Apparently, the ordinary thought of having a flu shot can make anyone feel bad somewhat, but a new study suggests the need to check your mood to have a more positive effect of flu vaccination.

Scientists from the University of Nottingham analyzed how different factors including diet, physical activity, mood, and sleep affect the efficacy of flu shots. The vaccination appears to work less in aged persons; the research team involved 138 participants between the ages of 65 and 85. Participants were meant to undergo behavioral evaluation for two weeks before the vaccination and four weeks after. The researchers recorded the level of flu antibody present in each participant’s blood after four weeks and 16 weeks post-treatment.

Your mood can help you fight germs

Exercise, healthy diet and sleep appeared to salvage many health conditions, but the mood was associated with the effectiveness of vaccination. This new finding can help combat germs this period because there’s no proven way to prevent the contraction of this flu completely.

The lead author of the research, Kavita Vedhara, Ph.D., health psychologists, wrote to Newsweek through email saying that some factors that alter the effectiveness of vaccination can be hardly altered, but the mood is one factor we can change. Vedhara added that it’s an observational finding, and its necessary to bear in mind that it lacks the cause-and-effect linkage, and the research team hopes to carry out a test where they can control mood and check vaccination effectiveness.

While there’s the need for more study, you can boost your mood before stepping out to get a flu shot. You can control the fear for needles, as it’s not unique to children. The chief psychologist at Montefiore Medical Center, Dr. Simon Rego points out that estimates are vast but may be up to 40 percent. Rego believes reducing the fear for needed causes improved mood.

Rego advises honing your energy towards a more positive stuff when you tend to nurture unpleasant thoughts such as considering why you need the flu shot. He suggests picking up your favorite book, and playing music could help you divert your attention.

Rego added that the brain subconsciously sends this feeling of having a needle pierce your body as a wrong thing, so it’s not bad to craft a pre-shot strategy that helps you.
