
  • Drinking alcohol during concussion recovery can severely impair brain healing and increase the risk of further injury.
  • Alcohol is a toxin that can disrupt communication between neurons and alter blood flow in the brain.
  • Intoxication can lead to impulsivity, poor decision-making, and other effects that put you at risk of further trauma.

Understanding Concussions and Their Impact

A concussion is a brain injury caused by a hit to the head. It can come from direct impacts, car accidents, or hard falls.2 This hit can lead to brain swelling and temporary cell damage in the affected area. Also, it might change how blood flows to areas of the brain that need it most, affecting neurovascular coupling (NVC). This mix of issues can bring on a range of post-concussion symptoms like headaches and trouble focusing.2

What is a Concussion?

Many people get better within weeks.3 But some, as many as 30%, don’t fully recover for a long time. This is called post-concussion syndrome.2

Symptoms of a Concussion

Common symptoms are headaches, dizziness, feeling sick, and being unclear about what’s going on.2 People might also feel tired or have mood changes. The way these show up can be different for each person. It all depends on how they got hurt and their own health.

The Importance of Proper Healing

Getting over a concussion the right way is very important.2 Risk is higher for more serious problems if someone keeps getting concussions. Long-term, these might include trouble remembering things, feeling sad or worried a lot, always feeling sore, having seizures, or acting differently from before.2 If you see a doctor right away and stick to your treatment plan, including taking it easy, possibly some meds, and maybe some therapy, you’re more likely to get completely well.2

It won’t happen overnight, though. Patients need time to recover fully.3

The Effects of Alcohol on the Brain

Alcohol is a toxin that goes directly to the brain through the blood.4 The liver usually breaks down alcohol. But, the brain can get rid of some alcohol itself too. Alcohol messes up how brain cells talk to each other. This can change how blood moves in the brain, affecting our thinking and actions.4

How Alcohol Affects a Healthy Brain

Getting drunk can change how your brain works. This might make you act without thinking, make bad choices, talk unclearly, forget things, and not be able to move properly. It slows how fast you react too.4 Alcohol can also make us feel happy for a bit, but it’s not good for the brain. This is especially true if someone has had a concussion or a brain injury.

Alcohol and Impaired Cognitive Function

Alcohol messes with how brain cells talk and how blood moves in the brain, hurting our thinking skills.4 It can make us less focused, mess with our memory, and cause problems when we need to solve something. Our judgment gets off, and we make bad choices.4 For people healing from a concussion or brain injury, this is a big issue.

Alcohol and Concussion Recovery

While getting over a concussion, doctors advise avoiding alcohol. It can seriously hurt brain healing and make symptoms worse.4 Drinking after a head injury slows down recovery.4 People often feel alcohol more after a brain injury.4 It might delay healing from a TBI and raise injury risks.1 Around 30% of concussion cases lead to long-lasting symptoms.

Potential Risks of Drinking During Recovery

Alcohol messes with sleep, key for getting better.4 It raises the chances of seizures for TBI patients.1 Falling or coordination issues might also lead to more harm.1 Drinking worsens symptoms for 35% who list post-concussion depression.4 It hits a hard note, especially for those fighting depression already.

Recommendations from Medical Experts

Top medical groups like the Brain Injury Association advise against alcohol. They say wait until you’re fully healed.4 The CDC highlights that drinking or unapproved drugs can slow healing and risk more damage.4 Adults with brain injuries suffer more from alcohol.4 Yet, most get back to normal, but some signs need expert eyes.

Alcohol Intolerance After a Concussion

Symptoms of Post-Concussion Alcohol Intolerance

After a concussion, drinking alcohol affects everyone differently. For some, it brings more energy instead of making them tired. On the other hand, some feel worse, reporting more intense symptoms like headaches and nausea. They also feel extra sensitive to light and sound, struggle to sleep, and have trouble thinking clearly.3

They may describe this as a hangover that is much worse. Their concussion symptoms might even seem to intensify for a brief period. Others might react by sleeping a lot, up to 18 hours, after they’ve been drinking. This response varies from person to person, and it depends on factors like concussion severity and brain chemistry.3

If you’re taking medicines for your post-concussion symptoms, mixing them with alcohol might lead to unwanted effects. This goes for medications like anti-depressants or painkillers.3

how long after concussion can you drink

Most experts say to avoid alcohol for 3-4 weeks after a concussion. This helps your brain heal well.1 The exact time to wait can change based on how bad the concussion was and how you’re getting better.

Doctors might tell you to wait until all your symptoms are gone before drinking again.4 If alcohol makes you feel worse or you get bad reactions from it, don’t drink. Wait until your doctor says it’s okay.4

Always talk with a doctor before deciding to drink alcohol while you’re recovering from a concussion. They can give you advice that fits you exactly.

Concussion Recovery Timeline

The typical concussion recovery involves three main phases. These are the acute phase, the recovery phase, and the recovered phase.1

Acute Symptomatic Phase

In the first days or weeks after the injury, patients enter the acute phase. Here, symptoms like headaches, dizziness, and cognitive issues are common.

Recovery Phase

The recovery phase starts next and usually lasts 1-2 weeks. During this time, symptoms lessen as the patient gets better.

