Why You Get Sick Every Time You Take a Holiday — Leisure Sickness Is Real | Bharosa

He had been planning the trip for six months. Goa with the family. Beach. Seafood. Sunsets. The day they landed, his throat was scratchy. By morning, he had a fever. By the second day, he was lying in bed in an air-conditioned hotel room watching his children play in the pool through a window. By the time he flew home, he was just well enough to walk back into the office. Within two days of being back, he felt completely fine. He told his wife he must have caught a bug at the airport. His wife, who has watched this happen every single year, looked at him for a long second and said nothing.

If this story sounds familiar, you are not unlucky. You are experiencing a documented medical phenomenon called leisure sickness — and at Bharosa Neuro Psychiatry Hospitals – Hyderabad, we see patients in our LB Nagar outpatient department every month who have lived with this pattern for years without ever knowing it had a name. The good news is that it is real, it is treatable, and once you understand what is actually happening in your body, the entire experience starts to make sense.

What Leisure Sickness Actually Is

Leisure sickness is a term first coined by Dutch psychologists Ad Vingerhoets and Maaike Van Huijgevoort in the early 2000s, describing the phenomenon in which people fall physically ill specifically during weekends, holidays, or other periods of rest. The pattern is consistent — headaches, sore throats, fevers, gastrointestinal symptoms, fatigue, muscle pain — appearing reliably the moment work pressure is lifted, and resolving when work resumes. It is not lazy. It is not imagined. It is biological, and it has a clean scientific explanation.

The American Psychological Association, the leading professional body of psychologists in the United States, has published extensively on the relationship between sustained stress, the immune system, and physical illness. The mechanism is now well understood. Chronic stress keeps cortisol elevated, which suppresses the immune system in a particular way — but the immune system stays in a state of constant alert. The moment stress is suddenly removed, cortisol drops, and the suppressed immune system rebounds with what feels like an overwhelming infection. The infection is real. The body was simply holding it at bay until you could afford to be sick.

Why High-Performers Are Especially Vulnerable

Leisure sickness is most common in people who run on adrenaline through long working weeks and only allow themselves to slow down on holidays. Doctors. Founders. Senior managers. Teachers in exam season. Parents juggling demanding jobs and small children. The body learns to function under sustained pressure by suppressing the small signals — the slight headache, the early symptoms of a cold, the muscle ache, the tiredness — that would normally make a healthier body slow down. The signals are not gone. They are queued. The holiday is when the queue empties.

Harvard Medical School, one of the world’s most respected medical institutions, has published research on the link between stress, immune dysregulation, and the timing of physical illness. The body keeps a careful score, and when the deadline finally passes, it presents the bill. The World Health Organization recognises chronic occupational stress as a global mental health and physical health concern, with measurable consequences for both psychological well-being and immune function.

How to Tell Leisure Sickness From Ordinary Illness

Look at the timing. Does it happen reliably at the start of weekends, holidays, or extended breaks? Does it resolve when you return to work? Are the symptoms vague — fatigue, headaches, sore throat, gastrointestinal upset, body aches — without a clear infectious cause? Have you ruled out specific allergies, food poisoning, or travel-related infections? Have you been working in a sustained high-stress state for months or years? If the answer to most of these is yes, you are likely looking at leisure sickness, and the underlying issue is not the holiday. It is the chronic stress that produced the body’s need to wait until the holiday to fall apart.

How Bharosa Treats the Real Cause

At Bharosa Neuro Psychiatry Hospitals Hyderabad, our consultant MD Psychiatrists and clinical psychologists assess patients with this pattern carefully. We rule out other medical causes through appropriate investigations. Where chronic occupational stress, anxiety, or burnout are identified, we treat them directly using evidence-based Cognitive Behavioural Therapy (CBT) and where appropriate, medication for the most disabling symptoms.

The goal is not just to stop ruining holidays. It is to teach the body that it can be safe outside of an office without falling apart, and to address the underlying stress patterns before they progress to full burnout, depression, or anxiety disorder. Patients consistently tell us that the first holiday after treatment feels different — quieter, lighter, and for the first time in years, actually restful.
