The Circadian Code: Why Your Code Quality Depends on Your Light Exposure

As developers, we often treat our bodies like hardware that just needs caffeine to keep running. We pull late-night sessions, work in dimly lit rooms, and stare at blue-light-emitting screens for 12 hours a day. We optimize our CI/CD pipelines, our database queries, and our bundle sizes, but we often ignore the most critical piece of infrastructure in our stack: our own biology. Our brains aren’t just processors; they are biological organs governed by a 24-hour internal clock known as the circadian rhythm. This rhythm dictates everything from our core body temperature to our hormone production and, most importantly for us, our cognitive performance. ...

Probiotics, live beneficial bacteria and yeasts, offer significant health benefits across various stages of life. From infancy to old age, probiotics can support digestive health, boost the immune system, promote mental well-being, and even help with skin health. But how does their role evolve as we age, and which probiotics should be taken at different life stages? Infants (0-2 Years) Probiotics for Infants Infants, especially those born via cesarean section, can benefit greatly from probiotics. During a natural birth, babies are exposed to beneficial bacteria such as Lactobacillus and Bifidobacterium from the mother’s birth canal, which plays a crucial role in establishing a healthy gut microbiome. Babies born via C-section may miss out on this initial exposure, leading to a less diverse gut microbiome. ...

How Probiotics Help with Allergies

Author: Omid Farhang Published: September 10, 2024 Reading Time: 5 min

Allergies occur when the immune system overreacts to a typically harmless substance, such as pollen, dust, or certain foods. Probiotics, especially certain strains, can help regulate immune responses and alleviate allergic symptoms by influencing the balance of gut bacteria and modulating inflammation. Read before: Unlocking the World of Prebiotics, Probiotics, and Postbiotics: The Complete Guide 1. Regulating the Immune System Probiotics play a significant role in modulating the immune system, which is critical in managing allergies. In allergies, the immune system tends to skew towards a Th2-dominant response, leading to an overproduction of antibodies like IgE, which trigger allergic reactions. Probiotics, especially strains like Lactobacillus rhamnosus and Bifidobacterium longum, can shift the immune response towards a Th1-dominant response, which reduces the production of IgE and thus alleviates allergic symptoms. ...

Eating foods with saturated fat does not clog the arteries

Author: Omid Farhang Published: November 4, 2022 Reading Time: 1 min

I’ve been reading an article from medicalnewstoday.com and I found this part interesting: A team of cardiologists wrote an article stating that eating foods with saturated fat does not clog the arteries, as people once believed. They contend that the “fat free” movement caused higher intakes of carbohydrate foods, including sugars. This might explain why rates of heart disease have increased. Here is the link to the article mentioned above from BMJ Journal: Saturated fat does not clog the arteries: coronary heart disease is a chronic inflammatory condition, the risk of which can be effectively reduced from healthy lifestyle interventions
