So, in winter, enjoy hot tea to keep your body warm. When drinking hot tea, your throat is also “steamed”, preventing flu and colds in the winter.

2.2. Health benefits of cold tea

Tea is a popular drink in Vietnam and around the world. Iced tea and lemon tea on the sidewalk are popular and “delicious, nutritious, and cheap” drinks, helping to cool down and have many health benefits in hot weather.

Here are the benefits of drinking cold tea (ice tea, lemon tea,…) to cool down on summer days:

Cold tea contains higher levels of active compounds

According to a study by Lantano et al. in 2015, cold tea helps optimize the beneficial properties of tea, such as significantly increased antioxidants, phenolic content and gallic acid concentrations. However, you still have to brew it hot to let the tea steep before adding ice or after the tea cools, put it in the refrigerator.

Cold tea has many advantages for heart health

Although some experts believe that iced tea contains more antioxidants due to the longer time spent steeping in water, more research is needed to prove it. The amount of antioxidants in different types of tea depends significantly on the tea leaf variety, cultivation method, production process, etc.

Cold tea contains lower caffeine content than hot tea

Researcher Claire M and colleagues in 2018 found that decaffeinated herbal tea consumed at cool temperatures had superior benefits for heart health compared to hot tea.

Cold temperatures are thought to promote higher metabolic activity and fatty acid oxidation, contributing to overall cardiovascular health. These effects may be beneficial for people who cannot use thermogenic drugs due to obesity, hypertension, or other heart problems. However, according to the researchers, more research is needed to confirm the effectiveness of decaffeinated cold tea for weight loss.

Cold tea contains lower levels of caffeine

According to research, a cup of black tea contains about 25-48 mg of caffeine, and a cup of green tea contains about 25-29 mg of caffeine.

If you’re trying to cut back on caffeine, according to research by Lin et al. In 2014, cold tea will help you do that. Drinking iced tea or cool tea will reduce the amount of caffeine absorbed into the body from tea. This is something that will appeal to many people in the summer when they want to enjoy a cool glass of lemon tea or iced tea (black tea, green tea,…) without having to worry too much about the side effects of caffeine.

However, when drinking cool tea to cool down in the summer, you should also pay attention to the amount of sugar in your body. In addition, when drinking hot or cool tea, you can also add herbs to enhance the flavor such as fresh mint leaves in summer or a cinnamon stick in winter.
