Shaking after drinking alcohol: Causes, symptoms, and when to worry

Preface

You wake up at 12 pm with no memory of how you got home last night. Someone has opened the curtains, and there’s a glass of juice on the bedside table. As you reach out, you notice your heart is racing slightly faster, and your hands are shaky. Don’t panic. Shaking after drinking alcohol is surprisingly common, and you can reduce alcohol tremors or even prevent them entirely. 

You don’t have to spend every day after a party feeling restless and hungover. It’s time to learn all about post-drinking symptoms to make them less alarming.

 

Can alcohol cause shaking after drinking?

Yes. Shaking, a burning feeling in your stomach, headache, fatigue, and more are all common after drinking. Many people experience mild tremors accompanied by other symptoms the morning after heavy drinking. They occur as your body fights to deal with alcohol. 

1. Nervous system stimulation

Alcohol disrupts your brain’s transmitters and slows down the nervous system. After drinking, these disruptions overstimulate your brain. That’s what leads to the shakes. These involuntary tremors occur when your overexcited brain sends uncoordinated signals to your muscles, causing them to fire irregularly.

2. Dehydration

Drinking makes your kidneys retain less fluid, causing you to urinate more and lose excess body fluids. This causes mild dehydration and can lead to headaches and fatigue. 

3. Poor sleep

Alcohol disrupts your sleep cycle. You will likely fall asleep faster when drunk, but your sleep is likely fragmented, and you’ll wake up earlier. Thus, you sleep poorly and experience fatigue.  

4. Anxiety after drinking

This is also known as hangxiety. Once alcohol wears off the following morning, there’s a chemical rebound in the brain. As the brain reverses the chemical balance, it can cause a hyperexcited state, leading to anxiety. 

 

Why do you experience shaking after drinking alcohol?

Alcohol hangover tremors are a result of how alcohol interacts with your body’s nervous system and how your body processes it. Once you stop drinking, several biological mechanisms can lead to alcohol shakes. They include:

1. Nervous system rebound 

When you drink, alcohol creates that relaxed feeling by quieting your brain — specifically by reducing activity in the receptors that respond to GABA, a neurotransmitter that calms the nervous system. But once the alcohol wears off, your brain scrambles to rebalance itself and often swings too far in the opposite direction. That sudden overstimulation is what leaves you feeling jittery and on edge —and yes, it can absolutely cause shaking.

2. Blood sugar drops

When you drink, your liver shifts its focus to breaking down the alcohol as a top priority. That means it puts other jobs on hold — including releasing stored glucose to keep your blood sugar stable. As a result, your body’s blood sugar levels can drop. And when it gets too low, it can leave you feeling shaky, weak, and off.

3. Dehydration and electrolyte imbalance

Alcohol makes you pee more — a lot more. And every time you go, you’re not just losing water; you’re also flushing out essential electrolytes like sodium and potassium. When those levels drop too low, your muscles can start twitching and spasming on their own. That’s part of what’s behind the shaking in your hands after a night of drinking.

4. Increased adrenaline and stress hormones

You may feel unusually alert and uneasy after drinking. That’s your body flooding itself with adrenaline and other stress hormones to counteract alcohol’s depressant effects. Once the alcohol starts wearing off, those hormones stick around — leaving you feeling unnaturally alert, anxious, and shaky. It’s basically your system stuck in fight-or-flight mode long after the party’s over.

Other signs alcohol is affecting your nervous system

Shaking is only one of several alcohol-related symptoms. As alcohol leaves your bloodstream, it can trigger several physical and neurological side effects. These symptoms include:

1. Trembling hands: Your hands may shake randomly and involuntarily as your nervous system struggles to find a sober state without the sedative effects of alcohol. 

2. Internal shaking or restlessness: The brain’s chemical imbalance as alcohol leaves the body triggers a fight or flight response. This makes you restless. 

