Amazon indigenous group’s lifestyle may hold a key to slowing down aging

Tsimane people are unique for their healthy brains that age more slowly  A team of international researchers has found that the Tsimane indigenous people of the Bolivian Amazon experience less brain atrophy than their American and European peers. The decrease in their brain volumes with age is 70% slower than in Western populations. Accelerated brain volume loss can be a sign of dementia. The study was published May 26, 2… read more


Sleep

Music listening near bedtime disruptive to sleep

Most people listen to music throughout their day and often near bedtime to wind down. But can that actually cause your sleep to suffer? When sleep researcher Michael Scullin, Ph.D., associate professor of psychology and neuroscience at Baylor University, realized he was waking in the middle of the night with a song stuck in his head, he saw an opportunity to study how music — and particularly stuck songs — might affect sleep patterns. Scullin’s recent study, published in *Psychological Science,* investigated the relationship between music listening and sleep, focus… read more

Defying body clock linked to depression and lower wellbeing


People whose sleep pattern goes against their natural body clock are more likely to have depression and lower levels of wellbeing, according to a large-scale new study. Research led by the University of Exeter, published in *Molecular Psychiatry*, also found the most robust evidence to date that being genetically programmed to be an early riser is protective against major depression, and improves wellbeing. Researchers suggest this may be because society is set up to be more aligned to early risers, through the standard 9-5 working pattern. COVID-19 has led to more flexible work… read more

Medicine and
Supplements

Ginger, cinnamon and turmeric have been used in food preparation for centuries and implicated as health-promoting due to their anti-inflammatory and antioxidant properties, but their effects on health and specific diseases such as diabetes and cardiovascular disease need more research. A new study from Clemson University examined how these spices as well as the curcumin and curcuminoid pigments found in turmeric affect cholesterol levels in people with type 2 diabetes. The researchers analyzed 28 studies of randomized controlled trials that included a total of 1049 control patien… read more
