The National Weather Service explains the importance of wearing a protective clothing and sunscreen during the heat of the day to protect your skin from sunburn

“Summer has taken its time arriving in the Northeast, but it’s coming in HOT,” the NWS wrote in a post on X. “Triple-digit heat indices will be common through next week, with oppressive humidity.”

Look at the wind flow, time of day and cloud coverage as important factors in your decision to be outside. If the air temperature is lower and the wind speed is not strong, you are at risk for heat-related illnesses. A very humid 88-degree day with no wind could be riskier than a 95-degree day with low humidity.

Heat exhaustion is your body’s warning sign that you’re starting to overheat, Salas says. Generally, symptoms include sweating more than usual, weakness, dizziness, fainting, pale skin, nausea, vomiting and fatigue.

Before starting your lifeguard shift or going to that barbecue, take a moment to check the heat index. It includes the air temperature as well as the humidity to give you a sense of how hot it is outside.

If you can, do outdoor activities in the morning before the heat of the day sets in. The afternoon is one of the most dangerous times of the day.

It is possible to go for a walk or go to the pool. Cotton and linen fabrics have big pores on their woven threads, which allow for air circulation, or material that draws perspiration away from your skin, which helps it to evaporate more quickly.

Salas says to choose loose-fitting silhouettes. The sweat on your skin can’t evaporate if you wear clothes that are too tight. “I’m sure people don’t love sweating profusely, but sweating is actually our friend when it comes to heat.”

A wide-brimmed hat and sunscreens are important to prevent sunburn, according to a professor at the University of Central Oklahoma.

How hot can you feel on a hot day? Prevention of heat exhaustion in the outdoors and in the park and the woods, and public libraries

Your location can make a big difference in how hot it feels. The heat is absorbed by dark surfaces like asphalt. shaded areas can feel cooler due to less solar exposure. “You can reduce the temperature around you 10 degrees or more by just moving to an area that’s shaded.”

So if you’re a dog walker, it’s a good idea to walk your dogs in the park or woods on a hot day. Or if you’re headed to the pool, bring a sun umbrella or a pop-up tent to provide some coverage, Provencio says.

If you or someone you know is experiencing signs of heat exhaustion, Salas recommends going into an air-conditioned room. Provencio recommends public libraries because they’re free and open to everyone.

Don’t drink on hot days, she says. You may be tempted to crack open a cold beer on the beach, but it’s a diuretic that can dehydrate you and impact your ability to sweat and cool yourself.

If you’re feeling unwell, put a wet towel, ice pack, or cooling towel under your arms and groin and it will keep you from getting hot from the sun.

Salas says that some of the body’s major blood vessels live there. “Cold can help cool the blood running through them.”

Welcome to summer: U.S. braces for first significant heat wave of the new season, according to the Washington Post-Newtonian

“It’s certainly going to feel like middle-of-summer humidity,” he said. “I mean, we’re talking low-to-mid 70-degree dew points, and that’s going to feel pretty uncomfortable.”

In Wisconsin, the heat index could peak between 100 and 105. NWS Meteorologist Ben Miller told Wisconsin Public Radio that since “it’s been a pretty mild spring,” people aren’t acclimated the same way they are later in the summer.

The city of Philadelphia has instituted a code red warning for its residents in order to transfer homeless people indoors, member station WHYY reports. The heat index is expected to be above 95 degrees for three or more days in a row, which puts the notice into effect.

Heat waves are lasting longer and peaking at higher temperatures than in the past due to climate change. The average number of heat waves the U.S. experiences today has doubled since the 1980s, and the length of the dangerous heat wave season has increased from about 40 days to roughly 70.

In the summer of 2024, the world’s temperatures were the hottest on record. Last year unseated 2023, the previous record holder for dangerously high temperatures.

Climate change can affect human health in an immediate way, but can also threaten the planet’s plant and animal life.

The members of the United Nations agreed to try to reduce greenhouse gas emissions in order to counteract the effects of climate change at a conference in Paris in 2015.

The Heat Index: Some Prescriptions for Avoiding ills in the Northwest Slope Sedimentation Region (Secure Report)

The heat index is a measure of how hot it actually feels — based on the temperature and the humidity — compared to the actual number on the thermometer.

The NWS encourages people to never leave anyone alone in a closed car, use air conditioners and the shade when possible, and drink plenty of water, even if not thirsty, as some measures to avoid falling ill as a result of the heat.
