Tele-triage for Heat Exhaustion (Mild)

Audience: adult

Heat exhaustion is a common condition caused by prolonged exposure to high temperatures, often combined with dehydration. It typically presents with symptoms such as heavy sweating, weakness, dizziness, headache, and nausea. Mild heat exhaustion can often be managed safely at home with proper care. Telemedicine can help assess symptoms, provide guidance on cooling measures, and advise when in-person care is necessary. However, if symptoms worsen or red flags appear, immediate medical attention is crucial. This guide helps adults understand how tele-triage can support mild heat exhaustion and when to seek emergency care.

Red flags — go in person / ER

• Confusion, difficulty speaking, or loss of consciousness — call emergency services immediately.
• Body temperature above 39°C (102°F) — seek urgent medical care.
• Persistent vomiting or inability to keep fluids down — get prompt in-person evaluation.

What telemedicine can do

• Assessment of mild symptoms such as dizziness, headache, heavy sweating, and weakness.
• Guidance on home care measures including hydration and cooling techniques.
• Advice on when to seek emergency or in-person care.

What telemedicine cannot do

• Severe symptoms such as altered mental status or loss of consciousness.
• High fever indicating possible heat stroke.
• Seizures or persistent vomiting preventing fluid intake.

What Is Heat Exhaustion?

Heat exhaustion occurs when your body overheats due to prolonged exposure to heat and insufficient fluid intake. It is a warning sign that your body is struggling to cool down. Common symptoms include heavy sweating, weakness, rapid pulse, dizziness, headache, and nausea. Recognizing these early signs can help prevent progression to heat stroke, a more serious condition.

How Telemedicine Can Help

Through a telemedicine visit, a healthcare provider can evaluate your symptoms, ask about your environment and recent activity, and guide you on immediate steps to cool down and rehydrate. They can also assess risk factors like age, existing health conditions, and medication use. Tele-triage helps decide if you can safely manage symptoms at home or if you need urgent in-person care.
