The best AC temperature for sleeping is typically between 60 to 67 degrees Fahrenheit.

To sleep comfortably during the scorching Las Vegas summers, it is essential to invest in the best AC system available. With an efficient air conditioning unit, you can ensure a cool and pleasant environment in which to rest. Whether you opt for central air conditioning or portable AC units, having reliable cooling equipment will help prevent sleepless nights caused by excessive heat.

To ensure optimal sleep conditions, it is recommended to set the thermostat between 60 and 67°F, with 65 degrees being the ideal temperature for sleeping, according to the Sleep Foundation. This range allows the body to experience a slight decrease in core temperature, signaling the body that it is time to rest. To achieve the best AC settings for a good night’s sleep, aim for a temperature within this range.

To ensure optimal nighttime temperature settings for your HVAC unit, it is recommended to utilize the sleep mode feature on your AC thermostat. This function automatically adjusts the temperature at a specified time, eliminating the need for manual adjustments. If your current thermostat lacks this capability, upgrading to a smart thermostat is highly advisable. Smart thermostats offer convenient temperature programming options while enhancing energy efficiency, making them the best choice for AC temperature control.Best AC Central Air Conditioning

To achieve the best AC performance and indoor comfort, it is crucial to consider humidity levels. Maintaining a relative humidity between 30 and 50% is recommended by experts. However, in areas like Las Vegas, where relative humidity tends to be low, it may be necessary to install a whole home humidifier to reach the desired comfort range. Additionally, for optimal nighttime temperature settings, utilizing the sleep mode feature on your AC thermostat is advised. If your current thermostat lacks this functionality, upgrading to a smart thermostat is highly recommended. Smart thermostats not only offer convenient temperature programming options but also enhance energy efficiency, making them the ideal choice for precise AC temperature control.

How to Sleep in Hot Weather without AC

If you are unable to access air conditioning, there are alternative methods to improve your sleep in hot weather. Here are some steps you can take to achieve better sleep without the use of AC:

  1. Opt for light blankets. If you must sleep with a blanket, opt for a thin sheet, preferably made of cotton or another breathable material.
  2. Freeze your top sheet. A few hours before bed, put your top sheet in the freezer. This will ensure the fabric is cold when you’re ready to hit the hay. 
  3. Circulate the air. Moving air is critical to staying comfortable in a hot bedroom. You can use a ceiling, box, or oscillating fan. Fans speed up the sweat evaporation process as you sleep and provide white noise, which can also aid in sleep. If you’re comfortable sleeping with the windows open, use a fan in front of an open window to encourage maximum airflow.
  4. Wear lightweight clothes. Lightweight cotton or linen pajamas can help you stay comfortable while allowing your body heat to escape more quickly than other fabrics, such as polyester. 
  5. Sleep on the lowest level of your house. Try sleeping on the lowest level of your house (preferably the basement, if you have one). Heat rises, so the higher levels and upstairs rooms will be the hottest places in your home. 
  6. Keep water nearby. A few sips of room-temperature water can help cool you down. It may seem contradictory, but your body works harder to process cold water, which warms you up. Room-temperature water is easier to process and won’t cause extra internal heat. 
  7. Place a cool, wet washcloth on your face or neck. You lose the most heat through your head and face. Putting a damp cloth on your forehead or neck can encourage heat wicking from these areas. 
  8. Limit exercise hours. You increase your body temperature when you exercise. It’s best to exercise early in the day so your body can cool down again before bed. 
  9. Turn down your humidifier. Dry heat is generally more tolerable than moist heat, which often feels hotter than it is. Las Vegas is rarely humid enough to need a dehumidifier, but you can turn down or skip running your humidifier at night.
  10. Keep the heat out during the day. Close blinds and curtains while the sun is up to keep your home as cool as possible. Open your windows at night when the outside air is cooler than the air inside. This will also improve air circulation.
