Many wonder so what serves to sleep and how many hours of dream are advisable. Investigations carried out in the last years confirm that at least for certain people (the subjected to high levels of daily strés), being awake is equal to be sick and sleeping to recover the health. It is that for many to sleep little or to get up early, it is equal to suffer of bad mood, headaches, to segregate high levels of hormone of the strés (cortisol, corticosterone) that affects to the heart, the levels of glucose, etc making but prone to these people to acquire diabetes, hypertension, depression, heart diseases, etc. To sleep little (at least in rats), promotes the scarce formation of cerebral new cells especially in the hippocampus with what certain brain cognitive functions deteriorate, according to a work led by Elizabeth Gould and collaborators (PNAS). Also it is known that the deprivation of the dream bears to an acceleration of the ageing and to acquire similar cognitive defects to that exhibited for chronic trinkers.

Sueño=salud. Vigilia=enfermedad, para ciertas personas.

Muchos se preguntan para que sirve dormir y cuantas horas de sueño son recomendables. Investigaciones realizadas en los ultimos años confirman que al menos para ciertas personas (las sometidas a altos niveles de estrés cotidiano), el estar despiertos equivale a estar enfermo y dormir a recuperar la salud. Es que para muchos dormir poco o levantarse temprano, equivale a padecer de mal humor, cefaleas, segregar altos niveles de hormona del estrés (cortisol, corticosterona), que afecta al corazón, los niveles de glucosa, etc haciendo mas propensas a estas personas a adquirir diabetes, hipertensión, depresión, males cardiacos,etc. Dormir poco (al menos en ratas), promueve la escasa formación de nuevas celulas cerebrales especialmente en el hipocampo con lo que ciertas funciones cognitivas se deterioran, según un trabajo realizado por Elizabeth Gould y colaboradores (PNAS). Asimismo se sabe que la deprivacion del sueño conlleva a una aceleración del enevejecimiento y a adquirir defectos cognitivos similares a los exhubidos por bebedores crónicos.

The pregnancy stress affects the future child.

The doctor Vivette Glover of the Imperial College of London is accumulating evidences of something that our mothers have come telling to sotto voce, during decades: that mistreated mothers by cruel or violent husbands, during their pregnacies gestate children affected emotionally. The Dra Vvette has demonstrated that there is a strong correlation between maternal and fetal cortisol (elevated), levels (Gitau et al 1998, 2001), and that if the mother is anxious there is less blood flow to the baby (Teixeira et al 1999). High levels of in utero testosterone may also affect the neurodevelopment of the child (Gitau et al 2005). Also it has been shown low levels of IQ (at 18 months), in children of mothers submitted to violent stresses during their pregnancies. The children born of this luck are anxious, fearful, unstable and many suffer of attention deficit hyperactivity disorder (ADHD).

El estrés gestacional afecta al futuro niño.

La doctora Vivette Glover, del Imperial College de Londres está acumulando evidencias de algo que nuestras madres han venido diciendo a sotto voce, durante décadas : que las madres maltratadas por maridos crueles o violentos, durante susembarazos, gestan niños afectados emocionalmente. La Dra Vvette, ha demostrado niveles incrementados de cortisol (la hormona del stress), bañando el liquido amniótico antenatal y bajos niveles de IQ (a los 18 meses), en hijos de madres sometidas a estreses violentos durante el embarazo. Los niños nacidos de esta suerte son ansiosos, temerosos, inestables y muchos padecen de déficits de atención asociados a desórdenes de hiperactividad (ADHD).
