Sleep well while shift working
Why is sleep so important?
Did you know that night shift workers get on average 25-33% less sleep than regular nine-to-five workers? And they lose an average of 1.5 hours of sleep in every 24-hour period, meaning that over four days this is comparable to losing a whole night of sleep!
A lack of sleep can have negative effects on our health. It has been shown to promote weight gain, overeating and reduced physical activity, as well as increased feelings of stress, depression and irritability. It can also impair our cognitive function. This means our concentration, problem solving and decision-making skills may be reduced, impacting our ability to undertake work activities, as well as everyday life tasks.
It’s recommended that we obtain 7-9 hours of sleep each night for optimal health and functioning.
Shift work disorder
It’s estimated that 10-15% of shift workers experience shift work disorder. Shift work disorder is caused by a disruption to our internal body clocks – also known as our circadian rhythm – that arises as a result of working long hours and having a frequently changing schedule. It’s characterised by insomnia and feelings of extreme tiredness. Sufferers of shift work disorder commonly experience:
- Shortened sleep
- Trouble falling asleep
- Trouble staying asleep
- Constant fatigue and exhaustion
Why do shift workers struggle getting enough sleep?
It’s not surprising that poor sleep is the most frequently reported high-risk lifestyle behaviour among shift workers. Many shift workers have constantly changing work schedules making it difficult to establish and maintain a regular sleeping pattern. Other behaviours which may cause sleeping difficulties include:
- High intake of caffeine and/or sugar to stay awake and alert on shifts.
- Smoking. Similar to caffeine, nicotine is a stimulant which can keep you awake.
- Eating close to bedtime and in particular, eating fatty or spicy foods.
- Alcohol intake. It’s a common myth that alcohol assists sleep but rather it results in a more disruptive and reduced quality of sleep.
- Attempting to sleep in a bright room or when there is lots of background noise. This is common amongst night shift workers trying to sleep during daylight hours.
10 sleep tips for shift workers
Here are 10 tips to help improve your sleep as a shift worker.
- Engage in regular physical activity. Preferably be active every day and if not, on most days. The Australian Physical Activity Guidelines recommend engaging in 150-300 minutes (2.5-5 hrs) of moderate intensity or 75-150 minutes (1.25-2.5 hrs) of vigorous intensity physical activity a week.
- Instead of reaching for caffeine or sugar, try choosing foods high in protein and fibre to power through a night shift. For example, 99% fat-free plain yoghurt with fruit or nuts.
- Avoid eating large meals 2-3 hours before bed, particularly if they are spicy or high in fat.
- Avoid behaviours like smoking and alcohol. In particular, before bedtime to try and enhance the quality of your sleep.
- Try a relaxing activity before bed, such as reading a book, having a warm bath or shower, or drinking non-caffeinated tea such as camomile.
- Try some light stretching or yoga prior to bedtime. Consider trying the FitOn or Aaptiv bedtime stretches available on the WW app.
- Listen to a calming meditation.
- Limit exposure to bright light and electronic devices an hour before bed.
- If trying to sleep during the day, use an eye mask to block out light, or invest in blackout blinds or curtains to reduce natural sunlight.
- If stress and worries keep you awake, it may be helpful to relieve these by writing them down in a journal an hour before bedtime.
Tip from WW Coach Abby
“Have a half an hour bedtime routine – even if it’s in the middle of the day! If you follow that same routine, your body will recognise that it’s time for sleep.”
How to use the WW app sleep feature
The sleep feature can be found on the ‘My Day’ screen of the WW app, under the card titled ‘Sleep’. Here there are some tools to assist WW members in optimising their sleep. These include:
1. Sleep tracker
Each morning after you wake up, simply tap on the Sleep card on the ‘My Day’ screen, then tap “Track sleep”. Input what time you went to bed, what time you woke up, how much you were awake in the night and how you feel this morning. We do recommend that you track your sleep within an hour of waking up, while it’s still fresh in your mind. After you submit your data, we'll show you what your sleep average has been for the past week, and how many days you hit the recommended 7-9 hours of sleep a night! If you slept 7-9 hours a blue dot will appear.
You can also sync your device that tracks sleep to the WW app, so your sleep data automatically appears. To connect your device to track your sleep, you can tap the “Connect device or app” button on the Sleep dashboard. Alternatively, you can go to Settings > Activity / Sleep settings > Device > select your device.
By tracking your sleep patterns, you are able to achieve a greater understanding of what works and what doesn’t, giving you the ability to make changes that improve your sleep.
2. Stretches and meditations
To relax your body and mind for better sleep, this section of the sleep feature offers you a range of stretches, meditations and sleep music. Try using these before bedtime to help you relax and ease you into a restful sleep.
