People who sleep poorly are more likely than others to have a brain that appears older than it actually is. This is the result of a comprehensive study by the Karolinska Institute. Increased inflammatory activity in the body could partly explain this correlation. Poor sleep is associated with dementia, but it is unclear whether unhealthy […]
The Light in Your Bedroom Could be Harming Your Heart Without You Realizing It
A preliminary analysis to be presented at the American Heart Association’s 2025 Scientific Sessions found that more artificial light at night correlates with increased stress signals in the brain, inflamed blood vessels, and a higher risk of heart disease. The researchers described artificial light at night, often referred to as nocturnal light pollution, as nearly […]
Why a Regular Sleep Pattern is Particularly Important for People Recovering from Heart Failure
People recovering from heart failure should consider improving their sleep regularity, according to a study by Oregon Health & Science University. The research team found that even moderately irregular sleep doubles the risk of another clinical event within six months. The results were published in the journal JACC Advances. A clinical event can be another […]
The Circadian Clock in Heart Failure
Disruption of the circadian rhythm, which naturally changes on a 24-hour cycle, has been linked to heart disease, but it is unclear how this leads to the condition. A research team at Baylor College of Medicine and collaborating institutions investigated the function of the protein Rev-erbα/β, a key component of the circadian clock, in the […]
Severity of Heart Attack and Circadian Rhythm: What is the Connection?
The molecular mechanism responsible for the varying severity of heart attacks depending on the time of day has been uncovered by researchers at UTHealth Houston. This could pave the way for innovative treatments that adapt to the natural circadian rhythm. The results of the study were published in Nature. How the Time of Day Affects […]
