Melatonin: a complete guide to understanding how it works

If you have trouble falling asleep, wake up during the night, or simply do not rest as you should, your body may not be producing enough melatonin.

In this article, you will discover what melatonin is, how melatonin works in your body, and what you can do to stimulate its production naturally and without side effects.

In addition, we explain how Baia Food's Probiotic Creamer™ can help you create the perfect environment to rest better every night.

What is melatonin and what is it for?

Melatonin is a natural hormone produced by your brain, specifically in the pineal gland, and acts as a biological signal to indicate that it is time to sleep. Its main function is to regulate the sleep-wake cycle, known as the circadian rhythm.

As night falls, melatonin levels gradually increase, reach their peak in the early hours of the morning, and decrease at dawn, allowing you to wake up. During the day, exposure to light —especially natural light— suppresses its production.

How does melatonin work?

Understanding how melatonin works is key to improving sleep quality. This hormone is released in response to darkness and acts on the central nervous system, helping to:

Reduce body temperature.
Relax the nervous system.
Decrease brain activity.
Prepare the body for deep rest.

In short, melatonin relaxes the nervous system and prepares the body to enter a state of rest and recovery.

Factors that affect melatonin production

Modern life can interfere with the natural production of this hormone. Some factors that reduce melatonin in your body are:

Exposure to screens and blue light at night. Irregular sleep schedules.
Prolonged stress and anxiety.
Heavy dinners just before going to sleep.
Environments with excessive light at night.

Melatonin, anxiety and stress: an inverse relationship

Melatonin and cortisol —the stress hormone— have an inverse relationship. When cortisol is high (for example, due to chronic stress or constant worry), melatonin decreases, and therefore sleep is affected.

That is why many people with insomnia also experience anxiety, and vice versa. Producing an adequate amount of melatonin not only helps you sleep better, but also reduces stress and promotes a more balanced mental state.

Natural melatonin or sleep supplements?

While synthetic melatonin supplements are available on the market, prolonged use may reduce the body's ability to produce it on its own.

That is why, at Baía Food, we developed Probiotic Creamer™. A drink with a delicious chocolate flavor, formulated with natural ingredients that support relaxation, rest, and gut health. Its combination of cocoa, magnesium, plant extracts such as ashwagandha, probiotics, and pistachio phyto-melatonin helps prepare body and mind for restorative sleep. It does not contain artificial melatonin, but rather functional ingredients that activate the body's natural mechanisms to relax and prepare for sleep.

How to stimulate the natural production of melatonin

In addition to taking Probiotic Creamer™, you can implement these practices:

Avoid screens two hours before bed.
Have a light dinner at least 2–3 hours before going to bed.
Get some sun in the morning or spend time outdoors.
Take a shower 2–3 hours before sleeping, not right before.
Create a relaxing nighttime ritual: meditate, read, or breathe deeply.
Review your emotional environment: toxic relationships also affect your rest.
