On Tiredness

Posted on by Jinavie

“I’m tired because I didn’t get enough sleep last night.”
“I’m tired even though I’ve slept enough last night.”

“I’m tired because I have too much work to do.”
“I’m tired because I’m finishing up work.”

“I’m tired because I haven’t had coffee yet.”
“I’m tired even though I’ve drank coffee.”

“I’m tired because it’s Monday.”
“I’m tired because it’s Tuesday.”
“I’m tired because it’s Wednesday.”
“I’m tired because it’s Thursday.”
“I’m tired because it’s Friday.”

You aren’t tired when you are at a concert.
You aren’t tired when you’re fully immersed in a movie.
You aren’t tired when you’re on a date with someone you love.
You aren’t tired when you are doing something that you enjoy.

If you feel tired every day, then that is a sign you are doing something that you hate.
Instead of making another cup of coffee, try finding something that you love doing.

Your tiredness will simply melt away.

Scrubs

Posted on by Jinavie

Scrubs is the uniform that surgeons, anaesthetists, emergency department doctors and nurses wear for the freedom and mobility required in activities such as surgery and CPR. Also, since it is owned and washed by the hospital instead of being privately owned, it is more hygienic and helps prevents infections. A noticeable trait of scrubs (and also surgical gowns) is that almost every hospital uses a shade of blue or green instead of white. Why is this?

The reason being, looking at a surgical scene for a long period of time can cause eye fatigue and afterimages due to the redness of blood and organs. Afterimage is a phenomenon that occurs when the retina becomes insensitive to a strong colour and instead making the complementary colour stand out more. Ergo, a surgeon looking at blood and organs for too long will see afterimages of a blue shade, which may cause accidents to happen as it overlaps on white surfaces or the surgical field. Clothing of blue or green colour neutralises the afterimage and is much easier on the eyes, reducing the fatigue. Lastly, blue-green colours have a calming psychological effect, which helps in a high-tension, stressful environment such as in an operating theatre.
