For those whose team wins the trophy, several side effects could make the day even better, including the taste of your food and your perception of yourself.
The more you care about a team, the more you can feel these effects.
He and his colleagues discovered that people enjoyed the flavors more on the days the team won. "When we looked at how they reacted to these different flavors, in the games they had won, the flavors had a sweeter and less acidic taste, as opposed to their loss," said Dando.
One of their theories to explain this result is that, when you are happy, your system contains more serotonin, a "neurotransmitter very strongly related to mood and affect". Having more of that running in your body because you had a good day could influence how things look, because there are serotonin receptors in our taste buds, said Dando.
This does not necessarily take into account the taste changes seen in their research, but according to Dando, there may be another explanation of how much people liked ice cream on the days their team won.
"There is another interpretation, probably more simplistic," he said. "If you're really in a good mood, it takes less to satisfy you, and so something might taste a bit better because your base level is a bit higher."
You feel smarter and more attractive
"Research shows that when a team succeeds, people feel that their cognitive skills are better.They believe that their social skills are better.When a successful team, she has a more positive view of life in general, "said Wann.
"When the team won, she had a more positive view of her cognitive skills and social skills," said Wann.
"All that is affected by a positive mood increase will be increased by watching your team win," he said. "Research clearly shows that it will improve your mood, your happiness and all that goes in that direction will increase."
You could end up spending more
This may not be a good side effect for you, but those who work in bars and restaurants around great games might appreciate it.
"I have often thought that they should do a study on tips," said Wann. "I think after the team's win, the tips would be higher because happy people are giving more tips."
In addition, he added, people celebrating a win are more likely to go out to eat or buy team memorabilia.
A victory could even have an effect on the economy of a whole country.
You might feel like you have acquired a status
With his colleagues and his mentor, he found that those who saw the winning team win – a university basketball game in front or a 1994 World Cup championship game at a night of surveillance – had levels of higher testosterone.
Testosterone is associated with dominance and social behavioral behaviors in men, Bernhardt said; his study was only about men.
"Sometimes domination is aggressive but not usually," he said. "Most often, it's noisy, impulsive behavior or other manifestations that give the impression of a gain of status."
It's a way to escape
Although football – or any other sport – can have these effects on viewers, whether their team wins or loses, it can also be a form of escape for those who need it.
However, he warned that people should not let a sport have so much effect on them.
"Although I'm looking for the Super Bowl Patriots, it will not end my days," he said. "This is not a chemotherapy or radiation therapy, so really, it will have no effect on our life … If we only talk about your usual and daily effect on my life: none!"
