INSECTIVOROUS See also:

PLANTS . Insectivorous or, as they are sometimes more correctly termed, carnivorous plants are, like the parasites, the climbers, or the succulents, a physiological assemblage belonging to a number of distinct natural orders. They agree in the extraordinary See also:habit of adding to the supplies of nitrogenous material afforded them in See also:common with other I carried out is no doubt the vaso-motor See also:system, which controls the contraction and dilation of the See also:blood-vessels. In See also:sleep the vessels in the See also:brain automatically See also:contract, but when the brain is working actively a plentiful See also:supply of blood is required, and the vessels are dilated. If the activity is carried to See also:great excess the vessels become engorged, the mechanism does not See also:act and sleep is banished. In See also:insomnia this See also:condition has become fixed. When a breakdown has happened or is pending the only treatment is See also:complete See also:rest, combined, if possible, with See also:change of See also:air and See also:scene; but if the See also:mischief has gone far it will take very See also:long to repair, and may never be repaired at all. In no See also:matter of See also:health is the importance of " taking it See also:early " more pronounced. Delay is the worst See also:economy. A few days' See also:holiday at the commencement of trouble may See also:save months or years of enforced idleness. See also:Sea-air sometimes acts like a See also:charm. But if it is impossible to give up See also:work and leave worry behind, even for a See also:short See also:time, sleep should be carefully wooed by every possible means.

In the first See also:

place, plenty of time should be devoted to it, and no See also:chance should be missed. That is to say, the See also:night should not be curtailed at either end, and if sleepiness approaches in the daytime, as it often does, it should be encouraged. It is better to See also:lie still at night and try to sleep than to give way to restlessness, and a few minutes snatched in the daytime, when somnolence offers the opportunity, has a restorative effect out of all proportion to the time occupied. Then all accidental causes of disturbance should be avoided. See also:Lights and sounds should be excluded, comfort studied and digestion attended to. Fresh air is a great help. As much time should be spent out of doors as possible, and exercise, even to the point of fatigue, may be found helpful. But this requires watching: in some cases bodily exhaustion aggravates the malady. A little See also:food (e.g. a See also:glass of hot See also:milk) immediately before going to See also:bed is useful in inducing sleep, and persons who are See also:apt to See also:wake in the night and lie awake for See also:hours may obtain See also:relief by the same means. Hypnotic drugs, which have greatly multiplied of See also:late years, should only be taken under medical See also:advice. The real end to aim at is the restoration of the natural See also:function, and the substitution of artificial sleep, which differs in See also:character and effect; tends rather to prevent than to promote that end. It is often possible to induce sleep by rhythmic breathing.
