Light and Darkness/Shadow in Greek Mythology

In Greek mythology, there are multiple personifications of light. Helios is the Titan god who represents the sun and drives across the sky with his chariot. This golden chariot was said to carry the sun across the sky from east to west. This is how the phenomenon of the sun rising and setting is explained. Apollo is the god of light and the sun. He was thought to bring warmth and the sun’s light to men. Eos is a Titan goddess and represents dawn. She has total control over light. Her name derives from both Sanskrit and Latin sun goddesses. Lastly, Hemera is the goddess of daylight.

Warm and Cold Blooded Animals

After reading the Heat and Cold section in our reading I was most fascinated by the warm blooded and cold blooded animals. Humans are classified as warm blooded animals even though sometimes we can be considered “cold blooded” meaning lacking or showing feeling. Humans are considered warm blooded because we can keep our temperatures stable through metabolic adjustments even when it is cold. Warm blooded animals tend to survive in low temperatures by shivering or burning body fat. Examples of warm blooded creatures include birds and mammals. Cold blooded animals can maintain their body temperatures from the outside like for example using heat from the sun. The other day I actually saw a cold blooded animal in action. I was walking to my car and a snake was laying out in the middle of my driveway just soaking in the sun. Examples of cold blooded animals include invertebrates, fishes, sharks, frogs, snakes, and crocodiles.

Hyperthermia and Hypothermia

Hyperthermia and hypothermia are two extreme conditions associated with heat and cold. Hypothermia is when the body drops to dangerously low levels, and hyperthermia is when the body rises to dangerously high levels. Both are the complete opposite of each other, but carry the same amount of life-threatening risk. These are examples of negative effects of heat and cold, however, heat and cold can also prove to be very beneficial in other ways.

One condition of hyperthermia is heat stress. This may then lead to heat exhaustion and a heat stroke, in which people can experience dizziness, weakness, nausea, thirst, and headaches. To combat this, drink lots of water and provide your body with electrolytes. Heat syncope may also occur. This is when blood pressure decreases and the flow of blood to the brain is dramatically reduced, therefore leading to fainting. Other conditions of hyperthermia include heat cramps, heat edema, and heat rash.

Hypothermia is when your body loses heat faster than it can produce it. It occurs when body temperatures drop below 95°F. If hypothermia is not treated immediately, the heart and respiratory system become extremely susceptible to failure and eventually cause death. Shivering is the body’s initial response to cold temperatures. It is an attempt to produce heat and make the body warmer. If this method fails, more symptoms will show such as slurred speech or mumbling, slow, shallow breathing, weak pulse, clumsiness or lack of coordination, drowsiness or very low energy, confusion or memory loss, and loss of consciousness.
