Drink tea with cold water when insomnia

Since ancient times, people have been accustomed to hot water to convert tea, and believe that hot water can make the taste of tea and catechins, minerals and other beneficial foam.

In fact, the effect of cold water making tea is not bad at all. As long as you have enough patience and the fragrance of tea, the nutrition will slowly leak out.

Just as a Xiangxi folk song sang: “Cold water is slowly thickening.”.

Office workers, drivers, climbers, etc., no matter where you go, as long as you can buy mineral water, you can enjoy the “cold tea” of good health and care anytime, anywhere.

銆€銆€On the weekend night, the reporter tried to make a cup of tea with cold water and made a comparison with the hot water.

The reporter took out two identical glasses, added 3 grams of Xinyang Maojian, and then each exchanged 150 ml of water, only one cup was filled with hot water that had just been boiled, and the other cup was mixed with normal temperature mineral water.
The cup of tea that had just been poured into hot water was immediately fragrant and had a bitter taste.

The cup of tea poured into the mineral spring water, close to the glass can smell a touch of tea, a bite, feeling just a little more tea than mineral water.

After an hour of storage, drink a few more mouthfuls. The tea taste is already thicker, but the tea is hot, but the taste is not strong. After a few minutes, there is still tea in the mouth.

Later, with the mineral spring water refilled, the tea tastes a little lighter, but the cup “cold tea” is still delicious.

What made the reporter even more surprised was that after a few cups of “cold tea”, the reporter did not sleep at night as usual, but went to sleep in the middle of the night.

銆€銆€How is this going?

The next day, the reporter checked the information, and the experts found that the caffeine in the tea has a refreshing effect, which is why many people drink tea for insomnia, and the great advantage of cold water tea is that it can reduce the leaching of caffeine in tea.Avoid people losing sleep.

銆€銆€Some people have experimented with brewing tea with water at different temperatures. The amount of caffeine in the tea leaves decreases with the decrease of water temperature.

Among them, the amount of caffeine escaping from the tea brewed with water at 100 掳 C was about 1 for brewing tea leaves with water at 4 掳 C.

35 times.

銆€銆€It can be seen that people who have the desire to drink tea but have concerns about the irritancy of caffeine may wish to drink “cold tea”, in addition to preventing insomnia, and avoiding excessive coffee, which leads to rapid heartbeat, calcium loss and other probabilities.銆?銆€銆€Although the amount of caffeine leaching in cold water is less, does this mean that the amount of leaching that is beneficial to the human body such as catechins will also decrease?

the answer is negative.

Cold water tea is slowly thick, as long as you have enough patience, drink “cold tea” can also drink good nutrition.

Studies have shown that after 2 hours of cold water brewing, the amount of residual acid, free catechins and other similar components in the tea will exceed the amount of hot water soaked tea, while the cold water soaked tea for 8 hours, the insoluble water ester typeThe amount of catechins and other ingredients can be leached to about 70% of the hot water.

銆€銆€In addition, the study found that tea contains a polysaccharide that both promotes islet function and removes excess sugar from the blood.

However, this polysaccharide is afraid of heat. If hot water is brewed, it will be seriously damaged, and cold water soaking tea will avoid this problem.

From this point of view, drinking “cold tea” helps people control their blood sugar.

銆€銆€Although cold water tea has many benefits, not every tea is suitable for making “cold tea”.

Experts pointed out that the longer the fermentation time, the higher the phosphorus content in tea, and the cold tea should try to choose low-fermented tea instead of phosphorus.

In terms of the most common teas, green tea is more fermented, followed by oolong tea, and black tea, Tieguanyin and Pu’er tea are the higher fermentation levels.
