What Is Melatonin and How Does It Work? (ADHD & Sleep)

If you're struggling with sleep and have ADHD, you're not alone. Sleep issues can significantly impact your daily life, mood and overall wellbeing.

This comprehensive guide will help you understand melatonin, how it specifically benefits ADHD-related sleep challenges, important safety considerations, guidance tailored to the UK and practical strategies to improve your sleep and increase your quality of life.

Firstly, what is Melatonin?

Melatonin is a hormone naturally produced by the pineal gland in your brain, primarily responsible for regulating your sleep-wake cycles, known as circadian rhythms. Typically, melatonin levels increase in the evening, peak overnight and decrease by morning. Modern lifestyles, such as excessive screen time and irregular sleep patterns, often disrupt this natural production cycle.

How Melatonin works

Darkness triggers your brain to release melatonin, signalling your body to prepare for sleep. Conversely, exposure to bright light or screen devices suppresses melatonin production, causing difficulties falling asleep and disruptions to the sleep cycle.

Melatonin’s role in ADHD

Sleep problems are common among individuals with ADHD due to factors like hyperactivity, anxiety, medication side effects, or inherent neurological differences. ADHD often involves an imbalance of neurotransmitters like dopamine, which can significantly affect sleep quality.

Research indicates that melatonin supplements can effectively help people with ADHD establish healthier sleep patterns, thereby improving attention, mood regulation, emotional resilience and overall daily functioning.

Melatonin dosages and recommendations

Melatonin dosage should always be tailored individually based on age, body weight, severity of sleep disruption and personal response:

• Children (6–12 years): Begin with 0.5mg–1mg approximately 30–60 minutes before bedtime.
• Adolescents (13–17 years): Typically recommended doses range from 1–3mg.
• Adults: Usually 2–5mg, often starting with prolonged-release formulations to maintain sleep throughout the night.

Immediate-release melatonin is beneficial for those struggling to fall asleep quickly, while prolonged-release forms help maintain continuous sleep through the night.

Potential side effects and safety concerns

Melatonin is generally well-tolerated, but potential side effects include:

• Daytime drowsiness or fatigue
• Mild headaches
• Dizziness or nausea
• Vivid or unusual dreams

To minimise side effects, start with the lowest effective dose. Regular consultations with healthcare providers ensure safe dosage adjustments and effective management of side effects.

Melatonin interactions with medications & supplements

While melatonin generally has minimal interactions, it’s important to consult healthcare providers if you use other medications or supplements, particularly:

• ADHD medications (usually safe, but professional guidance recommended)
• Antidepressants or mood stabilisers
• Sedatives or benzodiazepines
• Blood pressure medications
• Additional sleep aids or herbal supplements

Melatonin prescription & availability in the UK

NHS prescription

Obtaining melatonin via the NHS typically involves referral to a specialist (paediatrician or psychiatrist). Waiting times for appointments can vary considerably, from several weeks to months.

Private prescription

Private healthcare providers, such as HealthHero, offer quicker access to assessments and prescriptions, usually within one to two weeks. Initial consultations typically cost between £200–£300, providing greater flexibility and reduced waiting times.

Alternative and complementary approaches

Enhance the effectiveness of melatonin by integrating these complementary strategies:

• Magnesium supplements: Helps calm the nervous system and supports deeper, more restful sleep.
• Mindfulness and relaxation techniques: Regular practice can significantly reduce anxiety and help quiet a restless mind at bedtime.
• Structured bedtime routines: Gentle stretching, reading, or warm baths help signal your body that it's time to unwind.

Myths and misconceptions about Melatonin

Myth: Melatonin use leads to dependency.Fact: Melatonin is non-habit-forming and users typically experience no dependency with proper medical oversight.

Myth: Melatonin negatively affects fertility or hormonal balance.Fact: Current research does not show significant hormonal disruptions when melatonin is used responsibly and monitored by professionals.

Myth: Melatonin effectiveness wears off quickly.Fact: Adjustments in dose or timing often restore effectiveness and melatonin remains beneficial long-term when combined with healthy sleep hygiene.

Practical sleep guide

Optimising your sleep environment and routines alongside melatonin usage maximises effectiveness:

• Consistency: Regular sleep and wake times are crucial.
• Environment: Keep your room cool, quiet and dark.
• Pre-sleep routine: Engage in relaxing activities before bed.
• Limiting screen time: Avoid exposure to screens at least an hour before bedtime.
• Dietary adjustments: Limit caffeine and sugary snacks in the evening; opt instead for protein-rich snacks.
• Weighted blankets: These can reduce anxiety and improve sleep quality significantly.

Special considerations

• Travel with Melatonin: Keep prescriptions clearly labelled and carry a letter from your doctor, especially when travelling internationally.
• Adjusting dosages: Discuss any required dosage adjustments during periods of heightened stress, exams, or significant life changes with your healthcare provider.
