burnin up 4 u bebeh.


Paranoia is juz da prfect word.
y? y r u so paranoid dat im gona run away.
i wont. n u know so. 
diz is juz a part of the rough  patch dat we have 2 go through.
hold on.

speaking of burning up,
have u ever wonder y,
during fever, ur body temperature is over the roof,
but u feel so freaking cold..?
the answer may not b so simple,
but this is simplified version of th whole mechanism.

see, when ur normal, n u have no fever, 
our body temperature is 37°C(+-0.4).
n we maintain this through our hypothalamus.
there is diz thing called 'setpoint' or thermoregulatory setpoint.
this setpoint in our hypothalamus  points at 37°C.
its like the knob dat control the speed of ur fan,
or the button on the remote control of ur air conditioner.
it is the temperature dat U WANT,
the temperature that the BRAIN WANT us to be,
or the temperature SHOULD BE ACHIEVED.

lets say ur body temp reach 33°C, meaning the ACTUAL TEMPERATURE goes BELOW THE SETPOINT.
so ur brain wud tell ur body,

''hey2, ur tooo cold. better do sumthing bout it''
so u wud shiver, look 4 more heat sources, vasoconstriction n so on (boring stuff)


wut if ur body temp reach 38°C, meaning the ACTUAL TEMPERATURE goes WAY ABOVE THE SETPOINT.
so ur brain is tell ur body,

''hey2, ur too hot. better do something bout it''
so u wud move less, run away from heat, vasodilation n so on (again, boring)


dats what happen in a normal guy.
but if u got a fever, this is wut happen:

there is this thing called 
PYROGENS.
                    pyro=fire                   gen=agents
they r substances dat cause us to burn up, raise temperature,
specificly raise our setpont. but we'll get to dat later.

theres basicly endogenous pyrogen (we made it in our body) 
n exogenous pyrogen (comes from outside, wic means comes from the bacteria)

so when these substances r present in our blood, they wud travel to our 
hypothalamus.
these pyrogens INCREASE THE SETPOINT
to a higher temperature, lets say 39°C.
see, what increases here is the SETPOINT, not the body temp. (at least not yet)
so all of a sudden ur brain told ur body,

''hey2 dude, ur too clod lah. do sumthing bout it !''

but bear in mind, ur ACTUAL BODY TEMPERATURE stays the SAME. it DID NOT DECREASE.
but since ur setpoint is higher than ur actual body temp (wic is normal)
ur body think its too cold.

dats exactly wut made u feel so cold while ur body is burning up
during fever.

n since ur body think its too cold, it WILL DO SUMTHING BOUT IT.
ur body wud shiver, u wud go under the blanket,
and many other responses takes place.

so dat wut is causing ur body temp to rise up, thus causing fever.








n later when ur fever resides n ur getting better,

(assume dat uve manage to fight off the bacteria--->pyrogens decrease n decrease until theres none left)
ur setpoint in the hypothalamus go down to normal.
so now, ur setpoint is at normal,
but ur ACTUAL TEMPERATURE  is still abnormally higher than the setpoint.
so ur brain wud tell ur body,

''dude, ur too hot la. do sumthing please''
so then ur body wud respond by 
vasodilation, u wud sweat, ull throw away the blanket n so on,
so dat ur actual body temp wud fall.

dats y when ur getting better,
u feel so damn hot,
but ur actual temperature is usually around normal to slightly high.


bear in mind, during the middle of ur fever,
ur body temperature STAYS HIGH, 
but u will feel normal, not hot at all.
dats because ur body temperature matches the temperature of the setpoint.








fuh anyway.
im addicted to the Hush Sound. haha.
n im not alone.
ever since i played it loudly in the hall,
all of my housemates starts to humm this song all da tyme. haha.
~the sea's wine red, this is da lalalalalal...~
