Over a quarter of British workers still went into work when feeling sick, with guilt over taking time off the main reason, research from Coffee Friend found.
Younger workers were the most likely to show up ill, with nearly 30% of 25 to 34-year-olds saying they often worked through illness.
Cold or flu was the most common excuse for calling in sick, used by 11% of those polled.
Nausea and vomiting followed at 9%, and 7% said they used a family emergency as a reason.
Michael Mensah, care coordinator at Careline Home Support, said: “Stir in one or two teaspoons of honey to soothe a sore throat and help calm a cough.
“There’s plenty of research to back up the effectiveness of it. A pinch of cinnamon adds flavour and a hit of antioxidants.
“It won’t cure a cold, but the warmth can be comforting. Coconut oil mostly adds calories and creaminess, with little evidence that it helps cold or flu symptoms, so only include it if you want the extra energy.”
Mensah added: “Keep your coffee warm rather than scalding, sip water alongside it to stay hydrated, and if you’re prone to reflux, opt for a milder roast, a splash of milk, or decaf.
“Coffee can actually help you feel better in a few simple ways. The warmth can soothe a sore throat and sinuses, while a small amount of caffeine may take the edge off headaches and brain fog.
“It’s also an easy way to add honey, which can help calm a cough.”
He said: “For best results, stick to a small coffee in the morning with honey and a pinch of cinnamon, have another small coffee or a decaf at lunchtime if you want the warmth, then switch to caffeine-free drinks later in the day so your sleep doesn’t take a hit.
“Coffee won’t usually dehydrate regular drinkers, but it’s still important to drink plenty of water or broth.
“Pair that with rest, gentle pain relief if needed, and the usual common-sense precautions.”
