On a very hot day， it can be hard to know what to do to feel good． If we run around， we may feel dizzyand sick to our stomachs． This is because our body can't get rid of the extra heat． However， if we just sit and do nothing， we may feel restless and bored． Are there things we can do to feel good when we are hot？ Yes ! Playing in water is one way to feel cooler． Of course， people with a pool， river ， lake or ocean nearby can play in the water very conveniently． People don't have these can still play in water too． Taking a cool bath or shower can feel good on a hot day． On hot days， you can lose two gallons（加仑） of water in one day， so many doctors agree that you should try to drink at least 16glasses of water to keep the water balance in your body．Mixing a little juice into your water is a good way to help you drink plenty of water． The food we eat also makes a difference in how we feel in the heat． Cold foods， such as ice cream and drinks with some ice can cool down our bodies． Fruits and vegetables are easy for the body and refreshing． Plan a healthy menu for a hot day．
