You have a fever, a sore throat and aching limbs - and you can hardly save yourself from advice. Some tips against colds are actually good, others are no good at all. We have investigated what helps with colds and what advice you don't even need to try.

Cold myth number 1: Hot lemon relieves a sore throat

Not true! Quite the opposite: the strong citric acid is not at all good for the already irritated throat mucosa. Although lemon contains a lot of vitamin C, in combination with hot water the vitamin C becomes ineffective. The vitamin content is zero due to the heating.

Cold myth number 2: Antibiotics are the very best remedy

Not true! Antibiotics only help with bacterial infections. However, a cold is a viral illness - and antibiotics are useless against it. What's more, they can actually do more harm than good due to their side effects. Only in the case of additional complications, such as an inflammation of the middle ear caused by bacteria, can the use of antibiotics really make sense for the patient.

Cold myth number 3: Moist calf compresses reduce fever

True! Moist compresses are really great for treating mild fevers. This is because the cloths give off an evaporative cooling effect on the heated skin, which helps the body to cool down - similar to sweating. This is how it works: Soak clean cloths in lukewarm water, wring out, wrap around the calves and secure with a dry cloth. Leave on for 20 to 30 minutes.

Cold myth number 4: A sauna works wonders for colds

Not true! If the cold already has the patient in its grip, it is better to avoid going to the sauna. This is because the body is busy fighting the illness and the intense heat in the sauna only puts even more strain on the circulation. However, regular visits to the sauna do help prevent colds.

Cold myth number 5: Staying in bed is a good decision

That's right! A flu-like infection puts a huge strain on our immune system because it has to produce a lot of defense cells. Bed rest helps the body to concentrate on this task. If you have a fever, you should definitely stay in bed. When the cold subsides, a short walk will get your circulation going again.

Cold myth number 6: A cold bath stops the illness

Only partly true! A cold bath is useful at the first signs of a flu-like infection. The reason: it promotes blood circulation and the aching limbs subside. However, if the cold is already acute, you shouldn't do it, because a hot bath not only puts a strain on your circulation, but on your whole body. If you do, then bathe for a maximum of 20 minutes and then go straight to bed.

Cold myth number 7: Warm beer helps with colds

That's right! The hops contained in beer help you fall asleep. Its bitter substances have an antibacterial effect. To enhance the effect, the beer should be drunk warm, in small sips and preferably with a little honey. However, the drink must not be hotter than 40 degrees, otherwise the valuable ingredients will volatilize.
