You check the time, turn over in bed, try to fall back asleep... and the more you try, the less you succeed. Sleep disorders often reflect an imbalance between the daily rhythm, the state of the nervous system, and evening habits. Seeking a remedy for insomnia then involves less forcing sleep than recreating conditions favorable to rest. Let's explore these natural solutions that promote more stable and restorative sleep.
Common causes of insomnia
An active mind at bedtime
When you lie down, your body slows down but your mind can remain active. Rumination or anticipation of the next day: this cognitive activity maintains a state of wakefulness incompatible with falling asleep.
Research shows that this mental activation at bedtime is directly linked to sleep disorders. A study published in the journal Sleep Medicine It is observed that the higher the cognitive activity in the evening, the longer the time to fall asleep and the shorter the sleep.
What stands in the way here is less a lack of fatigue than a difficulty in leaving the state of vigilance. Sleep cannot fully settle as long as this mental activity remains present. In this context, a remedy for insomnia mainly involves promoting a gradual calming of the mind, rather than trying to fall asleep at all costs.
A nervous system on alert
Even in the absence of intrusive thoughts, the body can remain tense. Breathing is more shallow, heart rate slightly elevated, and muscles struggle to fully relax. Fatigue is present, but the body does not yet seem ready to find sleep.
This functioning corresponds to persistent activation of the sympathetic nervous system (the one that prepares for action) while falling asleep requires, on the contrary, a shift to the parasympathetic system, associated with rest.
Research in sleep medicine describes this state as hyperarousal, where the body remains activated on both nervous and physiological levels, even at bedtime. This prolonged activation is considered a central mechanism of insomnia. Specifically, the body fails to transition into relaxation. As long as this shift does not occur, falling asleep can remain difficult, and sleep may be lighter or fragmented.

A desynchronized sleep rhythm
Sleep does not depend solely on fatigue: it follows an internal rhythm, called the circadian rhythm, which organizes phases of wakefulness and rest over 24 hours.
This rhythm relies on very concrete cues: exposure to natural light, wake-up and bedtime schedules, and daily habits. When these become irregular (late bedtime, screens in the evening, lack of light in the morning), the body receives conflicting signals. Falling asleep can then be delayed, take longer, and sleep cycles can fragment.
The chronobiology research show that light plays a central role in this regulation by directly influencing the secretion of melatonin, the hormone involved in falling asleep and synchronizing sleep.
Natural remedies for insomnia
Relying on plants to promote falling asleep
Some plants are traditionally used as remedies for insomnia, especially when falling asleep is slowed by nervous tension or persistent mental activity.
The passionflower and valerian are among the most studied in this context by promoting faster sleep onset and improved sleep quality. Their action is part of a broader regulation of alertness, supporting the transition to rest.
Lemon balm is also used, but with a slightly different role. It mainly acts on calming and reducing nervousness, which can indirectly facilitate falling asleep when it is disturbed by stress.
Taken at the end of the day, alone or in combination, these plants help guide the body toward a state more favorable to sleep, without trying to induce sleep artificially.
Supporting deeper and more restorative sleep
Beyond falling asleep, sleep quality depends on the stability of cycles throughout the night. When the body remains sensitive to micro-awakenings or stress variations, sleep can become lighter, with frequent awakenings and a feeling of incomplete recovery in the morning.
In these situations, the challenge is to promote a sufficiently stable state of relaxation to allow the body to remain asleep. Certain factors can contribute to this, notably an adequate intake of magnesium, which is involved in regulating the nervous system and the stress response.

Reduce the impact of stress on falling asleep
Stress does not always manifest obviously, but it often leaves a trace at the end of the day: diffuse tension, difficulty relaxing, persistent feeling of alertness. You may feel tired while having trouble finding a calm enough state to fall asleep.
When looking for a remedy for insomnia, it is more relevant to act upstream by gradually reducing this level of activation. Adaptogenic plants, such as ashwagandha, are recognized for supporting this regulation. They contribute to better resistance to stress and a more stable return to calm. Over time, this soothing can result in smoother falling asleep and less fragmented sleep, especially when difficulties are related to nervous overload.

