Many times you get a fever in the night, while you are hale and hearty during the day. This gives you restless nights and then, you are really tired in the morning.

This way you don't get a good sleep or rest that your body demands, and you have a real irritable self. What causes high fever only at night is a matter of big concern.

In case you are suffering from fever at night, you need to check on the symptoms first. The symptoms may be a loss of appetite, irritability, general weakness, dehydration, sweating, headache, chills and shivering, etc.

There are obvious causes that you can avoid to get rid of fever that visits in the night. What causes high fever only in the night, let's know.

Pyrogens that travel from outside and try to penetrate your body are what cause high fever only at night. You will see that these pyrogens tend to produce toxins that can be harmful to your health.

Within the body, these pyrogens are produced as a result of monocytes and macrophages. When external pyrogens enter the body, they induce the body to produce its own pyrogens, thus resulting in feverish conditions. This is one of the major causes of fever at night.

Common cold lasts for a few days while other infections depend on the patient's immunity and general time period.
