Running the air conditioner nonstop might be the easiest way to stay cool, but it’s also one of the fastest ways to drive up your electric bill.

In a recent Reddit thread, one person asked a simple question: how do you stay comfortable in the heat without relying so heavily on AC? The responses quickly filled with practical, low-cost ideas, many of them surprisingly simple, and some that people swear by after years of dealing with hot apartments and tight budgets.

What stood out most is that staying cool isn’t just about lowering the temperature; it’s about managing heat before it builds up and cooling your body more efficiently.

Here are some of the most talked-about strategies.

Block the Heat Before It Gets Inside

One of the most repeated tips was also one of the simplest: keep sunlight out.

People emphasized closing blinds or using blackout curtains during the day, especially on windows that get direct sun. Several said this alone made a “huge difference,” with some even describing their homes going into “cave mode” to keep temperatures down.

Others suggested taking it a step further with thermal curtains, reflective window film, or even temporary insulation to reduce the amount of heat that enters in the first place.

Use Fans Strategically—Not Just Constantly

Fans came up in almost every response, but not just as a basic fix.

Instead of trying to cool an entire space, many people recommended aiming a fan directly at your body, especially while sleeping. Some said this allowed them to raise the thermostat by several degrees while still feeling comfortable.

Others suggested creating airflow through the home, such as placing fans near windows to pull hot air out and draw in cooler air. The goal isn’t just movement, it’s direction.

Cool Your Body, Not the Whole Room

Another common theme was focusing on personal cooling rather than trying to chill the entire apartment.

People shared surprisingly effective tricks like placing ice packs or frozen water bottles near the body, especially around the neck, under the arms, or even between the legs, to cool down quickly. Others mentioned wrapping a cold cloth around the neck or wrists, which can lower overall body temperature faster than expected.

Even something as simple as drinking cold water or rinsing your arms with cool water was mentioned as a quick way to feel relief.

Try “DIY Cooling” Methods

Some of the most creative responses leaned into low-tech solutions that have been used for generations. One popular method was to use evaporative cooling, such as draping a damp towel or sheet over yourself and blowing a fan across it. As the water evaporates, it pulls heat away from the body.

Others suggested placing a bowl of ice or a frozen jug in front of a fan to create a makeshift cooling effect. While it won’t replace AC, many said it helps take the edge off in smaller spaces.

Take Advantage of Cooler Hours

Some people recommended opening windows at night or early morning when temperatures drop to bring in cooler air, then sealing everything back up during the day to trap it inside.

This works best in areas where nighttime temperatures dip, but when they do, it can significantly reduce the need for AC.

Focus on the Bedroom for Better Sleep

Sleep was one of the biggest concerns in the discussion, and many people were willing to compromise. Instead of cooling the entire home, several suggested focusing on just the bedroom at night. Options ranged from using a small window unit to simply lowering the AC briefly before bed and then turning it back up.

Others relied on fans, lightweight bedding, and minimal clothing to stay comfortable without overworking the system.

Small Adjustments That Add Up

Beyond the bigger strategies, a lot of smaller habits came up too, like avoiding heat-generating appliances during the day, keeping doors and windows sealed tightly, and reducing humidity when possible.

Individually, these changes might not seem like much. But together, they can noticeably reduce how hard your AC has to work.
