Images of thousands of people lining up to donate blood following the shooting in Orlando reminded people in Connecticut of its importance.
Tuesday is World Blood Donor Day.
A number of groups across the state said they are holding blood drives.
The American Red Cross encouraged people to take an hour and donate.
"Very minimal time of your day and you're helping probably save some lives," Todd Guay, who is a regular donor, said.
The organization said regular donations are needed to maintain a stock that is immediately available.
Blood given in emergencies still has to be tested, which takes a few days.
"You never know when you or someone else that you know may need blood," said Stefanie Arcangelo, American Red Cross of Connecticut and Rhode Island. "So it's important to make sure that blood is available."
Naomi Lindower stopped by a blood drive in Rocky Hill on Tuesday morning unaware that today happens to be world blood donor day. Lindower said Sunday's shooting was a somber reminder of something she considers a responsibility.
"With Orlando I just felt that, I knew I was due so I thought I would come out and find a place to donate today," Lindower said.
Lindower said she hopes those who stepped up so quickly in Orlando will become regulars at donation centers.
"It's amazing, but I hope that those people will continue to give blood and not just do it this one time," Lindower said.
