self-poisoning is by maintaining an erect posture
One of the simplest and most effective methods of avoiding
self-poisoning is by maintaining an erect posture. In an erect posture
the abdominal muscles tend to remain taut and to afford proper support
or pressure to the abdomen, including the great splanchnic circulation
of large blood-vessels. In an habitual slouching posture, the blood of
the abdomen tends to stagnate in the liver and the splanchnic
circulation, causing a feeling of despondency and mental confusion,
headache, coldness of the hands and feet, and chronic fatigue or
neurasthenia, and often constipation.
