Допоможіть! Це рідінг If your heart starts beating quickly after you've had a can of cola or other fizzy drink, then you should listen carefully to what your body's trying to tell you. Many fizzy drinks contain caffeine, like coffee does, and this is what wakes you up and gives you energy. It can also make you breathe more quickly and even affect your sleep, as well as raise your blood pressure, which could put you at risk of a heart attack or other medical condition.

If you notice effects like these which feel unpleasant. of you think that your heart is often beating Inn fast, it might be time to cut down on the number of fizzy drinks you're having You don't have to stop drinking them altogether, but it's definitely a good idea to drink more water during the day than other kinds of drink, including coffee, tea or hot chocolate, which also contain caffeine And you should avoid having any of these drinks at least six hours before you want to go to sleep However, if you already drink a lot of caffeine, don't stop suddenly, Doing so can cause headaches, stop you being able to concentrate and make you feel more anxious than usual.
Some studies suggest that you should include some caffeine in your diet because it helps to reduce the possibility of heart problems and developing some kinds of cancer. It can also help you keep going while you exercise and reduce muscle pain after you've worked out. And, of course, it is helpful when you want to stay awake and study when you start yawning!

But how much caffeine in healthy? Doctors say that teenagers shouldn't have more than 100 mg a day, which is about one cup of coffee, or about three cans of regular cola. That isn't to say that drinking three cans of cola is good for you, it contains a lot of sugar and can cause the negative effects mentioned earlier. You should also be very careful with energy drinks. Some large cans can contain over 150 mg of caffeine, which is more than the recommended daily amount for a teenager.
Remember if your heart often beats fast when you're resting and you don't have fizzy drinks or other drinks containing caffeine, you could have a medical problem. So, if you're even a little bit worried, you should go and ask the doctor to check you over.
