Melatonin's Effect: How the Sleep Hormone Influences Your Night's Rest

Restful sleep is essential for our well-being – but quite a few people struggle with falling asleep night after night or wake up repeatedly. Stress, too much screen time, an irregular daily rhythm, and many other things can throw our internal clock out of balance.

Here, cannabidiol (CBD) with its relaxing and stress-reducing properties can be a great help. Even better when combined with melatonin, the so-called "sleep hormone." But what exactly is melatonin, how does it work, and why does it work particularly well in combination with CBD for treating sleep disorders? The following article explains!

Recommendation for improving sleep quality

First the good news: Your body produces melatonin all by itself. Melatonin is actually an endogenous hormone produced in the pineal gland in the brain. Its main task is to regulate the sleep-wake rhythm. As soon as it gets dark, melatonin levels rise, and our body prepares for sleep.

Bright light – especially the blue light from screens – can, however, inhibit its release. Too much screen time is therefore considered a major cause of sleep initiation and maintenance difficulties.

The effect of melatonin on your sleep:

• It promotes the onset of drowsiness.

• It regulates the circadian rhythm (our "internal clock").

• It improves sleep quality and staying asleep.

• It helps us to cope more easily with changes in our normal day-night rhythm (e.g., due to jet lag or shift work).

Melatonin receptors are specialized proteins found in various areas of the body, particularly in the brain, that respond to the hormone melatonin.

There are mainly two types of melatonin receptors: MT1 and MT2. These receptors influence various physiological processes, such as:

• Regulation of the sleep-wake rhythm: Melatonin receptors, especially in the brain (particularly in the hypothalamus), help to control the day-night rhythm. Melatonin is increasingly released at night and signals to the body that it is time to rest.

• Influence on body temperature: Melatonin plays a role in regulating body temperature, as the sleep-wake rhythm is closely linked to body temperature.

• Modulation of hormone production: Melatonin receptors can also influence other hormones, such as the release of cortisol, a hormone associated with stress and wakefulness.

• Effect on the immune system and blood pressure: Melatonin and its receptors could also play a role in modulating immune responses and regulating blood pressure.

For various reasons, the body's own melatonin level may not be sufficient. Such a low melatonin level can have many causes. Artificial light sources, especially the blue light from smartphones, computers, and televisions, suppress melatonin production. Shift work, irregular bedtimes, and high stress levels can also contribute to your body not producing enough of this important hormone.

In addition, melatonin production decreases with age, starting around 55. Older people often have lower melatonin levels, hence the "early bird gets the worm" phenomenon that some young people make fun of – until it happens to them. People with chronic illnesses or hormonal disorders can also suffer from a deficiency.

Another important aspect is nutrition. The body needs certain nutrients such as tryptophan, magnesium, and vitamin B6 to produce melatonin. If these building blocks are missing, the body's own melatonin production can be impaired.

Even if it sounds fantastic: taking certain melatonin preparations alone is often not enough to effectively treat sleep disorders. Even with sufficient tiredness, stress and inner restlessness can prevent one from falling asleep or staying asleep as desired. The body may be tired, but the wide-awake brain still won't let one rest.

This is where CBD comes in. Cannabidiol has been shown to be particularly effective in reducing stress, anxiety, and tension (1), and many users enthusiastically report on the stress-reducing effects of CBD on the body. CBD interacts with the endocannabinoid system, which regulates many processes in the body, including stress perception, mood, and sleep quality.

The combination of CBD and melatonin thus combines two effective mechanisms. Melatonin signals the body that it's time to sleep, while CBD reduces stress, anxiety, and muscle tension to promote relaxed sleep onset and peaceful sleep throughout the night.

Furthermore, there seems to be a very special interaction between melatonin and endocannabinoids (i.e., the body's own cannabinoids), which could also contribute to better sleep.

There is evidence of interactions between the melatonin system and the endocannabinoid system (with CB1 and CB2 receptors). Some studies show that melatonin and endocannabinoids like anandamide can work together to promote sleep and regulate the circadian rhythm.

In addition to the interactions already mentioned between melatonin and cannabinoids in the sleep cycle, there is evidence of coordinated effects on the central nervous system. It appears that CB1 receptors can influence the release of melatonin, and conversely, melatonin could influence the activity of cannabinoids in the brain. There are also indications that the anti-inflammatory effects of both melatonin and CBD could work together. In certain situations, a combination of the two systems (melatonin and cannabinoids) could modulate the immune response and inflammatory processes. The extent to which this affects sleep and sleep quality still needs to be investigated.

