Covid-19 vaccine not linked to lower fertility rates
Concerns about the Covid-19 vaccine preventing pregnancy can be put to rest.

Fertility rates between vaccinated women and those unvaccinated are nearly identical. However, Covid infections in men have been linked to lower-quality sperm.
Multiple major natural disasters associated with lower mental health assessment scores
What doesn’t kill you makes you stronger, except maybe not for people who’ve experienced multiple major disasters. New research has found those involved in major events, like floods and hurricanes, score lower in mental health assessments than the national average. The study, published in the journal Natural Hazards, reveals the need for mental health programs in communities where major disasters frequently occur.
Common food additive negatively impacts gut bacteria
A common food additive could be making you sick. Researchers have found carboxymethyl cellulose, or CMC, negatively affects gut bacteria in healthy people. CMC was previously thought to be a safe additive to help improve a food’s texture and shelf-life. However, a paper published in the journal Gastroenterology discovers that CMC consumption, over time, could promote chronic inflammatory diseases.
Psychological well-being shown to slow cognitive decline
And finally… is happiness the key to life? A study published in the Journal of Aging and Health (University of Michigan) has found people with better psychological well-being are less likely to develop dementia and other cognitive impairments. The participants, all age 60 or older, spoke with researchers five times over the course of 12 years. Researchers discovered a better psychological well-being improves the participants’ quality of life.
