More than one in three Australians don’t reach the recommended seven to eight hours of sleep each night, with 85 per cent waking up to three times during the night.2

According to GenesisCare Respiratory and Sleep medicine physician, Dr Scott Claxton, Perth, sleep deprivation can have serious short and long-term effects on our overall health.

Alarmingly, after 24 hours of no sleep, hand-to-eye coordination is similar to having a blood alcohol content of 0.1, increasing risk of road accidents or workplace injuries.

Other short terms effects of sleep deprivation can include:

  • Memory loss
  • Anxiety
  • Reduced concentration

In the long-term, sleep deprivation can lead to:

  • Early ageing
  • Alzheimer’s Diseases
  • Higher rates of heart disease
  • Obesity
  • Higher rates of cancer

According to Dr Claxton, good sleep hygiene can help to ensure a restful night’s sleep.
