Leviticus 23:40 And ye shall take you on the first day the boughs of goodly trees, branches of palm trees, and the boughs of thick trees, and willows of the brook; and ye shall rejoice before the Lord your God seven days. 42 Ye shall dwell in booths seven days; all that are Israelites born shall dwell in booths.
[Counsels On Diet And Foods pp 104] The influence of pure, fresh air is to cause the blood to circulate healthfully through the system. It refreshes the body, and tends to render it strong and healthy, while at the same time its influence is decidedly felt upon the mind, imparting a degree of composure and serenity. It excites the appetite, and renders the digestion of food more perfect, and induces sound and sweet sleep.
The lungs should be allowed the greatest freedom possible. Their capacity is developed by free action; it diminishes if they are cramped and compressed. Hence the ill effects of the practice so common, especially in sedentary pursuits, of stooping at one's work. In this position it is impossible to breathe deeply. Superficial breathing soon becomes a habit, and the lungs lose their power to expand. A similar effect is produced by tight lacing.
Thus an insufficient supply of oxygen is received. The blood moves sluggishly. The waste, poisonous matter, which should be thrown off in the exhalations from the lungs, is retained, and the blood becomes impure. Not only the lungs, but the stomach, liver, and brain are affected. The skin becomes sallow, digestion is retarded; the heart is depressed; the brain is clouded; the thoughts are confused; gloom settles upon the spirits; the whole system becomes depressed and inactive, and peculiarly susceptible to disease.
Psalms 42:5 Why art thou cast down, O my soul? and why art thou disquieted in me? hope thou in God: for I shall yet praise him for the help of his countenance.
May The Lord add His blessing to the study of His word. God bless!
