Approximately 1.2 million Australians suffer from a sleep disorder and with that, many are sleeping less than the 7-9 hours of recommended sleep for optimal functioning.
A lack of sleep can cause numerous problems including poor concentration, fatigue and poor judgment. Sleep disorders account for 9.1 percent of work related injuries. Sleep is important not only for the rest and rejuvenation of the body and mind, but it can also improve certain aspects of functioning. For example, getting adequate sleep can lead to improvements in memory and recall. When you are awake, you are constantly learning and remembering new information. Sleep is important for storing this new information, and whether the information is worth keeping in the memory bank. Adequate sleep allows for quicker recall of the new information as well as being able to use the new information.
Poor sleep has also been linked to weight gain. Those who sleep less than 4 to 5 hours were more likely to gain more weight than those who sleep more than 5 hours. Sleep deprived individuals tend to burn more calories and tend to eat more to compensate. Research has shown that those lacking sleep also choose fatty and high carbohydrate food- usually because it’s a quick and easy alternative. There is also links between the increased production of cortisol and weight gain due to a lack of sleep. High levels of cortisol can increase appetite and can also contribute to weight gain.
