Longer days, barbecues in the garden, solo sunbathing at home (not in parks!) - there are so many things we love about the warm weather once it finally arrives.
But the inevitable heat rash, or prickly heat, (cue burning, stinging, itching - you get the drift) really isn't one of them.
So, in a bid to keep our limbs rash-free this summer, we enlisted the best dermatologists in the business, Dr Stefanie Williams and Dr. Justine Kluk, to fill us in on how to stop the unsightly (and oh-so-itchy) bumps from ruining your cool.

What Is Heat Rash?
Before we get to the good bit, it pays to know exactly what you're treating.
There's 'sweat rash' (prickly heat) and 'sun allergy' (PLE aka polymorphic light eruption), both have similar symptoms and are often confused, so here's what you need to know to be able to tell the difference.
'Prickly heat, otherwise known as Miliaria, occurs when sweat ducts get obstructed, sweat leaks then into the skin and the skin gets inflamed around that tiny leakage. A prickly rash appears with red, very itchy little bumps (papules)', explains Dr Stefanie Williams.
Uh, ouch.
'The sweat ducts can be blocked by an overgrowth of bacteria which normally live on our skin, which leads to a ‘sticky’ by-product blocking up the sweat ducts and trapping sweat under the skin. Up to 30% of people may develop this under certain trigger conditions, which is naturally most common in hot, humid climates', Dr Williams clarifies.

Although the effect they have on skin can look similar, PLE on the other hand is an allergy to the sun.
'PLE is a common form of a reaction to UV light that often occurs in young women in spring and summer. The name ‘polymorphic’ refers to the fact that the rash can appear in many different shapes or forms, although in one person it usually looks the same every time it appears', says Dr Williams .
The difference? The location of the ever attractive rash.
Dr Williams explains, 'They can look quite similar, but while heat rash occurs mostly in occluded skin areas prone to sweating, PLE occurs on skin that has been exposed to the sun recently (but traditionally might be covered with clothing, so isn’t ‘used’ to the sun).'
Your skin is at risk of UV exposure anywhere, and what with the sunshine being nothing short of divine recently (thank you, weather gods) it's never been more important to protect your limbs.

How To Prevent Heat Rash
Because prevention is always better than cure, right?
1. Choose The Right SPF
The obvious way to keep heat rash at arms length is to slather on the SPF religiously, but Dr. Justine Kluk mentions that it has to include both UVA as well as standard UVB protection to be worth your while in reducing the risks of breaking out in red bumps.
'Look for the UVA symbol or the words 'broad spectrum' on the label,' she advises.

2. Take A Course Of Oral Steroids
'For those whose holiday is ruined by prickly heat every year, taking a 5-7 day course of oral steroids starting a couple of days before you are due to travel may prevent a severe attack,' says Dr. Kluk.
However, as with all medication, Dr. Kluk stresses the importance of discussing this with a Consultant Dermatologist or GP experienced in heat rash and skin conditions.
3. Train Your Skin
'For PLE, prevention is an important measure. This can be attempted by slowly getting your skin used to the sun at the beginning of the sunny season or prior to a sunny holiday', explains Dr Williams.
Clever.
'But, of course, common sense should apply, so that the skin isn’t exposed long enough to burn', advises Dr Kluk.

4. Cover Up
As well as applying a sunscreen with both UVA and UVB protection, Dr. Kluk recommends investing in densely woven sun protection clothing, which can reduce the risk of heat rash even further.

