Sleep Health

An A to ZZZ guide to better sleep performance in 2023


This time of year, many people are setting new year goals for themselves, such as getting in shape and eating better. But did you know that spending time on rest and recovery is as critical to your health as diet and exercise?

Sleep is essential to our overall health, helping to restore our minds and bodies and keep them in peak performance. Specific benefits include cell and tissue repair, rest for your heart, as well as immune system strengthening.1

While you might be making gains in the gym, a lack of sleep can hinder your athletic performance by:2

  • Making you more exhausted
  • Decreasing your reaction time
  • Increasing your risk of injury
  • Inhibiting your speed and accuracy
  • Lowering your immune resistance to illness

Signs that you may not be getting enough sleep include.3

  • Excessive daytime sleepiness
  • Irritability and/or mood changes
  • Difficult with focusing on tasks
  • Falling asleep easily and/or at inappropriate times

Having these symptoms above may suggest you’ve had a restless night. But if they happen regularly, they could point to a sleep disorder known as obstructive sleep apnea (OSA). People with OSA experience disrupted breathing while they sleep. 

If you have concerns about your sleep, it might be time to consult a doctor. In the meantime, help give yourself a ‘wakeover’ with these tips. Below is our A to ZZZ guide on how to sleep better.

Avoid screentime before bed

Putting away our devices and cutting our time in front of screens may help us get to sleep faster and stay asleep. Research tells us that bright screens before bed  can impact the hormone melatonin that makes you sleepy.   

Bedtime routine should be consistent

Having the same bedtime every night helps your body maintain its circadian rhythm. 

Chamomile tea as a natural sleep supplement

Chamomile has been used as a medicinal herb since Ancient Egyptian times. Many people now like to enjoy it in their tea. Chamomile is generally regarded as having sedative effects.4

Dim the light before bed

This will tell your body it’s time to sleep by releasing the sleep-inducing hormone melatonin5. If blinds or curtains to block the light won’t work for you, try an eye mask.

Eat well

A lack of nutrients, including calcium, magnesium, and vitamins A, C, D, E, and K, is linked to shorter sleep6. Try to incorporate fruit and vegetables and other healthy foods that are good for your overall health and well-being.

Fine-tune the room temperature

Aim for a room temperature between 16-20 degrees Celsius, which is optimal for sleep7

Get some light exposure

As soon as you wake, expose yourself to sunlight by opening the blinds or going outside. Exposure to sunlight will help keep your body clock in tune.8

Hydration is important

Drink plenty of water during the day. Being dehydrated can cause you to experience headaches and muscle cramps. This can create discomfort and may prevent you from getting good sleep.9 

Indulge in a warm shower or bath

A warm and relaxing shower or bath can help calm your body and mind to help ease you into sleep. 

Listen to music

Music can help boost good feelings and reduce stress hormones. Soothing songs set at around 60 to 80 beats per minute (BPM) can help you gently fall into a deep sleep. 10


If there are work worries or other stresses on your mind, there's no better way to forget them than to switch your focus to something else. 

No alcohol before bed

While alcohol may help you fall asleep faster, it can also cause sleep disruptions.11  You should avoid alcohol at least four hours before bed.12

Power naps are preferred

The ideal nap length is around 10 to 20 minutes. This is because it is long enough to help you feel refreshed, but not too long that you will feel drowsy13.  

Quit the caffeine

Caffeine keeps us alert by blocking sleep-inducing chemicals in the brain14. It is also believed to affect our circadian rhythm or body clock, making it harder to fall asleep15

Read a book

Reading is a great activity to help you wind down and relax before bed.

Select sleep boosting foods

Nuts, for instance, can be great to snack on as many varieties contain the sleep-regulating hormone melatonin.16

Take a break

Stress is a major factor keeping us awake at night. But sometimes, all you need to de-stress is to find a better work-life balance by regularly taking a break to unwind and unclutter your brain. 

Urinate before bed

Frequent night-time urination can affect your sleep. Limit your liquid intake at night and go to the toilet before bed to avoid waking up to use the toilet.

Work out

Exercise can help reduce daytime sleepiness and the time it takes to fall asleep.17 But it's also vital for everyday health.