Recovered Phase

When brain function goes back to normal and symptoms disappear, the recovered phase begins. This stage usually takes 1-2 weeks. But, for some people, especially those with severe concussions, it might take up to 3 months.1

Alcohol and Post-Concussion Syndrome

After a concussion, some people might take longer to get better. This is called post-concussion syndrome. Symptoms can last over 3 months.1 Drinking alcohol during this period can make things worse. It can impact headaches, thinking, balance, and sleep.5 Drinking also raises the chance of more injuries. Alcohol affects balance, coordination, and decision-making, increasing the risk of falls or accidents.5

Worsening of Symptoms

Alcohol makes the symptoms of post-concussion syndrome worse. It can increase headaches, thinking issues, trouble with balance, and bad sleep.5 This makes getting better harder and extends the time it takes to return to normal.

Increased Risk of Further Injury

Drinking can lead to more injuries if you’re dealing with post-concussion syndrome.5 It causes trouble with balance, coordination, and making decisions. This leads to more hurdles in getting better and could cause long-term problems.

Experts strongly warn against drinking for those with post-concussion syndrome. Drinking can slow down recovery and lead to worse long-term effects.1

Reverse Alcohol Tolerance

After a concussion, some people face a strange issue. They may feel drunk with just a few sips of alcohol. This happens because their bodies can’t handle alcohol like before.1 So, they struggle with balance and may get hurt easier.6

Liver Damage and Other Health Risks

Drinking alcohol might also harm your liver more if you’ve had a concussion. It could lead to serious health issues like an irregular heartbeat or liver cancer.6 People healing from a concussion need to be extra careful with alcohol. The risk of health problems is higher for them.

3.8 million Americans suffer a concussion due to a sports-related injury yearly.6
An estimated 5% to 10% of athletes experience a concussion in their lifetime.6
Around 300,000 of the roughly 3.8 million concussions reported yearly involve football players.6
1 in 8 people in the U.S. have an alcohol use disorder (AUD).6
It takes, on average, 1 to 2 weeks for most people to get through the three phases of concussion recovery.6
Alcohol consumption slows down the time it would otherwise take to heal from a concussion.6
Alcohol consumption increases an individual’s chances of suffering additional head and other bodily injuries.6
Reverse alcohol tolerance refers to the liver’s inability to produce the enzymes necessary to break down alcohol.6
Alcohol consumption can lead to liver and other health problems such as alcohol use disorder, irregular heartbeat, breast cancer, cirrhosis, liver cancer, heart disease, hypertension, stroke, and oral and upper digestive tract cancers.6

Alcohol and Medication Interactions

People with concussions take many medications for their symptoms. These include pain relievers and anti-depressants. Medications for better focus and sleep are also common. It’s crucial to know that alcohol can mix badly with these medications. This might make side effects worse or reduce how well the treatment works.4

For instance, alcohol and anti-depressant drugs don’t go well together. Many patients with concussions and depression take these medications. Drinking when on medication for headaches or cognitive problems is also risky.4 Always talk to your doctor before you drink during your recovery. They can warn you about any bad effects of alcohol with your meds.

If you mix alcohol with meds, it can make some meds not work right. It can also make some meds too strong, possibly leading to an overdose.7 The bad mood from drinking can last for a long time. Plus, alcohol is a type of drug that makes you feel down. This can cause depression or make it worse.7

After a head injury, people are much more likely to get depressed in the year that follows. This happens 8 times more than in the whole population. So, it’s best to steer clear of alcohol when you’re on prescription meds during your concussion recovery.7 Always talk to a specialist doctor about your meds and alcohol. This way, you can make sure your recovery is safe and effective.

Responsible Drinking After Treatment

After getting treatment for your post-concussion syndrome, if you plan to start drinking alcohol again, be careful.1 Was alcohol bad for you before treatment? If so, wait a while before trying it. Start with a little and watch how you feel. Gradually, drink more over a few days. Don’t rush into having a lot at once.3

Gradual Reintroduction of Alcohol

Watch closely for any old or new concussion symptoms coming back. This includes headaches, feeling dizzy, thinking slow, or having trouble with balance.1 If symptoms return, stop drinking alcohol until you feel better again.3 Always, talking to your doctor is smart before having any alcohol again.

Monitoring for Symptom Relapse

Tune in to how your body handles alcohol as you recover. Some people find their headaches, sickness, or feeling dizzy gets worse after a drink.1 Others might feel more energetic or sleepy after drinking. For a few, any alcohol could be too much post-concussion.1 Drinking might also mess up your sleep, or make your balance and movements worse.1 After treatment, if alcohol brings symptoms back, it’s not that your treatment failed. It just might make you feel worse for a bit.1

Factors Affecting Alcohol Tolerance After Concussion

After a concussion, how someone handles alcohol can really change.1 It depends on their brain’s chemistry, how their body processes food and drink, and their general health.4 Also, the severity of the brain injury from the concussion and the affected brain areas matter. This affects how alcohol is handled while the brain is healing.4

Individual Variations

For some, even a little alcohol can bring big problems. Others might find they can drink moderately without issue.4 Talking to a doctor who knows their story can offer special advice on drinking again safely.

Severity of the Concussion

How bad the concussion was and which parts of the brain were hurt also affect how the body deals with alcohol.4 Some folks might notice lots of problems after drinking, like headaches, feeling sick, dizzy spells, or trouble with light and loud sounds.1 One tale tells of a person losing eyesight in one eye after drinking.1
