Wake up!

Dedicated to keeping people awake, the London based AWAKE has developed a formula which will calculate when a person will be the most tired.

Scientists have devised a formula that can tell the 12 million Britons who struggle to stay awake at work when to expect a daytime "dip" - and also when they are most likely to feel alert.

The formula, produced by the fatigue-management consultancy Awake, is based on circadian rhythms - the 24-hour biological clock that determines our sleeping and waking cycles.

Awake arrived at the equation CDA+CT+KF=TMT, where CDA stands for "circadian dip in alertness", CT for "chronotype" - the timing of an individual's body clock - and KF for "knacker factors" such as prior sleep quality and quantity, and alcohol consumption. TMT is the time a person is likely to feel "most tired".

Dr Paul Jackson, managing director of Awake, said "This simple equation enables anyone to calculate what time of the day they are likely to feel most tired and schedule their activities accordingly." Source.
