For the study, researchers looked at 7,054 people who were diagnosed with headache in a Boston emergency department over seven years. Scientists then compared temperature levels, barometric pressure, humidity and other air pollutant or weather factors during one to three days leading up to the hospital visit.
The study found that higher temperatures increased the risk of headache. The risk went up by 7.5 percent for every five degree Celsius increase in temperature. Lower barometric air pressure within the two or three days leading up to a person's hospital visit also increased the risk of non-migraine headaches. Air pollution levels had no affect on the risk of headache in the study.
"Air temperature and pressure have been widely cited as a possible trigger for headaches, particularly migraines, but the potential connection hasn't been well-documented," says study author Kenneth Mukamal, MD, with Beth Israel Deaconess Medical Center and Harvard Medical School in Boston.
"There is growing interest in exploring whether there is any link between air pollution and headaches. While our study did not find an association, other studies have shown that air pollution has possible links to other health problems like heart disease and stroke," said Mukamal.
It is estimated that costs associated with migraines total 17 billion dollars in the United States.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
