How many afternoons have you sluggishly moseyed over to the office coffee machine and wondered, Is this really my fourth cup of the day?

It explored the link between coffee and mortality, and included a total of 3,852,651 participants and 450,256 causes of death.

These findings held true regardless of the participants' ages, sex, smoking status, weight, or the amount of caffeine in the coffee they drank. They compared consumption of four cups of coffee per day and found that it was responsible for more reduction in cause specified death as well as deaths due to all causes when compared to consumption of no coffee.

The study's findings differ from previous research that suggest coffee can increase cancer risk.

According to the results, the the link between coffee and mortality in Europe and Asia was stronger than the association in the US. More consumption than this did not change the findings.

Other past research backs up the most recent findings about coffee and decreased risk of disease.

"It is hard to calculate, but my feeling is that drinking coffee possibly adds another couple of years to your life", said Astrid Nehlig of France's National Institute of Health and Medical Research in Sunday Times, explaining that part of the reason could be improved focus that a cup of brew brings. He added that more focus and attention could be the reason behind this longevity.

40 studies that were conducted previously were analysed by scientists during this research.

Researchers found that people who drank two and a half cups of coffee daily had a 17% lower risk of death from cardiovascular disease.

The researchers write that one in six persons are suffering from heart disease in Australia.

According to the World Health Organization (WHO), cardiovascular disease is the leading cause of death, yet one of the most preventable.

That doesn't mean that any and all coffee is bad for your heart, however.

The good news for coffee fans doesn't end there as study authors also believe that in addition to increasing life expectancy, drinking coffee also reduces the risk of developing and dying from cancer, cardiovascular disease, diabetes or respiratory disease.

In order to maintain a healthy heart and a healthy blood pressure, people must limit their coffees to fewer than six cups a day, researchers said.

The research team used UK Biobank data of 346,077 individuals aged 37 to 73 years. They also looked to see which study participants possessed a specific gene variant, called CYP1A2, that enables people to metabolize caffeine faster than those without the variant.

In other words drinking coffee can play a role in helping people to live longer.
