Health Benefits of Tea: Should You Drink It Every Day?
How Green Tea, Black Tea and Herbal Tea Support Health and What To Consider
Published May 2026
After water, tea is one of the most consumed beverages in the world, enjoyed across cultures and generations. From a morning cup of green tea to a calming mug of chamomile at night, drinking tea is often tied to comfort and routine.
Beyond taste, tea has also long been connected to wellness. Research continues to explore the many health benefits of tea, including its potential role in overall well‑being.
Understanding the different types of tea, where they come from and what makes each one unique can make it easier to choose options that fit your preferences and daily routine.

Where Tea Comes From
Most traditional teas come from the Camellia sinensis plant. What makes each tea different is how the tea leaves are processed after they’re harvested. These steps affect both the flavor and the color of the tea.
Different processing methods, such as oxidation and drying, create the familiar varieties:
- Green tea: Lightly processed to keep a fresh, grassy flavor
- Black tea: Processed more than other teas, giving it a darker color and stronger taste
- White tea: Minimally processed for a lighter, more delicate flavor
In contrast, herbal tea is not made from the tea plant. Instead, it’s created from dried herbs, flowers, spices or roots, such as chamomile, ginger, cinnamon and dandelion. Because of this, herbal tea is naturally caffeine‑free.
Health Benefits of Drinking Tea
Tea has been widely studied for its potential role in supporting health.Research shows that tea contains antioxidants and plant compounds that may help protect cells from everyday stress and reduce inflammation. This is why tea is often described as having anti-inflammatory effects.
Some studies also suggest that drinking tea regularly may be linked to reduced risks of certain medical conditions, including cognitive decline and heart disease.
Drinking tea isn’t a replacement for medical care, but it can be a simple, everyday habit that supports long‑term well-being.
Benefits of Different Types of Tea
Green tea
Green tea is one of the most studied types of tea when it comes to health benefits. It contains antioxidants that may support heart health, brain function and metabolism. Matcha, a finely powdered green tea made from whole leaves, contains similar compounds in a more concentrated form.Black tea
Black tea can support heart health and alertness. It contains more caffeine than green tea but less than coffee, which may provide a more balanced energy boost.
An 8-ounce cup of black tea has about 40 to 90 milligrams of caffeine, compared with 20 to 50 milligrams in green tea and about 95 milligrams in coffee.
Because black tea contains caffeine, it can interfere with sleep or cause restlessness, especially if you drink it later in the day.
White tea
White tea is lightly processed and contains antioxidants similar to green tea, though less research is available. It is often chosen for its mild flavor.- Chamomile tea may help promote relaxation and sleep.
- Ginger tea and peppermint tea may help with digestion and nausea.
- Cinnamon tea may support blood sugar balance.
- Dandelion tea is often used to support digestion.
Herbal tea
The benefits of drinking herbal tea depend on the ingredients:
Because herbal teas are caffeine‑free, they are often a good choice as part of your bedtime routine.
“While there isn’t enough data to confirm these teas are a solution for stress relief or better sleep, some popular teas, such as chamomile and lavender, may help with stress and sleep,” says Laura E. Wargo, RD, a registered dietitian at Northwestern Medicine.
How Much Tea Should You Drink?
Tea can support your hydration goals and count toward your daily fluid intake. Even caffeinated teas can help keep you hydrated when you drink them in moderation.For most adults, drinking one to four cups of tea per day is the recommended range. This allows you to enjoy the potential benefits of tea without consuming too much caffeine.
Are There Risks to Drinking Too Much Tea?
“To achieve some of the health benefits linked to tea, such as a lower risk of stroke and Type 2 diabetes, it would require drinking fairly large amounts of tea regularly,” says Wargo. “Previous research shows that drinking a large amount of some teas may increase exposure to trace amounts of metals, such as lead, aluminum, arsenic and cadmium.”
At the same time, a 2025 Northwestern University study found that brewing tea may help reduce exposure to certain heavy metals. Tea leaves can absorb small amounts of these contaminants during steeping, and longer steeping times can increase this effect.
Some herbal teas, such as St. John’s wort, chamomile and ginkgo biloba, may also contain active ingredients that can interact with medications. These interactions can affect how the medications are absorbed, metabolized or how effectively they work. If you take medications, talk with your doctor before drinking herbal teas.
How To Choose Your Tea for Maximum Benefits
When choosing tea, a few simple tips can help you get the most benefit:
- Look for simple ingredient lists.
- Choose loose‑leaf tea or basic tea bags when possible.
- Limit bottled teas, which often contain added sugars.
- Check the amount of caffeine, especially if you’re sensitive to it.
- Follow recommended brewing times and temperatures to maximize flavor and antioxidant content.
Brewing tea at home can make it easier to have more oversight of the flavor, strength and ingredients.
Being mindful of how much caffeine and added sugar you consume throughout the day can also be helpful. The U.S. Food and Drug Administration (FDA) recommends limiting caffeine to about 400 milligrams per day — roughly the amount in two to three 12‑ounce cups of coffee.
Added sugar can add up quickly, especially in sweetened or bottled teas. The American Heart Association recommends keeping added sugars to no more than 6% of calories per day, which is about 6 teaspoons (25 grams) per day for women and 9 teaspoons (36 grams) per day for men.
Making Tea Part of Daily Life
Tea doesn’t have to replace other drinks — it can simply become part of your daily routine. Try green tea in the morning, black tea in the afternoon and herbal tea in the evening.
Over time, matching different teas to different parts of your day can support hydration and help build a routine that feels easy to maintain.
