Caffeine has positive effects on improving short-term and long-term memory
Coffee comes from western countries. In the United States, research shows that 80% of adults consume caffeine every day. Nowadays, coffee is also a popular drink in the eyes of Chinese people. You or your friends and family may also drink coffee every day. But I think your understanding of caffeine is only superficial. For example, caffeine is found in coffee drinks and sodas. It can stimulate your energy, in fact, in addition to these, there are many secrets about caffeine, let's learn about it with the editor:
1. Caffeine has a positive effect on improving short-term and long-term memory. In the past, a large number of studies have shown that caffeine has a positive effect on short-term memory, and recent studies have also shown that caffeine has a positive effect on long-term memory. "consuming 300 milligrams and 400 milligrams of caffeine a day can prevent cognitive decline and Alzheimer's syndrome." "getting enough sleep is also important to prevent Alzheimer's syndrome, so keep that in mind if you're allergic to caffeine," said Jaclyn London, a senior dietitian at Mount Sinai Hospital in New York City.
two。 Caffeine can improve sports performance. Taking in the right amount of caffeine about an hour before fitness or competition can improve your exercise performance. "Statistics show that caffeine has a great effect on increasing alertness and shortening reaction time." "what's more interesting is that caffeine lowers your perception of effort," says London. In other words, after consuming the right amount of caffeine, you will put more effort into the same amount of work.
3. The effect of caffeine on the human body is almost immediate. Caffeine can easily cross the blood-brain barrier, so the central nervous system is stimulated quickly, which means you feel more alert and affected immediately after consuming caffeine. until the effect reaches its peak (30-60 minutes after caffeine intake).
4. Caffeine content varies from coffee to coffee. A study published in the journal Analytical Toxicology shows that Starbucks'16 ounces of coffee contains 100mg more caffeine than the same cup of coffee from Dunkin' Donuts. The study also found that caffeine levels in the same drink from the same chain may vary from day to day, with a difference of up to 300mg. A standard cup of coffee contains about 90,225 milligrams of caffeine, London said.
5. Caffeine won't dehydrate you. Since 98% of caffeine is consumed in drinks, according to FDA, you are hydrating while you consume caffeine. So although caffeine is a diuretic, it doesn't dehydrate you. However, this does not mean that you can only drink caffeinated drinks; enjoy coffee drinks in moderation, and don't forget that water is still the best drink for hydration.
6. The source of caffeine is not just a variety of drinks. Chocolate is also one of the main sources of caffeine, and caffeine can be added to almost all kinds of foods or substitutes, which is why you can always find caffeine in drugs such as Midol. So, if you have heart disease or high blood pressure, be sure to consult your doctor when taking any caffeinated analgesics.
