What causes a hangover feeling without drinking?
Feeling the symptoms of a hangover without drinking is a sign from your body that something is not quite right.
Now, it's important for us to emphasize that the list of medical conditions that could micic a hangover are endless. That's why you should always consult your doctor if you're not feeling well.
With that said, here are some of the most common reasons why people feel like they're hungover without having any alcohol:
Dehydration
Dehydration is one of the main causes of a hangover. It causes symptoms such as feeling light-headed, inability to think straight and dry mouth.
You don’t have to drink to be dehydrated of course. If you’ve been doing a lot of exercise lately, travelling or been over-exerting yourself at work, you can often forget to drink enough water. Find out how to quickly rehydrate your body if you're feeling dehydrated.
Electrolyte imbalances
Excessive sweating from exercise or hot weather can cause electrolyte imbalances, leading to mental and physical symptoms similar to a hangover. Replenishing your electrolytes through hydration and proper nutrition is essential to avoid these symptoms.
Caffeine withdrawal
If you’re like many of us and have an unhealthy relationship with caffeine, abrupt abstinence from having any can make you feel rough.
The symptoms of caffeine withdrawal include headache, agitation, and inability to concentrate which are very similar to the key symptoms of a hangover.
Excessive caffeine intake can cause hangover-like symptoms, too, including dehydration and anxiety.
Underlying medical condition
If you’re feeling hungover without drinking alcohol for a prolonged period of time, it may be due to an underlying undiagnosed medical condition.
Common conditions include anemia, hypothyroidism (low thyroid) and diabetes. These can all make you feel without energy, sleepy and not your usual self. For example, a condition called pernicious anemia is especially common in people with vitamin B12 deficiencies and can cause chronic fatigue and weakness, mirroring hangover symptoms.
There are more serious medical conditions that could also present this way which is beyond the scope of this article. The most important takeaway point is that you should see your doctor for a health check if you’re not feeling well.
Medication
As we get older, the chances of us being on medication increases and so do the side-effects that come with it. Certain medications can make you feel you have brain fog and a lack of energy.
The most common include benzodiazepines (colloquially called “sleeping tablets”), beta-blockers and antidepressants. However, there are many more that could make you feel this way. Over-the-counter sleep aids and supplements like melatonin can also cause morning grogginess and headaches.
If you're not feeling great after you've recently started a new medication or a dose change, it's essential you check in with your physician.
Infection
If you wake up feeling hungover without having had any alcohol, you may be coming down with an infection. People can often feel feverish and sweaty after a big night out which can be confused with a hangover. It's becuase alcohol is known to dysregulate your internal thermostat, so it can mimic the early stages of a hangover.
But common viral and bacterial infections such as the flu can masquerade as a hangover in the beginning stages. That's why if you have been on a night out and you can't seem to shake off your 2 day hangover, something else is probably going on. You may even find that a delayed hangover can occur up to 24 hours after your last drink, presenting the same hangover symptoms that you expected when you first woke up after the night out.
Mood
Low mood and anxiety are often overlooked causes of “hangover type” symptoms. Low energy, lack of interest and anxiety can all be associated with a hangover.
If you have these feelings for more than a few days, it’s always best to see your doctor to get checked out.
Migraines
The aftermath of a migraine, called the “postdrome,” can leave you feeling exhausted and cause lingering headaches, similar to a hangover. If you suffer from migraines, it’s important to recognize this phase and manage it with advice from your doctor.
Sleep issues
It's becoming clearer nowadays that sleep has a huge impact on our overall health. Not getting enough high quality sleep has been shown to increase the risk of infection, cardiovascular disease, diabetes and even cancer!
Sleep is an often neglected aspect of our general health and it may be time to make some changes if you know you are not getting enough it.
Sugar
Eating too much sugar can lead to blood sugar spikes and crashes, disrupting your sleep and causing headaches, shakiness, and fatigue the next day. But monitoring your sugar intake can help avoid these unpleasant symptoms.
Electrolyte imbalances
Believe it or not, pregnancy can cause hangover-like symptoms without drinking any alcohol. There are countless cases of women going to see their doctor feeling run down, with no energy and nauseous to find out they are actually pregnant!
In fact, it’s so common that most emergency departments do pregnancy tests on women of childbearing age who present feeling unwell.
Furthermore, during the first trimester of pregnancy, hormonal and physiological changes cause blood pressure to drop. In addition, circulating blood volume increases which causes “physiological anemia” from dilution.
As a result, pregnant women commonly feel more tired than usual which can mimic having a hangover without drinking.

Middle and inner ear problems such as labyrinthitis and benign positional vertigo can make you to feel dizzy and unsteady. It can also be a sign of very serious underlying medical conditions like a cerebellar stroke.
