31 Effective Home Remedies For Prickly Heat (Heat Rash)

Prickly heat, also known as sweat rash or heat rash, often plagues people during the summer season. It is medically called miliaria and it is a common skin issue that affects infants, teenagers, and adults.

Prickly heat can appear on any part of your body. However, it usually occurs around the groin, arm, feet, back, neck, chest, and abdomen.

People are more susceptible to prickly heat in hot, humid climes as such climate leads to excessive sweating which tends to cause blockage of sweat glands. When the sweat glands eventually open up, they tend to irritate the skin and cause prickly heat.

Other factors that increase the likelihood of having prickly heat include; poorly developed sweat glands, bacterial infection,  being overweight, and having a high propensity to perspire easily.

Common symptoms of prickly heat include; red round bumps or rashes that itch, a prickly sensation, and a mild inflammation.

Prickly heat normally goes on its own. However, you can take some actions to prevent it or hasten its dissipation. Such actions include;

  • Stay in air-conditioned rooms or keep your rooms well-ventilated.
  • Endeavor to stay cool especially during summer.
  • Take cold baths or showers.
  • Opt for loose clothing, preferably, those made from cotton.
  • Ensure you take a shower after exercising or working out.
  • Avoid exposure to intense heat and humidity.
  • Ensure you stay hydrated by taking plenty of fluids such as water, coconut water, and fresh fruit juices.
  • Endeavor to change your infant’s diaper often.
  • Stay away from direct sunlight.
  • Avoid using oil-based cosmetics.
  • Avoid scratching the affected areas as that may exacerbate the condition and lead to infection.
  • Dress babies in light-weight cotton.
