En lo que concierne el sentido de vida, la mayor?a de las personas se detienen a pensar y a cuestionarse: ?la vida tendr? alg?n sentido? ?Si vamos a morir, qu? sentido tiene la vida? y otros interrogantes relacionados que tendr?n respuestas de tipo religioso, moral y pol?tico, sin embargo, dichas respuestas no terminan convenciendo totalmente al ser humano, y por el contrario detona preguntas m?s profundas. Otras personas est?n centradas en conseguir el sustento necesario para vivir, pero no tienen claro para qu? viven. (Mart?nez Ortiz, Trujillo, D?az del Castillo & Jaimes Osma, 2011). Son diferentes reacciones psicol?gicas las que generan dichos cuestionamientos afectando el estado de la salud mental y emocional de aquellos que lo viven, tales como ansiedad, preocupaci?n, incertidumbre; uno de los factores m?s representativos es el estr?s, que causa un gran impacto en sus vidas. El estr?s generalmente afecta psicol?gicamente a la gran mayor?a de personas, se presentan varios tipos de eventos detonantes como las situaciones de divorcio, encarcelamiento, ex?menes acad?micos, p?rdida de los seres queridos, cuidado permanente de los familiares con discapacidad f?sica, diagn?stico de enfermedades cr?nicas, dificultades financieras y otras que t?picamente causan niveles elevados de distr?s emocional (Moscoso, 2010). Por tal motivo, es necesario resaltar que la pr?ctica de mindfulness, en la actualidad es uno de los enfoques cognitivos m?s aceptado en pa?ses europeos y en otros como Estados Unidos. Emp?ricamente la pr?ctica de mindfulness ha generado aceptaci?n en la medicina, la psicolog?a y la psiconeuroinmunolog?a en Estados Unidos, Espa?a y Chile, debido a los resultados positivos que han arrojado los diferentes estudios de esta pr?ctica en los que se han tenido en cuenta diferentes variables y distintas poblaciones.As far as the meaning of life is concerned, most people stop to think and ask themselves: will life have any meaning? If we are going to die, what meaning does life have? and other related questions that will have religious, moral and political answers, however, these answers do not end up totally convincing the human being, and on the contrary detonate deeper questions. Other people are focused on obtaining the necessary sustenance to live, but they are not clear about what they live for. (Mart?nez Ortiz, Trujillo, D?az del Castillo & Jaimes Osma, 2011). It is different psychological reactions that generate such questions affecting the state of mental and emotional health of those who live, such as anxiety, worry, uncertainty, one of the most representative factors is stress, which causes a great impact on their lives. Stress generally affects psychologically the vast majority of people, there are various types of triggering events such as divorce situations, imprisonment, academic exams, loss of loved ones, permanent care of family members with physical disabilities, diagnosis of chronic diseases, financial difficulties and others that typically cause high levels of emotional distress (Moscoso, 2010). For this reason, it is necessary to emphasize that the practice of mindfulness is currently one of the most accepted cognitive approaches in European countries and in others such as the United States. Empirically, the practice of mindfulness has generated acceptance in medicine, psychology and psychoneuroimmunology in the United States, Spain and Chile, due to the positive results of the different studies of this practice in which different variables and different populations have been taken into account.
