It is customary never to have a fever

Fever from stress

In fact, there is also a fever that originates from the psyche and is not triggered by a pathogen [29]. In the case of psychological stress, the body temperature usually stays between 37 and 38 degrees, but it can also rise further in the case of strong emotional events or chronic permanent stress. Antipyretic agents have little effect in these cases. Instead, you should address the root cause and reduce the stress.

However, it is not yet clear why psychological stress can lead to a fever. Researchers assume that the sympathetic nervous system (sympatheticus) plays a role in this. This belongs to the vegetative nervous system and puts the body in an increased willingness to perform.

Fever of unknown cause

However, there are also cases of fever that cannot initially be attributed to a specific cause. This is called "fever of unexplained cause," or FUO for short. Dr. Martin Fleck explains in a review what it is about [30, 31].

In classic FUO, the body temperature exceeds 38.3 degrees and the fever lasts for more than three weeks. In addition, a definitive diagnosis is still missing after an inpatient examination lasting at least one week. In between, those affected can be free of fever again and again until the fever suddenly returns.

In the past, these cases of FUO were ultimately ultimately attributed to cancer, since fever in these cases is an attempt by the body to fight back against the tumor. However, some types of tumors also produce pyrogens that adjust the setpoint for the body temperature in the hypothalamus. This can also lead to a fever.

Since cancer is now mostly discovered earlier, there are now more cases of inflammatory non-infectious diseases such as rheumatism, Hashimoto, multiple sclerosis, lupus and other autoimmune diseases. In autoimmune diseases, the immune system attacks its own body, and fever is often the first sign of the disease [30, 31].

Fever in dogs and cats

As mentioned at the beginning, animals can also develop a fever. For them, too, this is a completely natural immune reaction. In dogs, the normal body temperature is 37.5 to 39 degrees. In cats it is between 38 and 39 degrees, which is a little higher than in humans.

An increased body temperature in dogs and cats does not necessarily mean a fever, just like it does in humans. High physical activity, stress or a high ambient temperature can also cause the body temperature to rise. Fever, on the other hand, often occurs at the same time as other symptoms such as loss of appetite, exhaustion or disturbed bowel movements.

As in humans, fever can have a variety of causes in animals and does not necessarily have to be treated. However, if your pet is doing very badly, you should have it examined. Bacterial infections are often the trigger for fever [32, 33].

The measurement results in the anus are also most reliable in dogs and cats. If your pet does not want to trust you with its rear end, avoid adding stress by not forcing it to take a fever. Either have the vet measure the fever or take it slowly.

First, have your animal carefully inspect the clinical thermometer. Then simply hold the thermometer to your hind leg at first. If your dog or cat allows it, there will be a reward. Then press the thermometer very lightly on your thigh, again there is a reward. In this way, you will slowly feel your way towards your goal.

It is ideal if you have already taught your dog or cat to take a temperature in a healthy state. In the meantime there is even a specific doctor training so that the animal - should it ever need a doctor's visit - can be examined there in peace and not associate anything negative with the examination methods, because it already knows them from the daily training with you and thus rather brings a lot of fine treats in connection.

You can do this if you have a fever

  1. First and foremost, you should allow yourself or the person with a fever to rest so that the body can heal itself and does not consume additional energy.
  2. At the beginning of the fever, when the body temperature starts to rise (fever rise), it is best to support the body with warmth, because it deliberately increases the temperature to fight the pathogens. Wrap the affected person in a blanket or use a lukewarm hot water bottle. Cooling would be counterproductive at this stage.
  3. When the body temperature slowly drops again (drop in fever), one begins to sweat. Then the best way to support the body is to cool it slightly. Cooling leg compresses are an old home remedy. To do this, place some cloths soaked in cool water around your calves and cover them with dry cloths. The patient should not be cold. So cover them with a thin blanket. As soon as the calf compresses are no longer cool, you should replace them.
  4. When the fever is falling, you can also support the body with an antipyretic tea made from willow bark: Pour 1 teaspoon of willow bark with a cup of boiling water, let the tea steep for 20 minutes and then remove the bark. For the treatment of children with willow bark, you should first check with your naturopath or pediatrician.
  5. Drink plenty of water because the body needs more fluid (approx. 0.5 liters more water or tea per degree Celsius rise in fever). If there is a lack of fluids, this can be life-threatening. Linden blossom and elderflower tea promote sweating.
  6. In the case of loss of appetite, the feverish person should not force himself to eat, but rather listen to his own body. Perhaps you have a different appetite than usual, such as fresh juices, smoothies and light soups. Note: A sick animal usually doesn't eat anything anymore!

In principle, the same measures can be taken with children - with the exception of willow bark tea - as described above. Drinking a lot is especially important. Make sure that your child drinks something every 30 minutes so that the body does not become dehydrated.

Under the link below you will find a homemade cold tea for children with a fever. If your child does not like tea, they can also drink diluted juices: orange and pineapple juice, for example, are good sources of vitamin C.

Fresh bed linen and your favorite plush toy can also increase your well-being. In addition, take your fever regularly and give your child a lot of attention and affection. For more home remedies for kids with a fever, see the linked article.