It is likely that the two systems can interact in complex ways, particularly with regard to sleep regulation, inflammatory processes, and the central nervous system. Research into the interactions between melatonin and endocannabinoids is far from complete, and it seems that there is still much potential here.

However, studies already show that CBD can extend the duration of deep sleep phases, making you feel more rested in the morning. (2) Unlike other cannabinoids like THC, CBD has no psychoactive/intoxicating effects and generally shows very few side effects. This means it can be used without problems over a longer period to improve your sleep routine.

If you are already taking other medications (e.g., to improve your sleep or for other symptoms) or if you have psychological symptoms that affect your sleep, please consult your doctor or psychotherapist before use.

High-quality sleep oils with CBD and melatonin are therefore the ideal choice for improving your sleep. Products like our CBD Sleep Oil 25% contain both active ingredients in optimal dosage to facilitate falling asleep and improve sleep quality. Soothing chamomile also helps to calm down and sleep better and longer.

The correct dosage can vary individually. We recommend taking the sleep oil about 30 minutes before bedtime. To do this, place a few drops under your tongue, hold them there for about 60 seconds, and then swallow. Part of the active ingredient is already absorbed through the oral mucosa, allowing it to work particularly well and quickly. If taking drops is not for you, also try our CBD Sleep Spray.

In addition to taking effective supplements like CBD oil with melatonin, there's more you can do to improve your sleep. Here are the most important tips for a good night's sleep:

Our bodies love routines! Try to go to bed and wake up at the same time every day – even on weekends. This helps your body develop a stable sleep rhythm.

The blue light from smartphones, tablets, and computers inhibits melatonin production. If you use your phone in bed, it can make it harder to fall asleep. Therefore, you should avoid screens for at least an hour before bedtime or activate a blue light filter.

A quiet, dark, and cool bedroom promotes better sleep.

• Temperature: Ideally 16–18°C.

• Darkness: Blackout curtains or a sleep mask help against disruptive light.

• Quiet: If necessary, use earplugs against ambient noise.

Caffeine can keep you awake for up to 6 hours after consumption – therefore, avoid coffee, black tea, or energy drinks in the afternoon. Alcohol also reduces sleep quality as it shortens deep sleep phases. So skip the "relaxing" glass of red wine in the evening!

Rituals signal to your body that it's time to wind down. Try a warm shower or bath with lavender oil, treat yourself to a good book before bed (instead of social media), or try some breathing exercises, meditation, or autogenic training before going to sleep.

Taking your sleep oil as a routine can also signal to your body that it's bedtime. Use the intake as a time for yourself, for conscious breathing and realizing that you are doing something good for yourself.

Exercise improves sleep quality – but intense training directly before bed can rev up your body too much. In the evening, slower, calmer activities, such as a relaxed yoga session, are more sensible.

Heavy, greasy food in the evening burdens the digestion. Light foods with tryptophan (e.g., bananas, nuts, or oatmeal), on the other hand, promote melatonin production.

Mind racing in bed? Write down your thoughts or keep a gratitude journal to help you let go.

Side sleeping can prevent breathing problems, while back sleeping ensures a relaxed spine. Avoid sleeping on your stomach, as this can strain your neck.

Natural light in the morning regulates melatonin production and helps you feel more awake during the day and sleepier at night. Even 10–20 minutes of daylight in the morning can help!

Many people quickly resort to prescription medications for persistent sleep disorders. Even if these can provide temporary relief, they often lead to a vicious cycle of restless sleep, daytime fatigue, and the need to take more medication.

In contrast to classic medications, which often have many side effects and a significant potential for addiction, CBD and melatonin offer a gentle alternative that is not addictive and has very few side effects. These also disappear as soon as you adjust the dose.

Sleep problems can significantly impair quality of life. While many sleeping aids come with strong side effects or a risk of dependency, the combination of CBD and melatonin is a gentle and natural alternative. 

Especially people who suffer from stress or difficulty falling asleep benefit from CBD sleep oil with melatonin – for a restful night and a relaxed start to the day. In combination with smart sleep routines, you can finally find the rest you desire.
