Overcoming the Fear of Not Sleeping: How to Rest for Real

We’re not exaggerating when we say that eight hours of uninterrupted sleep is a luxury. Judging by the statistics, in Spain people do not rest well. According to the National Health Survey, more than half of the population (57%) acknowledges that they have trouble sleeping properly on a regular basis, and approximately 4 million people have a serious or chronic sleep disorder.

For years we have been told that the key to sleeping well lies in an endless list of prohibitions: no caffeine, heavy dinners, alcohol, no screens, rooms in absolute darkness, and avoiding any stimulation before bed. These are tips not to be discarded, but they are not enough.

Proof of this is that many of its followers still count sheep night after night. The psychologist Rafael Santandreu believes that the solution does not lie in more rules, but in a radical change in mindset toward the pillow.

The Sleep Hygiene Myth

Santandreu argues in his new book Sleep When You Can’t Sleep that, although these factors influence sleep, the excessive emphasis on sleep hygiene is, in fact, a myth that can be counterproductive for the chronic insomniac. “The problem of the person who cannot sleep is not in their external habits, but in the pressure mechanisms that their own mind generates when trying to force a process that should be natural.”

“In fact, obsessing with creating perfect conditions only increases the fear that something will go wrong and, with it, the probability of staying awake,” the author and sleep specialist notes. The psychologist states that insomnia is solved, to a large extent, by relaxing in the face of the very need to sleep and accepting the possibility of wakefulness. For Santandreu, the basic premise is simple but powerful: “If one night you can’t fall asleep, nothing at all happens. By removing the pressure to meet rest, the brain stops perceiving the bed as a place of evaluation and regains its innate ability to disconnect.

Fear of Not Getting Any Sleep

The most relevant cause of chronic insomnia, according to the expert, is not everyday worries but the fear of not sleeping. While there is temporary insomnia triggered by spikes of stress, the serious problem arises when the person develops a phobia of their own night. At this point, the patient enters a spiral that Santandreu defines as “very punishing” and which can last for years.

The psychologist compares this fear to quicksand: “The more you struggle to get out and the more you strive to sleep, the more you sink into insomnia.” The constant worry about waking up exhausted the next day generates anxiety that blocks the brain’s ability to induce sleep naturally. “To break this loop, you need to stop fighting and learn to be in bed calmly, even if your eyes stay open,” he advises.

When One Fails, Three…

It sounds simple, but how does one manage to reach that so-called zen state when one is unable to close an eye? Santandreu says that the first step is to identify which type of insomnia one suffers within these three main typologies:

1. Insomnia due to fear of not sleeping. It is the most common among the chronic, where the panic of wakefulness is the driving force behind the problem.
2. Insomnia due to deprogramming of deep sleep. It often occurs after long periods of stress or after raising very young children, where the brain “learns” to maintain a light sleep and forgets how to return to depth.
3. Insomnia due to daytime problems. Those related to everyday worries that, sometimes unconsciously, prevent the relaxation needed.

The Insomnia Algorithm

For those trapped in chronic insomnia, the psychologist proposes methods based on behavioral psychology that, while challenging conventional logic, are scientifically backed and can be carried out autonomously without needing to consult any specialist.

• The exposure to not sleeping. This is a paradoxical intervention that consists of getting into bed with books or magazines with the deliberate aim of not sleeping all night. The next day, the person must strictly fulfill all their obligations: go to work, go to the gym, and continue with their usual routine. The aim is for the patient to discover, through personal experience, that it can work despite not having slept, which destroys the fear of the consequences of insomnia. Once that fear is gone, sleep returns naturally in a very short time.

• Sleep restriction therapy. Directed especially at those who suffer from deep sleep deprogramming. It involves going to bed extremely late, for example at 2 a.m. By drastically reducing the hours available in bed, sleep pressure increases, forcing the brain to recover the lost depth to optimize rest. Over the following weeks, bedtime is gradually moved earlier while maintaining the recovered quality.

What If I Don’t Sleep?

These techniques may seem contradictory, since one of the biggest concerns of the insomniac is the physical impact of a sleepless night. Santandreu’s view is reassuring: “Our body has the natural capacity to endure the occasional lack of sleep without necessarily harming health in the short term.”

To illustrate this resilience, the psychologist uses the example of cloistered nuns. These communities periodically keep vigils—entire nights devoted to prayer and meditation. At dawn, these women, aged between 18 and 88, continue with their daily tasks feeling happy and vital, demonstrating that not sleeping for one night does not necessarily translate into extreme exhaustion or illness.

Aren’t You Fatigued by the Lack of Restorative Sleep?

What really exhausts a person is not the lack of sleep itself, but the emotional tension and phobia generated by thinking, “Tomorrow I’ll be wrecked.” That anxiety is what wears the body down, not the calm wakefulness. The human brain has an astonishing capacity for recovery and, if allowed, it will automatically reclaim all the lost rest in the following nights, the psychologist explains.
