A model claims she knows the secret to eternal youth – and it’s a lot cheaper than you think.

Nita Marie, 45, ensures she has at least one orgasm every day, which she says helps her look young and also aids her mental health.

Nita, who lives in Colorado, is urging others to follow her lead, and give themselves – or their partner – an orgasm every day.

She’s revealed her top tips for making sure you can get some “me time” into your daily schedule.

Nita Marie said: “September is self-care awareness month and I truly believe that everyone should try to have at least one orgasm a day.

“You should make it part of your self-care routine.

“There have been numerous scientific studies that show the natural hormone released during sex – oxytocin, also known as the love hormone – has many physical and psychological benefits.”

She added even if you don’t have a partner, Nita recommends you “pleasure yourself so you can experience the Big O.”

Nita Marie claims there are several health benefits of having regular orgasms.

1) A great night’s sleep

Nita Marie reckons regular climaxing helps her drift off at night and puts her into a deeper sleep.

When you experience orgasm, your body releases a hormone called oxytocin, which is sometimes referred to as “the love hormone.”

It’s thought that oxytocin can be used to treat anxiety and depression, as well as intestinal problems, because it creates an overall feeling of relaxation.

Nita Marie said: “Ever wondered why men just roll over and go to sleep after sex? It’s our body’s natural reaction and the more you do the more relaxed you will be.

“Since upping the amount and quality of my orgasms I’ve never slept better. It’s great for clearing your mind at the end of the day and switching off ready for sleep.”

2) Youthful looks

The model, who claims to make £722,000 ($1 million) from her looks every year, has to take good care of her looks – and claims orgasms are the secret to her youthful appearance.

She said: “Orgasms really do make you look younger.

“When you climax HGH – human growth hormone – is released, which helps to produce collagen in your skin for a younger and more youthful look.”

3) Regular periods

Some studies have suggested women who climax regularly are more likely to have a regular menstrual cycle.

It’s thought this is due to the blood and nutrients flowing towards the vagina during masturbation.

Nita Marie also reckons regular orgasms can help alleviate her period pains.

The model explained: “I’m always hornier during my period and the release of the orgasm really helps with my cramps.”

4) Sharper brain functions

Nita Marie reckons climaxing regularly helps her mind stay sharp – and she’s not the only one.

An experiment that saw women masturbating in an MRI machine to see what happened in their brains during climax showed an increased brain function.

The model said: “After I’ve climaxed I always feel like my brain has had a good spring clean, especially in the morning.

“Afterwards I feel like I’m really ready to start the day and concentrate on everything I need to – it’s better than any coffee for waking me up!”

5) Mental health benefits

When oxytocin is released during climax, it can have a really positive impact on our mood.

In 2017, researchers at Florida State University studied more than 200 newlywed couples and found the “afterglow” of feeling satisfied and stimulated after sex can last for up to two days.

Nita Marie said: “Whether I’m climaxing on my own or with my partner, enjoying that level of intimacy and pleasure has such a good effect on my mood and mental health.

“Knowing how it makes me feel, I try to always incorporate it into my self-care routine.”
