Fatigue Management System


The IHF FMS KIT contains highly effective, research-proven tools for managing fatigue.

These exploit blue and yellow tinted light to selectively influence melatonin production and promote or inhibit sleep in a safe and medication-free manner.

Simple, effective and especially useful for shift workers, the IHF FMS KIT will help you sleep better and for longer.

Blue light is great for keeping us awake and focused.

High energy blue light scatters through the atmosphere making the sky look blue, humans use blue light as an indicator that it’s day time, and we should be awake and aware.

Blue light is great when we want to be focused, because it helps suppresses the production of the sleep hormone melatonin, and keeps us awake.

During the daytime blue light naturally makes us more alert and active.

Blue light is bad for sleep!

Artificial light, computers, phones and tablets produce blue light, keeping us awake even if we want to sleep.

Exposing ourselves to blue light just before going to bed, can cause poor sleep patterns.

A study published in The Lancet Psychiatry found that people with disrupted sleep patterns were more likely to have depression or bipolar disorder.

The worst affected were described as those with “very poor sleep hygiene – people on their mobile phones at midnight."

Artificial light and shift work

The circadian clock is hardwired into you, it's your inner time piece and calendar, it helps you to fall asleep at the right time.

But working at night in artificial light and then expecting to fall asleep as soon your shift finishes, can throw this body clock out, causing fatigue and broken sleep patterns.

Fatigue has also been implicated in 20% of accidents on major roads and is said to cost the UK £115 - £240 million per year in terms of work accidents alone.

Blue light blocking glasses

These glasses reduce blue light entering the eye, increasing the production of melatonin.

For a great night’s sleep, pop the Active fatigue glasses on 30 minutes before the time you want to sleep and maintain your normal bedtime routine.

Anti-fatigue light

When you need to be fully focused. Wake up with the Fatigue Management System light.

The Fatigue Management System light aids alertness and increases wakefulness, helping you to focus.

  1. Use the light when waking for at least 30 min
  2. Use light when appropriate throughout a shift when sleepy
