"no it doesn't"
Erm yes it does - that or the UK government has forced me to do a whole compulsory unit on the Nervous System and Caffeine etc.
It's because caffeine is a stimulant.
This stimulant stimulates the synapses - mean messages travel faster along the Central Nervous System.
It also causes blood to pump faster around the body - allow more oxygen to get to muscles speeding up the body's working time in general.
That's all I know...
I'm currently doing a School Report for this, and with my results, yes - it does affect reaction times. It reduced the reaction times on all three subjects in my experiment.
After carrying out the ruler drop test before caffeine and injesting a cup of coffee and waiting 20 minutes my reaction time increased after the caffeine intake.
no- we did a test at school
temporarily yes
yes it does
Caffeine increases the reaction time to visual and auditory stimuli
I belived that givng caffeine to a plant will cause i it to have no reaction to the caffeine
blad
it effects the nervous system in some cases making the body have spasms
When your measurement is close to the reaction time.
Man, I don't know!
Ot can temporarily slow them somewhat.
Caffeine is a stimulant, which is the reason it could affect your typing speed.
A caffeine could possibly cause a rash, but only if you have some kind of allergic reaction to caffeine.
Caffeine does not affect how well birth control works. Thank goodness!
Caffeine can be synthesised (made artificially in a lab) by reacting dimethylurea with malonic acid.
According to the ingredients label, red bull includes taurine, glucuronolactone, and caffeine which are psychoactive stimulants (they increase physiological and nervous activity).
