35. Prickly Heat | When the Body Blocks What Needs to Flow

In this episode of Mohivate, Dr Mohi Sarawgee explores one of summer’s most familiar yet misunderstood conditions : Prickly Heat. A rash so common that most of us have experienced it, treated it, or complained about it without ever really understanding what is happening beneath the skin.
The episode begins with the name. Prickly heat is medically known as miliaria, from the Latin word milium, meaning millet. The story travels from Roman physicians who first described it to British soldiers itching their way through India, Southeast Asia, and the Pacific, where the rash became such a military concern that researchers eventually studied it formally in tropical conditions.
The science follows the sweat. From the remarkable efficiency of eccrine sweat glands to what happens when a sweat duct becomes blocked, Dr Mohi explores why prickly heat develops and how skin bacteria can turn a minor irritation into something far more uncomfortable. The three forms of miliaria : Crystallina, Rubra, and Profunda, are explained clearly, including what each type means, who is most at risk, and when a doctor rather than a pharmacy is the right call.
Practical guidance covers acclimatisation, clothing, skin care, prevention, and treatment, including why the answer has never been an enthusiastic application of powder.
With clinical insight, personal reflection, humour, and a thread that runs beyond the skin itself, this episode asks a simple question: what happens when something designed to flow becomes blocked? Because sometimes the smallest discomforts are simply the body’s way of asking us to pay attention.
This episode gives prickly heat the conversation it has always deserved.
