Ventilation:
Open the windows or set heating and air conditioning
units to bring in fresh air. Air out your house every day. Keep proper
ventilation in mind wherever you are. Avoid car exhaust, tobacco smoke,
and stuffy ill-ventilated rooms.
Deep Breathing:
Take several deep breaths to clear the mind
and increase the energy level.
1. Find the freshest air available. Go
outdoors if possible.
2. Stand erect.
3. Draw as much air into your lungs as they will hold. Imagine it going
right down into your belly. Feel your stomach expand.
4. Hold your breath for a few seconds.
5. Empty your lungs as completely as possible; use your stomach muscles
to gently push out the last bit of air.
6. Repeat the process five or six times.
7. Take a fresh air break several times daily.
Most
people use less than half of their lung capacity. They are not getting
all the potential benefits from the
air they breathe. Consciously use your stomach muscles to fill and empty
your lungs several times a day, and deep breathing will soon become a
habit.
Exercise:
A good workout forces you to breathe deeply and speeds up the circulation
of oxygen-rich blood throughout the body; this saturates each cell
with oxygen.
Whenever possible, exercise outside in the morning when the air is cleanest.
Posture:
The way we stand and sit affects the amount of air the lungs can hold.
When we sit up straight and "walk tall", we allow them to enlarge and
work at full capacity. When we habitually stoop or slouch it is impossible
to breathe deeply. Superficial breathing soon becomes a habit and the
lungs lose their power to expand and receive a sufficient supply of
oxygen.
Clothing:
What we wear affects the amount of oxygen available for our use. Loose
comfortable clothing allows the lungs freedom to inflate; tight, constrictive
clothing around the abdomen tends to restrict breathing. 
Plants:
From the rainforest, to the city park, to the home, plants serve the very
important function of recycling the atmosphere. They absorb carbon
dioxide from the air and produce oxygen for us to breathe. Some provide
the added advantage of removing toxic pollutant from the air.
A Rural Environment:
Fresh air has a different chemical makeup from the indoor air most of us
breathe; it is ionized or electrically charge, which is the primary
reason for its multitude of health advantages. This air is produced
in natural settings, around trees and moving water, in sunlight, and
after thunderstorms.
Fresh country air soothes the nerves, stimulates the appetite, and induces sound refreshing sleep.
If you are fighting sickness, fresh air, in combination with the other principles of health, is a powerful remedy.
