NEGATIVE EFFECTS OF CAFFIENE
Caffeine is a chemical found in coffee, tea, cola, guarana, mate, and other products. It is most commonly used to improve mental alertness, but it has many other uses. Caffeine works by stimulating the central nervous system (CNS), heart, muscles, and the centres that control blood pressure. Caffeine can also raise blood pressure. Studies have shown that it may become habit-forming as it riggers certain brain chemicals similarly to the way cocaine and amphetamines do.
But, how much caffeine should you intake? Is caffeine good for your health?
Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That’s about 4 cups a day. However, it still shouldn’t be taken for granted and had every day. This is because more than 4 cups every day has been linked to early death. Here are some more negative uses of caffeine:
- Caffeine is known to increase alertness. However, at higher doses, these effects may become more pronounced, leading to anxiety, jitteriness, restlessness, tremors and nervousness.
- Too much caffeine may also promote headaches, migraines and high blood pressure in some individuals
- Coffee may be your go to when you’re sleepy but wish to stay up because Caffeine in a person’s system at bedtime can mimic the symptoms of insomnia. Too much of caffeine will ruin your sleep.
- Caffeine can cause stomach upset, nausea and vomiting, increased heart and breathing rate. This is why it may not be good for people with heart diseases and may also result in a heart attack.
- Large doses of caffeine may lead to frequent urination, loose stools or even diarrhoea in some people.