5. Avoid Sweating As Much As Possible
We're not talking about applying layers and layers of deodorant. Sounds almost impossible but staying cool is the aim of the game.
'Prevention of sweat/heat rash includes avoiding sweating as much as possible. Even for only a few hours per day (e.g. an air-conditioned office) is helpful. Also, a cool shower during a hot day might help.
'Avoid over-dressing, occlusive clothes and friction/rubbing from clothes. Furthermore, you should avoid any irritation of the skin (e.g. excessive soap etc.) and avoid using rich, greasy moisturisers and heavy sunscreens', advises Dr Williams.
11 Of The Best Natural Deodorants For That Fresh Feeling Minus The Synthetics
This cult brand is loved by beauty editors and influencers, and for good reason. Not only is it super soft on underarms, but the gel formula glides on effortlessly. Our experts awarded it top points for a clear finish that didn’t leave any tell-tale white marks.
Our testers agreed and found it easy to use, long-lasting and kind to skin. They also praised its scent, with one describing it as ‘fantastic’ and like nothing they’d tried before.
Scoring top marks for its clean-cut and chic design, this solid natural deodorant from Caudalie not only looks great, but testers loved how easy it was to use and dispense, with no dragging on the skin.
Importantly, it gave testers long-lasting protection and didn't leave any pesky residue on underarms or clothes either. Fragrance wise, testers really enjoyed the scent, with one describing it as 'calming', while others said it has an 'earthy, fresh smell'.
If you're worried about sensitive underarms, then natural deodorants – which are free of chemicals that can be harsh on skin – could be the way to go. This cream balm from Drunk Elephant is pleasingly soothing and none of our testers suffered any irritation after use.
Our panel was pleased with how well the product worked and didn't notice any body odour, with one commenting that they were pleasantly surprised by how dry they felt. Some said the square shape of the bottle made it a little harder to use. And while some liked the sweet almond-like scent, others found it too much.
We don't only sweat from our underarms – it's something that naturally occurs all over our bodies, so why not protect these areas too? From chests to feet, this balm can be used all over. It's also plastic free, as it's dispensed from a metal tube (like an old-fashioned toothpaste tube) and comes with a little key to wind up the end and push out the product more easily.
Testers particularly liked the super fresh eucalyptus and mint scent and found it deodorised well, too. The only niggle was that it becomes much harder to dispense when it’s cold, as the balm comes out quite thick.
This balm from L’Occitane was highly praised by our testers for how moisturising and nourishing it felt on their underarms, while keeping them dry throughout the whole day, with zero stickiness. It also scored top points for its citrus fresh lemon and lime scent.
While many found the balm easy to apply – it's best done with your fingers – some said they would have preferred a little spatula to help with the job.
Just like we detox our skin with a weekly face mask, we need to do the same for our underarms. This deodorant uses AHAs – which are used in many exfoliating skincare products – to clear pores of any product build-up.
The rollerball design made it a breeze for gliding across armpits and it immediately got to work at masking odours, leaving our testers with fresh, dry underarms throughout the day.
This sage and mint-scented roll-on worked wonders on our testers, who said it kept them protected throughout the day without needing to apply an emergency top-up. The herbal scent might not be to everyone’s taste, but our panel did love the instant cooling and hydrating effect it had on skin.
Switching to a natural alternative usually means you end up paying twice the price, but not with this little roll-on. It’s formulated with soothing aloe vera and vitamin E, which our testers found was on the wetter side to apply, but it wasn’t greasy or sticky once dried.
The majority of our panel reported sweat-free armpits and loved that it didn’t leave any stains behind on clothing.
If you’re running late, the last thing you need is to have to wait for your deodorant to dry before you can even get dressed, which is where this Green People number comes in.
Our panel found it was quick to dry, and it left armpits with some added freshness. It also provided all-day protection. But the best bit? It’s designed to promote healthy bacterial growth, too.
The compact packaging of this little roll-on made it a winner in our testers’ books. They said it took a while to dry, but once it did, it left a sweet orange and pomegranate scent behind.
Two-thirds of our panel also said it made them feel fresher after use, with most finding it successfully masked odours.
Join the eco-friendly movement with this natural deodorant bar. It doesn’t contain any plastic packaging, and our testers said it left them with softer armpits, which were kept dry from AM to PM.
Testers did find it a little scratchy at times to apply, and there was some crumbling involved, but overall, it dried fast and didn’t stain white clothes.
How To Treat Heat Rash
1. Take A Daily Antihistamine
That's right, those little white tablets aren't just good for alleviating the symptoms of hay fever.
'Taken daily, an antihistamine may help to reduce the itch associated with the rash,' she advises.
Cetirizine, loratadine and fexofenadine are less likely to make you feel drowsy, but remember to take them as your GP, a pharmacist or the leaflet describes.

