You do not have to do anything more energetic than simply move through your day to be exposed to a multitude of environmental toxins from Airborne Pollutants, EMF's (Electromagnetic Fields), Endocrine disruptors to Pesticides and Heavy Metals. While we all carry these toxins in our bodies to a greater or lesser extent, some groups such as children, women (especially pregnant) and elderly are more affected than others.
In hot weather, coolers can prevent heat stroke, dehydration from excessive sweating and other problems related to hyperthermia. Heat waves are the most lethal type of weather phenomenon in developed countries.
Air conditioning (including filtration, humidification, cooling and disinfection) can be used to provide a clean, safe, hypoallergenic atmosphere in hospital operating rooms and other environments where proper atmosphere is critical to patient safety and well-being.
There are many ways to control air around you but one of the oldest is simple evaporative cooling with or without added chemical or biochemical pre-treatments and filtration stages.
They are often the best substitute for air conditioning units. Unfortunately they are sensitive to climate because of the way how evaporative cooler works which means they are recommended only to be used in dry, hot climates.
Appart from that evaporative coolers (EC) have many advatages: cheap to buy and run (fan is the only moving part or replaceable filters), silent, EC won’t dry out the air so it is hlepful to skin and eyes and EC units not have much CO2 emitting. Those who suffer from allergies asthma may find that evaporative coolers help them to feel better.
Unfortunately not all of us live in dry and hot climate to enjoy advantages of evaporative coolers (EC) so we often must consider Air Conditioning units (AC). Contrary to EC units Air conditioning (AC) is the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. This is done in a very similar way as house refrigerators which take away heat from our food by using heat exchange fluid.
For Heating, ventilation and air conditioning we use HVAC systems. Air conditioners often use a fan to distribute the conditioned air to an enclosed space. Air conditioning systems act as heat pumps by using refrigeration cycle to produce heating instead of cooling in the indoor environment. Air-source heat pumps are more popular in milder winter climates where the temperature is frequently in the range of 4–13 °C (40–55 °F), because heat pumps become inefficient in more extreme cold.
