COVID-19 vaccines are now widely available. And so are the booster shots. If you are going for either, you should know that you need to prepare for what’s coming. Despite offering good protection from COVID-19 and its ever-changing variants, COVID-19 vaccines have minor side effects like pain at the injection site, fever, fatigue, or weakness. To reduce the side effects, you should consider having a proper meal and hydrating before going for the vaccine. Read on to know the detailed answer about should you drink water before a COVID-19 vaccine.
The Suggestion
Many pharmacies are suggesting people eat a healthy meal and hydrate before the COVID-19 vaccination as it might help in reducing any side effects. Some pharmacies suggest a person should drink at least sixteen ounces of water one hour before their appointment to prevent side effects.
Post Vaccination
CDC recommends that people who have got vaccinated should stay hydrated even after getting the vaccine, especially if they have a fever as a side effect. However, no specific amount of water was highlighted,
Fainting Incidents
In some cases, people fainted during or shortly after the administration of the COVID-19 vaccine. To prevent that, some pharmacies suggest drinking plenty of water. Hydrating might help increase intravascular volume and prevent a vasovagal syncope event which might lead to the fainting of an individual. Even CDC has highlighted fainting as a concern.
Even the CDC website says that the patients should be given a beverage, snack, and reassurance about the procedure to prevent fainting.
An expert stated that people are more likely to faint when dehydrated. Some experts also recommend that you will be less likely to feel woozy when you are better hydrated.
No Magic Prevention
Though drinking water can help make the side effects less bad, it doesn’t offer magic prevention from the side effects or doesn’t do much for your immune system’s enhancement. However, drinking water and keeping yourself hydrated will keep you feeling good in general and might make you feel better even if you develop any side effects.
Also, if you get a vaccine when you are dehydrated, the side effects will make you feel worse, and you will probably get more dehydrated. For instance, if you get a fever when you are dehydrated, it will make it worse. Also, dehydration can exacerbate a headache.
The Verdict
All in all, having some pure water before a COVID-19 vaccine cannot hurt but might help your body to deal with the side effects better. So, drink up!
