Finally, vacation time! Yet, instead of instantly feeling energized, you may find yourself drained, achy, or facing a headache. This awkward feeling that tends to surface during the weekend or at the start of time off goes by a name: leisure sickness. The phenomenon exists in scientific literature, but it remains poorly understood and does not constitute a medical diagnosis.
Illness at the start of vacation: what is leisure sickness?
Leisure sickness, sometimes called the “paradise syndrome,” describes a perplexing situation. A person feels relatively well during work periods, then develops symptoms when they stop.
Dutch psychologist Ad Vingerhoets and colleagues studied this phenomenon in the early 2000s. Their pilot study involved 1,893 Dutch adults. The most frequently reported symptoms during leisure were headaches, fatigue, muscle aches, and nausea. During vacations, some participants also reported symptoms resembling a cold or flu.
This study mainly described a subjective experience. It does not prove that stopping work directly causes a disease. Leisure sickness is not recognized as a medical condition in standard classifications.
Why does the body seem to let go as you unwind?
Several hypotheses have been proposed. The first concerns the abrupt change in pace. During a busy period, constraints, deadlines, and the focus on work can mask signs of fatigue. Once the pressure eases, these sensations become more noticeable.
Chronic stress could also play a role in how the body reacts. However, claiming that immune defenses “collapse” as soon as vacation begins would be too simplistic. The interactions between stress, sleep, the nervous system, and immunity are complex.
Finally, the act of leaving work behind can itself be tiring: last-minute preparations, overnight travel, changes in diet, jet lag, heat, or unusual alcohol use. A genuine infection can also emerge at this moment, unrelated to any relaxation.
Who is most likely to suffer during vacations?
In the initial study, those affected often described themselves as highly invested in their work. They also mentioned a heavy workload, a strong sense of responsibility, and difficulties switching from work to rest.
The phenomenon could thus affect more those who remain in a constant state of tension. This particularly concerns people who check messages late at night, postpone their breaks, or struggle to delegate.
Be careful not to turn this into a blanket rule, though. Severe fatigue at the start of vacation can simply reveal an infection, a sleep debt, or another health issue unrelated to work.
How to avoid getting sick at the start of vacation?
The goal isn’t to stay busy at all costs. It’s rather about avoiding the big swing between overloaded weeks and a sudden stop, itself preceded by a flurry of preparations.
Ease up before departure
If your schedule allows, finish priority tasks several days before you leave. Avoid clustering all urgent items into your last day. A clear handover list also helps you depart with a calmer mind.
Throughout the year, short breaks and a few days off spread out can limit fatigue buildup. These respites don’t replace real vacations, but they prevent waiting for exhaustion to force a pause.
Preserve your sleep
Staying up very late to “enjoy” the early evenings doesn’t always help the body recover. Keep relatively regular hours and give yourself calm mornings if you feel the need.
A nap can be beneficial, provided it doesn’t disrupt your nighttime sleep. A short break taken in the early afternoon usually works better than a long late nap.
Stay active, but without a military schedule
Walking, swimming, gentle cycling, or yoga can ease the transition. Choose an activity you enjoy and that matches your fitness level. Vacations aren’t the best time to start a brutally intense training program.
Moving regularly contributes to physical and mental well-being. However, you don’t need to fill every hour. Reading, gardening, playing, or doing nothing can also be part of restorative rest.
Avoid excesses in the first days
Travel, sun, cocktails, heavy meals, and short nights can form a taxing cocktail. Drink water regularly, especially in hot weather, and try to maintain a balanced diet during vacation as much as possible.
Handwashing remains useful in transit, in crowded places, and before meals. It reduces the transmission of many infections, but it does not specifically prevent leisure sickness.
The Right Move
If possible, plan for a first day without long travel, mandatory visits, or a tight schedule. Your body will have a buffer to shift rhythms.
When should you see a doctor?
It’s tempting to attribute all fatigue to stress. Yet physical symptoms can have many causes. See a doctor if fatigue persists despite rest, worsens, or returns with every vacation period.
A medical opinion is also recommended if it comes with a high fever, shortness of breath, chest pain, feeling unwell, repeated vomiting, or other worrying signs. If in doubt, don’t self-diagnose leisure sickness.
Finally, if you never manage to disconnect, if work invades your nights, or if exhaustion takes hold, talk to your doctor. These signals can reveal an excessively high stress level that merits care, even before the next vacation.
Truly restorative time off combines rest, pleasure, and a freer rhythm. It also prepares for a calmer return, far from the famous back-to-work blues.
