Coffee common sense no coffee after 4: 00?
Many people like to stay awake through cup after cup of coffee at work, or have a cup of coffee at tea time. However, researchers at the Harvard School of Public Health in the United States suggest that it is best not to drink coffee after 4 p.m.
Studies have found that caffeine stimulates the central nervous system, heart and respiratory system. Appropriate amount of caffeine can reduce muscle fatigue and promote digestive juice secretion. It also promotes kidney function and is diuretic, but eating too much can lead to caffeine poisoning. Compared with other caffeinated drinks, such as soda and tea, coffee contains more caffeine and has a more significant effect on mood. 80% of the caffeine in coffee can be consumed by the human body.
There are about 140 milligrams of caffeine in a cup of coffee and only about 47 milligrams in a cup of tea. Drinking more than 480 milliliters of coffee or caffeinated drinks a day may cause headaches, tremors, anxiety, heart palpitations, and so on.
Getting seven to eight hours of sleep a day goes a long way to keeping you at work during the day. However, since it takes 8 to 10 hours to process caffeine, drinking coffee after 04:30 does more harm than good.
