I know it is summer and it is hot, but remember- people a hundred years ago didn't even have air conditioning units! They didn't even have electrical fans! And guess what? They led happy, productive lives. Of course, I'm not asking anyone to not turn on their AC for the summer. All I think is necessary is to use common sense. For most people, 80 degrees indoors when it is over 100 outside isn't too bad. No need to crank down the thermostat to below 70.
There are various ways to cool down. Obviously, wearing lighter, thinner clothes helps, such as shorts and tanktops. Taking colder showers will help cool you off. Drinking ice cold water definitely will chill your system.
Other strategies: remember to turn off the AC whenever you leave home, or at night when it is cooler and less humid. If you have different units for different rooms or floors, it is most effective to only turn on the unit of the area in which you will be staying. If you can control the air flow into rooms, turn off the AC in rooms you rarely use, such as a spare bedroom or a formal dining room.
You can save a lot on your utility bills with these simple changes. I know people who spend several hundred dollars a month just because of the AC! Now, doesn't it seem better to endure a few degrees higher temperature in return for that money? Not to mention the benefits of using less fossil fuel!
