According to a study conducted by the researchers of the Brain and Mind Research Institute, Sydney, the risk of developing depression and bipolar disease in teenagers depends on the way they sleep.

The lead researcher of the study, Naomi Rogers examined how teens having mood disorders frequently have disturbed circadian rhythms and irregular sleep-wake behavior.

The researchers believe that these disrupted sleep patterns can be a helpful clue for the parents to notice that their teenager is in trouble.

Sally Ferguson of University of South Australia says that sleeping fewer hours than required can adversely affect the performance at the workplace.

The study suggest that those shift workers who work for long hours and do not sleep adequately are at increased risk of committing mistakes at work and also more vulnerable to fatigue-related accidents.

Ferguson thinks that lack of sleep among shift workers and night workers is quite serious and their management should take proper steps to deal with this issue.

According to the study by John Wheatley of Ludwig Engel Centre for Respiratory Research, Sydney, heavy snoring is related to increased risk of stroke and cardiovascular disease.

A new cross-sectional study and laboratory test findings reveal that the vibrations due to heavy snoring could separately lead to vascular disease and causing the arteries to the brain to narrow.
