In turn acting as a potential preventive for a range of many chronic diseases that affect millions of people today. Artificial light can prolong and degrees the body’s ability to create melatonin (the sleep hormone) this can be devastating to our health. Lack of sleep has been proven and linked to a range of illnesses with long term effects not to mention lack of sleep can have the same affects as alcohol when it comes to the simplest tasks like driving. 6 hours of sleep every night = same performance as someone legally drunk reading 0.08 – 0.1 which is over the legal Australian limit. 40% of Australians suffer from Inadequate sleep and I.S. is becoming a chronic issue.
