What are 3 common viral infections? The three most common viral infections are common cold, influenza, and bronchitis.

In some cases, the body may heal on its own. Does raising your body temperature help fight viruses? It has been shown that fevers which elevate body temperatures can help the immune system fight viruses. Second, it is possible that the body could misinterpret some substances absorbed from the gut as allergens during a fever. Finally, excessive fever can, on rare occasions, cause seizures, collapse and delirium--all of which may be further complicated by recent eating.

Fever can help fight infection, but sometimes it can climb too high for the body's own good. Internal body temperatures in excess of degrees F, for instance, expose proteins and body fats to direct temperature stressors. This form of heat distress can threaten the integrity and function of proteins accustomed to the body's usual temperature variations and the occasional less excessive fevers. Cellular stress, infarctions, necrosis, seizures and delirium are among the potential consequences of prolonged, severe fevers.

The receptor environment at the hypothalamus maintains limitations on high fevers. In the rare instances in which the hypothalamus itself malfunctions, the result is typically low body temperature, not elevated body temperature. Already a subscriber? Sign in.
