With most of the United States experiencing high temperatures the past few weeks, it is clear that summer is here. As you may know, June 21, 2022 marked the summer solstice—the official start of summer. This day provided the longest amount of daylight for those in the Northern Hemisphere.
Mattingly and colleagues (2021) reported an association between increased amounts of daylight and reductions in sleep time. These same investigators also noted shifts in bedtime and wake time to later times as temperatures increased.
Speaking of sleep, the National Center for Health Statistics recently released a report related to sleep difficulties in adults using data from the National Health Interview Survey completed in 2020. A person was considered to have sleep difficulties if they reported “trouble” falling asleep or staying asleep “most days” or “every day” during the 30 days prior to the interview.
Using this data, Adjaye-Gbewonyo and colleagues (2022) estimated that 14.5 percent of adults in the United States had difficulties falling asleep in 2020, while a slightly larger percentage (17.8 percent) had difficulties staying asleep. These authors also reported their findings regarding sleep difficulties as it pertains to age, gender, race/ethnicity, education, income, and place of residence.

“Huh?” is used in at least 31 languages around the world! A version of the word can be found in nearly every language on Earth (Dingemanse et al, 2013). This research concluded that all languages studied included a word similar, in both sound and function, to the English “huh?” Regardless of language, the word is…
If you have a dog or cat, you’ve probably seen their ears moving toward an interesting or startling sound. For professional equestrians, watching the ears of their horse allows them to gauge their shifting attention. Humans still have these same muscles, and even more interesting is their relationship to our brain and how we pay attention. …
Tai Chi is not just for increasing balance; it may also help improve cognitive performance. In a recent randomized controlled trial, study participants who practiced a form of Tai Chi twice a week for six months improved their scores on the Montreal Cognitive Assessment (MoCA) when compared to a control group (Fuzhong et al, 2023)….
