Greetings to the entire community of steemit today my presentation, for the theme of natural forces is about "LAS OLAS DE CALOR", let's study a bit of the subject...

A heat wave is a time where it will be too hot, and with excessive moisture. The system of alert on heat is in charge to warn, when these periods will make life in certain regions. Heat waves have 4 levels:

:: Green =
Minimum state of surveillance during the summer. Without danger on the health of the population.

:: Yellow =
Heat waves can be dangerous, especially for risk groups, infants and young children, people over 65 or those with chronic diseases -hypertension, obesity and / or diabetes-. It is reached when the thresholds are exceeded in the maximum and minimum temperatures in a city.

:: Orange =
Heat waves can be very dangerous, especially for risk groups. It is declared when the heat wave continues in time and thus increases the excess heat.

:: Red =
Exceptional cases of heat waves. They can affect all healthy people, and not just risk groups.

EFFECTS ON HEALTH:

The heat wave can be predicted a few days before it is unleashed and the alert level will mark the intensity of the necessary prevention measures. The consequences for health can be of greater or lesser severity, depending on the general state of health of each person, the type of alert and the preventive measures that are taken, as the case may be: Heat stroke or insolation / Body dehydration / Decay or weakening / Fatigue / Headache / Lack of appetite / Insomnia / Accelerated pulse / Cramps / Muscle aches / Exhaustion / Abundant perspiration / Syncopal dizziness / Low pressure / etc.

Heat waves can aggravate or enhance the emergence of a variety of diseases and health impacts. For example, it can cause myocardial infarction and especially, diarrheal diseases. Diarrhea is the second cause of death for children in the world (mainly due to dehydration). That is why it is important to be alert if there is diarrhea especially in babies and small children.
