Has Your Tolerance Increased?
June 10, 2009
God has made us “fearfully and wonderfully” (Psalm 139: 14). One of the amazing qualities of the body is its ability to adapt. Whatever happens to the body it will always seek to return to the state of normal. Scientists and systems therapists call this homeostasis. A virus enters our body and the body works to expel it. If a person gets frightened and his heart rate increases, the body works to return it to the normal rate. What the body interprets as normal, however, can change if there is repeated challenge to the normal state of affairs. This is a powerful ability that God has created in all people, the power to adapt.
The first time an alcoholic drinks a beer, for example, he or she experiences the effects of that in the brain. Brain chemistry changes and feelings of intoxication begin. Eventually, the brain returns to normal and the person “sobers up.” If the pattern is repeated over and over again, however, the state of what normal is can change. More and more alcohol will be needed to have the same effect. This is what scientists refer to as “tolerance.”
