Why did I giggle?

Why did I giggle?

Having quivering in my voice,

speaking hurriedly, broken words,

finding it difficult to convey...

And I noticed the changes, 

fingers getting stiff each moment,

getting chills all over my body,

I finally realized, it's getting colder. 

Sitting in my workspace,

getting involved, discussing subjects,

I never have thought to experience...

This curious condition, at that place.

With a little tweak, or by accident,

air temperature reduced by numbers,

and I shivered, getting goosebumps, 

opening my mouth...just to laugh. 

It's indeed an intriguing situation,

known too well, from my childhood,

in wintry showers, or getting drenched,

visiting mountains, or morning trails...

Like a natural response of my body,

getting triggered, making me fluttery,

I tried to gain control, of my body,

only to be overpowered, laughing hysterically. 

Those were the fun times,

but now, I have to be serious,

still, I needed some explanation, 

it does make me curious.

Not so common, varying reasons,

some identify it as shock response,

a sudden change of surrounding temperature, 

stimulates release of adrenaline in our body. 

It could also be sensory stimulation, 

creating a tickling or tingling sensation,

Or could be from endorphin release,

producing feelings, of euphoria & happiness.

Then again, it's a psychological conditioning, 

when brain finds cold as something amusing,

these explanations, only made me confused... 

Why did I giggle? I kept wondering.
