If on weekends, you have trouble sleeping, feel nauseous, exhausted, get cold or flu symptoms or headaches, and particularly if you get ill on vacations, you may be suffering from leisure sickness. In the late 20th century, Ad Vingerhoets and Maaike van Huijgevoort, psychologists at Tilburg University in the Netherlands, first studied the syndrome of leisure sickness. Essentially, Vingerhoets and van Huijgevoort found that many people seem to get ill on weekends and vacations, not from viral based diseases, but from the fact that they are not working.

In addition to the symptoms mentioned above, leisure sickness is associated with aches and pains and an overall feeling of fatigue. Those who suffer from the condition may also have lousy vacations, because they frequently feel ill or lack the energy to enjoy the activities they planned to do. Leisure sickness is considered psychosomatic, because most people in the midst of it are not suffering from any viral or bacterial illness.

In the early studies done by these psychologists, it appeared that certain personality types are most likely to encounter leisure sickness. People who typically are overworked, expressed a lot of stress around working, or who rarely took time off from work were often leisure sickness victims. Others who tended to be affected by leisure sickness were those for whom planning vacations was viewed as especially stressful. In contrast, those people who did not report leisure sickness were likely to exhibit healthy attitudes toward work, had a balanced work and social life, and enjoyed vacation planning, not viewing it as stressful.

For some people, the sudden transition from job orientation to leisure orientation brought on symptoms of leisure sickness. It is as though people really did not know what to do with themselves, even when they had plans, because their central focus was generally on working. This manifested in the body as symptoms of stress, which in turn manifested symptoms of illness.

When people took long vacations, many reported feeling better from leisure sickness symptoms after about a week. Still some reported always being sick on vacations, no matter the length. In the first scenario, it appears that some people are able to shift their focus into a leisure instead of working mode and recover from leisure sickness after being off the job for a while.

It does appear that addressing attitudes toward work can help leisure sickness. Many who reported leisure sickness also reported thinking about work much of the time when they were not working. Some people also noted that they felt guilty for not working in their off time. It’s fairly easy to draw lines between preoccupation with work, stress, and illness.

The suggestion, however, is that curing leisure sickness means changing attitudes about work. This might mean allowing yourself to feel entitled to vacations, and during your workweek, still participating in social activities so that there is a better balance between work and relaxation. From a stress standpoint, many people are able to feel less stress when they deliberately focus on the present, not allowing their jobs to “come home with them.” This can’t always be mastered, but if every vacation represents another bout of leisure sickness, it might well be worth investigating how to change your attitude toward work.
