For people in some parts of the world, hearing a forecast with an excessive heat warning is a common event. However, others are less accustomed to such extreme temperatures. Because climate change has led to unusual weather conditions, even those who live in areas that typically experience moderate temperatures may find that they face much higher temperatures more often.
In any case, it’s always wise for people to know what to do to keep themselves comfortable and safe during high temperatures. Which tips should they try, and why are they useful?
Although people may hear a weather forecaster casually refer to an excessive heat warning to put predicted temperatures into context, that is not an official phrase used by the National Weather Service in the United States. However, that organization does have several ways to categorize extreme heat. Knowing about them can help people decide when to act and how.
A heat advisory is the least-severe level, issued when weather forecasters expect high temperatures that are not warm enough to reach warning criteria. There’s also an extreme heat watch, which indicates there are favorable conditions for extreme heat events, but uncertainty still exists regarding if it will occur and when. Finally, forecasters issue an extreme heat warning when they expect extremely dangerous heat or if it is currently happening.
One caveat, though, is that weather authorities do not universally apply these alerts. They do so while assessing a local area’s preparedness for the expected temperatures. If a city or state has excellent infrastructure to equip it for hot weather, those locations will generally fare better than those that rarely get extreme temperatures.
An excessive heat warning gives people a good excuse to stay indoors as much as possible, and preferably in air-conditioned rooms. Although many homes have air conditioning, some don’t.
Fortunately, there are often strategies in place to accommodate that reality. For example, the United States has numbers people can call to find the nearest cooling centers. These are air-conditioned facilities where individuals can go for hours at a time if needed.
Sometimes, local news broadcasts will announce the openings of new cooling centers. This is especially true because many of these locations double as other places, such as libraries. Paying attention to those updates is a practical way to stay prepared in case it becomes necessary to attend those places or inform others about them.
Staying hydrated as one of the easiest and most important things people can do during an excessive heat warning. However, they should get into the habit of drinking before they feel thirsty. If they wait until then, they may already be mildly dehydrated, which is something better to avoid.
Some people find it difficult to drink enough throughout the day, regardless of the outdoor temperatures. In those cases, trying flavoured water or adding an electrolyte packet that includes flavoring to tap water are too easily accessible options that can make plain water more palatable. Buying a reusable water bottle is a sustainable option that can save money over the long term.
Some also have exterior markers to help people gauge how much they drink throughout the day and make adjustments if it is not regular enough. Those can become excellent visual reminders to drink more or reinforce that people are already doing well in keeping themselves hydrated.
It is not always possible for people to go indoors for relief from the heat during the hottest part of the day. For example, some have outdoor jobs. But when it is an option, people will be most comfortable if they can stay indoors during the heat of the day by planning their activities accordingly.
A common misconception is that it will be hottest at noon. Actually, the heat will likely be most intense a few hours after that, before gradually cooling. Some managers that oversee workers in industries such as construction may proactively deal with an excessive heat warning by changing the planned schedule for a particular day.
The most effective strategy is usually to have the most strenuous tasks occur when the warmth is least intense. That may mean that shifts start earlier and earlier, allowing workers to be inside during the worst of the heat. When that is not feasible, those overseeing outdoor projects may respond in other ways, such as by having employees take breaks more frequently and teaching them the signs that they are becoming overheated.
Heat-related illnesses can have severe consequences and become life-threatening. Unfortunately though, people experiencing them are not always able to recognize the symptoms within themselves. That is particularly likely if their condition has deteriorated rapidly during an excessive heat warning or otherwise.
Heatstroke is the most serious heat-related illness, and confusion and an altered mental state are two of its possible symptoms. That helps explain why people cannot always recognize signs of a problem in themselves before it’s too late.
That’s a good reminder to check on older people in the area or others who may be especially vulnerable during high temperatures. For example, people with some disabilities have difficulties regulating their body temperatures, and individuals may take medications with side effects that include a reduced heat tolerance.
Become familiar with the top symptoms of heat-related illnesses. Then, whether you recognize them in yourself or in others, don’t wait too long to get medical attention. Keeping a person in this state cool and hydrated may be good first steps, but often it is necessary for more intensive medical interventions.
Here are some things people often wonder when learning about excessive heat warnings.
This is not a phrase used by the National Weather Service in the United States, but some newscasters and others discussing the weather may use it casually. Learning about the official terminology and meanings can increase overall preparedness and understanding.
Because thirst may indicate someone is already slightly dehydrated. It’s better to stay hydrated by drinking water throughout the day rather than waiting until someone feels they need it.
It’ll probably be even warmer up to a few hours after noon. Planning the day’s activities accordingly will help people stay comfortable during high temperatures.
With many parts of the world experiencing extreme heat more than usual, this upward trend could cause some people to become complacent. This may mean that they don’t think it’s necessary to prepare or react after hearing news of an expected excessive heat warning. Such attitudes could become dangerous, especially because individuals who have become adversely affected by the temperature and maybe suffering heat-related illnesses cannot always recognize the issue in themselves.
Following the suggestions here and others that make sense for the local area and its infrastructure are some of the most effective ways to stay safe and uncomfortably warm temperatures. Besides making sure those in their household remain safe and comfortable, becoming more observant of others during these challenging circumstances is also wise.
