Latent toxoplasmosis is known 1) to impair reaction times in infected men [ 6] and animals [ 20] and also 2) to increase the concentration of testosterone in infected men [ 21- 23].
Latent toxoplasmosis, protozoan parasitosis with prevalence rates from 20 to 60% in most populations, is known to impair reaction times in infected subjects, which results, for example, in a higher risk of traffic accidents in subjects with this life-long infection.
Not to mention that alcohol impairs reaction time and judgment, both of which are crucial in an emergency.
Pergolide improved reaction time for high-span subjects and impaired reaction time for low-span subjects.
Ketamine, a N-methyl-d-aspartate (NMDA) receptor antagonist, impairs reaction time performance and interacts with foreperiod duration, thereby suggesting that ketamine alters motor preparation.
He said: "Fire-associated risks increase significantly over Christmas - from the distractions of a crowded house while cooking, impaired reaction times from alcohol consumption, dangers of overloaded sockets, flammable decorations and unattended candles".
Moss found that those who were smelling lavender performed significantly worse in working memory tests, and had impaired reaction times for both memory and attention-based tasks, compared to controls.
Insufficient sleep impairs reaction time, judgment and coordination, all of which could impact physical functioning.
In humans and some other primates, elevated blood ethanol concentrations (BACs) can affect performance, impairing reaction times, manoeuvrability, spatial orientation, and reasoning [12] [14], which may lead to reduced survival.
In addition, while sleep deprivation alone does not seem to significantly impair physical work capability, exercise compounded with sleep deprivation appears to increase vulnerability for negative mood disturbances and impaired reaction times [ 3– 5].
The most plausible explanation for such conflicting results is that, on the one hand, reaction times increase with duration of infection and, on the other hand, the infected drivers are able to gradually adapt to their impaired reaction times.
