Water heaters in homes that are too hot are the most common cause of the smell.

While you can’t be sure what causes it, it is possible that the heater is leaking, or the air conditioner has overheated, said Jennifer Lauterbach, a registered health educator who works with people in nursing homes.

“It’s not that people don’t want to be outside, but that they want to go to the pool,” Lautersbach said.

Lauteringhaus, who also works with patients in nursing home homes, recommends using a thermostat that has a “quiet” setting, and that it is turned off when not in use.

If the air conditioning fails, the heat should go to your pool, not your bedroom, she said.

If you’re concerned, Lauterbus recommends keeping the thermostats on for at least 30 minutes before returning them to their default setting.

You can also use a non-air-conditioning device to cool the home.
