How to Use Caffeine: Benefits, Dose, and More

It is the very most popular medicine in the entire world. Coffee, tea, chocolate, guarana, sodas and some medicines all consist of caffeine. Some medicines contain caffeine to give you a “boost” while suffering the cold or flu symptoms. It helps make you feel better.

Uses

Caffeine can easily affect most of the body – it stimulates the brain and increases alertness; it triggers insomnia, headache, nervousness and dizziness; it releases adrenaline, the stress hormone; it raises heart rate and blood pressure; it increases the rate of breathing; it is a laxative and a fairly strong diuretic; it raises blood sugar levels.

It can work within 15 minutes of taking it and the influences can last for more than six hours.

Caffeine slows the absorption of minerals from food and flushes out the B vitamins.

Dose

An 8 oz cup of instant coffee has around 100 mg of caffeine, a cappuccino has something like 50 mg and decaf has just about 5 mg.

Moderation is the key, a 100 mg caffeine intake a day should present no problems, but very high amounts of 900 mg a day and more will cause addiction.

Safety

Caffeine can be addictive if enjoyed large amounts. Then more is needed for the same effect, and if you stop instantly, there are withdrawal symptoms to contend with.

Withdrawal symptoms include headache, depression, irritability, tiredness, nausea, and vomiting. Slow-moving reduction is the best way to stop.

Students who take caffeine to keep awake while studying are fooling themselves. It actually makes the memory worse, not actually better.
