28 Effective Home Remedies and Tips To Get Rid Of Prickly Heat Fast
Simple cooling secrets that calm irritated skin and restore comfort during hot seasons.
Prickly heat—also known as heat rash or miliaria—causes annoying red bumps, itching, and skin discomfort during hot, humid weather. Whether you’re struggling with a mild rash after working out or battling persistent irritation during summer, simple home remedies and prevention habits can help you achieve fast relief and healthier skin.
What Is Prickly Heat?
Prickly heat, or miliaria, is a common skin problem triggered when excessive sweat clogs the sweat ducts, trapping perspiration beneath the skin’s surface. This causes tiny red bumps, itching, burning sensations, and, at times, blisters—especially in areas where sweat becomes trapped under clothing or skin folds. The condition occurs most often in hot, humid climates, but can also appear in cold seasons if you wear heavy or non-breathable clothing.
Common Symptoms
- Fine red or pink bumps (papules or vesicles)
- Intense itching or prickling sensation
- Mild swelling or tenderness in severe cases
- Most common around the neck, armpits, waist, chest, back, groin, and inner thighs
- Can progress to blisters in severe or recurrent cases
What Causes Prickly Heat?
Excessive sweating is the main culprit. Sweat that can’t evaporate accumulates under the skin, blocking the sweat glands. Over time, this leads to inflammation, irritation, and the characteristic itchy red rash. Several factors increase your risk:
- Wearing tight, non-breathable, or synthetic clothing
- Heavy exercise or strenuous activity in heat
- Using oil-based cosmetics that clog skin
- Bundling up in warm clothes (even in winter)
- Certain medications (e.g., ADHD, blood-pressure drugs)
- Hot, humid weather or poorly ventilated rooms
- Babies’ underdeveloped sweat glands make them especially vulnerable, especially if swaddled or in incubators
Understanding Types of Prickly Heat (Miliaria)
There are several forms, ranging in severity:
- Miliaria Rubra (Prickly Heat): Most common in children (1–3 weeks old) and adults in hot, humid environments. Causes red, inflamed lesions and intense itching.
- Miliaria Crystallina: Seen in newborns under 2 weeks, causes clear, non-inflamed blisters without redness.
- Miliaria Profunda: The rarest form; deep, flesh-colored lesions—typically in those with recurrent rashes.
28 Simple Home Remedies For Prickly Heat Relief
Natural home remedies can soothe itching, reduce redness, and support faster recovery of prickly heat. Try these solutions for safe, effective relief:
1. Aloe Vera Gel
Cool, moisturizing, and anti-inflammatory, aloe vera gently calms itching and reduces redness. Apply pure aloe vera gel directly onto the affected skin 2–3 times daily for best results.
2. Oatmeal Bath
Add 1–2 cups of colloidal oatmeal to cool bathwater. Soak for 15–20 minutes, then gently pat skin dry. Oatmeal’s natural compounds relieve itching and inflammation.
3. Cold Compress or Ice Cubes
Wrap a few ice cubes in a clean, soft cloth (never place directly on skin) and apply for 5–10 minutes. Repeat as needed for instant cool-down and itch relief.

