Tips For Staying Healthy This Summer

There’s been a “mega heatwave” in the western areas of the United States (e.g. Arizona, California, Utah, Wyoming) recently. This has caused planes to be grounded, people to stay indoors, and a rise in health-related illnesses such as dehydration. Unfortunately, the older you get the less you realize how hot it is because your body isn’t as hydrated so it doesn’t sweat as much. Nevertheless, people over 65 make up 36% of heat-related deaths because heat is more of a threat to them. This is because many of them have health conditions (e.g. heart disease, high blood pressure, diabetes) that make them more susceptible to heat-related illnesses. Many of the medications that are used to stay healthy also make it more difficult for people to cool off. Since this heatwave isn’t even coming in the middle of the summer, some Read More +

Cicada’s Sounds Are Problematic For People With Hearing Loss

Cicadas are a type of insect that spends the majority of its lifetime underground. They make their return every 15 years and this year the cicadas have returned. This is because they’re ready to mate before they die. For this reason, they make a loud clicking sound that’s used to attract their mate and repel birds. Cicadas are noisy insects but they’re also beneficial insects as well. This is because they help prune mature trees, aerate the soil, and once they die, their bodies act as an important source of nitrogen that trees need in order to help them grow. However, even though these insects are mostly harmless, they’re still annoying nevertheless. This is because their high-pitched buzzing sound is so loud. In fact, it can be loud enough to drown out the sound of a jet plane flying overhead. Read More +

How Auditory Perception Is Improved By White Noise

There are different types of noise. For instance, when you have a continuous background of white noise you’ll be able to hear pure sounds better. This is something that researchers from the University of Basel have recently discovered. They’ve included a summary of their findings on their website and in Cell Reports. Although we know that hearing is an important part of communicating, we don’t have a good understanding of how acoustic signals are perceived or processed so that we can make sense of them. What is clear is that the more precisely we’re able to distinguish sound patterns the better we’re able to hear. This is especially true in noisy backgrounds. Understanding the “Auditory Brain” The University of Basel’s Department of Biomedicine Professor Dr. Tania Rinaldi Barkat led this investigation into the neuronal foundation of sound perception and discrimination Read More +
