What products are good for staying cool without AC?

According to the Centers for Disease Control and Prevention, extreme heat events cause mild to deadly health complications. To help people across the nation better prepare for these unhealthy conditions and prevent heat-related illnesses and death, the government has recently launched heat.gov. If you do not have an air conditioner, heat waves are dangerous because your body has no chance for relief. We'll go over how to stay cool without AC in these relentless high temperatures and the products you need to do so, including the Eclipse Fresno Modern Blackout Curtains approved by the BestReviews Testing Lab.

Why is heat so dangerous?

According to the Mayo Clinic, to function properly, the human body must maintain a core temperature between 97 and 99 degrees. Once the body drops below or rises above this temperature, it invites various illnesses. To maintain this functional core temperature, the weather needs to be roughly 82 degrees.

When the body’s core temperature rises, blood is diverted from vital organs and directed toward the skin to help release internal heat. Additionally, the water in your skin is excreted as sweat. To evaporate, it requires energy in the form of heat. With limited blood flowing to vital organs and a rapidly diminishing water supply, your body can quickly fall into a life-threatening crisis.

What are the symptoms of heat-related illnesses?

Both external and internal heat is a problem. Therefore, it is important to stay hydrated and wear breathable, moisture-wicking clothing. Additionally, heat-related illnesses have an immediate or cumulative effect on an individual, with symptoms intensifying over several days.

The primary symptoms of heat-related illness are:

  • Heavy sweating
  • Muscle cramps
  • Thirst
  • Mild shock
  • Dizziness
  • Nausea
  • Weakness
  • Unconsciousness

Heat exhaustion vs. heat stroke

It can help to keep these two heat-related illnesses clear in your mind by remembering that exhaustion is something that builds up over time, while a stroke is something that strikes suddenly with a substantial impact.

Heat exhaustion

With heat exhaustion, the body becomes fatigued from trying to maintain its core temperature. An individual suffering from heat exhaustion requires help to maintain their body heat. This is accomplished by moving them to a cooler area and replenishing fluids.

Heat stroke

Heat stroke happens when the body has lost the battle and your core temperature rises. This can happen suddenly or be the result of prolonged heat exhaustion. It is a life-threatening illness, so immediate medical attention is required. While waiting for help to arrive, get the person out of direct sunlight and try to cool them down with whatever means is available.

What are some strategies you can employ to stay cool during an extreme heat wave?

The key factors to staying safe during extreme heat are:

  • Be aware of the temperature and humidity: Be sure to check the weather in your area before departing.
  • Avoid going outdoors, especially for prolonged periods: If possible, don’t stay outside in extreme heat to prevent heat-related illnesses. 
  • Remove yourself from dangerous environments, such as a car interior: Cars quickly heat up to dangerous temperatures and objects within a car get hot, which may cause burns. 
  • Wear lightweight, breathable, moisture-wicking clothing: Light clothes reflect heat, thus keeping you cooler. 
  • Avoid strenuous activities: Engaging in intense physical activity in the heat makes the body release fluids more quickly, potentially leading to heat stress when sweat doesn’t evaporate quickly enough to cool the body.
  • Stay hydrated: Hydrating with water helps keep your body at a normal temperature.
  • Wear sunscreen: Protect your skin from the sun’s ultraviolet A and B rays by using sunscreen.
  • Switch to LED light bulbs: Incandescent lighting is less energy-efficient and produces more heat than LED lighting.
