As people attend group gatherings, crowd into stores, and travel during the holiday season, there’s usually an uptick in the spread of viruses and other illness.

Clinicians at ZipClinic Urgent Care in Denver are already seeing an uptick in upper respiratory infections and stomach bugs. And while the flu season isn’t yet in full swing, some parts of the country are starting to see more influenza cases.

“There are plenty of preventative measures—as simple as handwashing—you can take this season to avoid getting sick or hurt,” said Aniela Johnson, General Manager at ZipClinic. “But if you do fall under the weather during the holidays, you can get in at ZipClinic even during evening hours, on weekends, and on the holidays.”

ZipClinic centers in Denver, Aurora and Westminster will be open from 10 a.m. to 4 p.m. on Christmas Day and New Years Day.

Here are five tips from the Centers for Disease Control and Prevention for staying healthy this time of year:

Wash your hands often.

Keeping hands clean is a vital step in avoiding germs. Wash hands with soap and clean running water for at least 20 seconds. Cover your mouth and nose with a tissue— or use your sleeve or elbow—when you cough or sneeze.

Stay warm.

Cold temperatures can cause serious health problems, especially in infants and seniors. Stay dry and dress in layers.

Manage stress.

Avoid letting the holidays wreak havoc on your health and pocketbook. Don’t overschedule your time and keep spending in check. Try to maintain balance of work, home, and play time. Keep relaxed and stay positive—and be sure to get enough sleep!

Prevent injuries.

Both children and adults are at high risk for injuries this time of year. Keep an eye out for choking hazards and other dangers accessible to children. And use proper step stools instead of climbing on furniture when hanging decorations. Keep safety in mind when trying out new gifts, and police fire hazards around your home.

Eat health, stay active.

Balance the rich foods often consumed around the holidays with fresh fruits and vegetables, and other lighter fare. Find fun ways to stay active, such as dancing to holiday music or going sledding with the kids. Aim for 2.5 hours of being active each week. Kids and teens should be active for at least an hour a day.
