the summer sun is on my mind this morning. It is the first time in quite a while that I have spent my day in the sun. I am very thankful for the warm sun and the fact that it has reminded me how much I miss my garden.
The summer sun is a major factor in the cooling effect on our skin. It is also one of the things that causes us to sweat a lot. As we sweat, the moisture evaporates from our body and the sun’s rays heat our face, causing heat exhaustion. In general, the hotter we are the faster we sweat. A person with a higher than average sweat rate has a higher than average chance of heat exhaustion and dehydration.
I’m not sure why heat exhaustion is such a big deal if the average person can survive a very mild summer. I suspect that the average person does not sweat as much, and thus gets plenty of air conditioning. If you’re not sweating and getting plenty of air conditioning, you’re not going to die.
Heat exhaustion is a medical condition (also known as heat stroke) caused by a person’s body overheating. When your body gets too hot, the body’s heat-regulating organs (like your brain) start to shut down to prevent further heat stress and damage.
Heat stroke is the body shutting down to protect itself from heat stress but also because it is so uncomfortable. Because the bodys’ heat-regulating organs are shut down, the body is unable to cool itself off. In that moment of shock, you can die.
The heat-regulating organs of the body are the brain, kidneys, and the sweat glands that control body temperature. When all the body’s heat-regulating organs shut down, the body cools down and becomes dehydrated. This can cause severe heat exhaustion. In extreme cases, your body can become so cold that it stops sweating and becomes totally ineffective as a heat-sink.
Sounds like the heat-regulating organs of the body have shut down, we know it’s going to happen, but the body is unable to cool itself off. The result is that your body is frozen. The heat-regulating organs of the body are the brain, kidneys, and the sweat glands that control body temperature. When all the bodys heat-regulating organs shut down, the body cools down and becomes dehydrated. This can cause severe heat exhaustion.
In the same vein, our bodies can freeze. If you have a chronic condition, such as diabetes or heart attack, you may freeze. Your body can’t cool itself off all at once, and if you have one of these conditions, your body can only cool down for a few minutes before it returns to a state of dehydration.
Heat exhaustion and hypothermia are two of the worst ways to get dehydrated or freeze. Dehydration can be life threatening, especially for those with heart disease. If you take the time to get proper and ample fluids, your body will start to heat back up and you will be able to continue to work, exercise, or enjoy a decent meal. Hypothermia occurs when you are unable to heat up or cool down after the heat-regulating organs are shut down.
The most important thing you can do to lower the risk of hypothermia is to get a good night’s sleep. A warm, dry environment is also important. The heat loss from every sweating or breathing will cause you to become hypothermic. The coldness in your body is also critical. If you are hot, your body thinks it is cold, and will heat itself up, and if you are cold, your body thinks it is hot, and will cool itself down.
