The boss provides coffee, employees provide motivation, stay awake and active at all times, and work long hours without diminishing efficiency. Although we think we know a lot about coffee, we inevitably have a little doubt about being ashamed to ask questions. Here's all about caffeine:

Caffeine relieves the discomfort of desk work

Programmers always stay excited, and the secret is caffeine. Caffeine can reduce the discomfort in the neck, shoulder, forearm and wrist caused by using the keyboard for a long time.

Coffee is a social lubricant.

Researchers at the Massachusetts Institute of Technology have found that having a cup of coffee with colleagues during a break can improve productivity. They tracked a call center team and found that colleagues would perform better if they could have a coffee break together.

The study of Consumer Survey Daily proves the effect of environmental noise on work efficiency. They found that as low as a slight level of ambient noise, such as the voice of a coffee shop, contributed to increased productivity. A Virginia startup team has even developed a "coffee noise" that mimics the sound of a cafe.

The best time for coffee is at two o'clock in the afternoon

According to the NHS, energy is at its lowest at 2: 16:00, when a coffee break is best, depending on age, weight and caffeine tolerance. generally speaking, 15 to 30 minutes is the better choice. Tip: take a 15-minute nap after drinking coffee and wake up with the effect of caffeine coming into play.

Caffeine can make stressful situations more stressful.

Caffeine can make nervous people more nervous. Specifically, elevated blood pressure and epinephrine levels, both of which are associated with stress, do not go away even after work.
