Effect of Vitamin D Supplementation, Omega-3 Fatty Acid Supplementation, or a Strength-Training Exercise Program on Clinical Outcomes in Older Adults: The DO-HEALTH Randomized Clinical Trial | Complementary and Alternative Medicine | JAMA | JAMA Network

In this randomized trial that included 2157 adults aged 70 years or older, 3-year treatment with vitamin D3 (2000 IU/d), with omega-3 fatty acids (1 g/d), or with a strength-training exercise program did not result in statistically significant differences in improvement in systolic or diastolic blood pressure, nonvertebral fractures, physical performance, infection rate, or cognition.

Effect of yoga as add-on therapy in migraine

Objective To evaluate the effectiveness of yoga as an adjuvant to conventional medical management on clinical outcomes in patients with migraine.

CONTAIN was a prospective, randomized, open-label superiority trial with blinded endpoint assessment carried out at a single tertiary care academic hospital in New Delhi, India. Patients enrolled were aged 18–50 years with a diagnosis of episodic migraine and were randomized into medical and yoga groups (1:1). Randomization was computer-generated with a variable block size and concealed. A predesigned yoga intervention was given for 3 months. Outcomes were recorded by a blinded assessor. The primary endpoint was a decrease in headache frequency, headache intensity, and Headache Impact Test (HIT)–6 score. Secondary outcomes included change in Migraine Disability Assessment (MIDAS) score, pill count, and proportion of headache free patients.

There Is No Such Thing as Conscious Thought – Scientific American

… we believe subjectively that we are possessed of far greater certainty about our attitudes than we actually have.

… consciousness is not what we generally think it is. It is not direct awareness of our inner world of thoughts and judgments but a highly inferential process that only gives us the impression of immediacy.

Philosopher Peter Carruthers insists that conscious thought, judgment and volition are illusions. They arise from processes of which we are forever unaware

Orangetheory Fitness CEO Peddles Inaccurate Information to Lure Members Back to the Gym

On the last Friday in August, Dave Long, the CEO of Orangetheory Fitness (OTF), emailed a “pep talk” to members of the fitness studio. In a 500-word screed, Long announced that more OTF studios would be reopening as an increasing number of states begin to lift restrictions on public gatherings and return to a semblance of normalcy. The tone of the email was exciting and reassuring, littered with exclamation points and virtual high fives. But about three paragraphs in, Long presented his thesis behind the reopenings, writing “There’s no evidence to support the fact that gyms are contributing to the community spread of COVID-19 above any other types of businesses.” Long claimed that gyms like Orangetheory were vital because they lessen the impact of the virus and could even prevent it by keeping members in good health, a claim he attributed to “doctors” and the International Health Racquet & Sportsclub Association (IHRSA).
