Red Flags & When to Go In Person for Heat Exhaustion (Mild) in Children

Audience: pediatric

Heat exhaustion is a common condition in children exposed to hot weather or physical activity. It happens when the body overheats and struggles to cool down. Symptoms often include heavy sweating, weakness, dizziness, headache, and nausea. Mild heat exhaustion can often be managed at home with rest, fluids, and cooling measures. Telemedicine can help assess symptoms and guide care, but it is important to recognize warning signs that require in-person evaluation. If your child shows severe symptoms or does not improve quickly, seek medical care promptly. Early recognition and treatment help prevent progression to heat stroke, a serious emergency. This guide explains when telemedicine is suitable and when to go in person for mild heat exhaustion in children.

Red flags — go in person / ER

• Confusion, difficulty waking, or loss of consciousness — go to emergency care immediately.
• Seizures occurring during heat illness — seek urgent medical attention.
• High body temperature above 40°C (104°F) not improving with cooling — seek emergency care.

What telemedicine can do

• Assessment of mild symptoms such as dizziness, headache, and nausea.
• Guidance on home care including hydration and cooling measures.
• Monitoring symptom progression and advising when to seek in-person care.

What telemedicine cannot do

• Severe symptoms like confusion, seizures, or loss of consciousness.
• High fever unresponsive to cooling.
• Inability to drink fluids or persistent vomiting.
