(NC) For older adults, influenza is often more than just a seasonal illness—it can be serious and potentially life-threatening. As we age, our immune systems naturally weaken, making it harder to fight infections. This puts seniors at a higher risk of influenza-related complications and hospitalization.

The flu can also affect more than just the lungs. In fact, it can act as a silent trigger for cardiovascular events, increasing the risk of stroke up to eight times and heart attack up to 10 times following infection. For many seniors living with chronic conditions such as diabetes or hypertension, influenza can make these conditions worse and potentially lead to more serious health challenges.

In Canada, older adults account for nearly half of flu-related hospitalizations. For some, the flu’s impact can last well beyond the illness itself. About one in five seniors who are hospitalized with the flu experience a decline in their ability to carry out daily activities, which can impact their independence and quality of life.

Here are some simple, practical steps you can take to help lower your risk and stay protected this flu season.

• Consider the higher-dose vaccine tailored for seniors: According to Health Canada, vaccination is still the most effective way to reduce the risk of severe illness, hospitalization and complications. But because the immune system weakens with age, standard-dose vaccines may not always provide the same level of protection in older adults. Higher-dose vaccines designed specifically for seniors help generate a stronger immune response to protect against serious illness.
• Keep your distance when sick: Limiting close contact with others can help prevent spreading illness. Stay home when possible, and encourage family members and visitors to avoid coming over if they’re sick.
• Wear a well-fitting respirator or mask: Respirators and masks act as a barrier and can filter out respiratory particles, adding an extra layer of protection.
• Improve indoor ventilation: Opening windows or increasing ventilation can help reduce virus spread indoors.
• Practice good hand hygiene: Wash hands frequently with soap and warm water for at least 20 seconds, especially after being in public places. If soap and water aren’t available, use an alcohol-based sanitizer.
• Cover your coughs and sneezes: Use a tissue or the crook of your elbow, and dispose of tissues right away.
• Clean high-touch surfaces: Regularly disinfect germ-carrying surfaces such as doorknobs, phones and countertops.
