About melatonin

Melatonin is a natural hormone produced by the brain’s pineal gland that plays a crucial role in regulating the sleep-wake cycle. Its production is influenced by the body’s internal clock, with levels rising in the evening to promote relaxation and sleep, and decreasing in the morning to encourage wakefulness. Melatonin release is triggered by darkness, while exposure to bright light, especially from screens, can suppress its production, making it harder to fall asleep. Factors such as excessive screen time, high stress levels, aging, shift work, and irregular sleep schedules can disrupt melatonin production, leading to sleep disturbances like insomnia. Maintaining a consistent sleep routine, reducing blue light exposure before bed, and managing stress can naturally support healthy melatonin levels and improve sleep quality. Consult a health care professional if you have persistent issues with sleep.

    When to consult a doctor for melatonin treatment?

    A GP can assess your sleep concerns, recommend appropriate melatonin treatment, and provide guidance on dosage and duration. You should consider consulting a GP for melatonin treatment if you experience:

    • Persistent sleep issues: Difficulty falling or staying asleep despite good sleep hygiene.
    • Jet lag or shift work disorder: Trouble adjusting to new time zones or irregular work hours.
    • Delayed sleep phase syndrome (DSPS): A natural tendency to fall asleep very late and wake up late.
    • Sleep disturbances: Difficulty sleeping caused by mental health conditions such as anxiety and depression.
    • Chronic insomnia: Ongoing sleep difficulties affecting daily life and well-being.
    • Concerns about melatonin use: If you’re unsure about the right dosage, potential interactions, or long-term effects.

    What are the common symptoms of melatonin deficiency?

    Melatonin deficiency can disrupt sleep and impact overall well-being. Some common symptoms include:

    • Difficulty falling asleep: Trouble initiating sleep or experiencing insomnia.
    • Frequent night wakings: Waking up multiple times during the night and struggling to fall back asleep.
    • Daytime fatigue: Feeling tired, sluggish, or lacking energy throughout the day.
    • Mood changes: Increased stress, irritability, anxiety, or symptoms of depression.
    • Weakened immune system: More frequent illnesses due to reduced immune function.
    • Cognitive issues: Trouble focusing, memory lapses, or brain fog.

    What are the causes for melatonin deficiency?

    Melatonin deficiency can result from various factors, including:

    • Excessive screen time: Blue light from phones, tablets, and computers suppresses melatonin production.
    • Irregular sleep schedule: Shift work, jet lag, or inconsistent bedtime routines can disrupt melatonin levels.
    • Chronic stress: High cortisol levels interfere with melatonin production.
    • Aging: Natural melatonin levels decline with age, leading to sleep disturbances.
    • Poor diet: Deficiencies in magnesium, zinc, or tryptophan (an amino acid needed for melatonin production) can contribute.
    • Caffeine & alcohol consumption: Both can suppress melatonin release and disrupt sleep patterns.

    How to manage melatonin?

    To restore healthy melatonin levels, consider the following:

    • Reduce blue light exposure: Avoid screens at least an hour before bedtime or use blue-light-blocking glasses.
    • Maintain a consistent sleep schedule: Go to bed and wake up at the same time daily, even on weekends.
    • Manage stress: Practice relaxation techniques like meditation, deep breathing, or yoga.
    • Create a dark sleeping environment: Use blackout curtains and limit artificial light at night.
    • Improve diet: Eat melatonin-boosting foods like nuts, cherries, bananas, and dairy.
    • Consult a doctor: If lifestyle changes aren’t enough, consult a doctor about melatonin

    What happens if I have too little melatonin?

    Melatonin deficiency can lead to difficulty falling asleep, frequent nighttime awakenings, daytime fatigue, poor concentration, and a weakened immune system. Long-term deficiency may contribute to anxiety, depression, and metabolic issues.

    What are natural ways to boost melatonin levels?

    Exposure to natural light during the day, reducing screen time before bed, maintaining a regular sleep schedule, and eating melatonin-rich foods (such as cherries, nuts, and dairy) can help increase melatonin production naturally.

    What happens if I have too much melatonin?

    Excessive melatonin can cause drowsiness, headaches, dizziness, nausea, and disruptions in your sleep-wake cycle. Overuse may also lead to hormonal imbalances, mood changes, and digestive issues.

    How much sleep do I need?

    The amount of sleep you need depends on your age, lifestyle, and overall health. The general recommendations are:

    • Newborns (0-3 months): 14-17 hours
    • Infants (4-12 months): 12-16 hours (including naps)
    • Toddlers (1-2 years): 11-14 hours
    • Preschoolers (3-5 years): 10-13 hours
    • School-age children (6-12 years): 9-12 hours
    • Teenagers (13-18 years): 8-10 hours
    • Adults (18-64 years): 7-9 hours
    • Older adults (65+ years): 7-8 hours

    • Insomnia: Difficulty falling or staying asleep, often linked to stress, anxiety, or poor sleep habits.
    • Obstructive Sleep Apnoea (OSA): A condition where breathing stops and starts during sleep due to airway blockage, leading to snoring and poor sleep quality.
    • Restless Legs Syndrome (RLS): An uncontrollable urge to move the legs, often causing discomfort and disrupting sleep.
    • Narcolepsy: A rare neurological disorder that causes excessive daytime sleepiness and sudden sleep attacks.
    • Circadian rhythm disorders: Issues like shift work sleep disorder or delayed sleep phase syndrome, where the body’s internal clock is misaligned with normal sleep times.
    • Parasomnias: Unusual behaviours during sleep, such as sleepwalking, night terrors, or talking in sleep.
