Selena Gomez and Molly Sims both swear by this sleep trick that ‘goes a long way’ – does it really work?

Forget sleeping like a baby – we want to sleep like a millionaire celebrity.

And when some of them—namely Selena Gomez, Molly Sims, and Nicola Peltz Beckham—swear by the same essentials to send them to sleep, it’s worth considering.

Supermodel Molly, 51, is the latest to rock the nighttime essentials.

“Listen, you can’t beat a heater,” she told Parade of her main sleep revenge. Every once in a while, a heating pad can really go a long way.” But she doesn’t even sweat at night, adding: “I make my room super, super cold.”

She also likes a red light mask, a magnesium supplement and blackout curtains.

Selena Gomez, 32, also guarantees some warmth under the blanket. In a 2020 Instagram video, she detailed her process of unwinding at the end of the day.

“[I] I shower, wash my face and then when I go to bed my friends laugh at me but I have a heater. It’s almost like an anxiety blanket. It feels very nice,” she said.

And Nicola Peltz Beckham – daughter-in-law of Victoria and David Beckham – said she uses one too.

“My in-laws keep the house so cool. Whenever I know I’ll be there, [a heating pad] it’s a must because I can’t sleep in that temperature. I feel like I’m sleeping in a refrigerator,” the 29-year-old told Strategist earlier this year.

“At home, my husband, Brooklyn, likes the room at 60 degrees, which is absolutely wild. I always have this with me, even on the plane. It’s my comfort thing.

But wait, isn’t cold better for sleep?

Many experts tend to agree that a cooler room is more conducive to a better night’s sleep. The Sleep Foundation says 65 degrees is the magic number, while the Cleveland Clinic recommends setting the thermostat to 60 to 67 degrees to turn your bedroom into a “cool, dark and quiet” cave.

Dr. Alex Dimitriu, a California-based psychiatrist and sleep doctor, previously told The Post that a cool room — between 60 and 67 degrees — is best for getting to and staying asleep.

According to Cleveland Clinic Sleep Psychologist Michelle Deru“Heat is a major disruptor of REM sleep,” the stage of sleep associated with dreaming.

Okeanis Vaou, MD, FAAN, a UT Health San Antonio neurologist, said our brains are also working to cool our bodies.

“When you’re about to go to bed, you feel cold. This is because your body refreshes you by preparing you for sleep. Your body turns off your internal thermostat to lower the temperature because this is how our body prepares for sleep. Our brain wants a cooler temperature when we sleep,” she said.

So are the stars wrong?

That depends. If they’re keeping that heating pad next to their feet, that might help them.

“Heating the feet can have a positive impact on sleep for many people, mainly due to its effect on promoting lower body temperature and relaxation,” explained Dr. Biquan Luo, a biomedical scientist based in San Francisco.

Using a heating pad down there—or wearing socks—can dilate the blood vessels of the legs, allowing them to carry more blood. That blood is then removed from other parts of the body.

“As a result, it can help dissipate body heat and lower core body temperature,” said Dr. Increased rent.

According to Dr. Christine E. Dickson, psychologist, heating pads can also help fight insomnia in people who experience pain, muscle stiffness or circulation problems.

“The warmth created by the pillow can help relax muscles and soothe pain, which can make it easier to fall asleep,” she said.

“In addition to promoting relaxation, heating pads can also help improve circulation, which can increase the amount of oxygen and nutrients reaching the brain. This, in turn, can help reduce stress and anxiety, two common culprits of insomnia.

“Using a heating pad before bed can help create a more comfortable sleeping environment. Many people think that a cool room is ideal for sleep, but when it’s too cold, it can be difficult to relax and drift off. By using a heating pad, you can warm your body and make it easier to fall asleep.”
