One of my key health principles is Sleep.
Adequate, good sleep is vital for our health, as it restores our bodies physically and mentally. It is essential to enable healing from disease and longevity.
Poor, insufficient sleep can be a major health risk leading to fatigue, poor concentration, memory, mood, impaired judgement and even correlates with many health issues such as obesity, heart disease, strokes, diabetes, cancer and other.
The hours of sleep needed vary according to age groups, but generally 7-9 hours is optimal.
A table of recommended hours can be found here: https://www.sleephealthfoundation.org.au/sleep-topics/how-much-sleep-do-you-really-need
TIPS FOR BETTER SLEEP
Patterns
Set a time pattern to go to bed (not too late) and to wake up – keeping it as regular as possible to enable your internal body clock’s sleep-wake rhythm to function properly.
Environment
Create a sleep-friendly bedroom: comfortable mattress and pillow, quiet, dark and slightly cool in temperature, with no TV or screens.
Screen time just before bed suppresses melatonin and delays the circadian clock keeping us more awake.
Wind down and relax
Prepare for sleep. Try not to bring your worries with you to bed. Let go of the busy activities: exercise, technology, eating etc. Instead relax by taking a hot bath/shower, listening to music, reading etc. Ideally dim the lighting as it prepares us for sleep.
Declutter the Mind
Stress can greatly impact sleep, leading to an elevation in stress hormones, namely cortisol, which further disrupts sleep. Having difficulty in going off to sleep is usually associated with too much anxiety/stress, compared to waking in the early hours which is usually associated with depressed mood. Hence quality of sleep reflects what is going on in your life.
Even when we wake in the early hours, stressing will only keep us awake for longer. Breathing and meditation exercises can clear the mental clutter that keeps us awake.
This is a good time to practice muscle relaxation and slow breathing. Techniques such as 4-7-8 breathing, can be beneficial: breath in for four counts, hold breath to the count of seven, and exhaling to the count of eight.
Exercise
Regular daily exercise has been proven to promote better sleep. As does increased daytime exposure to sunlight, and conversely reduced light exposure in the evening. Sunshine stimulates melatonin production and darkness stimulates its release from the pineal gland.
Foods
For many people it is essential to limit caffeine and alcohol as these can interfere with sleep.
Eating an early dinner rather than later, helps the body to digest, preparing for sleep.
Several foods have properties associated with promoting sleep such as
Cherries, Milk, Oats, Almonds, Walnuts (Melatonin)
Milk, Turkey, Cheese, Soy (Tryptophan)
Bananas, Almonds, Eggs, Spinach (Magnesium & Potassium)
Kiwi (Serotonin)
Herbs
Traditionally many herbs have been proven useful in helping to fall asleep and stay asleep longer. These include: Valerian, Hops, Chamomile, Lavender, Passionflower. Also a large range of Traditional Chinese and Ayurvedic Medicine herbs that can be beneficial.
Latest research has also shown the CBD Oil (Medicinal Cannabis) is beneficial for sleep.

Therapies
Research studies indicate that cognitive behavioural therapy (CBT) can be more effective than sleeping medication for treating chronic insomnia.
Meditation and calming techniques – various Sleep Apps are available.
If sleep problems persist, it would be beneficial to seek advice of an integrative GP or health professional.
