This pattern is classified as ‘Exterior’ not because it derived from an external pathogenic factor but because its manifestations are located in the ‘Exterior’ of the body such as the skin, muscles and Channels.
The Defensive Qi reacts to the external Heat Evil and the battle between the two gives rise to 'fever'. The fever here does not necessarily indicate an actual fever, but rather the patients' objective feeling of the heat. The Aversion to cold is the consequence of this fever.
This pattern is quite similar to Exterior-Cold, but with Heat related manifestations. The main difference is the feeling of thirst and slightly sweating. Dryness often accompanies Heat, hence the symptoms of feeling thirst. There is no Cold Evil constraining the skin pores, therefore the patients sweat slightly.
The Heat also goes up to the Head and causes headache and red tongue. However, the redness is on the tip or on the sides, which indicates the Exterior feature of the pattern.

Pulse type(s): Rapid (Shu) or floating (Fu)

Diagnosing a pattern in Chinese Medicine is no easy feat and should be left to professional practitioners.
In particular one has to know how to differentiate between different types of pulses and tongue coatings, shapes and colors. Here patients with Exterior-Heat will tend to exhibit rapid (Shu) or floating (Fu) pulses.
Practitioners also learn to read from a long list of seemingly unrelated symptoms. Here patients with Exterior-Heat might experience symptoms like headaches, aversion to cold, fever and sweating (full list here above).