3. Racing heart: Dehydration causes low blood volume, making your heart beat faster. Moreover, an increase in adrenaline and stress hormones can raise your heart rate. 

4. Anxiety after drinking: As alcohol leaves your body, there’s a surge in glutamate, the stimulating neurotransmitter. This overrides your body’s calming mechanism, leading to anxiety.

5. Sleep disruption: Alcohol messes with your REM sleep — the deep, restorative stage where your brain actually recovers. Instead of sleeping soundly, you might find yourself waking up multiple times throughout the night or jolting awake earlier than usual. So even if you were in bed for eight hours, you never really got the rest you needed.

6. Sensitivity to light or sound: Since your nervous system is overstimulated as it tries to restore chemical balance, it’s stuck in a state of high stress. That makes your brain extra sensitive to light and sound.

How long do post-drinking shakes last?

Tremors after drinking usually show up about 6 to 12 hours after your last drink. The good news? Mild shaking often improves within several hours to a day. But how long they actually last depends on a few things:

How much you drank: The more alcohol your liver has to process, the longer your body needs to recover. More drinks usually mean longer-lasting shakes.

Your hydration level: Sipping water before, during, and after drinking can help minimize dehydration. And that alone can shorten how long those tremors stick around.

Sleep quality: If you were well-rested before drinking, the fragmented sleep you get afterward won’t hit as hard. So your sleep before and after actually plays a role in how long you’ll feel shaky.

Your overall health: Your liver does the heavy lifting when it comes to breaking down alcohol. If your liver health isn’t great or you have other health conditions, your body may take longer to bounce back — and those shakes might linger.

How to reduce shaking after drinking alcohol?

Drinking alcohol is fun for relaxing and letting loose, but hangovers are the undesired side effect. While there is no magic potion to make them disappear, you can reduce how long symptoms like shaking last. Time is the ultimate cure for alcohol hangover tremors, but these practical steps can make the recovery process a lot easier.

1. Hydrate with water or electrolytes

Rehydration eases your hangover symptoms and reduces shaking. Drinking water, fruit juices, electrolyte-rich drinks, and bone broth can help restore your fluid balance. 

2. Eat a balanced meal

Eating healthy fats, protein-rich foods, and complex carbohydrates can aid your recovery. These can stabilize your blood sugar. You can also eat before drinking to reduce alcohol absorption into the bloodstream.

3. Rest and allow your body to recover

Stay in bed as much as you can, catch a ride instead of walking, and avoid intensive physical activities. Every hangover remedy out there works better when paired with rest. Besides, since alcohol already disrupts your sleep, pushing through the day exhausted will only make symptoms like shaking feel worse.

4. Support recovery before drinking

You can prepare for hangover shaking in advance by hydrating and using nutritional support. Vitamin products such as UPSWING help your body deal with post drinking anxiety by protecting your liver from acetaldehyde damage. 

 

5. Limit alcohol intake next time

Since the likelihood and severity of alcohol nervous system effects depend on how much you drink, moderate drinking goes a long way. It helps to know your limit or set a maximum number of drinks beforehand.

How to prevent shaking the next time you drink alcohol

Prevention is better than cure. So, although you can reduce tremors after drinking alcohol, won’t it be better to avoid them entirely? Making the adjustments below can help reduce the usual dry mouth, shaking, and fatigue after a night out. 

1. Avoid drinking on an empty stomach

A full belly prevents gastrointestinal irritation by acting as a physical buffer between alcohol and the stomach lining. Foods like oils, chicken, and whole grains also reduce the risk of low blood sugar. 

2. Sip water while you drink

Alcohol is a diuretic, meaning it increases urination and makes your body lose fluids more quickly. Thus, alternating alcohol with water helps restore lost fluids, keeping you hydrated. This is crucial since dehydration can cause or worsen body tremors. 

 

3. Pace yourself

Limit your alcohol consumption to about a drink every hour. This prevents alcohol from quickly building up in your bloodstream. Pacing yourself also allows your liver time to process alcohol before the next drink.

