Postural orthostatic tachycardia syndrome (POTS) is a condition where a person's heart rate elevates rapidly when going from seated to standing. POTS occurs because blood vessels don't tighten rapidly enough when you stand quickly. It's a form of autonomic dysfunction that causes blood to pool in the legs and the brain receives inadequate blood flow. … Continue reading Postural orthostatic tachycardia syndrome bites the dust!
Improper exposure to blue light is becoming more of a concern as artificial sources of light become more common. LED lighting is growing in popularity as it creates greater lighting at a much lower energy cost. We perceive this as light that is more blue. Exposing yourself to light at improper times of day disrupts … Continue reading Does blue Light disrupt the skin circadian clock
PCOS, or polycystic ovarian syndrome, is the most common hormonal disorder in women of reproductive age. Symptoms of PCOS include: Irregular menstrual cyclesHigh androgen(Male sex hormone) levelsThe development of cysts that rupture and cause pain Aside from the painful cyst ruptures, PCOS also negatively affects a woman's fertility. It's more common in women who are … Continue reading PCOS: The first step to treat it without drugs
Despite evidence of gut health benefits of Sun exposure, we're told to avoid Sun exposure. Ultraviolet rays from the Sun are a carcinogen they say, so it's best to stay away as much as possible. But there's more to it than that. We've known for years that less Sun exposure on the skin increases IBD … Continue reading Gut health benefits of Sun exposure
Menopause symptoms can be terrible whether you're pre-, peri-, postmenopausal. I need to do a lot more blogs on health factors that affect women beyond child-bearing age. Not only is it a tremendously under-served group, but it also happens to be one that regularly reads my blog. Fortunately, I dug in to the topic a … Continue reading Menopause symptoms are worse with circadian disruption
There was a fantastic review of circadian rhythms in autism spectrum disorder early last month. In it, they put forth the model that people with autism frequently have disturbances in sleep and circadian rhythms. Some of this is due to genetics. But along with the genetics component comes the environmental component, as well as the … Continue reading Autism and circadian disruption: Adding fuel to the fire?
We all know the drill: Many of us wake up bright and early in the morning Monday through Friday to get out and "make the donuts". Then, on the weekends, we stay up late and sleep in for an hour or 2 to catch up. We know sleep is important, right? It seemingly makes sense … Continue reading Sleeping in on the weekend may ruin your metabolic health
A study published earlier this month showed that variability in sleep timing and sleep schedule doubles a person's risk for metabolic dysfunction by increasing the risk of multiple metabolic abnormalities. These metabolic abnormalities include: High Body Mass Index(BMI) High Waist Circumference Elevated Systolic Blood Pressure Elevated Diastolic Blood Pressure Elevated Triglycerides Low HDL Cholesterol Elevated … Continue reading Variability in your sleep pattern doubles your risk of metabolic dysfunction
The Epstein-Barr virus, the virus that causes mono, is extremely common with a prevalence of 90% in humans. As with any virus, once you get it you always have it. Despite this, the virus normally "enters latency" and doesn't continue to cause any problems unless it becomes reactivated later in life. When it does get … Continue reading Can optimizing circadian rhythms protect against Epstein-Barr virus reactivation?
A study published yesterday showed that early time-restricted feeding(eTRF) for 4 days led to several metabolic improvements in overweight adults who were metabolically healthy. The study found that compared to eating from 8am-8pm, when doing subjects doing eTRF(8am-2pm) had: Decreased mean 24 hour blood glucose levels Decreased glucose spikes, especially at night(Duh) Increased ketones and … Continue reading Early time-restricted eating improves glycemic control, cortisol rhythm, and may promote autophagy
