Expected National Heat Awareness Day Deals

As National Heat Awareness Day focuses on public safety rather than commercial deals, expect to find valuable resources and educational campaigns rather than sales.

Look for public health departments and local non-profits to host free workshops or distribute cooling supplies. Brands like Gatorade and Hydro Flask may partner with awareness campaigns to promote proper hydration, while outdoor gear companies such as Columbia Sportswear or REI might highlight sun-protective clothing. Emergency preparedness suppliers like Ready.gov will offer guides on creating heat safety plans. We will update this page with confirmed live resources as May approaches.

History of National Heat Awareness Day

National Heat Awareness Day was founded by the Occupational Safety and Health Administration and the National Weather Service, an agency of the U.S. Federal Government. While there is no record of its first observance, the importance of this day and what it stands for is why we are including it.

The reality is that every year, in the U.S. alone, people suffer and die from heat-induced illnesses, which could easily have been prevented with the right protective measures and intervention. Groups that are especially vulnerable to heat are outdoor workers (like farmers and manual laborers), young children, elderly adults, people with chronic medical conditions, and pregnant women. Heatwaves have been on the rise over the past few decades, with a definite correlation to climate change and the crisis of global warming. In the U.S. itself, recent history shows the shocking death toll due to heatwaves. While various measures are being taken to adapt to rising temperatures and humidity, there is a need for awareness to be spread in order to mitigate the losses.

Therefore, this day was created in order to spread awareness to overcome the high-temperature-related issues. This day is also observed to encourage the consumption of water to avoid heat-related illness. Americans seem to still underestimate the health risks related to conditions of extreme heat or temperatures, even though it’s the deadliest weather condition in the country. With factors like pollution causing temperatures to rise earlier each year, the onslaught of the heat of summer is coming faster every year. For this reason, it is imperative that the nation at large begins to sit up and take notice of the fact that there are many groups in need of protection from an unexpected killer.

    The manifold benefits of drinking enough water and fluids cannot be stressed enough.

  2. Keep your fashion light and breezy

    Wear loose-fitting and lightweight clothing, made with breathable fabrics like cotton.

    Avoid stepping out into the sun during its peak hours, especially without protection.

  5. Limit your activity

    Leave the intense workouts for early mornings or nights, and take it easy during the midday heat.

Why National Heat Awareness Day Is Important

  1. Lobbies to protect the vulnerable

    Several years ago, OSHA began a Heat Illness Prevention Campaign to spread awareness about the dangers of working in conditions of extreme heat. Their petition for change could be boiled down to three simple demands for workers — shade, rest, and water. The onus falls on employers to ensure that their workers are receiving these basic requirements and are being protected from extreme heat and other hazardous conditions.

  2. It educates us on prevention methods

    By reinforcing such basic preventative measures, National Heat Awareness Day brings the reality of things we take for granted (like water) to the forefront and makes us more mindful of our own health.

  3. It resonates with people everywhere

    Heatwaves and heat-related health issues are on the rise all over the world, thanks to climate change. Therefore the message of National Heat Awareness Day is relevant to people across the globe, especially as many nations do not even have access to resources like drinking water and electricity. It opens one’s eyes to the larger realities of social injustice and climate change.
