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.

Bruxism is the medical term for grinding teeth and/or clenching one's jaw unconsciously. Grinding or clenching can occur both when awake or asleep. However, sleep bruxism is generally a more significant health concern.
Those with sleep bruxism may not know they’re grinding or clenching, meaning the disorder can easily be left untreated and can lead to broken or damaged teeth, headaches, jaw pain, and temporomandibular joint (TMJ) disorder. The constant tensing of muscles does not allow the body to relax, ultimately affecting sleep quality.
The exact causes of bruxism are unknown, but risk factors include:
Lifestyle modifications can help reduce symptoms and improve sleep quality for people experiencing bruxism. These include:
Dental devices such as occlusal guards and splits can also help prevent further damage to the teeth and jaw.

Back before the days of digital televisions or radios, you may remember quickly turning the volume down when that awful noise came blaring through the speakers, signifying there was no signal.
So, how is it that white noise can actually help us sleep?
White noise gets its name from ‘white light’ - all frequencies of colour in combination. White noise is a mix of every audible frequency at the same amplitude. The sound of white noise we hear as humans is the sound of all the frequencies between 20 and 20,000 Hz.
White noise can mask louder or unwanted noises such as traffic, housemates or neighbours, etc. The white noise will engage your brain, however, will not stimulate or arouse the brain, allowing one to relax and sleep.

For many of us, the end-of-year festive season is a busy time, catching up with friends and family, indulging in over-eating and attempting to get some much needed quality sleep! However, despite possibly sleeping more than usual, holidays can still leave you feeling tired. This is especially the case during the demanding festive season.
Aspects of the festive sleep that can affect your sleep include:
Additionally, with all the changes in sleep, alcohol and nutrition, the end of holidays marks the end of pleasant and enjoyable activities that would not usually be part of the average routine day. There could definitely be a link to how we spent our holidays, to how we cope with returning to work, and how quickly the benefits of holidays fade away.
