Hot Weather Can be Dangerous August 6, 2010

We love summer…we love to swim, play outside, go to the park, go fishing…you name it! Summer is fun. Summer is also hot, and that is wonderful as long as it is not too hot.

During the month of July, and so far in August, the weather has been very hot. The temperature each day has been 36 to 38 degrees centigrade. That is hot! And when the temperature is that high, you must be careful not to have  heat stroke or heat exhaustion.

When it is hot, we sweat. Sweating cools our bodies down. If it is really hot and humid, sweating may not be enough to cool us down and maintain our normal body temperature. Our internal organs, such as our kidneys, can be damaged if our body temperature rises too high. This is called  heat stroke.

Heat stroke can happen from being in the hot sun too long or being exposed to very high temperatures without a chance to cool down.

You will know you have heat stroke if:

  • you have an extremely high body temperature
  • your skin is red, hot and dry
  • your pulse is rapid
  • you have a throbbing headache
  • you are dizzy
  • you feel like throwing up
  • you are confused or faint

If you think you have having a heat stroke, find a cool place to sit down. If you cannot be someplace with air conditioning, find a place in the shade. Stay in the sitting position; loosen your clothes, put a cold wet rag on your head. Find a doctor and get medical help.

Heat exhaustion is also dangerous. It happens when you spend too much time in the heat and you don’t drink enough fluids.

You will know you have heat exhaustion if:

  • you are dizzy
  • have a headache
  • feel like throwing up
  • have stomach cramps
  • your breathing is shallow
  • your skin feels cool and clammy
  • your muscles are trembling
  • you are sweating a lot

Again, find a cool place to sit down. Loosen your clothes and drink cool water. Sit quietly until you feel better.

The most important things to do in such hot weather is to drink plenty of water or fruit juice; stay out of prolonged direct sunlight especially during the early afternoon when the sun is hottest; find ways to cool down a few times during the day; and do not over exert yourself during the heat – take everything just a little slower.

That’s why they call it, “The lazy, hazy, crazy days of summer.” You can have lots of fun, just be careful in the heat.

A sign of spring February 18, 2010

Do you know the name of these flowers?

When I was a little girl, in February my mother would tell me to listen for the spring birds. She said if I hear spring birds in the morning I would know that winter would soon be over.

There is another sign of spring that many people look for…the first flowers. For Valentine’s Day, I received a bunch of beautiful white flowers. I had never seen flowers like these, so fragrant and tiny and delicate. I was told that these are the first flowers of spring.

In America, we watch for the first flowers of spring also. Folklore says that the first flower of spring is the flower of hope. It is a symbol fo new beginnings and rebirth. 

There are a few different flowers we watch for to tell us that winter is over.  The daffodil is one of them. So is the crocus.

And we have a superstition about the first flower of spring. Read below and maybe you can watch and see when you see the first flower in Ukraine.

If the flower is found on a…
Monday – good fortune is approaching.
Tuesday – success will be achieved in higher goals.
Wednesday – wedding bells will ring.
Thursday – opportunities for small profits will soon arise.
Friday – wealth is heading your way.
Saturday – consider yourself warned.
Sunday – you are guaranteed great fortune over a long period.

Can you name these flowers?

From rain to snow… February 16, 2010

Last night, we went to bed to hear the rain falling on the roof. This morning, we woke up to snow. What happened?

That is easy….when the air is warm, such as above 0 degrees centigrade, moisture in the air forms rain. When the air turns colder, 0 degrees or below 0 degrees, the moisture freezes and turns to snow. 

What is snow? It is frozen water. It freezes in the air in tiny little drops and forms crystals. There is a lot of air in snow and that makes it lighter than water or ice. Rather than falling straight down from the clouds like rain, snow will often drift down like a leaf falling from a tree.

Sometimes the snowflakes are very large and heavy and wet. That happens because the little drops of water stick together high up in the sky before they form crystals.

And other times we have sleet instead of snow. That occurs because high up in the sky, the air is warmer than the air by the earth. The drops of water start out as rain but freeze as they fall to the ground. Those frozen drops of water become sleet.
