Summer nights in Syracuse are getting hotter, and that could make people sicker – syracuse.com

Syracuse, N.Y. For three straight nights this week, Syracuse set records for the hottest nighttime temperatures.

Its an extension of a long-term trend of increasingly hotter summer nights: Syracuses nighttime lows are about a degree warmer than they were a decade ago. And while high temperatures get headlines, hot temperatures overnight are of equal or greater concern for human health.

High nighttime temperatures are dangerous because if somebodys body temperature is elevated, it doesnt come down as much or as quickly, said Nicholas Rajkovich, an architecture professor at University of Buffalo who researches the effect of climate change on buildings and people. With people who dont have access to air conditioning or other kinds of cooling, over the course of a couple of days it can cause physiological problems like heat stroke or heart attacks.

Excess heat directly kills an average of 700 Americans each year, more than any other weather-related cause, according to the Centers for Disease Control and Prevention. The toll is likely greater than that: Studies indicate that hotter nighttime temperatures can increase the chances for stroke and heart attacks, and can cause poor sleep, which can lead to longer-term health problems.

Its getting hotter in the summer in Syracuse, especially at night, according to new normal temperatures calculated this year by the National Weather Service. While Syracuses average high temperature in summer is about a half-degree hotter than it used to be, summertime lows are nearly a full degree higher.

Its not just Syracuse: Unusually hot low temperatures have risen faster across the continental U.S. than high temperatures, according to the Environmental Protection Agency.

Nighttime heat is especially hard on people who have a hard time regulating their temperature, including the elderly and those with chronic conditions, including diseases of the heart, kidneys and lungs. In addition, the elderly and those with chronic conditions are more likely to take medicines that can cause dehydration or restrict sweating.

People with heart disease can be on medications that try to keep them dry to begin with, so theyre not as able to control their body temperature through sweating, said Dr. Kathryn Watson, an emergency medicine specialist at St. Josephs Health.

On Saturday, Sunday and Monday, Syracuse set or tied records for the hottest nighttime temperature recorded on those dates since records began in 1902. Monday nights lowest temperature was a stifling 78 degrees. The temperature Sunday night and Monday morning was worse, never falling below 81.

And those were outdoor temperatures; in stuffy houses and apartments that had soaked up the days heat and stored it into the night, it was even hotter.

The heat was bad enough, but on some nights this week humidity soared into the 90% range, making it difficult for sweat to leave the body and take heat with it.

Primarily the way we cool our bodies is through evaporation, and evaporation becomes extra inefficient when the humidity goes over 75%, said Dr. William Paolo, chair of emergency medicine at Upstate Medical University. Now you have extreme heat during the day without cooling down at night, plus humidity that wont allow for cooling. Thats a bad combination when an individual needs a reprieve from the heat.

The problem is worst in apartment buildings in Syracuse, said Sally Ward, director of energy and housing for PEACE, Inc., a local nonprofit.

Heat rises, and you get to the top floors of some of these apartment complexes and its brutally hot, Ward said. We have a concrete jungle effect here.

PEACE is one of 18 local contractors that installs the window air-conditioning units for low-income people who have medical conditions exacerbated by heat. Those include asthma, chronic obstructive pulmonary disease and autoimmune conditions, Ward said.

In Syracuses third-hottest June on record, its not surprising that more people are applying for the air-conditioning units this year.

Last year, we did a total of 84 from May until September, Ward said. Were already at 60, and we have all of July and August to go.

Other contractors in Onondaga and Oswego counties are likely just as busy, she said. To apply for the air-conditioning program, call 315-435-2700, ext. 1.

Air-conditioning can be a lifesaver, but we need to make other changes to keep people healthy as the climate warms, Rajkovich said. Some people cant afford to buy or run air conditioners, he said, and others are reluctant to install them for fear someone could break in the window.

Rajkovich says we need to look at other ways to keep houses cooler, such as adding insulation, installing energy-efficient windows, using reflective colors on roofing and siding, and improving air flow inside homes. State and local governments offer programs to help people afford those improvements, he said.

Running air-conditioners should be a last resort, he said, because they help burn the very fossil fuels that are heating up the climate in the first place.

Air-conditioning was invented in Syracuse, but Im hoping we can figure out something where we just dont add a lot of greenhouse gases to stay cool, Rajkovich said. Syracuse has always had hot summers, but its going to get even hotter in the future.
