Expert Warns: Vacations Are the Perfect Time to Fix Sleep Habits

As many people prepare for their summer vacations, a timely reminder comes from sleep expert Isabelle Poirot: this period is an ideal opportunity to address poor sleep habits that have accumulated over time. With the stresses of daily life often leading to sleep deprivation, it’s crucial to understand how to make the most of this time off.

According to data from the French Ministry of Health, one in five French people sleeps less than six hours a night during the workweek, with over 30% of children and up to 70% of teenagers also suffering from insufficient sleep. This lack of rest can lead to a range of issues such as distracted attention, poor memory, irritability, and compromised decision-making. Fortunately, the summer months offer a chance to reverse this trend, provided one approaches it correctly.

Strategies for Improving Sleep During Vacation

Upon the onset of vacation, many individuals may feel tempted to sleep in until noon. However, Isabelle Poirot, a psychiatrist specializing in sleep disorders, warns against this approach. In an interview with Cerveau & Psycho, she highlights that making drastic changes to sleep patterns can lead to a state known as “mental fog,” which is not restorative. A Canadian study involving over 10,000 participants, published in the journal Sleep, confirms that oversleeping can be just as detrimental as not getting enough rest, particularly affecting high-level cognitive functions like decision-making. The goal should be to achieve between seven and eight hours of sleep per night, which is roughly an hour more than what most working adults manage during the week. Just a few nights of adequate sleep can significantly enhance reasoning abilities and complex cognitive processes.

However, duration alone is not sufficient. Poirot emphasizes the importance of maintaining a consistent sleep schedule. Deviating more than an hour from one’s usual wake-up time can disrupt the body’s internal clock, leading to what is termed “social jet lag.” This condition mimics the disorientation felt after a long flight but is triggered by simple lifestyle changes. Her advice is somewhat counterintuitive: even after a late night, it’s better to rise at a reasonably fixed time and compensate with a short nap. This nap should be brief—around 15 to 20 minutes in the early afternoon—to avoid slipping into deep sleep, which can lead to waking up feeling groggy.

Maintaining Healthy Sleep Habits Post-Vacation

The transition back to routine is often where progress can falter. A Dutch study involving 54 employees on vacation revealed that the benefits gained during time off dissipated within the first week of returning to work. The return of responsibilities, stress, and abrupt wake-up calls can quickly erase the improvements made during vacation. To prevent this regression, it’s essential to plan ahead: in the week leading up to the return to work, gradually shift bedtime and wake-up time forward by 15 to 30 minutes each day. This gentle adjustment allows the internal clock to recalibrate without shock.

In the long run, the objective is to convert these positive vacation habits into lasting routines. Consistently waking up at the same time during the week, allowing for short naps when fatigue sets in, and avoiding screens, stress, or irregular hours that chip away at nighttime sleep are all vital. The brain does not differentiate between August and October—it requires the same conditions to function optimally. Are you ready to pack these keys to sustainable sleep hygiene in your suitcase?
