reaktywacj

Reaktywacja is a Polish term meaning the process of restoring activity to something that has become inactive or dormant. The word is formed from re- (again) and aktywować (to activate), and its English equivalent is reactivation. It is used across diverse fields to denote revival or renewed functioning after a period of inactivity.

In biology and medicine, reactivation can refer to the reappearance of a latent pathogen after a period of dormancy, or the revival of cellular or tissue activity following a pause due to illness or treatment. Triggers for reactivation may include changes in the immune system, stress, or injury.

In chemistry and materials science, reactivation describes restoring the activity of a catalyst or material that has become deactivated. This often involves regeneration or cleaning processes that remove fouling, restore active sites, or reprocess the material for repeated use.

In technology and computing, reactivation refers to making a suspended or deactivated account, license, or device active again. This can follow subscription renewal, password recovery, or a system reset, and is typically supported by policy or software mechanisms to re-establish access.

In economics and industry, reactivation denotes the revival of economic activity, markets, or infrastructure after a downturn or stagnation. It can involve policy measures, investment, or project resumption aimed at restoring growth and employment.
