Heather Graham sleeps up to 12 HOURS a night to maintain an ageless physique

Heather Graham stunned fans earlier this week after she posed in a white bikini at the age of 53 – and the snaps left many wondering how she achieved such an enviable physique.

In the recent images, shared on Instagram on Tuesday, the Boogie Nights actress showed off her summer-ready figure as she frolicked on the beach for a photo shoot in Jamaica.

The On A Wing And A Prayer star made an impact in the two-piece that highlighted her toned midriff and long legs as she splashed around in the water.

And the age-defying blonde beauty left her 469,000 followers mesmerized by how good she looked.

It would be true to say that Heather’s diet and exercise regimens are versatile.

But her “obsession” with yoga, sugar-free diet and up to 12 hours of sleep a night have all played a part in her youthful appearance.

Here, FEMAIL takes a look at how Heather has maintained such a gorgeous bikini body at age 53.

The Hangover star is not one to shy away from an active lifestyle and thrives on an exercise regimen that includes yoga, Pilates and pole dancing

First and foremost, Heather’s enviable physique can be largely attributed to her very active lifestyle, which includes regular bike rides and walks.

“I’m obsessed with yoga,” she also shared Refinery29 earlier.

“For fun, I went on a yoga retreat and did four hours of yoga a day. Then I do Pilates.’

And she often flaunts her flexibility in countless snapshots of exotic destinations.

The energetic star is also a big fan of dancing and revealed her bizarre guilty pleasure during an appearance on Late night with Conan O’Brien.

Heather asked the presenter, “Do you ever go into your house alone at night, turn off all the lights, turn on your favorite song and just dance around like crazy?” It’s so much fun.’

In discussing some of the songs she likes to get down to, she referenced Gnarls Barkley’s Crazy and Rihanna’s Umbrella.

She also revealed tthat a friend taught her pole dancing, which is known to help build core and upper body strength.

But Heather always finds time to kick back and relax spend 20 minutes a day in transcendental meditation – a non-religious method for relaxation, stress relief and self-development.

The Hangover star was reportedly introduced to the practice by director David Lynch when she made the Twin Peaks prequel Fire Walk With Me in 1992 — and she hasn’t looked back since.

The actress can also credit her diet for her flawless figure in which she avoids sugar, white flour and alcohol

Another of Heather’s beauty secrets is undoubtedly her diet.

The star on the screen previously mentioned how she sticks to a sugar-free diet whenever possible.

She told Refinery 29, “I’ve become one of those obnoxious people who say, ‘I’m not going to eat white flour and I’m not going to eat sugar.’

“I do eat sugar sometimes, but generally I just try not to eat sugar, and I have to say I feel a lot better.

“And I sometimes eat things with white flour, but I try to avoid white flour.”

She revealed that one of her favorite foods is beer canned chicken with sweet potato wedges, which she bakes instead of fries to make them healthier.

The Hangover star also said, “I make a really good salad with kale, chopped raw Brussels sprouts, and toasted almonds.” Everyone loves kale. It does make you feel healthy.’

Similarly, the actress told The independent in 2013 that she had largely stopped consuming alcohol, adding, “I’m kind of goofy enough to have fun without drinking.”

Heather said people are often ‘shocked’ after finding out how much she sleeps — and she’ll definitely prioritize self-care

As with many A-listers, Heather has often attributed her youthful face to getting enough sleep.

She told before The protector that getting a serious wink of sleep was her guilty pleasure as she revealed, “I like sleeping.”

‘When I tell people how much I sleep sometimes, they startle. I actually sleep between nine and twelve hours a night.’

Sleep is often considered a natural way to fight signs of aging, such as wrinkles and sagging, because it stimulates the production of new collagen.

Heather also liked to emphasize that she “spends a wonderful day in bed” once a week.

But it’s not the only form of self-care she actively encourages.

Previously asked how she keeps her skin looking so youthful, Heather told Refinery 29, “I really like moisturizing — my whole body, my face. I use this cheap Body Shop Nourishing Night Cream, and sometimes I use Crème de la Mer.”

Elsewhere she also mentioned that she will often get massages too, telling The Independent: ‘I try to pamper myself because life is too short.

“When I was a kid I used to think, ‘Oh, people who get massages are so wasteful. Why are they wasting money on something you don’t need?’

‘Now I think: “You could die tomorrow, you should just spend that money on a massage.”

‘I’m getting better at doing nice things for myself.’
