Brain damaging habit 2 of 10: Sleep Deprivation

We spend roughly a third of our lives asleep, but sleep is a remarkably productive time for our brain. Sleep allows the brain to rest from the day’s activity, repair itself and prepare for the next day’s activity.
Inside the skull, the brain sits in a clear fluid that acts as a buffer or cushion called cerebrospinal fluid (CSF). During sleep, the space between brain cells expands significantly and more efficiently allows CSF flow between them. The CSF acts as a waste removal system for the brain as it facilitates the clearing of toxins generated throughout the day’s activity. The brain clears out toxins much more rapidly while we’re asleep than when we’re awake. These toxins include β-amyloid protein, a precursor for the plaques found in Alzheimer’s disease, and the very destructive free radicals (by-products of oxygen metabolism).

A habit of not getting enough sleep each night will therefore accelerate the death of brain cells. Plan on getting at least 6-8 hours of sleep each night.

ON TRAVELLING FROM CHIPATA TO CHADIZA

This is a first for me....on a hot and sunny afternoon like today, I never knew that a taxi could accomodate 7 people. Three people in front, with one having the gearbox in between his legs. We at the back are jam-packed between the doors, bedraggled by our own 'armpit grease' on a long winding dusty gravel road. But the master says "Occupy till I come."

TAKE NOTHING FOR GRANTED

What is it about Friday that makes us all tired? Or makes me tired? It was 1:30 pm by my watch and had only been in theatre for slightly over 4 hours. I was helping the anaesthetist pack the instruments after our last scheduled case when the attending surgeon came in. Seemed like our day wasn’t done yet. The anaesthetist too was tired but he gets paid anyway and I don’t. Am a student though and need to maximise every opportunity to learn too… I had the option of leaving and going to have lunch and rest (am human too) or staying back to learn some more..…this never ending internal conflict, this duel loyalty idea, at times just takes a toll. The patient was a 5-day old female neonate born with an imperforate anus-simply, the bottom end was closed. Sadly, this malformation doesn’t usually occur in isolation but is associated with heart, urinary, tracheal and oesophageal defects among others. Quickly, my thoughts were drawn to think of the little’s girl’s future outlook. Here I was in...

WHERE IN LIES YOUR HOPE FOR TOMORROW?

Sometime ago whilst on the hospital ward, I was challenged by woman whose son was due for surgery later that night. The 17 year old boy had a massive tumour on his right arm that was roughly the dimensions of a 5 litre container. She asked me to ponder on a series of questions for which I had no immediate answers. “If indeed God is after our own good, why has He chosen me amongst all the women to have a child who has this misfortune? What future does He have planned for my son because he hasn’t been able to go to school all his life? Why does evil seem to be selective on whom it befalls?” I cant remember my exact responses but one thing was true. This was a woman in distress. Sadly, I went out to look for her on the ward the following day but never found her. This later reminded me of an experiment. The Norwegian Field Rat (mbeba yaku Norway) is known for its endurance. The University of California Berkeley once conducted an experiment to determine how long the rat could endure. The...
