There is a type of tiredness that does not lead to sleep. You lie down, the body stops moving, but the mind keeps going — replaying the day, anticipating the next one, constructing scenarios that do not yet exist. The darkness becomes a screen onto which thoughts are projected that would not find space during the day.
This is not weakness, nor lack of willpower. It is the result of a nervous system that has not received the signal that the work is done. The boundary between active time and rest time has become porous — and the mind, accustomed to being always in motion, struggles to shift gear.
The problem with insomnia is not always sleep itself. It is often the relationship that forms with it: the waiting, the frustration, the constant monitoring of how much one is or is not sleeping. This state of prolonged vigilance is exactly the opposite of what the body needs in order to fall asleep.
What happens when you cannot sleep
Sleep is not a passive state: it is an active recovery process, during which the central nervous system consolidates memory, regulates emotions, and restores cognitive functions. When this process is interrupted — or fails to start — the consequences accumulate quickly: irritability, difficulty concentrating, increased emotional reactivity.
Chronic insomnia is associated with a higher risk of mood disorders, cognitive deficits, and, in the long term, physical conditions such as hypertension and a weakened immune system. It is not a minor disorder.
What the research says
Scientific interest in the relationship between mindfulness meditation and sleep quality has grown significantly in recent years, producing a body of evidence that, despite the necessary methodological caveats, points in consistent directions.
A meta-analysis published in the Annals of the New York Academy of Sciences (Rusch et al., 2019), which analysed 18 randomised controlled trials involving 1,654 participants, found moderate-strength evidence that mindfulness meditation significantly improved sleep quality compared to non-specific controls, both at the end of the intervention and at follow-up. The researchers observed that the benefits tended to be maintained or to increase over time, suggesting a cumulative effect of practice. (Rusch H.L. et al., Annals of the New York Academy of Sciences, 2019; 1445(1):5–16)
A further meta-analysis, published in the Journal of Psychosomatic Research (Gong et al., 2016), analysed 6 randomised trials involving 330 participants diagnosed with insomnia, finding that mindfulness meditation was associated with significant improvements in total wake time and perceived sleep quality. The researchers concluded that meditation may represent a promising option as a complementary treatment for sleep disorders. (Gong H. et al., Journal of Psychosomatic Research, 2016; 89:1–6. doi: 10.1016/j.jpsychores.2016.07.016)
A randomised clinical trial conducted by Black et al. and published in JAMA Internal Medicine (2015) compared a 6-week MBSR programme with a sleep hygiene intervention in older adults with sleep disturbances: the meditation group showed significantly greater improvements in insomnia symptoms, depression, and the daytime consequences of poor sleep quality. (Black D.S. et al., JAMA Internal Medicine, 2015; 175(4):494–501)
A methodological note
As with other areas of mindfulness research, the variability between studies in this field — in terms of populations, protocols, and measurement tools — calls for caution in interpreting results. The phrasing used on this page reflects this complexity: “is associated with”, “several studies show”, “results suggest” are not euphemisms, but the appropriate language for describing promising evidence that has not yet reached the level of causal certainty.
Meditatina is not a therapy for insomnia. It is a gesture that can help the nervous system find the direction of rest — to signal, gently, that the day is over.
