Sleep problems can have many different causes. Stress, irregular schedules, nighttime screen use, caffeine or alcohol consumption, certain medications, work shifts, or changes in our biological clock can all affect sleep.
Therefore, before looking for something to help you sleep better, it's worth asking yourself: why am I sleeping poorly?
Not all sleep problems are the same
Having trouble sleeping doesn't necessarily mean you have insomnia.
We can encounter various situations: people who take a long time to fall asleep, others who wake up several times during the night, those who wake up too early, and those who sleep enough hours but feel their rest wasn't restorative.
When these difficulties persist over time and affect daytime functioning, it's advisable to consult a healthcare professional to determine what might be happening.
Sleep is linked to numerous physiological processes, and maintaining a proper routine is a cornerstone of well-being.
Why is it sometimes so hard to fall asleep?
One of the mechanisms involved in our sleep is the circadian rhythm, a kind of internal clock that helps the body synchronize various processes with the approximately 24-hour cycle.
Light plays a particularly important role in this mechanism.
During the day, exposure to light helps keep us alert. When darkness falls, the body progressively increases the production of melatonin, a hormone primarily produced by the pineal gland that helps regulate the sleep-wake cycle.
Here lies one of the reasons why certain modern habits can hinder sleep.
Going to bed at different times each night, being exposed to bright light at night, using screens right before sleep, working shifts, or traveling across multiple time zones can disrupt the signals our body uses to know when to stay awake and when to prepare for rest.
Melatonin: the hormone linked to our biological clock
Melatonin is produced naturally in our body, and its release is closely tied to darkness.
Therefore, it shouldn't be seen simply as a substance that "induces sleep" but rather as part of the system through which our body regulates when rest should occur.
It also exists in the form of a dietary supplement.
Indeed, it has become one of the most well-known ingredients in sleep-related supplements, especially among people who occasionally have trouble falling asleep or whose sleep schedule has been disrupted.
European legislation recognizes a very specific health claim: melatonin helps reduce the time it takes to fall asleep when 1 mg is consumed close to bedtime.
However, this does not mean that melatonin is a universal solution for any sleep problem or that it should be considered a treatment for insomnia.
When might it make sense to consider a sleep supplement?
Dietary supplements should play a secondary role to sleep habits.
Maintaining relatively consistent schedules, reducing exposure to bright light before bed, limiting stimulants in the late hours of the day, and having a dark, quiet, and comfortable bedroom are simple measures that help prepare the body for rest.
When, despite taking care of these aspects, occasional difficulties in falling asleep arise, some people consider incorporating supplements into their nighttime routine.
Among the various alternatives available, melatonin is one of the most commonly used ingredients. Supplements come in different forms—tablets, capsules, drops, sprays, or gummies—and there are also formulas that combine melatonin with other ingredients.
When choosing, it's important to check the dosage per serving and the instructions for use, rather than assuming that a higher quantity necessarily leads to a better result.
Melatonin, valerian, passionflower, magnesium… are they the same?
No. Under the general term "sleep supplements," we find products with very different compositions and purposes.
Melatonin is directly related to regulating the sleep-wake cycle. Other supplements contain plants like valerian, passionflower, lemon balm, or California poppy, traditionally used in relaxation products.
There are also formulas that include minerals, amino acids, or other nutrients.
Therefore, when comparing natural sleep products, it's important to look at the complete composition, the amount of each ingredient, the format, and individual needs, rather than choosing solely based on the number of ingredients listed on the label.
And it's important to remember that "natural" doesn't automatically mean suitable for everyone.
What no supplement can replace
There's an understandable temptation when you've had several nights of poor sleep: to look for something that will quickly solve the problem.
However, a supplement cannot indefinitely compensate for habits incompatible with good rest.
Some basic measures remain fundamental:
- Maintain similar bedtimes and wake-up times.
- Avoid caffeine and other stimulants in the late hours of the day.
- Reduce exposure to screens and bright light before sleep.
- Avoid habitually using the bed for work or checking your phone.
- Keep the bedroom dark, quiet, and at a comfortable temperature.
- Engage in regular physical activity, avoiding very intense exercise just before bed.
- Try to get exposure to natural light during the early hours of the day.
- The goal is for our body to receive consistent signals about when to be active and when to prepare for rest.
When should we consult a professional?
An isolated bad night is usually not a cause for concern. However, when sleep problems recur for weeks, interfere with work or daily activities, cause excessive daytime sleepiness, or appear alongside other symptoms, seeking medical advice is advisable.
You should also consult a doctor before using certain supplements if you are taking medications, have chronic illnesses, or during pregnancy and breastfeeding.
Persistent sleep problems can have many different causes, and relying solely on supplements may delay the identification of the real issue.
Sleeping better starts long before you get into bed
The growing popularity of melatonin has brought attention to an issue that perhaps didn't receive enough focus for years: the importance of sleep for our daily lives.
Melatonin plays a significant role in our biological clock, and supplements containing it can be useful in certain situations, especially when there are occasional difficulties falling asleep.
But rest depends on much more than just one ingredient.
Regularity, light, physical activity, diet, stress, and nighttime habits are all part of the same equation. Understanding what is disrupting your sleep is almost always the first step toward improving it.
