18 little things to cool you down on a hot vacation

There’s nothing like a cool breeze in your face — even if you have to create that breeze yourself. Tote a fan along, whether it’s an old-school paper version, a battery-operated number that fits in the palm of your hand or a fancier, pricier gadget that wraps around your neck.

If you are traveling light, choose a collapsible bottle that pops up or rolls out. For longer outings, a model with double insulation will keep beverages cold from sunup to sundown.

Bar said unless strenuous exercise is on your itinerary, you do not need to drink beverages spiked with electrolytes or extra vitamins. “Your kidneys are pretty smart,” he said. “They know how much sodium and potassium you need.”

Anyone who has visited a theme park in summer has probably noticed a fashion trend: thin, damp towels draped around flushed necks. Take the hint from those who brave the Florida heat in August and soak, wring or snap the fabric to take a bite out of the heat. Re-wet for a refresh.

If hot temps irritate your skin, sprinkle Snake Brand’s Prickly Heat powder on the affected areas and you can almost hear your body’s largest organ sigh with relief. The main ingredients — talc, menthol, camphor — soothe itchy rashes and bumps and prevent future epidermal meltdowns.

Face spray works like ocean spray. The dewy drops draw out the heat in your cheeks, chin and forehead, or wherever you spritz. Evian makes a version, as do cosmetic companies and the old-guard apothecary Thayers, which infuses its mist with witch hazel.

A UV umbrella offers movable shade while blocking harmful rays from beaming down on you. Unlike your clothing, go for black, which absorbs heat, and choose an SPF of at least 50.

To prevent rubbing and irritated skin, smear an anti-chafing stick on the insides of both upper legs. The moisturizing balm creates a defense barrier, so that when your thighs meet again, they won’t cause any friction.

If Spanx and the anti-chafing stick collaborated on a fashion line, they’d create the cooling short. The high-tech, wicking fabric pulls heat away and helps cool the body without adding extra bulk or unseemly seams.

Tote a small insulated bag to keep snacks (and maybe your cooling towel, when you aren’t using it) at refreshing temps. You can freeze a small bottle of water to serve as an ice pack — and drink it once melted. One Post colleague said she packs her bag full of “cold fruit for my kids, which also keeps them hydrated.”

Sure, backpacks keep your hands free and store a lot of stuff. But in summer, they also “trap too much heat,” one colleague points out. Pick an option that drapes a little more loosely but still travels well, like a cross-body bag or hip pack.

If your vacation will be active — or if athleisure is just your go-to wardrobe — pick clothes designed to dry quickly and keep sweat away from your skin. Sweat-wicking socks tout the added benefit of reducing the risk of blisters.

Listen to science — and several of our Post colleagues: Linen is the way to go if athletic wear isn’t in the dress code. On a molecular level, fabric experts say, linen beats cotton at moisture removal and airflow.

Bar, the physician, favors a “boonie,” which has a wide brim that protects everything above the neck. Some styles come with vents and a tail flap that covers the neck. You can also try a bucket hat; just pull it down low to protect any protruding parts from burning.

The more rugged relative of the Cuban guayabera is ideal for steamy settings because of its boxy, breezy fit that lets air stream through like a screened-in porch. Choose an option with vents to maximize the effect.

Spent too much time in the sun? A bottle of aloe vera gel — especially when chilled — can provide relief from a burn. But an ounce of sun prevention is better than a pound of goopy cure. Make sure to use a strong sunblock and save the aloe for later.

If a towel won’t cut the heat, a cooling tube around the back of your neck might do the trick. It starts out frozen, so it’ll be good and cold.

Used for medical purposes like swelling reduction or postpartum relief, instant cooling packs don’t require refrigeration and can provide some temporary chill.

Carry a resealable packet of baby wipes or face towelettes for swiping away sweat and grime. You’ll feel as refreshed as if you had splashed around in a fountain, but without getting dripping wet (or breaking the law).
