What saves us in the morning after a hard night? The natural answer to this question is coffee. The most popular drink certainly invigorates and helps a lot of our efforts to look fit at the beginning of the working day.

Believers in the miraculous potential of coffee should know that sleep deprivation disrupts a very wide range of processes related to the work of the mind, concentration and quick thinking.
Lack of enough sleep reduces a person's ability to be alert and solve cognitive tasks that require good fitness. To test this possibility, the effect of caffeine on visual acuity was studied, as well as maintaining a sufficiently good concentration, which helps to solve complex tasks.
The result shows that stimulus from caffeine it happens and it helps to focus, but not for long.
Two tests were used in the experiment involving 276 volunteers. One for determining the ability to concentrate, and the second - to perform complex cognitive tasks related to a good assessment of a situation and the reaction to it.
The participants were divided into two groups. Some went home to sleep, while others were awake. In the morning, everyone received capsules with 200 milligrams of caffeine or placebo, and the test was repeated.
The results show that lack of sleep has had a very negative impact on the performance of the group that was awake. Caffeine has only helped with a simplified attention test. In more difficult the substance is powerless in most participants.
The bottom line is that coffee will ensure wakefulness if it is a goal, but cannot eliminate errors due to fatigue. Caffeine only increases energy and reduces the desire for sleep, but it cannot replace it. Therefore, in the case of important commitments, good long-term sleep is important, because coffee cannot do what sleep does and gives to the body.
