Humans can adapt to many different situations. It may take a few days to acclimate to the weather at your trip’s destination, but you get used to the new situation. Physiological adaptation occurs with the senses. If you hear a repeated sound your brain will adapt to it and will start to filter it out. You will start to notice it less and that allows you to notice other sounds. The same occurs when you encounter pungent aromas, after a short period of time the smell will be less noticeable. Something similar occurs when you expose yourself to differences in temperature, e.g. sauna or ice bath.
This adaptation process will work to a certain extent and depends on your body’s coping ability. If your body is compromised in any way then your ability to adapt will be affected. Serious illnesses can lead to an inability to handle these situations. There is a limit to what you can cope with. This might be changed with training. Repeated exposure to the stimulus will lead to changes in the body and mind.
Adaptation and coping are not purely physical and the mind has a big part to play. I have looked after many people who have survived for much longer than I thought would be possible. I have often remarked that they are kept alive by sheer force of willpower. A strong mind will sustain a physical body much longer than expected. People with strong beliefs or reasons to stay alive may also outlive their prognoses.
This inner strength lies somewhere deep inside the individual and their determination may have resulted in many successes in the past. These people might be described as stubborn, and like most personality traits people will stay true to themselves right until the end. Sometimes people have to actively let go before they can finish their current life. One person said, “There’s too much love around me, I can’t leave when there is so much love.” That’s why some people will wait until there is no one around before they can die. They didn’t want anyone to witness their very end.
We all make choices. Survival is not mandatory. It is an active choice that many of us make. Adapt or die. It’s not that simple. Even coping with a change in time zone can be a challenge as I am finding out today. Yawn.
