Copopobia – the fear of fatigue, which we seem to succumb to, and therefore not only start the day with a coffee 😉 The best weapon against fatigue is the caffeine to which I now turn my attention:
- It is a component of coffee, tea, mate, guaraná, kola nut and in small quantities also of cocoa.
- In 1820 the pharmacist and chemist Runge succeeded in isolating pure caffeine from the coffee beans for the first time and can thus be regarded as the discoverer.
- Chemically: C8H10N4O2 – a substance from the group of stimulants.
- Pure caffeine is a white, odorless, crystalline powder with a bitter taste.
- More than 1000 ingredients: Besides caffeine, carbohydrates, proteins, fats, minerals and even vitamins are present in the bean.
- Roasted coffee beans contain depending on the species and variety 1,3-2% caffeine – Arabica less than Robusta.
- A cup of coffee (150 ml) contains about 40 to 120 mg of caffeine,
- A cup of espresso (30 ml) about 40 mg.
The dose makes the difference.
- In lower concentrations attention and concentration are increased, the learning process is facilitated and the long-term memory is improved, fatigue symptoms are eliminated and the peristalsis of the intestine is stimulated.
- Too high doses can cause caffeine nervousness, sleep disorders, headaches, gastrointestinal discomfort, loss of fine motor skills. All reasons why children should leave their fingers off.
- From > 1 g even excitation phenomena and a strongly accelerated pulse occur.
- In case of poisoning, anxiety or circulatory collapse may occur.
- Caffeine can also become chronically dependent. Caffeinism causes mental disorders with symptoms such as restlessness, agitation, mental changes, urge to urinate, and insomnia.
- Drive and motivation loss, but also depressive states and irritability are typical withdrawal symptoms.
- These are used approximately 12-24 hours after the last caffeine intake and can last up to nine days
- The lethal dose for an average adult is about 10 g caffeine or 200 cups of double espresso.
Properly dosed caffeine can do a lot of good things like:
- Increase of athletic performance.
- Use in pain and migraine therapy.
- Treatment of breathing arrest of newborns
- Prevention of chronic lung diseases
- Promotion of hair growth.
- The dehydrating effect helps against swelling, e.g. the eye part
- Smoothing and tightening of the skin, e.g. with cellulitis
- Promotes blood circulation
- Stimulation of cell renewal, with peelings
- Activates enzymes that cleave fat.
- Has anti-inflammatory properties
- Regular, moderate coffee enjoyment prevents skin cancer.
- Coffee drinkers have more sex and longer. (This is the reason why women, men still ask for a coffee after a date 😉
If this is not enough reason for another coffee …
