6.2.14.  VIVACITY and DROWSINESS
и     The duration/parity of sleep and wakefulness periods is determined by a lot of factors, from which it is necessary to note
• physiological - primary deviations of S_A from the norm, malady; that can result both in heightened drowsiness, and in sleeplessness;
" physical - household, among them - stimuli of all five modalities from tactile and up to olfactory;
" psychological - from moral comfort and rest and up to excitation, irritation, fear, etc.;
" social - connected, in particular, with person's S labour cycle;
" mixed - such as a daily rhythm of the Earth; such as presence (or absence) of dangers, etc.
    At objective (according to external circumstances) necessity of wakefulness one should think of artificial increase of LN (Limit level of Novelty), of person's reserves mobilization. Sources for this purpose, not excluding each other, can be found on all three levels of HHYPERPHYSICUM.
"In the mentalum stratum as a classical example can serve mother's semiwakefulness at a bed of her sick child: here a source of the sentry point forming is the aggravated reaction to the state of her child, is a moral-emotional stimulus.
"In the astralum stratum - to make the energetic metabolism, astralum circulation, in particular - in acupuncture channels, more active, can be useful for example massage of an auricle - whole/entirely or separate points on it, for example, шэнь-шан-сянь (A 13), шэнь-мэнь (A 55) (by P. Nogier - see, for example, [ 119 ]), - and корпоральных points жэнь-чжун, хэ-гу (GI 4), цзу-сань-ли (Е 36), etc.
" In the physical stratum - exercises, loadings make astralum more active, speed up the blood even if the exhaustion is caused by physical overloads; but in this case, certainly, one should exercise not overloaded, but other groups of muscles. Feed problems ought to be considered also here: over-eating can lull, under-eating can increase fatiguability.
    A change of an occupation is (as it is known) the rest just because at individual's inactivity an object, which caused exhaustion, continues to remain in sphere of his psyche activity; while at transition to a new/another activity it is ousted from psyche (into UDI), like as at sleep, and with the same (qualitatively) effect.
