EgyptI am eager to know more about life at high temperatures as this is suitable for Egypt. I'd like to know how plants deal with that and how humans and other organisms deal with it too.
Four O'Clock FlowersI have noticed that my four o'clock flower plants have acclimatized with high temperature when the tree that used to shade them was pruned and they suddenly received a higher doze of sunlight than they were used to. During the following season they managed to tolerate the heat much better. I believe the mulching I have added to them helped make them tolerate the extra heat yet I believe their ability to acclimatize did have a profound effect as well.
SunstrokeHumans also can get a sunstroke if they are exposed to excessive heat, through strong direct sunlight, for an extended period of time (a number of hours). This shows how the body fails to deal with the excessive heat and how its cooling system has a limit after which it can break down. Of course keeping hydrated by drinking lots of water helps in avoiding such sunstrokes and can also help in relieving the effects of a sunstroke after it hits.
That's why when running they advise us to drink lots of water before, during and after the run itself. That's why I get really tired and loose energy after such a running day in the sun particularly if I do not consume enough water.
Human CellsI remember at school that in biology I heard that cells of human tissue would solidify at temperatures above 50 degrees Celsius. This fact was pretty interesting for me, as for me intuitively things liquify at higher temperatures rather than solidify. The teacher explained it by making an analogy with the white of an egg, it solidifies when heated. This notion was scary to me, as it signaled the death of human tissue at such high temperature. I wounder if this piece of info was really true. I would like to check it out and know more about how this process works and consequences and all.
SinaiI wonder what interesting wild plants would be found in Sinai that withstand such high desert heat and low availability of water.
Fire-free EgyptIn Egypt we do not usually have high risks of fire despite the high temperatures and also low humidity. The reason behind this is mainly that we do not have forests in Egypt. Houses also are almost never built using wood (perhaps also due to the lack of presence of forests in Egypt).
Fire-surviving PlantsIt is interesting to realized that some plants would not regenerate or propagate (seeds would not sprout) except after experiencing very high temperatures of a fire.
SterilizationThat's why we use very high temperatures to sterilize something. Such high temperatures can kill harmful microorganisms.
SolarizationThis also explains the concept of soil solarization that is sometimes used in agriculture to sterilize soil from 'harmful' microorganisms.
Also water solarization is a method by which water can be purified by exposing it to direct sunlight for a specific period of time.
I have also heard before that direct sunlight as it falls for a period of time on streams of water can break down pathogens and help purify the water.
