Why do fevers spike at night?

My son's fevers always are worse at night. I want to know why do fevers spike at night?

Infections get worse at night because you're lying flat and drainage from the head sinuses ears is reduced. Infection percolates in these areas and can cause fevers at night. After waking up in the morning and assuming an upright position things tend to drain out.