4. Stop drinking several hours before sleep

You can enhance the quality of your sleep after drinking by stopping several hours before bed. Allowing your body to process alcohol reduces interference with your REM sleep, enabling better rest. 

5. Take vitamins 

You can prepare your body to deal with a night of drinking and hangovers the morning after by taking vitamins. UPSWING supplements replenish essential nutrients like vitamin B, which are depleted by alcohol. That alone can help prevent the neurological effects that cause you to shake after drinking. UPSWING also helps clear out those nasty byproducts that alcohol leaves in your body and gives your immune system a hand with repair. When you prep in advance, you're basically taking some of the load off your nervous system — which means those post-drinking tremors might not even show up.

 

When does shaking after drinking become a warning sign?

Regular alcohol tremors should go away within a day. If they don't, it could be a sign of something more serious. You should seek medical help if the shaking is:

1. Severe or persistent: Alcohol tremors are typically mild and subside quickly. If they last for more than 24 hours or the shaking is violent, it's worth getting checked out.

2. Accompanied by sweating or confusion:  Feeling a bit foggy is normal after a rough night, but if you're genuinely confused, can't focus, or feel out of it, that's not just a hangover, probably signs of Delirium Tremens. That might be life-threatening. 

3. Happening even after small amounts of alcohol: If you notice you're shaking after just one or two drinks, your body might be reacting differently to alcohol than it should.

4. Worsening over time: Shaking should get easier over time as your liver clears alcohol from the system.  If the shaking is intensifying, it's time to talk to a professional.

5. Along with severe abdominal pain: Intense pain in your stomach or sides isn't normal post-drinking discomfort. It could signal issues with your pancreas, liver, or other organs.

6. If you notice blood: Whether it's in your vomit or your stool, blood is never a normal part of a hangover and needs immediate attention.

FAQ

1. Why do my hands shake the morning after drinking, even though I'm not an alcoholic?

This is because your central nervous system goes into overdrive to compensate for the chemical imbalance in your body. As alcohol leaves your body, the brain can become overstimulated. This causes it to send uncoordinated nerve signals to your muscles, resulting in shaking. Other factors, like dehydration and poor sleep, can also cause alcohol tremors.  

2. Can anxiety after drinking cause shaking?

Yes. Anxiety is a common side effect of hangovers and can result in shaking. This state is known as hangxiety and can entail panic attacks. It is caused by the body producing excessive glutamate to counter the effects of GABA neurotransmitters and restore neural balance. It’s better to consider taking vitamins pre-drinking as a prevention. 

3. Is shaking after drinking a common hangover symptom?

Yes, alcohol tremors are a common hangover symptom. It can occur alongside other symptoms such as headaches, nausea, fatigue, and dehydration. Fortunately, you can prepare for and mitigate these effects by taking UPSWING vitamin supplements before drinking.  

4. At what stage of alcoholism does one start to shake?

Alcohol related shaking typically occurs in heavy and regular drinkers. For occasional social drinkers, it is mild and appears several hours after drinking and improves quickly. For regular heavy drinkers, shaking can signal that the body has become physically dependent on alcohol. These tremors usually begin 6 to 12 hours after the last drink as the nervous system rebounds. The severity varies — some people experience mild shakes early on, while others may not notice them until drinking has escalated significant

5. Why do alcohol tremors get worse before they get better?

This is because the brain temporarily becomes more active as alcohol leaves your body. It causes a rebound effect that can intensify the tremors. Once your body stabilizes, the shaking effects also reduce accordingly.  

6. Can shaking after drinking alcohol cause permanent damage?

Mild shaking after a hangover usually doesn’t have any long-term effects. However, severe and persistent alcohol tremors can lead to Delirium Tremens, which is an acute medical condition.  If you're experiencing intense or lasting shakes, it's important to have a medical professional evaluate them to help stop symptoms and prevent any permanent damage.