Techniques to manage insomnia at bedtime
Establish an evening routine
An evening routine is not just about relaxing before sleep. It mainly serves to send repeated signals to the body indicating that the day is ending. Without these cues, the transition to sleep can remain unclear, especially after a stimulating day.
Start by structuring the 30 to 60 minutes before bedtime with simple and consistent actions:
● Gradually dim the light;
● Avoid screens;
● Slow down the pace of activities;
● Rely on the meditation techniques to soothe the mind;
● Incorporate gentle practices like yin yoga that promote a gradual relaxation of the body and a decrease in the level of tension accumulated during the day.
What matters above all is regularity. By repeating the same sequences every evening, the body eventually recognizes this moment as a transition to rest, which facilitates falling asleep without having to force it.
Apply the 20-minute rule in case of awakening
Staying in bed waiting for sleep to return can maintain insomnia. When falling asleep does not happen, or in case of prolonged nighttime awakening, the brain can gradually associate the bed with a state of wakefulness rather than rest.
We then recommend getting up if sleep does not return after 15 to 20 minutes. Settle in a quiet environment with soft lighting, and engage in a low-stimulation activity (light reading, breathing, quiet time) before going back to bed when the feeling of sleepiness returns. This approach will help re-associate the bed with sleep.
Practice breathing or body scan
When the body remains tense, lying down is not always enough to trigger sleep. Some simple techniques can help you initiate this relaxation by acting directly on the breathing rhythm and physical sensations.
● Slow and regular breathing, for example with a rhythm of 4 seconds inhaling and 6 seconds exhaling, gradually slows physiological activity. You can practice it for a few minutes, lying down, simply focusing your attention on the breath.
● The body scan works on a different principle: it involves focusing attention on different areas of the body, voluntarily releasing tension, from the feet up to the head. This progression helps to leave the state of alertness and enter deep relaxation.
Habits that sustainably improve sleep quality
Stabilize your bedtime and wake-up times
Sleep follows an internal rhythm that needs regular markers to remain stable. Going to bed and waking up at very variable times from one day to the next can disrupt internal signals and make falling asleep more uncertain, even when tired.
The goal is then not just to go to bed earlier, but rather to give the body reliable anchor points. A stable wake-up time often serves as the most effective marker, as it sets the entire sleep-wake cycle. Start by fixing it, then let the bedtime gradually adjust according to your level of sleepiness.
With a few days of consistency, the time of falling asleep generally becomes more natural, without needing to force it.
Expose yourself to light at the right time of day
Light is one of the main markers of the sleep-wake rhythm. However, its effect depends on the time you are exposed to it: sufficient light early in the day helps anchor this rhythm, while late exposure is more likely to shift it.
Practically, going out into natural light within an hour after waking, even briefly, sends a clear signal to the body. Conversely, in the evening, gradually reducing light intensity, especially from screens, helps avoid delaying melatonin secretion. This contrast between a bright morning and a gentler end of the day helps the body regain clearer cues and promotes more spontaneous falling asleep.
Adjusting your diet and supporting nervous system balance
Diet does not directly affect falling asleep, but it influences alertness at the end of the day. Dinner timing plays a key role here: having a meal at least 2 to 3 hours before bedtime gives the digestive system time to slow down. Conversely, a dinner that is too late or too heavy can maintain high physiological activity (digestion, body temperature), which is not compatible with falling asleep.
● Favor simple and easily digestible foods: cooked vegetables and moderate starches (brown rice, sweet potato) combined with light protein sources like eggs or fish.
● Some nutrients also help regulate the nervous system, notably magnesium (green vegetables, whole grains, seeds).
● Tryptophan, an amino acid involved in the synthesis of serotonin and then melatonin (found for example in eggs, seeds, or legumes), also contributes to improving falling asleep and sleep quality.
On the contrary, it is better to limit stimulants in the second half of the day (coffee, tea, chocolate) as well as alcohol, which can promote falling asleep but often fragments sleep during the night. Instead, choose soothing infusions like chamomile or verbena to ease the transition to rest at the end of the day.
● Sleep does not depend solely on tiredness: it relies on a balance between lifestyle rhythm, nervous system state, and daily habits.
● An active mind or a tense body can keep you awake, even when you are tired. Calming this level of activation is usually an essential step.
● Certain plants like passionflower or valerian can help with falling asleep, while others, such as lemon balm or adaptogens, mainly act on stress regulation.
● Practices like meditation, breathing exercises, body scanning, or yin yoga offer concrete support to address insomnia.
● Regularity plays a central role: stable wake-up times, morning light exposure, and an evening routine help synchronize the sleep rhythm.
● Diet indirectly influences sleep: a light dinner, eaten early enough, and limiting stimulants late in the day promote smoother falling asleep.

FAQ Remedy for insomnia
Which remedy for insomnia really works?
The most effective remedy for insomnia depends on what disrupts sleep: nervous tension, irregular rhythm, or evening habits. In most cases, combined adjustments (regular schedules, stress management, relaxation techniques) lead to lasting results. A single solution rarely suffices.
Why am I tired but unable to sleep?
This delay is often linked to a persistent state of alertness. The body is tired, but the nervous system remains active, preventing the relaxation needed to fall asleep. Stress, irregular rhythms, or late exposure to light can maintain this state.
What to do in case of prolonged nighttime awakening?
When sleep doesn’t return, staying in bed can maintain wakefulness. It’s better to get up after a while, settle in a quiet, dim environment, and then go back to bed as soon as drowsiness returns. This helps preserve the association between bed and sleep.
How to fall asleep faster at night?
Falling asleep becomes smoother when the body recognizes regular cues. Reducing light in the evening, slowing down activities, and establishing a stable routine help anticipate the time for rest. Techniques like slow breathing, meditation, or body scanning can also help lower tension levels.
Which plants can help with insomnia?
Some plants are used as remedies for insomnia, especially when difficulties are related to nervous tension. Passionflower and valerian are associated with faster sleep onset, while lemon balm mainly acts to soothe. Their effectiveness depends on the context and regularity of use.
Do screens really prevent sleep?
Yes, late exposure to screens can delay falling asleep. The light they emit disrupts the natural sleep signals. Reducing their use at least one hour before bedtime helps ease the transition to rest.
Do naps disrupt nighttime sleep?
A short nap early in the afternoon (20 to 30 minutes) is generally well tolerated. However, a late or too long nap can reduce sleep pressure and delay falling asleep at night.
