It seems the stress of the jet-set supermodel lifestyle is taking a toll on Kendall Jenner.

In a new preview of Keeping Up With The Kardashians, she indicates she is suffering from sleep paralysis.

'I wake up in the middle of the night and I can't move,' she says.

The episode of the reality series was filmed in the lead up to the Milan, Paris and London Fashion Weeks this year. She was absent from the catwalk fixture in all three cities.

As the promo E! have released wore on, a brief clip showed her modelling a floral crop top and a forlorn expression in front of a blue screen.

She then appeared lounging on her couch, showcasing her legs from beneath a white bathrobe.

Her iPhone was in her hand, set to speakerphone, and her mother Kris Jenner's voice emerged from it, saying: 'I think you've just got anxiety.'

Kendall insisted: 'Everyone says I'm fine, but I don't feel fine.'

In a teaser for the show which aired earlier this month, Kendall was seen hitting out at her family for not taking her health worries seriously enough.

She fumed: 'I'm done arguing with people because I don't feel fine.

'I promise one day when I'm rushed to the hospital, then you guys are going to wake up.'

Sufferes of sleep parayslis can't move their arms and legs, body, and head when falling asleep or waking up. Episodes last from only seconds to a few minutes, according to the American Academy of Sleep Medicine.

Lack of sleep and a sleep schedule that often changes can be a factor.

Last December, Kendall revealed she had been hospitalised due to exhaustion, and admitted her health scare had made her vow to look after herself better.

Shortly thereafter, she discussed the incident on her blog, calling it 'definitely a wake-up call that I need to take better care of myself' and adding: 'I want to enjoy being home a little bit more.'

She admitted: 'Honestly, I worked so much this year that it freaked me out a little. So, I guess my resolution would be to chill out more and have the ability to be a little more spontaneous.'

Yet she took pains to clarify: 'It's not even about FOMO, because I've made so many good friends who work in the same industry. It's not about missing them; it's more that I just got so tired from work and life and everything that it freaked me out at the end of this year.'