2. Swap Out Your Shower Gel
While there's nothing more luxe than a beautifully scented shower gel that lathers up a dream, you might want to swap it out for something kinder if you're battling heat rash.
Dr. Kluk recommends a gentle, emollient-based body wash as not to irritate the skin further.
Glossier's fan-favourite shower oil has been reinvented this month, but loyal latherers needn't worry: the rich, silky formula is now even more indulgent than before. There's that orange-blossom scent you know and love, and the sulphate-free oil texture leaves skin feeling so soft, you'll be back in that mini skirt in no time.
Despite being an ingredient synonymous with facial care, salicylic acid’s benefits – unclogging pores, smoothing and sloughing away dead skin cells – make it an excellent addition to your body care routine, too. Paired with nourishing glycerin, this Naturium body wash helps hydrate and tend to perennially dry limbs, too.
Augustinus Bader's recently launched body wash is predictably decadent. Harnessing a host of ingredients you might expect to see on the back of your skincare bottles, it features nourishing amino acids and peptides, helping to purifying your skin, calm any irritation and support the skin barrier. It's also the brand's first fragranced product, boasting an uplifting eucalyptus scent.
There are now so many stellar Byredo scents, it's tricky to whittle down a favourite: but Blanche is surely the one to unite us all. Crisp and clean like just-laundered sheets, it's the perfect fragrance to take into the shower with you. Keep the pepper and rose-tinted trail going with the matching body cream and perfume.
Consider this the body care version of your daily double cleanse. Like the brand’s much-loved skincare (see: the Protini Polypeptide Cream and the T.L.C Sakuri Facial) it’s enriched with a powerhouse of nutrients, helping to gently exfoliate the skin below the neck all while being gentle enough to use every day.
Inspired by the stress-reducing, shoulder-slackening benefits of forest bathing, this body wash doubles up as a softening scrub to cleanse and exfoliate skin. But its major USP, of course, is the scent which is thought to help reduce stress levels. Either way, it's a serious treat for the senses.
Kosas Good Body Skin AHA + Enzyme Exfoliating Body Wash
Formulated with a host of acids and enzymes, this foamy body wash will brighten uneven skin tones, tackle keratosis pilaris, and banish bacne in no time at all. Keep it in your gym bag – it's the perfect thing to reach for after a sweaty HIIT session.
Yes it's Chanel, so it's instantly covetable. But don't mistake this for a case of style over substance: the new formula foams up easily, a little goes a long way, and the frankly iconic scent lingers for hours on the skin.
This extra-foamy body wash is the best way to experience the eucalyptus scent that made Necessaire a name to know. Bracing and refreshing, it'll rinse away that sticky summer feeling while leaving limbs supple and soft.
Aromatherapy Associates De-Stress Oil-To-Milk Body Cleanser
From the undisputed leaders in aromatherapy bodycare, this silky shower oil is steeped in the famously effective De-Stress blend of frankincense and chamomile (which makes a nice change to the usual lavender.) A tip: pour it into your hands before taking three deep, long breaths.
Neal's Yard Remedies English Lavender Bath & Shower Gel
Here it is, the ultimate lavender body wash. There are many mimickers out there, but for the full, soporific effects of the sleep-inducing plant, it's Neal's Yard every time.
The secret? While most body washes use French lavender, this one uses British buds, which boast a stronger, sweeter aroma. With gentle cleansing agents, there's plenty of lather – as well as a great night's sleep – in store.
This sumptuous, decadent body wash is packed full of essential oils that leave skin both hydrated and beautifully scented. Ren uses only 100% natural fragrances, and this warm, woody rose trail is one of its very best. You'll want to repurchase immediately.
It might not come with much sex appeal, but Ameliorate's creamy body wash is the best way to get rid of those pesky keratosis pilaris spots. The secret is a dose of lactic acid, alongside gentle surfactants that cleanse without stripping the skin barrier.
The affordable option we've been recommending for years, Caudalie's floral shower gel, scented with ginger, jasmine and white musk, is sure to lift your mood. With a natural base of grape water (one of the mainstays of the brand), this plant-based gel is free from stripping soaps and foams gently, so you might just skip the moisturiser.
With intoxicating notes of violet, cardamom and leather, Santal 33 is the kind of scent that signatures are made of, so it was a total no brainer for Le Labo to shuttle it into a shower gel. This is filled to bursting with heaps of moisturising ingredients to banish rough, bumpy skin from tip to toe.
Hello Klean is the brand that made hard-water shower filters a chic affair – and now, you can bolster the effects with the brand's line of skin-boosting body products.
The Micronutrient Wash is a bi-phase shower gel that froths into a creamy foam once shaken, and works to sweep away the mineral traces left behind by hard water, thus stopping your skin from feeling dry and tight post-shower.
3. Apply A Steroid Cream
'For very itchy, raised, red or swollen areas, a steroid cream may be prescribed to relieve discomfort until the rash has settled', says Dr. Kluk.
According to the NHS, topical steroids also come in the form of lotions, gels, mousses and ointments and are available in a variety of different potencies depending on the condition of your skin. Hyrdocortisone and Eumovate can be bought over the counter, but stronger topical steroids are only available on prescription from a GP or dermatologist.

4. Switch Up Your Body Lotion
That piña colada-scented body lotion may be a brilliant addition to your summer bodycare routine, but it might not be doing your heat rash any good.
'Avoid putting anything on the skin that may irritate it further, such as perfume or heavily fragranced skincare products,' adds Dr. Kluk. 'Instead, apply a soothing moisturiser containing menthol or aloe vera to calm the skin,' she adds. 'To cool the skin down even more so, pop it in the fridge for half an hour beforehand.'
It's important not to lather on the thickest creams in your skincare arsenal either.
'Avoid heavy, greasy moisturisers, but stick to lightweight emollients or aloe vera lotion/gel. Anti-itch emollients such as Dermol lotion may also be useful to ease the itchiness', explains Dr Williams.
This ultra-light lotion is packed with skin-restoring, soothing aloe vera extract. It absorbs in seconds and takes the edge off of sore skin almost instantly. We love.

5. Stay In The Shade
Ok, this one's obvious, but when the lure of lying flat out on the grass with a tin of Gordon's Gin & Tonic in hand gets too much, remember, it'll only exacerbate your heat rash - not good.
'Seek the shade or stay out of the sun wherever possible for a few days to allow heat rash to settle,' says Dr. Kluk.
