Yogurt Positively Effecting Mood Actually

Yogurt Positively Effecting Mood Actually the statement about yogurt positively effecting mood (Orenstein & Swencionis, 1990) was found, upon closer review, to be based upon less solid evidence. Originally extracted from a Daily Mail news article that derived it an article found on NHS Choices that deals with health, the NHS, in turn, had found their source from a study detailing research of yogurt on mice.

Researchers in both Canada and Ireland (Bravo et al., 2011) used 36 adult male mice divided into a study and control group where mice in the control group were fed a broth without bacteria whilst mice in the experimental groups were fed the broth containing L. rhamnosus, a bacteria inherent in yogurt. The experiment was carried out for 28 days for one hour every morning.

At the end of the study, the researchers measured the corticosterone stress levels in the mice and evaluated their behavior under various conditions, for instance behavior of the mice contrasted in a maze, in water or in open space was assessed. In case these conditions would still carry confounding effects, researchers furthermore evaluated possibility of the vagus nerve leading to possible effect of the bacteria.

They therefore severed the vagus nerve in the mice and concluded that if the mice no longer appeared stressed when served the bacteria-filled yogurt, then yogurt may actually prove conducive for reducing stress. Finally, the researchers examined the actual brain tissue of the mice in order to investigate levels of GABA receptor functioning. Results were that mice fed with L. rhamnosus behaved in less stressful ways compared to mice who were fed the placebo.

In both instances of being submerged in water and wandering in the maze, treated mice acted less anxious than the control group. Levels of stress-related corticosterone were also found to be significantly lower in the treated mice as were levels of GABA receptor expression in certain parts of the brain, and, finally, the behavioral and neurochemical effects also differed in mice who were fed the broth and had their vagus nerve removed. Bravo et al.

(2011) concluded that their findings demonstrated the importance of the role that bacteria plays in communications between gut and brain and suggested that probiotic bacteria may be helpful for reducing anxiety, stress, and depression. Their findings are, however, inconclusive and should be treated with caution particularly since the study was essentially conducted on mice under laboratory conditions and, therefore, whilst interesting does not show that probiotic bacteria in yogurt can ease stress in humans.

The physiology of mice is different to humans and they may react differentially to the effects of the bacteria. Secondly, amount of bacteria fed to mice may differ form the amount of bacteria inherent in yogurt. Thirdly, despite efforts taken to screen confounding variables, neurochemical changes discovered in mice may have resulted from other conditions rather than that of the bacteria. In conclusions, we may say that whilst there its potential for future study, evidence of yogurt on reducing stress in humans still needs to be more closely investigated.

Jump-rope and Mood Jump rope being an exercise and exercise shown in dubiously to have positive impact on mood in that it strengthens heart and lungs, there is a huge amount of research correlating effects of jump rope, in particular, and exercise, in general, on humans. Exercise, and that includes jump rope, reduces stress by several mechanisms that include releasing neurochemicals that include neurotransmitters and endorphins that positively impact the mood.

Exercise also reduces immune system chemicals that exacerbate depression, and increase body temperature that can have a calming effect (Mayo Clinic: Depression and anxiety: Exercise eases symptoms). As regards impact of skipping rope on mood, an interesting recent study adds to the mass of significant results by investigating the effects of a forty-week rope-skipping program on the physical fitness of elementary school children. The participants were two classes of third grade elementary students in an elementary school in Pingtung, China (Lee, 2010).

20 children were randomly divided into an experimental and control group, with each group containing 10 male and female students. The experimental group jumped rope 5-8 minutes per day, five days a week for 42 weeks. Their body composition, cardiorespiratory endurance, and mood were measured (and the latter observed) at the end. It was found that not only was there a significant difference in all these variables, but also that the stamina and energy of the students in the experimental study were significantly higher than those in the control group.

Although other conditions may have impacted mood, a significant mass of research leads to conclusive evidence of the effects of exercise on mood. Rope jumping raises heartbeat that has a consequent positive effect on emotions. As reduction of stress levels, therefore, a curriculum or rope jumping is heartily recommended. Mountain / Outdoors and Mood "Climb the mountains and get their good tidings. Nature's peace will flow into you as sunshine flows into trees. The winds will blow their own freshness into you, and the storms their energy." (John Muir, 1901, p.

56) Poets and literary figures have extolled the outdoors for centuries as providing vitality and vigor as well as healthful effects on mood and researchers (e.g. (Plante, Cage, Clements, & Stover, 2006) have agreed. The Attention restoration theory (Kaplan & Kaplan, 1995) suggests that environmental regions such as mountains and rivers have this stimulating effect due to their novel and divers we offering of stimuli. Viewing images of natural vs.

built environments has often been found to elevate moods and being in an outdoor setting for even a short while diminishes stress, lowers fatigue and elevates mood. However effects of outdoor settings may be confounded by effects of social interaction and physical exercise that also raises mood. To that end, therefore, Ryan et al. (2010) excluded those variables in a set of five studies and found that the element of nature alone was sufficient to conduce an enhanced state of invigoration an elevated mood.

All five methodologically varied studies showed definite associations between the outdoor environment and subjective vitality and all of this was produced by natural elements in the setting alone. Whether or not focusing on negative emotions hinders decision-making skills and reduces happiness levels is a complex subject that largely depends on the context and intensity to which this introspection occurs as well as other details.

A thorough review (Blanchette & Richards, 2010) on this and on the influence of emotion in general on higher-level cognitive processes found that interpretation of instances and risk-taking were certainly influenced by.
