However, some people feel very thirsty after receiving a COVID booster or shot. This is not considered a side effect.

Spending the hours after you get your COVID-19 booster dose feeling like you can’t gulp down enough water? It’s not just you: The internet is full of anecdotes from people saying their boosters — and their initial COVID doses, in some cases — left them feeling parched.

So, what’s the deal? Here’s what you need to know.

First of all, COVID vaccines do not cause thirst.

Pain, redness and swelling around the injection site are some of the most frequent side effects. There is also possible fatigue, muscle pain, nausea, chills fever, or tiredness. according to the Centers for Disease Control and Prevention. That includes booster doses, too.

It’s worth noting that many experts are reluctant to even call those mild to moderate responses “side effects.” Really, they’re just “expected symptoms when our immune system is ramping up and doing its job,” explained Natasha Bhuyan, a physician at primary care practice One Medical. (That’s in contrast to serious but rare side effectsThis can happen.

Bhuyan said she hasn’t had any patients who have experienced thirst after their shots. That doesn’t mean it’s not happening, however. Millions of people have gotten vaccinated against COVID-19 over the past year, and there have been scores of anecdotes about side effects not yet confirmed, or even explored in studies — some much more credible than others.

“People have different symptoms when they get their immunizations, but I have heard of people feeling a little bit thirsty. That’s not an uncommon finding,” said LaTasha Perkins, a family physician in Washington, D.C.

There are several theories about why people may feel dry after receiving a booster.

After getting boosted, there are many reasons that someone may feel thirsty. Nerves are one reason. “If someone is nervous about the vaccine, that can cause dry mouth, as anxiety is linked to dry mouth,” Bhuyan said.

Then there’s the really obvious possibility, Bhuyan said: that people who were already dehydrated might feel particularly parched after getting a shot. They might just notice it more because they’re paying closer attention to how they’re feeling in general.

Other physiologic reasons are possible, however. One possibility is that a fever can lead to dehydration. That’s not specific to COVID vaccines; that risk is always thereAs your body begins to lose fluids and salt,

Your immune system may be working overtime, so you might feel thirsty.

“Every human is about 70% water, and a lot of that is in the vessels in your blood,” Perkins explained. If your immune system is activated, your body will ask a lot about your tonsils and adenoids.

“When you get the booster, it can definitely make your lymph nodes and your adenoids activate, which could make you feel a little bit thirsty,” Perkins said. “But it doesn’t mean anything’s wrong.”

Self-care before and after a baby is important.

If you haven’t already gotten boosted, do what you can to take care of yourself beforehand. Eat a nutritious meal. (If you’re looking for specifics, here are some good options.) To the extent it’s possible, avoid over-the-counter medicines like ibuprofen and aspirin beforehand, because it’s not clear whether they could impact how the vaccines work.

(You can tell if you’re in the general ballpark if you’re peeing every hour or two, or your urine is relatively clear, Perkins said.)

Bhuyan stated that patients should be well hydrated prior to going in for their vaccines. This is because any symptoms, such as headaches, could worsen if they are not properly hydrated.

Keep in mind that your immune system will do its job and you may feel a little sluggish after taking your booster. You can find the following: CDC says reactions to boosters have been basically the same as to the initial doses of either of the two mRNA vaccines or the Johnson & Johnson shot. But alas, there’s no accurate way to say whether your response will be better or worse than it was the first time around.

“Some people have zero symptoms other than their arm being sore. Others feel sluggish or tired, or they mount a fever,” Perkins said. “But keep in mind: It’s only your immune system responding.”
