🌙🌡️ New research from the Center shows that sleep, metabolism, and body temperature are tightly linked, and that environmental temperature and light exposure can significantly shape these relationships. Read more: pubmed.ncbi.nlm.nih.gov/42728207/ #SleepResearch #Metabolism #Thermoregulation

It’s very humbling to be a beginner at any stage in life, and learning the saxophone has proven to be very humbling for me. With more practice, I will get better, and perhaps my mouth will hurt less 😀 🎷

In contrast, changes in glucose homeostasis seem to occur independent of the advanced pulmonary antioxidant defense during the active phase.

The team found that exposure to concentrated PM2.5 during the inactive phase induces a more profound vascular, pulmonary, and systemic inflammatory and redox responses than exposure during the active phase, when antioxidant defenses are enhanced.

The study showed that while exercise training improved exercise capacity regardless of diet, male mice consuming a low-BCAA diet did not exhibit the same exercise-induced cardiac growth observed in mice fed a high-BCAA diet.
