Coffee is good, but the negative effects should be noted

        If you want the refreshing effect of coffee, but also reduce the negative effects, drinking time is very important! The half-life of caffeine in the human body is about 4-6 hours. If you don't want to be disturbed by caffeine, you can drink coffee earlier. For example, when you go to bed at 10 pm, you can extend it to 7 hours before going to bed without drinking coffee. That is, stop drinking after 3 pm.
        Since caffeine does not take effect until 20-30 minutes after drinking it, if you have a habit of taking a lunch break, you can take a nap immediately after drinking coffee first, and wake up just to play a boosting effect. In addition, under normal sleep conditions, the concentration of cortisol in the body is the highest when you just get up. At this time, the refreshing effect of coffee is not obvious. It is recommended to drink it 2-3 hours after getting up or 2-3 hours after lunch.
        Coffee not only has a strong aroma, but you can also drink it slowly, and you can also feel the rich taste level! However, coffee can also have negative effects! Caffeine can boost the spirit, but it can also easily stimulate the nervous center and increase the secretion of hormones such as adrenal cortisol. Excessive amounts may also lead to palpitations, anxiety, insomnia, and other conditions. Caffeine can also stimulate gastric acid secretion, which can make gastroesophageal reflux or gastric ulcer symptoms worse; if ingested in excess, it may even cause calcium loss and affect bone health.
        How much caffeine can you consume per day? Daily caffeine intake limits vary by age group.
        Adults: no more than 300 mg
        Pregnant women: no more than 200 mg
        Adolescents 12 to 18 years: should be within 100 mg
        Children under 12 years old: Avoid caffeine as it may affect growth.
        Learn to calculate your overall caffeine intake
        When purchasing packaged beverages containing caffeine, the actual caffeine content is often marked in mg/100 mL on the outer packaging of the product. Beverages with less than 20 mg of caffeine per 100 mL can be marked as less than 20 mg/100 ml. Those with less than 2 mg can be directly labeled as 'decaffeinated'. When purchasing, you can convert the total amount of caffeine you drink from the beverage volume and the caffeine content on the label to control your caffeine intake.
        Excessive caffeine will harm the human body. When purchasing drinks, you should pay attention to the caffeine content label and control the daily drinking amount to enjoy the delicious coffee without any burden.
