Blue light is the higher energy, shorter wavelengths on the visible light spectrum. It occurs naturally, with the highest levels occurring during the middle of the day. Blue light is also emitted from devices such as smartphones, tablets and computers, and white-coloured LED lights.
So if it occurs naturally, blue light can't be that bad for us, right? Blue light is necessary to set and regulate our circadian rhythm, which is done so by photoreceptor cells in our eyes. Therefore, exposure to blue light during daytime hours is certainly a positive. We can also use exposure to blue light in the morning to advance our circadian rhythm, helping those who want to move their sleep to an earlier time - a great way to avoid jet lag!
But too much blue light exposure from our devices later on in the day and throughout the night can delay and disrupt our circadian rhythm, causing sleep disruptions and potential fatigue. Exposure to bright daylight outside may reduce the sensitivity of the circadian system to light exposure at night, but we still recommend to put your devices down before heading to bed, and perhaps relaxing with some tunes or a good book!For more information on blue light, contact us via

Fatigue can be a hidden risk in the workplace, costing businesses millions of dollars a year. According to the Sleep Health Foundation, it is estimated that 7.4 million Australian adults do not regularly get the sleep they need, resulting in productivity losses of $17.9 billion.
Lack of sleep significantly reduces productivity within the workplace through absenteeism, presenteeism and decreased engagement. This also increases the risk of errors and injury in the workplace.
Fatigue can impact those who:

A lot of us have been fatigued behind the wheel and battled to keep our focus on the road. We've relied on the usual tactics to try to keep ourselves awake including winding the windows down and belting out our best rendition of Madonna as it's blaring through the speakers (ok, maybe just some of us!). Nodding off, or experiencing microsleeps, is really the worst case scenario. But being fatigued while driving can be enough to impair you alone, without actually experiencing a microsleep.
Someone who is fatigued will often experience slower reaction times, reduced ability to concentrate and delays in interpreting information. Driving in this state could easily result in a traffic incident or accident.
The human body will naturally cycle through intervals of sleepiness and alertness, better known as the circadian rhythm. The window of circadian low (WOCL)
is a period between
To avoid driver fatigue, we recommend to:

The airline industry is a growing 24/7 operation, boasting an estimated 39 million flights to be flown worldwide by the end of 2018. Flying passengers across the country, or even across the globe, can create a variety of different challenges for cabin crew, including extended duty periods, highly variable schedules, possible frequent time zone changes, and increased passenger loads.
A study has shown a link between the job characteristics of cabin crew and fatigue. The graph below is an indication of the main work factors that contribute to fatigue amongst cabin crew workers, according to union representatives. Long hours and lack of rest are seen as the main offenders.
Other factors that may contribute to cabin crew fatigue include, but are not limited to:
In 2016, a bill was pass that requires airlines to provide cabin crew with a minimum 10-hour rest period between shifts, matching the requirement for pilots. The bill also included a requirement for cabin crew to be included in Fatigue Risk Management Systems, which until that point was only applied to pilots.
In Australia, there are currently no civil aviation regulations governing duty times and rest requirements for cabin crew. Their duty limitations are set contractually, and minimum standards are set by the country in which the cabin crew are employed. Cabin crew are our first responders to a safety event - is it time they are included in fatigue regulations?

Tired or fatigued employees can have a significant effect in the workplace, reducing productivity through personal days, reduced hours and a general decline in efficiency while working. The solution is simple, and no, it does not involve drinking copious amounts of coffee. Studies have shown napping to be quite beneficial, improving alertness and performance.
Workplaces around the world, such as some air traffic control organisations, have formalised a controlled napping procedure, where naps are built into a controller's daily schedule. The most beneficial nap we would recommend is one of 20-25 minutes in length, however, even a 10-minute power nap is enough to improve one's cognitive function and reaction time.
It is advisable to limit your naps to less than 30 minutes, in order to minimise sleep inertia - the period of impaired performance and grogginess experienced after waking - and allow yourself to wake up.
Join us in Singapore for our Fatigue Management & Human Factors in our 24-hour Society event in March 2019 to find out more about what the current
research tells us about naps. For more information on napping, contact us via
