Circadian rhythms are physical, mental, and behavioral changes that follow a daily cycle.
They respond primarily to light and darkness in an organism's environment. Sleeping at night
and being awake during the day is an example of a light-related circadian rhythm.
The funny thing about life is that it’s temporary; that is to say, temporary in the ‘temporal’
sense of the word, meaning that all living things and all that we do are subject to the precepts
and effects of time.”
—Lansing McLoskey, Theft
Though as " Childs play" people had volunteered for wintering in Antarctica ,The leader
selected Col Ganesan did not take it lightly.
History was full of examples about the "Physical,mental and psychological battle " the Antarctic
winter would cause amongst the unprepared team.Depression and mental dis order amongst the
wintering team can happen if the team members individually did not prepare well.
The team leader not only keep himself fit,but also thoroughly understands the psychological battle
he will be fighting with nature and non co-operating members.
The body’s internal timekeeping system is an under-recognized but highly influential force in behaviors
and emotions including anger and reactive aggression. Predictable cycles or rhythms in behavior are
expressed on several different time scales such as circadian (circa diem, or approximately 24-h rhythms)
and infradian (exceeding 24 h, such as monthly or seasonal cycles). The circadian timekeeping system
underlying rhythmic behaviors in mammals is constituted by a network of clocks
The Polar Night and 24 hours sun will certainly disturb the human body rhythm and create confusion
amongst members.
Antarctica is a mysterious continent having extreme nature's hazardous conditions.
Human body faces a new challange to adjust to the external conditions.
when it gets dark melatonin is secreted and that enables sleep.Sleep ,therefore is co ordinated
by the internal clock and external changes. sleep is an important factor to keep the human body
in a healthy condition.
A healthy entertainment,inter action between members ,Healthy food etc are very important factors when
the team is in isolation for a long period.Going to Antarctica on a National mission is not like
routine assignments.Even though the members may or may not have the pride,the leader must certainly
have it and demonstrate in his every activity.

En route they meet the Russian team from "Novolazaravskiya "
Maitree is about 85 Km from
Dakshingangotri and depending upon weather it may take 2-3 days to reach.
They drive over frozen lakes .
The first dozer to reach Maitree. Far to the right is the survival hut constructed during 2nd Expedition.
