According to the CDC, cheering or chanting during the Superbowl is not recommended, and that you should resort to stomping, clapping, or hand-held noisemakers instead.
The CDC also recommends that you limit alcohol consumption as consuming alcohol may make you less likely to follow COVID-19 safety measures.
The guidelines also recommend planning your bathroom and snack trips strategically by avoiding “using restroom facilities or concession areas at high traffic times, such as half-time or immediately at the end of the event.”
And if you plan on gathering outside to watch the game in cold weather, make sure you, wear your mask under your scarf, gaiter, ski mask, or balaclava. Keep a spare mask in case your mask becomes wet from the moisture in your breath or from snow or rain.
