If you are like many Canadians, you’re getting less than six hours of sleep per night. The cumulative health consequences of sleep deprivation are severe – including increased risk of hypertension, diabetes, obesity, depression, heart attack, and stroke. Sleep deprivation negatively impacts the whole body, but no one organ is as severely affected as the brain.
Recent reports suggest that about 1 in 3 Canadians are chronically sleep deprived including adolescence and children, making Canada the 3rd most sleep deprived country on the planet! Not only is sleep deprivation having a devastating impact on our health, some report suggests that sleep deprivation is also costing the Canadian economy about $21.4 billion (USD) per year due to lost employee productivity.
Some of the impacts of poor sleep:
Slowed reaction time
Sleep-deprived individuals are at a greater risk of car accidents, other accidents and general injury due to a reduced ability to respond quickly to stimuli. Lack of sleep can also impair visual reaction time and delay auditory reaction.
Lower cognitive performance
Sleep deprivation causes a decrease in alertness and attention, negatively impacting our decision-making capabilities.
Depression has been linked to chronic sleep deficiency. Repeated moderate-intensity exercise may improve mood shortly afterwards, but without proper sleep on a regular mood disturbances, lower energy levels and fatigue can persist.
Longer recovery time post injury
Post-injury recovery is adversely impacted by chronic sleep deprivation.
Be aware of how your sleep levels are impacting you and make adjustments if you are not reaching the necessary seven to nine hours per night.
