Wash your hands

Slide 43 of 51: Among the lessons we've learned from the COVID-19 pandemic is the importance of washing our hands. Handwashing with soap removes germs and helps prevent infections. Infections can be transmitted by people touching an infected surface and then touching their eyes, nose, and mouth without realizing they are doing so. Germs from unwashed hands can get into food and drinks from those who handle and prepare them. Germs can be found on commonly touched items -- handrails, table tops, or toys to name a few -- and can be transmitted to another person by a handshake. Handwashing helps prevent diarrhea and respiratory, skin, and eye infections. ALSO READ: Foods and Drinks You Only Think Are Healthy

That’s why nostalgia has been shown to offset loneliness, boredom, and anxiety.
