Sweaty Back Syndrome: Its Causes, Symptoms, and Cure


Do you, or someone you know, suffer from Sweaty Back Syndrome?

If so, you’re not alone. It’s a condition that affects millions of Americans each summer.

Here’s how you can tell if you’re affected, and what you can do about this unfortunate and widespread problem.


Sweaty Back Syndrome, or SBS, is caused by driving a car with a broken or undercharged A/C system. When an air conditioner is low on refrigerant, it loses its ability to cool the air in the car. And since a car interior can get fantastically hot on a sunny summer day, a person’s body has to sweat profusely in an attempt to cool off. Since the person’s back is pressed up against the car’s seat and has no air to dry it off, the clothing on their back becomes soaked with sweat.


The main symptom of Sweaty Back Syndrome is, not surprisingly, a sweaty back. Though it’s often accompanied by sweat in other areas, such as the ever-present underarm area, what sets SBS apart is that the back becomes noticeably wetter than the front.

Other symptoms include:

  • White stains left on dark clothing once the sweat has dried.
  • Excessive thirst, and a pronounced craving for “electrolytes.”
  • General irritability, especially on sunny days or when traffic is moving slowly.
  • Nervousness or avoidance whenever co-workers start discussing whose car everyone can pile into on the way to lunch.
  • Always wanting to carpool, but never willing to drive for said carpool.
  • An unfortunate smell.
  • Regularly talking about moving somewhere cooler, like the North Pole.
  • Complaints about the high cost of auto mechanics.
  • Only going out on a date when the forecast calls for temperatures below 72 degrees.
  • Buying unnaturally large quantities of ice.
  • Only being happy when it rains and everyone ends up soaked.
  • Hating summer, while openly being fond of “cold season.”


As with all ailments, the key to eliminating the symptoms is to overcome the cause. In this case, the solution is to get your car’s air conditioner working again.

In most cases, you can recharge a car’s air conditioner and get it cold again with a single can of A/C Pro. It can save you a considerable amount of money, it’s fast (taking only 5-15 minutes), and it’s simple enough that pretty much anyone can do it—even if they have a sweaty back.
