How To Keep Cool in Summer Heat 

webmaster@keepingmecool.com 

 

You may be surprised to find out that you can be cool 

and comfortable in the summer heat   

 

Fortunately there are ways to alleviate the effects of the 

Summer heat. What follows is some information on  

Products to help keep you cool. 

 

Cooling Vests will keep you cool, but different vests are 

suitable for different situations. 

 

1. Evaporative Cooling Vests are best suited for use  

outdoors, and on days when humidity is not to high.  

These vests work on accelerating your body’s natural 

evaporative cooling. The vests are soaked in water.  

As the water evaporates your body temperature is  

reduced. 

 

These vests are relatively effective. They are cheaper  

than other vests. Prices start at about $30. 

 

On the downside they are not suited to being worn  

underneath other clothing. This will slow down the  

evaporative effects. Your clothes will be wet after  

wearing these vests. Evaporative vests available at

2. Phase change vests these vests use packs that you  

freeze. The pack is filled with a gel made of Hexadecane. 

The pack melts at 18 degrees. The high melting point is 

very effective at keeping your body temperature at a  

natural level. These vests are very effective indoors and  

outdoors. They do not really on evaporation to keep you  

cool so are fine to wear under clothes. You will stay dry.  

 

The only problems with these vests is that they are  

expensive $180 plus. In addition to this you will need two 

or three sets of packs to get you through the day  

costing around $100 plus per set. Phasechange vests  

available at http://www.coolsport.net 

 

3. Personal Ice Cooling System (PICS) are the most  

effective by far. They are also the most expensive about  

$1800. They work by pumping iced water around a vest  

using a small pump. The pump is powered with rechargeable  

batteries. The water is cooled by ice packs. One of the  

advantages is that it uses regular ice in packs and as long 

as you can find a freezer or ice your in business.  

 

These vests will keep you cool in any conditions. They are  

even used by the military. They are suited mainly for  

working enviroments in the heat. They require a type of  

back pack of tobe worn. This system weighs of approx 8lb. 

They are very effective though at keeping you cool in the  

heat. (PICS) available at

4. Cooling bandanas and neck ties use highly  

absorptive polymers that are sewn inside neckties and  

bandanas. When soaked in water they absorb water and 

swell up. They are then worn and help a little to keep you 

cool. They use evaporative cooling. They can also be  

placed in the refrigerator before use for added cooling.

5. Lastly guys as simple as it may seem try to have plenty 

of cold water handy. If you drink water before you start to  

become dehydrated you feel much better.
