Oh, God. You can’t remember the last time it was this cold. And the wind! It cuts through every layer you’ve piled on. It’s dark, you should go home, but instead you call an old friend: “Let’s meet at the Perch” (365 Fifth Ave., nr. 5th St., Park Slope; 718-788-2830). You order the house specialty, a hot buttered rum ($8). The bartender puts it together: five-year-old oak-aged Cruzan rum infused for two months with fresh ginger; cider seasoned with cloves, nutmeg, allspice, and orange slices; melted butter; and a cinnamon stick and twist of orange peel to garnish. You take a sip and your cheeks thaw, and you make a mental list: How many other ways can I generate heat this winter?
Draw People Closer
Kiehl’s Original Musk smells equally alluring on men and women (essential essence, one ounce for $42.50; 109 Third Ave., nr. 13th St.; 212-677-3171).
Lips That Inflame
Yves Saint Laurent’s new Red Desire lipstick looks good by itself, but a layer of gold-toned Starry Dream over it makes an incredibly sensuous mouth ($28 each; 3 E. 57th St., at Fifth Ave.; 212-980-2970).
Slow Build to a Burn
First, the dark chocolate melts on your tongue; then the Mexican ancho and chipotle chiles kick in at the back of your throat (Red Fire Exotic bar by Vosges, $7; 1100 Madison Ave., nr. 83rd St.; 212-717-2929).
Sensualize the Bedroom
Get a ski-chalet feeling with Pottery Barn’s not-at-all-faux-feeling fur throw ($149; 600 Broadway, at Houston St.; 212-219-2420).
Wherever There’s a Draft
DeLonghi’s oil-filled radiator has a timer, so you can take the chill off your bedroom but not wake up at 4 a.m. in a sauna. Plus, it rolls easily from room to room ($79.99 at Gracious Home, 1992 Broadway, at 67th St.; 212-231-7800).
Keep Heat in the Feet
Cashmere socks wear out faster, but they feel so good while they last ($40 at Brooks Brothers, 1934 Broadway, at 65th St.; 212-362-2374).
Follow Casanova’s Lead
The Art of Seduction is the classic text on the rules of sex and power throughout history ($18 at Barnes & Noble, 33 E. 17th St., nr. Broadway; 212-253-0810).
Chase the Chill
The Open-Flame Option
The glass-enclosed fireplace in the newly redesigned lobby of the Royalton hotel is double-sided, so twice as many people can get closer to the flames (44 W. 44th St., nr. Sixth Ave.; 212-869-4400).
Shared Body Heat
On Monday nights, Lafayette Grill becomes tango central, with lessons followed by dancing until 1 a.m.; watching the pros outdo each other is worth the $10 cover (lessons, $5 per person with Ensueño Tango Salon; 54 Franklin St., at Cortlandt Alley; 212-732-5600).
The Community Shvitz
Wall Street Bath & Spa is clean, not too crowded, and has a deep cold plunge, salty seltzer from Russia, a lap pool, a cigar room, a billiard room, a restaurant, and big-bellied men strutting around in flip-flops (it’s co-ed) ($32.50 for the Old American Shvitz; 88 Fulton St., nr. William St.; 212-766-8600).
Single-Use Heaters
Once unwrapped, these card-size adhesive warmers radiate for several hours. Attach one to a chilled extremity, or fold it in half and carry it in your pocket (99 cents at JAS Mart, 35 St. Marks Pl., nr. Second Ave.; 212-420-6370).
