…hug your loved ones more often! Psychology professor Dr. Thomas Joiner from Florida State University says, in studies, people who do the most hugging are less likely to get sick when exposed to a flu virus. It works because regular physical contact with other humans bolsters the immune system – by challenging it through exposure to other people’s microbes, which makes it stronger. Another reason hugs are a flu fighter? They reduce stress, which makes us more resistant to infections. So get hugging!
