Working out late in the day - Expert reveals sleep mistakes we're all making

A blissful and restorative night's slumber can leave you feeling as though you can take on the world. But not everyone is so lucky. In fact, as many as 70 per cent of Australians report they don't get enough sleep, as a result, their performance is affected. Australian sleep expert Dr Carmel Harrington said if you want the most restful night's sleep possible you need to make sure your body, and mind, is properly primed. From why you should avoid late-night workouts to which foods will keep you awake FEMAIL takes a look at the mistakes people make and some simple ways to overcome these.

Don't ignore your body's natural rhythms:

Sleeping and waking are part of our circadian rhythms - our biological clocks that regulate when we wake and when we sleep. Dr Harrington explained these clocks are set to a 24 hour cycle and each day they are reset through exposure to sunlight. With all things being equal we should be ready to fall asleep 16 hours after we first 'set' our internal clock,' she said. However, as people are working longer hours, and in artificial light, this can play havoc with our natural cycle and tip things out of balance. .

I had four different pairs of glasses,’ she remembers as we chat over champagne at her agent’s North London apartment. I’d have one pair of glasses for looking; one for reading and then two pair of prescription sunglasses. It was ridiculous. My eyes got worse over the years. I’ve got about 50 pairs.’But now, having just undergone a pioneering lens exchange operation replacing her natural lenses with sophisticated trifocal implants – Samantha couldn’t be happier.She struggled with her eyesight since childhood and by the age of 15 was wearing glasses full-time. Then, at 16, she became the youngest-ever Page Three girl. Her buxom body (all natural she insists) was plastered over newspapers, billboards, television and even Playboy magazine before she retired from modelling after just four years to launch a music career. Glasses were not part of the image and she’d never got on with contact lenses..
