Drinking iced tea has been linked to a reduced risk of stroke, according to research. Tea is the second most consumed beverage in the world, after water, and is linked to a range of health benefits. Tea consumption has been associated with a reduced risk of hypertension, diabetes, and atherosclerosis, all of which are major risk factors for stroke.
However, it is important to note that excessive tea consumption may lead to negative side effects such as anxiety, poor sleep, and headaches due to its caffeine and tannin content.

Tea consumption is associated with a decreased risk of stroke, particularly ischemic stroke
Tea is the second most consumed beverage worldwide, after water. Tea consumption has been associated with a reduced risk of hypertension, diabetes, and atherosclerosis, all of which are major risk factors for stroke.
A 2012 meta-analysis of 14 prospective cohort studies found a significant inverse association between tea consumption and the risk of stroke, particularly ischemic stroke. The analysis included 513,804 participants with a median follow-up of 11.5 years and found that an increase of three cups of tea per day was associated with a 13% decreased risk of stroke and a 24% decreased risk of ischemic stroke. The relationship between tea consumption and reduced stroke risk persisted across most subgroups, including female participants, drinkers of green tea, and Japanese studies.
These findings suggest that tea consumption, especially green tea, may play a protective role against stroke, but more well-designed studies are needed to confirm these results and explore the underlying mechanisms.

Hypertension
Hypertension is the most dangerous factor linked to deaths caused by cardiovascular diseases. In a study conducted in China, the consumption of green tea was found to be inversely associated with five-year diastolic blood pressure but not systolic blood pressure. Another study showed that habitual moderate-strength green or oolong tea consumption of at least 120 mL/day for one year significantly reduces the risk of developing hypertension in the Chinese population. A meta-analysis of 13 randomised controlled trials found that consumption of green tea significantly reduced systolic blood pressure by 2.08 mmHg and diastolic blood pressure by 1.71 mmHg. A separate meta-analysis of prospective studies found that an increase of three cups/day in tea consumption was associated with a 13% decreased risk of stroke.
Diabetes
Diabetes is another major risk factor for strokes. A meta-analysis of nine cohort studies found that participants who drank four or more cups of tea per day had a 20% lower risk of type 2 diabetes compared with those who drank less or none. Another meta-analysis of 14 prospective cohort studies found that tea consumption was associated with a decreased risk of stroke, particularly ischemic stroke. A study conducted in Japan with 60 volunteers who had high fasting blood glucose levels found that supplementation of green tea extract powder led to a significant reduction in diastolic blood pressure, but no significant changes in systolic blood pressure.
Atherosclerosis
Atherosclerosis is a condition where plaque builds up inside the arteries, restricting blood flow. A study conducted in China found that tea consumption was associated with reduced risks of atherosclerotic cardiovascular disease and all-cause mortality, especially among those consistent habitual tea drinkers.

Tea contains polyphenols, which are thought to promote healthy blood vessels and dampen inflammation
The polyphenols in tea have been shown to have a wide range of beneficial effects on health. They have been found to reduce inflammation, which in turn may reduce the buildup of cholesterol-filled plaque inside arteries. Polyphenols can also improve vascular reactivity, a measure of how well blood vessels respond to physical or emotional stress. In addition, there is evidence that polyphenols can lower harmful LDL cholesterol levels.
Several large, population-based studies show that people who regularly drink black or green tea may be less likely to have heart attacks and strokes. However, more research is needed to confirm the relationship between tea consumption and reduced risk of stroke, as people who drink tea tend to be different from those who do not.

Green tea polyphenols have been linked to increased skin protection from UV rays and improved skin elasticity
Green tea polyphenols (GTPPs) have been linked to increased skin protection from UV rays and improved skin elasticity. GTPPs are naturally occurring chemicals derived from plants, fruits, nuts, and vegetables. They have been proven to have many beneficial health effects. GTPPs have been shown to have significant antioxidant, chemopreventive, and immunomodulatory effects in protecting the skin.
Ultraviolet radiation (UVR) is a major environmental source of skin damage and can lead to immunosuppression, oxidative stress, premature ageing, and tumour formation. The skin's biology and immune system are significantly impacted by UVR, which plays a crucial role in photoaging, inflammation, and carcinogenesis.
Human and animal studies have shown that GTPPs, when applied topically or consumed orally, provide significant protection against UV-induced skin damage and immunosuppression. Topical application of GTPPs has been shown to be more effective than oral consumption in providing photoprotection. In vivo studies in mice have shown that topical application of GTPPs significantly reduced UVB irradiation-induced depletion of antioxidant enzymes and signalling protein phosphorylation.
GTPPs have also been shown to reduce UVR-induced immunosuppression via a dose-dependent decrease in contact hypersensitivity response. Similar results have been observed in adult human subjects who ingested green tea, showing a significant decrease in UVR-induced DNA damage of peripheral white blood cells.
In addition, GTPPs have been found to improve skin elasticity and overall skin quality. A 12-week, double-blind, placebo-controlled study involving 60 female volunteers found that consumption of a beverage containing GTPPs resulted in a significant decrease in UV-induced erythema and positive effects on skin elasticity, roughness, scaling, density, and water homeostasis.
Overall, GTPPs have been shown to provide photoprotection, improve skin elasticity, and enhance overall skin quality, making them a promising candidate for skin protection and treatment.

Tea is a diuretic, which means it causes you to pass more urine and can result in dehydration if not properly hydrated
When you drink tea, your body absorbs as much fluid as it needs, and you will urinate to expel any excess. In short, tea can increase urine production but does not cause a net loss of fluids. A recent review of 16 studies reported that a dose of 300 mg of caffeine, or the equivalent of drinking 3 1/2 to 8 cups of tea at once, increases urine production by just 109 ml compared to the same amount of non-caffeinated drinks.
Furthermore, a study published in the British Journal of Nutrition found no difference in hydration levels between participants who drank only tea for 12 hours and those who drank the same amount of boiled water. This indicates that tea is just as hydrating as water when consumed in moderate amounts.
In summary, tea is a diuretic, but it does not lead to dehydration under average consumption. Research has shown that when consumed in moderate amounts, tea is just as hydrating as water. However, consuming large amounts of tea, such as between 5 and 15 cups per day, may have a mild diuretic effect, but it still wouldn't lead to dehydration in healthy individuals.

Frequently asked questions
Iced tea has many health benefits, including reducing the risk of heart disease, boosting the immune system, improving concentration, decreasing the risk of dementia, and helping with diabetes management. However, it's important to consume tea in moderation, as excessive intake may lead to side effects such as anxiety, poor sleep, and headaches due to its caffeine and tannin content.
Drinking iced tea can provide various mental and physical health benefits. It has been linked to a reduced risk of heart disease, improved immune function, better concentration, and lower chances of dementia and diabetes. Iced tea also contains antioxidants and anti-inflammatory compounds, which can promote a healthy gut and reduce the risk of certain cancers.
Research suggests that drinking two to three cups of tea per day can maximise the health benefits without overdoing the caffeine intake. However, it's important to monitor sugar intake, as pre-made iced tea drinks often contain high amounts of sugar.
Tea contains tannins, which can bind to iron in certain foods, making it unavailable for absorption in the digestive tract. If you have low iron levels, it is recommended to limit tea intake to three cups or fewer per day and consume tea between meals to minimise its impact on iron absorption.
Yes, drinking excessive amounts of tea can contribute to recurrent headaches. Caffeine withdrawal can also lead to headaches, irritability, increased heart rate, and fatigue. It is recommended to limit tea intake to three to four cups per day to avoid potential side effects.
