What do journalists, CEOs and plumbers have in common?
They’re among the top consumers of coffee and have to be hooked up to the coffee drip to properly function on the job, says a new survey.
A recent survey by the UK-based PR firm Pressat says that 85 percent of the 10,000 workers questioned drink at least three cups of coffee a day. And 70 percent said their working ability would be affected if they didn’t have any coffee at all.

Some professions, however – those with high stress levels, not surprisingly – are more addicted to coffee than others.
Here are the 10 professions that consume the most coffee:
- Journalists and media staffers
- Police officers
- Teachers
- Plumbers and trade workers
- Nurses and medical staff
- Company executives
- Telemarketers
- IT support

People (from all over the globe) generally prefer drinking coffee between 4 a.m. and noon to wake up, with a strong preference for the hours between 5 a.m. and 8 a.m., according to data from Jawbone, which provides data analysis based on its weight management wearable fitness tracking devices. The least favorite time for drinking coffee is at 1 a.m.
Caffeine jogs people’s memory and concentration and helps workers make fewer mistakes on the job, according to a study done four years ago by the London School of Hygiene and Tropical Medicine.

Drinking coffee can also help reduce accidents at work, traffic crashes and even medical errors by doctors who are on call for long hours at a time.
Some people consume too much coffee, though, and are unaware of the negative consequences of it on their health, such as anxiety, insomnia, strokes and heart problems. Pressat found that 62 percent of workers aren’t aware of coffee’s health risks.
Up to 400 milligrams of caffeine a day, or roughly four cups of brewed coffee, seems to be safe for most healthy adults, according to the Mayo Clinic.
If you’re looking to curb your caffeine habit, the Mayo Clinic recommends keeping tabs on how much you drink each day, switching to decaffeinated coffee and gradually cutting back by replacing coffee with herbal tea.
