Can Tea Cause Headaches and Other Side Effects

Tea and Headaches

Tea contains caffeine. And caffeine can provide relief for a headache.

During a headache, your blood vessels tighten, swell, or g through other changes which cause an increase in blood flow around your brain. This blood flow increase causes pressure on the surrounding nerves which send pain messages to your brain and what’s bring the headache.

With its vasoconstrictive properties, caffeine can narrow down blood vessels to restrict blood flow and alleviate pain, providing headache relief.

However, as with anything, consuming too much tea means an increased caffeine intake and causes just the opposite.

When caffeine is consumed regularly, your body becomes dependent on its effect. So, as caffeine narrows your blood vessels, once you stopped drinking team, the blood vessels enlarge and expand which can trigger pain.

Tea Ingredients Trigger Migraine

Tea also has some specific ingredients that are linked to causing migraines. Teas with ingredients such as ginseng, ginkgo Biloba, and St. John’s wort has been shown to trigger or worsen migraines in small studies.

These herbs can interfere with the metabolism of some migraine medicines and make them less effective. In simpler terms, if you take an OTC medication to cure your headache and brewed yourself a warm-up of tea with one of those herbal ingredients thinking that it can help too, it could actually backfire.

Tea May Cause Histamine Reaction

Some tea herbs can also cause a histamine reaction in the body, which can result in a headache. A histamine reaction is a natural, inflammatory response from your immune system, triggered by an allergen. However, when chronically triggered or overly severe, a histamine reaction can cause headaches, migraines, and rashes.

To prevent this, you need to reduce the consumption of high-histamine foods, including herbs and teas with citrus flavors. Instead, you should consider drinking low-histamine teas like:

  • Rooibos tea
  • Peppermint tea
  • Chamomile tea
  • Hibiscus tea
  • Moringa tea
  • Nettle leaf tea
  • Dandelion root tea
