Sleep is one of the most important foundations of childhood health and development. It influences everything from brain development, learning and memory to immune function, emotional regulation, hormone production and physical growth.
Yet for many families, getting children to sleep can feel like an ongoing battle. Some children struggle to fall asleep, others wake repeatedly throughout the night, and some seem to wake at the crack of dawn regardless of how late they went to bed.
For parents of neurodivergent children, sleep difficulties can be particularly challenging. Children with ADHD and autism may experience difficulties settling, maintaining sleep, regulating their nervous systems and transitioning from daytime activities into bedtime.
From a naturopathic perspective, sleep is about much more than simply establishing a bedtime routine. It involves looking at the body's internal clock, nutritional status, nervous system, digestive health, environmental influences and overall wellbeing.
Understanding what may be interfering with your child's sleep is an important first step towards improving it.
Why is sleep so important for children?
Sleep is an active biological process during which the body and brain carry out essential restorative functions.
During sleep, children experience:
-
Brain development and neurological processing.
-
Memory consolidation and learning.
-
Regulation of hormones involved in growth and development.
-
Immune system support.
-
Tissue repair and physical recovery.
-
Emotional processing and regulation.
-
Restoration of energy and metabolic balance.
Inadequate or disrupted sleep can contribute to difficulties with concentration, attention, behaviour, mood and learning.
Interestingly, children who are overtired don't always appear sleepy. Some become hyperactive, impulsive, emotional or unusually energetic. This can be particularly confusing for parents of children with ADHD, where sleep deprivation may amplify existing challenges with attention and emotional regulation.
Understanding the body clock: Circadian rhythm
Our bodies operate according to an internal 24-hour biological clock known as the circadian rhythm. This internal clock helps regulate when we feel awake and alert and when we naturally become sleepy. It is influenced by environmental cues, particularly light and darkness.
During the day, exposure to natural light helps signal to the brain that it is time to be awake. As evening approaches and light levels decrease, the brain begins preparing for sleep by increasing the production of melatonin.
Melatonin is a hormone produced by the pineal gland that helps regulate the sleep-wake cycle. It signals to the body that nighttime has arrived.
For children, supporting a healthy circadian rhythm is one of the most important foundations of good sleep.
How can we support a healthy circadian rhythm?
-
Encourage natural sunlight exposure in the morning.
-
Get children outdoors during the day.
-
Maintain relatively consistent waking and bedtime schedules.
-
Dim household lighting as bedtime approaches.
-
Reduce bright artificial light and screens in the evening.
-
Keep bedrooms dark during sleep.
Morning sunlight is particularly helpful because it reinforces the body's internal clock and helps establish a more predictable sleep-wake rhythm.
Why do children struggle with sleep?
Sleep difficulties can have several contributing factors. Rather than assuming a child simply needs a stricter bedtime routine, it is worth exploring what may be happening physiologically.
1. Nervous system dysregulation
Some children find it difficult to transition from a busy, stimulating day into a relaxed state ready for sleep.
Their nervous system may remain in a heightened state of alertness, making it difficult to switch off. This can be particularly relevant for children with ADHD, autism, sensory processing differences and anxiety. A child may be physically exhausted but mentally unable to settle.
Signs can include:
-
Constant movement or restlessness at bedtime.
-
Difficulty stopping activities.
-
Racing thoughts.
-
Emotional outbursts when asked to go to bed.
-
Needing a parent nearby to settle.
Supporting nervous system regulation throughout the day, rather than just at bedtime, can be an important part of improving sleep.
2. Melatonin production and sleep timing
Melatonin is an important regulator of our sleep-wake cycle.
Some children experience delayed sleep timing, meaning their natural biological drive to sleep occurs later than their desired bedtime. This can be particularly relevant in children with ADHD and autism, where circadian rhythm differences and sleep difficulties are commonly reported.
Evening exposure to bright light, particularly light from screens, can also interfere with the body's natural melatonin rhythm. Supporting natural melatonin production begins with establishing healthy light exposure patterns throughout the day.
3. Nutritional deficiencies and dietary factors
Nutrition plays an important role in normal neurological function and sleep regulation.
Several nutrients are involved in processes associated with sleep.
Magnesium
Magnesium is involved in normal muscle and nervous system function. Inadequate intake can affect general health, although magnesium supplementation has not been established as a routine treatment for childhood insomnia.
Iron
Iron is essential for neurological development and dopamine metabolism.
Low iron stores can be associated with restless legs syndrome and periodic limb movement disorders, both of which can interfere with sleep.
Children experiencing restless sleep, frequent movement or uncomfortable sensations in their legs may benefit from medical assessment of iron status where clinically indicated.
Zinc
Zinc plays a role in neurological function, growth and development. Adequate intake is important for general health, although evidence that zinc supplementation directly improves childhood sleep is limited.
Tryptophan
Tryptophan is an essential amino acid obtained through food. It is a precursor to serotonin, which can subsequently be converted into melatonin.
Including adequate protein and a varied diet helps provide the building blocks needed for normal neurotransmitter production.
4. Blood sugar fluctuations
Long gaps between meals, inadequate food intake and inconsistent eating patterns can affect a child's energy levels and overall wellbeing.
