Hi and welcome to this week’s look at natural health headlines on iHealthTube.com
Plenty of good news this week centered around aging and cognition…
Eating your greens has long been known to be good for you, now they may have another health benefit… keeping your brain healthy. Lutein is a nutrient found in leafy greens as well as things like avocados and eggs… recently it’s been connected with cognition… in a study that included 60 adults aged 25 to 45… those that had higher levels of lutein had neural responses equal to younger individuals rather than their peers.
It appears lutein plays a protective role… but it’s also a nutrient the body cannot make on it’s own and must be acquired through diet.
In addition to nutrients in your diet… physical exercise is showing to be beneficial in helping prevent cognition decline and dementia in old age.
A study out of Germany used 60 participants between 65 and 85 years old. The participants were tested before and after a 12 week period that saw them go through individually tailored exercise programs on a exercise bike.
The results indicated the physical activity influenced brain metabolism and helped protect cells, in addition to improving physical fitness.
How many of us gone to bed and watched TV or put our phone or tablet in front of our face? It’s pretty common… but new research is indicating that habit may be contributing to poor quality sleep.
A study out of the University of Houston had participants wear wavelength blocking glasses that eliminate blue light… three hours before bedtime for two weeks while still performing their regular nighttime digital routine. The results showed about a 58 percent increase in nighttime melatonin levels… that’s the chemical that signals your body that it’s time to sleep.
Most of these devices emit blue light… which can boost alertness and regulates our internal body clock. Experts continue to recommend limiting screen time before bed or applying filters or glasses that block blue light.
