Tea plays a prominent role in British culture. According to statistics, approximately 165 million cups of tea are consumed daily in the United Kingdom, while coffee, the second most popular drink, follows with 95 million cups a day. Often, we choose our drink based on how it affects us: tea can be soothing, while coffee keeps us awake. But is there any scientific basis for why we choose coffee or tea, aside from personal taste?

Caffeine, a key ingredient in both drinks, occurs in varying amounts depending on the type of coffee or tea we prepare. Coffee generally contains more caffeine than tea. As a result, coffee provides a stronger sense of alertness and can wake us up faster. However, as some research has shown, the effects aren’t always as simple as they seem.

The caffeine content in an average cup of coffee ranges from 40 to 300 milligrams. Stronger coffee varieties contain more caffeine, while weaker ones have less. Research shows that coffee improves alertness, enhances concentration, and speeds up reaction time. However, its effects on memory, judgment, and decision-making are more mixed and not always consistent.

Tea contains less caffeine, but studies show that it also contains a special amino acid that enhances the effect of caffeine. This amino acid, in combination with caffeine, can improve concentration and help maintain attention for longer periods. So, if we feel that tea is a better choice for staying alert, we’re probably not mistaken.

But which drink is the better choice for health? According to scientific findings, both drinks—when consumed in moderation—can have positive effects on our health. Both tea and coffee are rich in polyphenols, plant-based compounds with various health benefits. Research has also shown that both drinks can help reduce the risk of developing type 2 diabetes. However, with coffee consumption, it is important to note that drinking more than four cups a day can increase blood pressure, so it’s wise to moderate daily caffeine intake.

It’s also important to ensure proper hydration when consuming caffeinated drinks. Since caffeine has a diuretic effect, excessive consumption can lead to dehydration, so it’s a good idea to increase daily water intake.

For those sensitive to caffeine, experiencing side effects like anxiety, sleep disturbances, or digestive issues, it’s advisable to choose tea or switch to decaffeinated drinks. Decaffeinated alternatives can help avoid unwanted side effects while still allowing us to enjoy our favorite beverages.

Gradual caffeine withdrawal can also be important for those looking to eliminate caffeine consumption. Sudden withdrawal can lead to severe symptoms, which are more pronounced if we’ve consumed caffeine in larger amounts, such as coffee. Tea drinkers generally experience milder withdrawal symptoms, but the process should still be done gradually.

For pregnant women, the NHS recommends limiting caffeine intake, and caffeinated drinks are also not recommended for young children.

In conclusion, both tea and coffee have their benefits, but it’s important to consider our health, sensitivities, and the appropriate amount we consume.
