Mental Health

International travel is stressful. Stressors vary to some extent with the type of travel: short-term tourist travel likely creates the least stress, whereas frequent travel, humanitarian and disaster work, and expatriation cause the most. Given the stressors of travel, preexisting psychiatric disorders can recur, latent or undiagnosed problems can become apparent, and new problems can arise. In addition, jet lag, fatigue, and work or family pressures can trigger anxiety and aggravate depressive symptoms in short-term travelers.
