Nutritionists say that long-term coffee drinkers are at risk of experiencing withdrawal symptoms if they suddenly stop using it. It is advisable to switch to tea or half black tea and half coffee and gradually reduce the amount, and pay attention to the upper limit of daily caffeine intake and drinking time.
Many office workers are addicted to drinking it every daycoffee The refreshing thing is that if you do not drink even for a day, you will have headache, drowsiness, fatigue and lack of concentration, which will affect work efficiency. Xu Huiyu, a nutritionist at the Tung Foundation Food Nutrition Center, said that if you feel that your excessive dependence on caffeine is affecting your life, you can first replace coffee with tea, or drink half black tea and half coffee to enjoy the caffeine, while gradually reducing caffeine intake.
Xu Huiyu said that caffeine stimulates sympathetic nerves, makes people feel energetic, promotes adrenaline secretion and accelerates the heartbeat. People who are addicted to caffeine for a long time may suffer from lack of energy, drowsiness, fatigue, difficulty concentrating and other withdrawal symptoms due to the lack of familiar stimulation if they suddenly stop taking it. Some people may also suffer from headache.
If you want to reduce your caffeine intake, Xue Huiyu recommends suddenly quitting drinking coffee every day and not drinking it at all, which can lead to a lack of energy at work. You can first start drinking tea, which has less caffeine than coffee. Green tea, in particular, contains high levels of catechins and theanine, which have a calming effect on the nerves.
If some people usually drink a lot of coffee and feel that the caffeine is too low when drinking tea, they can drink half black tea and half coffee first. They will still experience the same coffee taste visually and gustatoryly, but with less caffeine than before. If some people like the taste of coffee, they can also drink decaffeinated coffee.
Xue Huiyu pointed out that after gradually reducing caffeine, it takes about two weeks of completely avoiding caffeine before symptoms such as drowsiness and lack of concentration improve.
As for what amount of caffeine is considered excessive, Hui Huiyu pointed out that it is generally recommended not to consume more than 300 mg of caffeine a day, and you should aim for about 4 cups or more of coffee. Excessive consumption can cause rapid heartbeat, cold sweat, dizziness and even hand tremors. Apart from this, the timing of caffeine consumption is also very important. To avoid affecting sleep, it is advised to drink it half a day after waking up and stop drinking it half a day before going to bed.
