You’ve probably been drinking a lot of water lately, and you’ve probably started feeling thirsty.
But a new study suggests that’s not the only way to become thirsty, and it might actually be the best way to get sick.
Researchers from Duke University and the University of Rochester found that people who drink more than their daily recommended daily intake of caffeinated beverages—like, say, a caffeinated coffee—have a higher risk of developing an infection.
“It’s an interesting finding,” says Jessica L. Tompkins, a professor of environmental health at Duke who led the study.
“If you drink a lot, you’re more likely to have a high risk of getting an infection.”
In this case, researchers wanted to determine whether drinking too much coffee could also increase your risk of catching the deadly H1N1 swine flu.
“People drink a ton of coffee, so what happens when you drink too much?”
“We thought it would be a good way to look at it from the perspective of drinking a ton and not having any symptoms.
And it’s not.”
Tompkins and her colleagues looked at data from the Centers for Disease Control and Prevention’s H1O1 Influenza Surveillance Network.
The network collects data from health care providers, coronavirus surveillance teams, and other sources and uses it to track the spread of the virus.
It then makes that data available to researchers who use it to understand how the flu is spreading.
In the case of the H1M1 study, the researchers looked at the data for H1Ns from October to March of this year, when about 1.6 million people had been exposed to the virus through the flu shot.
To identify people who had the virus, they tracked people’s flu symptoms and tested their saliva for the virus in a lab.
The results were surprising.
While drinking more than a cup of coffee was associated with a higher chance of having a high fever, the people who drank a lot also had a higher rate of having an elevated rate of pneumonia and the most common cold.
People who drank five or more cups of coffee had the highest risk of pneumonia.
And the researchers found that drinking two or more glasses of water a day was associated at least in part with increased rates of both pneumonia and pneumonia-related symptoms.
“People who drank coffee and drank a ton have a higher incidence of both respiratory and gastrointestinal infections, and those are very high risks,” Tompins says.
“So the question is, what is going on here?”
In their research, Tompaks and her team looked at a group of more than 7,000 people who were part of the CDC’s Influenza Outbreak Surveillance Network, a system that monitors the spread and the health of the US population.
The data came from the U.S. Census Bureau, which collected the data from a variety of sources, including state and local government, the CDC, and the state’s own health department.
The team found that the people in the H2M2 study who drank more than five cups of caffeaffe per day had a 50 percent higher risk than the rest of the population for having an increased risk of having respiratory infections.
The people who ate caffeinated food had a 33 percent higher chance.
Drinking more than one cup of caffeination a day also increased the risk for having a fever, with the average person who drank two or three cups of caffeine a day having a 42 percent higher fever risk.
While the results of the study were unexpected, the findings are not surprising to many.
In fact, many people drink coffee regularly, and that is the standard approach in most countries.
People often consume caffeine to help control their caffeine intake.
And many people are actually drinking it as part of a regular lifestyle, according to Katherine M. Smith, PhD, director of the Center for Health Promotion and Epidemiology at the University at Buffalo School of Public Health.
“There’s a lot that we know about what coffee is doing in our bodies,” she says.
The study, which was published in the journal PLOS ONE, involved more than 11,000 participants.
The researchers included a nationally representative sample of adults aged 18 to 80 from the United States, Canada, France, and Germany.
The researchers did not determine whether the people drinking the most caffeinated drinks also had the greatest risk of illness.
Instead, they used the data to track trends in drinking and how it affected people’s respiratory, gastrointestinal, and metabolic illnesses.
“The fact that drinking more is associated with an increased likelihood of having pneumonia and having an increase in the number of infections that we see is a real indicator of how the system is working,” says Tompys.
“When you’re drinking more, your body starts producing more sugar, which is a chemical that you’re going to have problems with, particularly if you have diabetes.”
So, what should you do to avoid getting sick?
“You shouldn’t be drinking caffeinated foods,” says Smith
