With the discussion of burnout growing, it's not surprising that fast-food workers are among those facing increased stress and fatigue due to their jobs.

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

Here at ISS, we’re often on the road seeing clients. One thing we always pack is our exercise gear. Squeezing in a daily workout is a top priority, especially if we are overseas. We feel it helps with counteracting any jet lag we may have. And now, we have research to back us up!
The study involved examining exercise and melatonin levels in 101 participants for up to five and a half days. It was found that exercising at 0700 or between 1300 & 1600 advanced the body clock to an earlier time, and exercising between 1900 & 2200 delayed the body clock to a later time.
So if you’re looking to help minimise your jet lag, or even get yourself back in sync after a block of shift, get those running shoes on at those specified times!

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:
Things you can do to reduce the likelihood of fatigue in the workplace include:

The study showed that those who slept for less than six hours a night were 27 per cent more likely to have subclinical atherosclerosis than those who slept for an average of seven or eight hours a night. Disturbed and fragmented sleep also increased the risk of subclinical atherosclerosis by 34 per cent. Interestingly, those who sleep more than 8 hours a night also have an increased risk.
People who sleep less than seven hours a night also have an increased risk of heart disease, and this is true regardless of other factors that influence heart health, like age, weight, smoking and exercise habits
Not sleeping enough can also increase heart-related issues such as blood pressure and obesity.

There is a close relationship between mental health and sleep. Poor sleep can be both a symptom and a cause of mental health conditions such as anxiety and depression. Therefore living with a mental health condition can affect the quality and quantity of sleep, which in turn can have a negative impact on your mental health.
The vicious cycle of lack of sleep leads to one being tired throughout the day, making it difficult to cope with day-to-day life. The inability to cope lowers one’s self-esteem, increasing stress and again leading to lack of sleep.
Sleep disorders, such as insomnia, are often experienced by those suffering from mental health conditions. Insomniacs sleep less overall and do not spend adequate time in the deeper parts of sleep, including REM. The REM stage of sleep is a restorative part of our sleep cycle, providing emotional and cognitive benefits. REM sleep allows us to regulate our emotions, maintain our memory capability and make good judgments. Without REM sleep, we tend to be moodier & irrational, suffer from memory lapses and are more inclined to make poor decisions. It’s easy to see how important REM sleep is, particularly for those suffering from mental health conditions.
Selective serotonin reuptake inhibitors, or SSRIs, are a type of medication that is most commonly used to combat depression and anxiety and essentially increase serotonin in the brain. A recent study on those who take SSRIs has shown that the medication is more effective on people who are early risers compared to night owls. It is believed that night owls tend to have more irregular schedules and are also exposed to less light in the morning and more in the evening, resulting in out of sync circadian rhythms. SSRIs boost how the body clock responds to light. Therefore, irregular schedules and light exposure would make SSRIs less effective. Along with seeking professional medical support and making lifestyle changes, we would suggest ensuring morning natural light exposure where possible, as well as keeping a more consistent schedule where possible.
