In this article, we will explore the fascinating role of melatonin in the body and its impact on aging, circadian rhythm, and overall health. As a sleep enthusiast, I believe it is crucial to understand the risks associated with depleted and improper melatonin production. By providing helpful suggestions and reasons for these suggestions, we can take proactive steps to optimize our melatonin levels and promote better well-being.

What is Melatonin?

Melatonin is a hormone naturally produced by the pineal gland, a tiny pea-sized gland located in the brain. Often referred to as the “sleep hormone,” melatonin plays a vital role in regulating the sleep-wake cycle, also known as the circadian rhythm. It helps to synchronize our body’s internal clock with the natural day-night cycles. A fantastic book that will teach you everything you want to know about this amazing “sleep hormone” is Melatonin Miracle: Nature’s Age Reversing, Disease Fighting, Sex Enhancing Hormone by Walter Pierpaoli M.D. PhD., William Regelson M.D. and Carol Colman. The science and research they present in this book is inspiring. Pick up a copy and prepare to be amazed at what your tiny pineal gland is capable of.

The Role of Melatonin in the Body

Melatonin’s role extends beyond sleep regulation. It acts as a powerful antioxidant, protecting our cells from oxidative stress and damage caused by free radicals. Additionally, melatonin influences various physiological processes, including immune function, blood pressure regulation, and reproductive function.

Melatonin and Aging

As we age, the production of melatonin naturally declines. This decline in melatonin levels may contribute to difficulties in falling asleep, maintaining sleep, and experiencing restorative sleep. Furthermore, decreased melatonin levels may affect the body’s ability to repair and rejuvenate itself, leading to accelerated aging and increased vulnerability to age-related diseases.

Melatonin and Circadian Rhythm

The circadian rhythm is our body’s internal clock that governs various biological functions, including sleep, hormone secretion, and metabolism. Melatonin plays a crucial role in regulating this rhythm, promoting the onset of sleep in the evening and maintaining wakefulness during the day. Disruptions in the circadian rhythm can result in sleep disorders, mood disturbances, and overall imbalance in our physiological processes.

We recently purchased a Hatch Alarm Clock and now wonder how we made it all these years without one. These are some of the benefits:

  • Sleep better: Personalize a sleep-wake routine to help you fall asleep, stay asleep & wake up refreshed.
  • Wake up naturally: Gently wake to a custom Sunrise Alarm Clock that supports healthy cortisol levels.
  • Sounds + lights + more: Create a mood any time with a library of soothing sounds, white noise & lights at your fingertips. Relax with a soft-glow reading light without the eye-straining blue hues.
  • Control via app or touch: Control with soft-touch buttons on the device, or use the free companion app for iOS or Android. Device requires Wi-Fi and Bluetooth.

When you are getting ready for bed at night this alarm clock has a yellow glow that slowly fades to a deep rose colour that mimics the setting sun. You can play white noise all night, we love the rain sounds, and in the morning 30 minutes before you wake, the colour starts as a deep rose colour brightening slowly until your alarm sounds. This is all to reset your circadian rhythm to sleep and rise with the sun. I love it so much I bring it with me when I travel.


The Effects of Depleted Melatonin

When melatonin levels are depleted, several adverse effects can occur. These include difficulties falling asleep, disrupted sleep patterns, daytime fatigue, reduced immune function, impaired cognitive performance, and increased susceptibility to stress and anxiety. Proper melatonin production is vital for maintaining optimal health and well-being.

Factors Affecting Melatonin Production

Several factors can affect melatonin production in the body. Exposure to bright light in the evening, such as from electronic devices, can suppress melatonin production and disrupt the natural sleep-wake cycle. Shift work, jet lag, and irregular sleep schedules can also interfere with melatonin production. Additionally, age-related changes and certain medical conditions may impact melatonin synthesis.

I have always been an avid reader and love to read before I fall asleep. Melatonin starts to flow three hours before midnight and any light that you are exposed prior to 9 pm stunts melatonin production. After learning this, I was upset because I really love to read and having my bright light after 9 pm was interfering with my sleep. I was thrilled when I learned about Kobo, the e-reader, because it has blue light reduction and glare free screens. Now, I can read my beloved books and avoid blue light prior to sleep.

How to Boost Melatonin Production

Fortunately, there are ways to naturally boost melatonin production and optimize its effects on the body. One crucial step is to establish a consistent sleep routine, ensuring a regular sleep schedule and creating a sleep-friendly environment. Avoiding bright lights, especially before bedtime, and incorporating relaxation techniques such as meditation or deep breathing can enhance melatonin production.

Foods to Boost Melatonin

Over the past few decades, researchers have identified melatonin in a wide variety of foods, ranging from fungi to animals and plants. Among animal foods, eggs and fish are known to contain higher levels of melatonin. On the other hand, among plant foods, nuts stand out as the richest source of melatonin. Additionally, some types of mushrooms, cereals, and germinated legumes or seeds also contribute to our melatonin intake.

Studies have demonstrated that consuming melatonin-rich foods leads to a significant increase in the melatonin concentration in the human serum. Beyond its sleep-inducing properties, melatonin has been found to exhibit a range of beneficial bio-activities. These include antioxidant properties, anti-inflammatory characteristics, immunity boosting effects, anticancer activity, cardiovascular protection, anti-diabetic, anti-obesity, neuro-protective, and even anti-aging effects.

Lifestyle Changes for Better Sleep

In addition to promoting melatonin production, adopting healthy lifestyle habits can significantly improve sleep quality and overall well-being. Regular exercise, a balanced diet, and managing stress levels can positively influence melatonin production. Creating a relaxing bedtime routine, reducing caffeine intake, and avoiding stimulating activities before bed can further support optimal sleep and melatonin synthesis.

Melatonin Supplements

For individuals experiencing persistent sleep issues or depleted melatonin production, melatonin supplements can be a viable option. These supplements are available over-the-counter and can help regulate sleep-wake cycles. However, it is crucial to consult a healthcare professional before starting any supplementation regimen, as dosage and timing should be tailored to individual needs.

People use various types of supplemental melatonin to improve their sleep quality, and they have a wide range of options to choose from. These options cater to different preferences and needs, making it easy to find the right fit. You can find melatonin in the form of capsules, tablets, sublingual tablets, gummies, and even melatonin-infused beverages. With so many choices available, it’s easier than ever to find a friendly sleep aid that works for you!

I have tried many different types of melatonin over the years such as timed release, sublingual, liquid and gummies. I find a small dose, about 1 mg works best for me, and anything more tends to give me a headache. I prefer liquid under the tongue melatonin because the times release makes me feel groggy in the morning. Everyone is different and I urge you to read the book The Melatonin Miracle and find the best melatonin for you.

Risks and Side Effects of Melatonin

While melatonin is generally considered safe for short-term use, there are potential risks and side effects to be aware of. These may include daytime drowsiness, dizziness, headaches, and digestive disturbances. Additionally, melatonin supplementation may interact with certain medications, so it is essential to disclose any ongoing treatments to a healthcare provider.


In conclusion, melatonin plays a crucial role in regulating our sleep-wake cycle, supporting overall health, and combating the effects of aging. Understanding the significance of melatonin and taking proactive steps to optimize its production can lead to improved sleep, enhanced well-being, and better overall health outcomes. By adopting healthy lifestyle habits and considering melatonin supplementation under professional guidance, we can prioritize restful sleep and promote a balanced circadian rhythm.
