Being in a positive mood on the day of receiving flu jab can increase the protective effect of the vaccine, reveals a new study.
The study was published in the journal Brain, Behaviour and Immunity also revealed that flu vaccination was found to be useful only in 17 to 53 percent of older adults when compared with 70-90 percent of younger people.
Kavita Vedhara, Professor at the University of Nottingham in Britain, said, "Vaccinations have an incredibly effective way of reducing the likelihood of catching infectious diseases. But their Achilles heel is that their ability to protect against disease is affected by how well an individual's immune system works."
In this study, the research team studied the participant's negative mood and positive mood, diet, physical activity, and sleep. About 138 older people were investigated three times a week in six weeks.
The research team measured the amount of influenza antibody in the blood of the participants first at four weeks and then after 16 weeks of vaccination to know the effectiveness of the flu jab.
The findings of this study suggested that having positive mood over the six-week period found to play an essential role in how the flu jab worked.
A good mood was found to have a more profound association with higher levels of antibody,revealed the research team.
On the same day of vaccination, the research team found that the flu jab had an incredible effect on people accounting for between 8 and 14 percent of the variability in antibody levels.
Psychological and behavioral factors including stress, physical activity, and diet might have a profound association with the well-being of immunity.
Certain foods are known to transform the mood due to the presence of specific compounds. Many studies have shown that diet can affect the mood.
Foods like honey, cherries, fatty fish like mackerel and snapper, beetroot and chocolate can lift the mood of a person immediately.
