Caffeine is the most commonly used psychoactive substance.
Apart from being used to “wake up” caffeine dilates the airways and therefore is medically good, for example, for asthma patients (in proper dosage you can get from your family doctor).
New studies show that moderate consumption of caffeine (3-4 cups per day):
- Lowers the chance of developing a depressive condition, as long as it does not concomitant with an anxiety disorder.
- Reduces slightly (but in statistically significant) suicides attempts.
- Reduces the risk of Parkinson’s disease (not dramatic but yet statistically significant.
- Increases certain cognitive functions in patients with Alzheimer’s disease (especially in its early stages) and slows down its progression.
Indeed, it is not for nothing that Caffeine is included in the World Health Organization’sessential drugs list.
So, is it dangerous? Lethal? – it can be!
- Consuming 6-8 cups of coffee per day can significantly raise blood pressure and heart rate.
- Caffeine can cause some aggravation in an anxiety disorder — when it already exists. It can impair sleep as well as the quality of sleep. The phenomenon is not common in the consumption of 3-4 cups of espresso per day – especially if you do not drink it two hours before bed.
- Caffeine can worsen heart failure if you already suffer from one
- While in most cases and for most people caffeine has a positive effect on the raspatory system, it can be dangerous for newborns with lung problems.
- Finally, caffeine is toxic in high doses. 150 cups of espresso consumed at once can cause death.
