Two Common sense about Coffee and Human body Coffee and Health

The "Journey" after Coffee enters the Human body

Coffee is fragrant and refreshing, but do you know what chemical changes will take place in the human body after a cup of coffee? Recently, a foreign website described in detail the "journey" of coffee into the human body, which is very interesting.

Ten minutes after drinking the coffee: caffeine enters the bloodstream and the heartbeat and blood pressure begin to rise. Caffeine can alleviate the effect of alcohol on the human body, and the effective time is 10-90 minutes.

20 minutes after drinking coffee: the brain becomes active, concentration increases, and problem solving becomes easier, and this benign effect will last for 10 minutes.

30 minutes after drinking coffee: improved exercise ability, serotonin will stimulate nerve cell activity, making muscle activity more effective. At the same time, the secretion of epinephrine increases, which can excite the body and inhibit fatigue.

Four hours after drinking coffee: fat begins to burn. Consuming 50 milligrams of caffeine, even if you sit still, will increase calorie consumption.

Six hours after drinking coffee: the whole person relaxes physically and mentally and feels comfortable and satisfied.

The effective time of caffeine is 2-12 hours: depending on age and sensitivity to caffeine, the exciting awakening effect of caffeine will disappear in about 2-12 hours, and the whole person will return to normal.

Why is it better to smell coffee than to drink it?

Why do we feel that it doesn't smell good when we drink coffee? Barry, a professor at University of London. The conclusion of Smith's study is that we have two senses about smell, one of which is caused by inhalation in the external environment. The other is when the smell is exhaled out through your nasal cavity. The act of swallowing coffee sends an aroma from the inside of the mouth to the nasal cavity, stimulating the brain to produce a "secondary sense of smell." This time the feeling is not as strong as it was when I first smelled it, giving people a completely different, less satisfying feeling. Although we have taste buds on our tongues, 80% of the taste we taste is actually sensed through the olfactory receptors in the nasal cavity, while these receptors that send messages to the brain feel differently about the smell that moves in different directions. Another reason why it doesn't smell good is that 300 of the 631 chemicals that make up the taste of coffee are killed by saliva, causing it to change before we swallow it.
