Drink tea to be energized? How is it that some people get more tired after drinking?

Tea is often used by us as a kind of "stimulant", to ward off drowsiness and fatigue. In the morning and after noon, we're in the habit of beginning to enter into our working state with a cup of tea. Tea sharpens one's mind, a key role being played by caffeine contained in the tea leaves and by small quantities of theine.

Caffeine has the effect of stimulating the nerves in the brain and promoting cardiovascular excitement, and even with the same weight as tea, caffeine is contained more than coffee.

However there are exceptions, some people find that after drinking a lot of tea, they actually become more and more tired, without the expected stimulating effect. What is going on here?

Physical constitution of individual

The stimulating effects of tea are variable from person to person.

Some people have an immunity to caffeine and drinking more tea won't make them feel more energized because the caffeine can't take effect on their bodies.

If you never experienced insomnia or alertness when first drinking tea, then you belong to this group.

2, Body gradually adapts.

Due to frequent drinking of tea, you are likely to have a resistance to tea, and the invigorating effect of tea is hard to be felt, just like having a strong resistance to alcohol after frequent drinking.

Tea intoxication phenomenon

Concentrated tea is supposed to be the most worthy of stimulating appliances in people's impression, and the more concentrated the tea, the more exciting. Drinking strong tea will indeed produce a strong stimulating effect on the nervous system, putting the brain into an overly excited state.

However, if the concentration of caffeine in concentrated tea is too high, it can inhibit the supply reaction of blood glucose in the intestine to a certain extent, causing insufficient blood glucose supply. The body may then experience symptoms similar to low blood sugar, such as dizziness and inability to concentrate. These are similar to feelings of fatigue when feeling drowsy.

Excessive physical exhaustion

The body itself is extremely tired and exhausted, these amounts of tea do not have enough energy to resist sleepiness.

Steeping tea for too long.

There is another factor that affects the amount of caffeine in tea, and that is brewing time. The longer you steep it, the more caffeine will be extracted from the leaves. When brewed for 2 minutes, the tea contains about 70-80% of its total caffeine content, making this the most stimulating brew.

The longer tea leaves are steeped, the more polyphenols will be present in the tea. This can counteract the caffeine's effect and greatly reduce its stimulating effect.

So you have to pay attention, if tea is brewed for too long, it will probably inhibit brain nerves excitement and actually work as sedative.

How can we drink tea in a way that is both invigorating and healthy?

Try different types of tea.

Try out different tea varieties to see which one has a better caffeine effect for you. Switching the taste of your tea can help reduce habituation and improve its energizing effects.

Adjust tea soup concentration appropriately

Based on your own tolerance, be careful not to over-consume strong tea as it may burden the heart and kidneys. If you feel dizzy or experience low blood sugar during drinking tea, eat a sweet dessert to replenish glucose and energy at once.

If it's really a long-term fatigue situation, drinking tea alone won't do. It's suggested that you take the time to rest and that your body is what everything is based on. Moreover, you should get some exercise to boost up your physical condition so as to keep your mental state in a better shape.