Mix sandalwood powder with rose water to form a paste. Apply evenly over the rash, let dry, then rinse off with cool water. Sandalwood reduces heat and soothes irritation.
5. Fuller’s Earth (Multani Mitti)
Mix Fuller’s earth with rose water; apply the smooth paste to affected areas. Once dry, wash off with cold water for a cooling, calming effect.
6. Neem Paste or Neem Water
Neem’s antibacterial and anti-inflammatory action is ideal for rash-prone skin. Make a paste from fresh neem leaves or boil leaves in water, cool, and bathe skin with it.
7. Baking Soda
Dissolve 1–2 teaspoons of baking soda in a cup of water and dab on gently with a cotton ball. Its mild antiseptic and soothing properties help clear blocked ducts.
8. Calamine Lotion
Calamine is a classic remedy that provides lasting itch relief while drying up oozing lesions. Apply gently after cleansing.
9. Rose Water
Use pure rose water as a toner or compress; its cooling and anti-inflammatory benefits calm inflamed skin instantly.
10. Honey
Raw honey is soothing, antimicrobial, and helps accelerate healing. Apply a light layer, leave for 15–20 minutes, then wash with cool water.
11. Sandalwood Oil or Powder
Combine a drop of sandalwood oil with a carrier oil, or use sandalwood powder. Apply to rash-affected areas once or twice daily.
12. Cornstarch
Lightly dust cornstarch on clean skin folds to absorb excess sweat—never use on broken skin. Helps keep the area dry and comfortable.
13. Cucumber Slices
Place cool cucumber slices on the rash. Its natural antioxidants and vitamins soothe and cool the skin quickly.
14. Watermelon Pulp
Gently rub fresh watermelon pulp on the affected area. Its hydrating, cooling effect eases heat and irritation.
15. Potato Juice
Place thin slices of raw potato or dab cool potato juice on the rash. The starch component relieves itching and supports healing.
16. Yogurt
Apply plain, unflavored yogurt for 10–15 minutes, then rinse with cool water. It calms itching and adds moisture.
17. Talcum or Baby Powder
After a cool shower, use fragrance-free talcum powder or baby powder in skin folds to reduce friction and keep the area dry.
18. Apple Cider Vinegar
Dilute apple cider vinegar with twice as much water and use as a dab or rinse for its antibacterial properties.
19. Peppermint or Mint Leaves
Crush leaves and apply the juice to skin for a cooling sensation that instantly relieves itching and burning.
20. Coconut Oil
Natural coconut oil soothes, moisturizes, and helps treat mild inflammation. Best used after symptoms subside.
21. Avoid Scratching
Scratching increases infection risk. Instead, use gentle tapping or cool compresses to manage itching.
22. Hydration
Drink plenty of water and hydrate your skin from within to speed recovery and reduce further outbreaks.
23. Light, Breathable Clothing
Wear loose-fitting, pure cotton clothing to promote airflow and support healing.
24. Avoid Heavy Lotions and Creams
Steer clear of oil-based or heavy creams that can block pores and worsen symptoms.
25. Citrus Juices
Natural vitamin C from fresh lemon or orange juice supports skin healing. Drink diluted juice; avoid applying directly to open skin.
26. Bath in Cool Water
Cool showers help remove sweat, bacteria, and dead skin cells that contribute to rash formation.
27. Clean, Dry Towels Only
Always use soft, clean towels to gently pat skin dry after showers or remedies.
28. Regular Sweat Removal
Wash away sweat promptly after activities—especially in body folds—to prevent pore blockage and recurrent outbreaks.
When To See a Doctor
Most cases resolve within a few days using the remedies above. However, seek medical advice if you notice:
- Extensive blistering or oozing
- Severe pain or swelling
- Signs of infection (pus, redness spreading, fever)
- Rashes lasting more than a week
How To Prevent Prickly Heat
Prevention is even better than a cure. Build these simple habits into your summer routine:
- Wear light, breathable cotton or linen fabrics

- Keep bedding and towels clean to avoid accumulation of bacteria or sweat
Dietary and Lifestyle Tips
- Focus on hydration—add coconut water, lime juice, watermelon, or cucumber to meals for extra fluid intake
- Include cooling foods like buttermilk, yogurt, and fresh fruits
- Avoid spicy, oily, or fried foods that may increase sweating
- Bathe after outdoor activities to remove trapped sweat and dust
- Manage weight to reduce skin folds prone to sweat stasis

Frequently Asked Questions (FAQs)
How can I get rid of prickly heat overnight?
While most cases take a few days to heal, rapid symptom relief is possible by applying aloe vera gel, taking a cold oatmeal bath, using calamine lotion, and keeping the skin dry and cool at all times. Avoiding sweat triggers during sleep (like thick blankets) also helps.
Is prickly heat contagious?
No, prickly heat or heat rash is not contagious. It is caused by blocked sweat ducts—not infections or bacteria spread from person to person.
Can babies get prickly heat?
Yes, babies and infants are highly susceptible due to their immature sweat glands, especially when over-bundled. Use airy, loose-fitting cotton clothes and keep nurseries well ventilated.
What are the do’s and don’ts for prickly heat?
- Do: Bathe with cool water often, use gentle cleansers, keep skin dry, wear loose, breathable clothing, and try natural remedies.
- Don’t: Scratch the rash, wear tight or synthetic clothes, use harsh chemicals or thick creams, or ignore signs of infection.
Can prickly heat be painful?
Generally, prickly heat is not painful but may cause intense itching and a prickling, burning sensation. Scratching can cause tenderness and—if skin is broken—lead to secondary infection.
