Fact Sheet

The effects of chronic sleep loss are:
• Delayed reactions
• Easily distracted
• Forgetting known facts
• Difficulty remembering
• Making mistakes and omissions

Sleep loss leads you to be more stressed and irritable. It also leads to a drop in motivation.

The minimum amount of tolerated sleep is six hours. If this is maintained over several weeks your effectiveness slowly decreases. If you wanted to get your body used to just six hours sleep, it would take several weeks for your performance to not be effected. Just remember, even though your performance will not be affected, you will still continue to be drowsy. On the other hand don’t go and increase your sleep by 2-3 hours, as this also decreases performance.
In a sample of 1 million people conducted over six years, the lowest mortality rate was found in people who had on average 6.5 to 7.5 hours sleep a night. Too short or long a sleep has been found to correlate with an increase in diabetes and blood pressure.

A very important thing to note, is that just one night of sleeplessness can cause a 23% increase in mistakes, and a 14% increase in time taken when undertaking menial tasks.

Parents

In teenagers 8-15 who lacked sleep, it has been found they gain more weight than 3-8 year olds who also lacked sleep. The proposed reason for this, is that teenagers go to bed later and wake up later, whereas children go to bed earlier and wake up earlier.
