Going outside to play is generally not recommended for children with a fever. Children’s fever is mainly caused by bacteria, viruses and other infections. At this time, the child not only has an elevated body temperature, but also often has symptoms such as muscle aches and weakness and fatigue. If you take your child out to play outdoors, you may be overly fatigued, which affects the child’s immunity, thus aggravating the fever and is not conducive to the recovery of the disease, so it’s best to avoid going out to play when your child has a fever. In addition, taking a child with fever out to play under the influence of external factors, such as being cold, may cause the body temperature to continue to rise, affecting the recovery of the disease. At the same time, children brought to play in densely populated areas with poor air quality may lead to cross-infection, which may aggravate the symptoms of fever. It is generally not recommended to play outdoors when your child has a fever. It is recommended that you seek medical attention to determine the cause of your fever.