From a naturopathic perspective, I like to explore whether children are eating enough throughout the day and whether their evening meal provides adequate protein, fibre and healthy fats. A balanced evening meal can help support nutritional adequacy and satiety overnight.
However, night waking should not automatically be attributed to low blood sugar, and routine bedtime snacks are not necessary for every child.
5. Gut health and digestive discomfort
The gut and brain communicate through a complex network of nerves, hormones and immune signalling pathways known as the gut-brain axis. Digestive discomfort can make it difficult for children to settle and remain asleep.
Things worth investigating include:
Children with neurodevelopmental differences may also experience feeding difficulties, restricted diets and gastrointestinal symptoms, which can indirectly affect sleep.
Supporting digestive health is an important part of looking at the whole child.
6. Environmental influences
Sometimes the reason a child struggles to sleep is much simpler than we think. Children can be particularly sensitive to their sleeping environment.
Consider:
-
Bedroom temperature.
-
Light entering through windows.
-
Household noise.
-
Uncomfortable bedding or clothing.
-
Sensory sensitivities to textures.
-
Pets or siblings disturbing sleep.
-
Excessive stimulation before bedtime.
For neurodivergent children, sensory preferences can be particularly important. Some children need complete darkness, while others feel more comfortable with a dim night light. Some prefer weighted bedding.
How can a naturopath support children's sleep?
A naturopathic approach looks at the child as a whole rather than simply trying to make them sleepy.
During a consultation, we may explore sleep patterns, dietary intake, digestive function, nervous system regulation, environmental factors and relevant medical history. The aim is to identify potential contributing factors and develop an individualised plan.
1. Individualised nutritional support
A nutritional assessment can help identify dietary gaps and potential deficiencies. Depending on the child's presentation, we may consider investigating iron status, vitamin D or other nutritional markers. We may also request a Hair Tissue Mineral Analysis if your child is scared to have a blood test.
Supplementation should be based on individual need, age-appropriate dosing and clinical assessment rather than routinely giving children multiple sleep supplements. What works for one child might not work for the next.
2. Herbal medicine
Certain herbs have traditionally been used to support relaxation and sleep.
Examples include:
-
Chamomile: Traditionally used as a calming herb.
-
Lemon balm: Traditionally used for nervous tension and relaxation.
-
Passionflower: Traditionally used for restlessness and nervous tension.
-
Lavender: Commonly used in aromatherapy for relaxation.
Any herbal treatment for a child should be individually assessed by a suitably qualified practitioner.
3. Supporting nervous system regulation
For children who struggle to switch off, we may need to consider what their nervous system has experienced throughout the day.
Some helpful strategies include:
-
Predictable daily routines.
-
Gentle movement and outdoor play.
-
Quiet activities before bedtime.
-
Breathing exercises.
-
Gentle massage where the child enjoys touch.
-
Reducing sensory overload.
-
Coloring in before bed
4. Investigating underlying health concerns
Persistent sleep difficulties should not automatically be treated as a behavioural or nutritional problem.
Depending on symptoms, further assessment may be needed for:
-
Iron deficiency.
-
Restless legs syndrome.
-
Obstructive sleep apnoea.
-
Enlarged tonsils or adenoids.
-
Allergies or asthma.
-
Reflux.
-
Chronic pain.
-
Medication-related sleep disruption.
A naturopath can help identify concerns that warrant referral to a GP or paediatrician.
Practical sleep hygiene tips for parents
Small, consistent changes can make a significant difference to children's sleep habits.
Morning
-
Open the curtains and encourage natural morning light.
-
Aim for outdoor activity.
-
Establish a relatively consistent wake-up time.
-
Provide a nourishing breakfast.
During the day
-
Encourage plenty of physical activity.
-
Provide regular meals and snacks appropriate to the child's needs.
-
Allow opportunities for outdoor play.
-
Avoid excessive late-afternoon stimulation if it affects settling.
-
Maintain predictable daily routines.
Evening
-
Keep dinner reasonably consistent and never too late.
-
Avoid caffeinated drinks, including cola and energy drinks.
-
Reduce bright household lighting.
-
Switch off screens approximately one hour before bedtime where practical.
-
Introduce calming activities such as reading, drawing, puzzles or coloring in.
-
Establish a predictable bedtime routine.
Bedroom
-
Keep the room dark, quiet and comfortably cool.
-
Consider blackout curtains if early morning light is disruptive.
-
Choose comfortable bedding and sleepwear.
-
Minimise unnecessary noise and distractions.
-
Accommodate individual sensory preferences.
How much sleep do children actually need?
Sleep requirements change as children grow.
General recommendations for total sleep in a 24-hour period, including naps where applicable, are:
-
1–2 years: 11–14 hours.
-
3–5 years: 10–13 hours.
-
6–12 years: 9–12 hours.
-
13–18 years: 8–10 hours.
These are general guidelines. Individual sleep needs vary, and sleep quality is just as important as duration.
As a naturopath, my goal is to look beyond the sleepless nights and understand what your child's body may be telling us. By supporting the foundations of health and addressing individual contributing factors, we can work towards healthier sleep habits and better wellbeing for the whole family.
