A fever can quickly dehydrate children due to the sweating and increased bodywork to fight infection. Keep their bodies at full fever-fighting capacity by having them drink a lot of fluids. Watch for chills, sweating, flushing of the cheeks, and shivering. These are all normal responses as your child’s body tries to fight off infectious invaders. Your child may also complain of muscle and joint pain, which are also normal responses as the body fights off illness. External cooling techniques such as a lukewarm bath and sleeping with fewer blankets are good ways of keeping your child comfortable during the flushing and sweating responses to the fever. A sponge bath with lukewarm water can make your child more comfortable. Do not make the child so cold as to shiver, as this will actually increase the body’s temperature as a default.  Cooling techniques encourage heat loss but do nothing to regulate the child’s internal temperature and thus are better used as comfort measures. You can use a fan in the room to improve air circulation, but don't position it so that it's blowing directly on your child. Your child may want to sleep a lot, which is a healthy response allowing the body to rest and focus on fighting the cause of the fever. Unusual grogginess and difficulty waking your child from slumber, as well as confusion, are cause for alarm and your child should be taken to medical attention at once.
