Elle MacPherson uses a $1,400 infrared ‘sauna suit’ in a bid to ‘promote her overall health’

She is one of the most glamorous and well-known supermodels in the world.

And on Monday, Elle Macpherson revealed one of the secrets behind her incredible figure.

The 56-year-old shared a photo to Instagram of herself using a $1400 infrared sauna and went on to tout the health benefits of the technology.

‘My version of wake and bake,’ Elle captioned the post.

‘Stacking my Biohacks for optimal health. I’ve also noticed the following benefits of the Thera360 Plus in my experience.’

‘Detoxification, decrease inflammation, relieve pain, burn calories, sleep better, anti-aging benefits and immune enhancement,’ she listed.

According to Therasage’s website, the $1,400 (AUD) sauna ‘enhances cell energy and blood circulation, relieves pain and burns calories’.

This is not the first time Elle has shared her body secrets as last year she offered fans a look at her wellness regime.

The mother-of-two revealed how she transformed her body by adopting an alkaline diet approach.

‘The incredible Dr Simone Lauscher introduced me to a plant-based diet and explained the importance of having an alkaline body and dietary approach,’ she told Rosie Huntington-Whiteley in a podcast.

The alkaline diet is based on the idea that replacing acid-forming foods with alkaline foods can improve your health.

Its premise is that your diet can alter the pH value – the measurement of acidity or alkalinity – of your body.

For Elle, it meant replacing acidic foods and drinks like meat, poultry, fish, eggs, grains and alcohol with fruits, nuts, legumes, and vegetables.
