Benett/Dave Benett/Getty Laura Dern has witnessed the devastating effects of COVID-19 firsthand. After losing a friend to the virus and seeing others people become severely sick, the Oscar-winning actress takes COVID-19 “very seriously.” “I've had friends who are on ventilators, who pulled through. I've known people of all ages who've been very sick. And we had one beautiful friend and artist who, who lost his life to it,” Dern, 53, tells PEOPLE. “So we certainly take it very seriously as, I pray at this point, everyone globally does.” Dern is urging people to follow “essential” health precautions to prevent the spread of COVID-19, from mask-wearing to social distancing to regular testing. “These are all essential,” she says, “but a mask really matters. It has really saved lives.” Laura Dern Makes Passionate Plea to Protect Environment and Immigrants Those precautions have helped Dern ease her anxiety about staying healthy, particularly as she continues to care for her mother, actress Diane Ladd, who is now 85 and particularly high-risk due to a lung condition. Dern and her two kids, daughter Jaya Harper, 16, and son Ellery Harper, 19, regularly get tested for COVID-19 so they can visit Ladd and Dern’s father Bruce, who both live nearby her home in Los Angeles.

I feel blessed that I have people that need me to take care of them. I think that serves us and makes us stronger somehow, that we need to be strong for others.” Laura Dern Makes Chicken and Dumplings with Mom Diane Ladd and 2 Kids While Self-Isolating Dern has been using LetsGetChecked, an FDA-approved, at-home COVID-19 testing kit that she learned about when Jurassic World: Dominion resumed filming this summer and she needed to be tested regularly.
