Coffee - programmers' fuel is not fuel. It’s credit.

The article discusses the common belief that coffee gives you extra energy. The authors point out that coffee, particularly caffeine, acts as a stimulant that can make us feel more alert for a while. However, the energizing effects are temporary and shouldn’t be confused with a real increase in energy. Caffeine works on our nervous system, which is why we may feel a boost after consuming it, but it’s an illusion. Over time, the body becomes tolerant to the effects of caffeine, leading to the need to increase intake just to achieve the same results. It is important to understand that coffee cannot replace proper sleep and a healthy diet, which are the fundamental sources of energy.
