Why sleep health matters
Body Focused

Cognitive performance

During sleep, your brain processes and organises the events of the day, consolidating memories and enhancing your ability to learn and focus. Chronic sleep deprivation disrupts these processes, making it harder to concentrate, problem-solve, and retain information. Many clients describe feeling ‘foggy’ or scattered when they’re not sleeping well – a common sign that the brain hasn’t had the chance to reset.

Emotional resilience

Sleep is your emotional regulator, giving your brain space to process stress and emotions. When rest is insufficient, feelings of anxiety, irritability, or overwhelm can intensify. It can lead to a vicious cycle where stress feeds poor sleep, and poor sleep magnifies stress, leaving you stuck in emotional overdrive.

Long-term impact

Chronic sleep difficulties are associated with significant health risks, including depression, anxiety, diabetes, and cardiovascular disease. From a therapeutic perspective, understanding how sleep ties into these conditions helps us work together to prevent or manage them, offering a path toward a healthier, more balanced life.

Signs You May Need Sleep Therapy

There are many reasons to seek help with your sleep issues that include:

Struggling to fall asleep or stay asleep consistently, leaving you restless most nights.

You are waking up feeling persistently fatigued, even after what seems like a full night's sleep.

You feel that stress or anxiety regularly disrupts your ability to rest peacefully.

You experience irregular sleep patterns that interfere with your daily routine and overall wellbeing.

Battle with night-time worries or recurring nightmares that disturb your sleep.

Seeking professional support can make a significant difference in your quality of life. If any of these challenges resonate with you, consider booking an initial consultation to receive a comprehensive assessment and a personalised plan to restore your sleep.

A Holistic & Relational Approach to Sleep Therapy

Heather brings a relational lens to sleep therapy, recognising that your experiences with rest are deeply shaped by connections – with yourself, with others, and with the world around you. She believes that sleep challenges often hold a mirror to the patterns, stresses, and relational dynamics in your life, and her work focuses on understanding these complexities in a compassionate and collaborative way.

Every step of your journey – starting with a detailed two-hour initial consultation and continuing with focused 50-minute follow-up sessions – is designed to reflect this holistic, relational approach, ensuring your unique sleep challenges are addressed with personalised care.

Taking A Relational Approach To Improving Sleep
Heather’s Approach Integrates

Heather’s approach integrates evidence-based practices, such as mindfulness and cognitive-behavioural strategies, with a deep exploration of the emotional and relational factors that may be impacting sleep. By considering how past experiences, current relationships, and lifestyle habits intersect, she creates a tailored plan that addresses not only the symptoms but also the underlying causes of sleep difficulties.

Her goal is to foster a sense of safety and trust, empowering clients to rebuild their relationship with sleep as a nurturing, restorative part of life. Through a comprehensive two-hour initial consultation and focused 50-minute follow-up sessions, Heather supports her clients in achieving better sleep while cultivating deeper self-awareness and more fulfilling connections for lasting growth and transformation.

Areas of support at the Sleep Clinic

Heather works collaboratively with you and, when needed, other clinicians you may be seeing, to address a range of sleep-related challenges by focusing on the underlying factors and patterns contributing to disrupted sleep. While diagnoses and treatments are managed by medical colleagues, Heather provides therapeutic support for:
Insomnia: Persistent difficulties with falling or staying asleep, often linked to stress, anxiety, or situations beyond your control.
Disrupted sleep patterns including circadian rhythm disorders: Irregular sleep-wake cycles that interfere with daily life, often influenced by biological, lifestyle, or environmental factors.
Sleep deprivation: The impact of chronic insufficient rest, leading to physical fatigue, emotional exhaustion, and diminished wellbeing.
Night-time worry: Restlessness or anxiety at night that makes it difficult to relax and drift into restful sleep.
ADHD and sleep: Helping those with ADHD navigate challenges such as restlessness, irregular sleep patterns, and night-time hyperactivity.
Stress-related sleep difficulties: Difficulties with falling or staying asleep due to the effects of heightened stress on the mind and body.
Weight issues and sleep: Supporting individuals managing weight-related concerns—including those addressing sleep apnea—by exploring the emotional and behavioural patterns that impact sleep and overall wellbeing.

All of these areas of support are delivered through a personalized, structured approach that begins with a comprehensive two-hour initial consultation, followed by regular 50-minute sessions—available both online and in-person—to meet your unique sleep needs.

Heather’s speciality lies in exploring the deeper issues that often sit beneath the surface of sleep difficulties. Many of her clients find that this work opens the door to greater self-understanding—often beginning with a comprehensive two-hour consultation followed by focused 50-minute sessions—and choose to engage in longer-term psychotherapy to address broader patterns and experiences influencing their lives.
