"Arndt's law ,  Arndt-Schulz l.  weak stimuli increase physiologic
activity, moderate stimuli inhibit activity, and very strong stimuli
abolish activity. See also hormesis.

hormesis (hor·me·sis) (hor-me´sis) [Gr. hormesis rapid motion]  the
stimulating or beneficial effect of small doses of a toxic substance
that at higher doses has an inhibitory or adverse effect. "

Hello,

The above two laws tells about effects by weak and strong stimuli. I
have few questions:-

1. What can be the weak and strong stimuli to body which can cause
physiologic activities?

2. Can stimuli be the application of any sensation to five basic
senses+ thinking including cephalic/phase effects?

3. Can weak stimuli be the stimulating the whole body or just a part of
body?

4. Whether application of stimuli to one part of body will increase
more physiologic activity or application to whole body?

Pls understand it eg;  wearing woolen cloths just on upper body--may
cause feeling more cold. Others thought can be
accupunture/accupressure, reiki, scratching/itching etc...which apply
stimuli just on one site.

5. How these laws can be applicable to immune responses?

Best wishes.
