102°C (38.9°F) — Fever
A temperature of 38°C (100.4°F) or above is the clinical definition of a fever. This is the body's natural defense mechanism against infection.
What this feels like
Expect chills, sweating, headache, and fatigue. Most fevers in healthy adults resolve within 3–5 days with rest and hydration.
Key facts
- ✓Clinical fever threshold: 38°C (100.4°F) or above
- ✓Seek medical care if fever lasts more than 3 days in adults
- ✓For children under 3 months: any fever above 38°C requires immediate medical attention
- ✓Drink plenty of fluids — fever increases water loss significantly
102°C (38.9°F) — Extreme heat — health risk
Temperatures above 36°C (97°F) are extreme heat conditions. Heat stroke risk is significant, especially for the elderly, children, and those with health conditions.
What this feels like
Dangerously hot. Even resting in the shade can be uncomfortable. Air conditioning or cool indoor spaces are strongly recommended.
Key facts
- ✓Heat stroke can occur when body temperature exceeds 40°C (104°F)
- ✓Signs of heat exhaustion: heavy sweating, weakness, cold/pale skin, nausea
- ✓Stay indoors in air-conditioned spaces during peak heat
- ✓Never leave children or pets in parked cars — temperatures can rise fatally fast
