The Northern Hemisphere might be melting and explosive diarrhea is spreading across the US…
But in grim moments like these, it feels more important than ever to have a laugh and rediscover your sense of wonder.
Consider this your Science Survival Guide to the July 4 weekend.
Whether you’re coping with airport delays, hosting a barbeque, dealing with a firework-anxious pet, or trying to avoid an awkward family debate, we’ve got you covered.
Science-backed tips and tricks for July 4
It’s going to get hot this weekend in many places across North America, so it’s best to be prepared.
Make sure you have lots of water and sunscreen… oh, and make sure you apply your sunscreen correctly.
Most of us don’t.
Are you taking any medications? Some drugs can make you more susceptible to the heat, so be extra careful with them.
Even if you stay inside, keep in mind that the Sun can still burn you through a window.
If you’re out in the elements barbecuing, don’t wash the raw chicken first. It’s a common misconception that you need to, and you don’t want to make everyone sick.
If you’re drinking alcohol during the day, also keep in mind that it can make you more susceptible to the heat. Counting your drinks can help slow you down, scientists say.
At nighttime, when the fireworks start, stay a safe distance, no matter how pretty they are. Evidence suggests that loud noises can damage your hearing.
If you happen to have a pet that’s anxious about the fireworks, scientists also have a few tips to keep them calm.
Or maybe it’s you who is anxious. The social stress and family drama can be a lot.
