- difficulty falling or staying asleep (insomnia)
Generalised anxiety disorder in adults - Symptoms
In particular, apocrine glands are involved in nervous sweating as they are sensitive to adrenaline. They secrete a milky fluid which can become odorous when mixed with skin living bacteria.
For most mammals, however, apocrine sweat glands secrete an oily (and eventually smelly) compound that acts as a pheromone, territorial marker, and warning signal. Being sensitive to adrenaline, apocrine sweat glands are involved in emotional sweating in humans (induced by anxiety, stress, fear, sexual stimulation, and pain).
Apocrine sweat gland
A more reliable resource says
Emotional sweating is a physical reaction to emotive
stimuli like stress, anxiety, fear and pain that
can occur over the whole body surface, but is
most evident on palms, soles and in the axillary
region
[...]
Apocrine sweat glands respond to emotional
stimuli such as anxiety, pain or sexual arousal.
Apocrine secretion takes place as apical budding off
from the luminal cells and is under adrenergic
control, via adrenaline and noradrenaline
[...]
The fluid secreted by the apocrine sweat gland
is an oily, odourless substance, containing proteins,
lipids and steroids.
[...]
Recently, it was
shown that two apocrine proteins, referred to as
apocrine secretion odour-binding proteins 1 and 2
(ASOB1 and ASOB2) function as carrier proteins
for volatile odour molecules, e.g. (E)-3-methyl-2-
hexenoic acid, which are linked as amino acid
conjugates and are subsequently released by bacterial
enzymes. ASOB2 was shown to be identical
with the lipocalin apolipoprotein D.
ASOB1 shares homology to the a-chain of apolipoprotein
J. As in other species, lipocalins serve
as carrier proteins for pheromones; an analogous
function has been suggested for ASOB1/2.
[...]
Moreover, several odoriferous sulfanylalkanols
were identified as axillary odour components, that
are presumably released from cysteine conjugates.
A respective cystathione-b-lyase has been cloned
from an axillary
