Fatigue Management

Our busy lives demand that we be ready for anything, 24/7. Whether it’s because our job requires us to always be alert and attentive, or because our family is depending on us, we need to feel positive, energetic and focused.

Fatigue is a common and often serious problem in the workplace. Truck Drivers, for example, often attempt to work 18-hour days, making fatigue inevitable. Highway crashes, including those involving cars, peak in the middle of the night when daily alertness is at its lowest. Many disasters, including the Chernobyl nuclear core meltdown and the Challenger disaster, occurred at night when operators were suffering from sleep loss.


Feeling Fatigued?

If you are feeling fatigued, you may experience:

  • Eyes go out of focus or close for a moment

  • Slowed, slurred speech

  • Blurred vision or seeing mirages ahead

  • Wandering and disconnected thoughts

  • Headaches or stomach aches

  • Drowsiness

  • Inattention to minor but potentially important details

  • Degraded mental abilities (including memory, decision-making, and perception)

  • Increased distractibility and irritability

  • Reluctance to initiate tasks and take command

  • Reduced sense of humor


How can I manage my fatigue?

  • In clinical studies, bright light exposure helps regulate sleep patterns by helping the body clock send signals to the rest of the body that morning has arrived and alertness is required.

  • While light exposure can never replace sleep, using The Litebook® for 15-30 minutes when fatigued may produce a similar energy-boosting effect as drinking a cup of coffee, without the side effects of dehydration and possibly caffeine addiction.

  • IMPORTANT: Bright light exposure should not be used to replace sleep or to promote sleep deprivation, as nothing can replace a deep, sufficient sleep.


General usage instructions:

  • The Litebook® should be positioned approximately 20-24 inches from your face, and should be offset at a 30 to 45 degree angle, like sunlight coming in a window.

  • For most applications, usage is once per day, on a daily basis.

  • Timing of light exposure is very important, and varies by your individual need.

  • The Litebook’s® light beam must be directed at your eyes, and your eyes must be open to achieve benefit.

  • The Litebook’s® light beam is very bright – like the sun – in order to provide the benefit you seek. You do not stare at The Litebook® – as you do not stare at the sun – although it is not harmful to glance at it occasionally.

  • Typically, you will recognize when you’ve received sufficient light – most often by feeling of heightened alertness, energy, and/or mood.
