The environmental stress I chose is
cold climate. When homeostasis is being disturbed, it can cause environmental
stress that negatively affects the life of humans. Ways that negatively affect
humans are by causing harm to their health.
The Body begins by shivering to maintain homeostasis, but shivering can
be uncomfortable and get annoying after a while. When the body is in the process of cooling
down it’s a critical part, it can result in injures such as non-freezing,
Frostbite, or hypothermia which can be deadly. Vasoconstriction, which narrows the blood
vessels also can be considered a natural response from your body to keep your
body warm, but can also cause damage if it’s permanent. Shivering is a
short-term adaption that we as humans use when confronted with cold
climate. Our bodies begin to shake
during cold climate to try to warm the body back up; our body’s muscles have
spasms that help to generate heat for a short period of time. A Facultative
adaption that humans react to the cold climate is vasoconstriction. When the
blood vessels constrict, the flow of blood is restricted, therefore retaining
body heat. The development adaptation that humans use in response to cold
climate is the body, shape and size. People that live in cold climates, have a
tendency to be over weight to keep in their body heat. When the fat is distributed around human’s mid
section it tend to keep the vital organs warmer and uses the fat for
energy. Culture adaptation that we see
in humans that live in cold climates is their clothing. The humans that decide to reside in cold
climates use heavy clothing, such as jackets, pants, scarfs, and gloves. When studying human variation there are many
beneficial outcomes, for instance we get to see how people that have adapted to
the cold could survive, when being compared to someone who isn’t. Adaptation of a group to there surroundings
physically inorder for them to survive become what I consider a race.
