Healthy Habits to Help Support Your Immune System

Supporting your immune system becomes especially important during the colder months. One of the best ways to help your body stay well is by maintaining a healthy, balanced diet.

You likely already know the basics: eat plenty of fruits and vegetables, limit excess sugar and unhealthy fats, and avoid excessive alcohol. Along with good nutrition, a few simple habits can help give your immune system additional support throughout the winter season.

Here are seven easy ways to help support your immune health.

1. Get a Good Night’s Sleep

Quality sleep plays an important role in supporting the body’s natural defense systems. Research suggests that most adults need seven to eight hours of sleep per night to support a healthy immune response.

Even when your schedule is busy or you’re traveling, prioritizing sleep whenever possible can help your body function at its best.

2. Stay Hydrated and Sip Tea

Proper hydration helps keep mucous membranes moist so they can function effectively as part of the body’s natural defense system.

In addition to drinking water, hot beverages such as black or green tea with lemon and honey can offer added comfort during the winter months. The warm steam from tea may also help stimulate the tiny hair-like structures in the nose, known as cilia, which help filter particles from the air we breathe.

3. Make Sure You’re Getting Enough Protein

Protein is essential for many bodily functions, including immune system activity. Diets that are too low in protein may weaken immune responses over time.

Include protein-rich foods throughout the day, such as:

• Fish

• Eggs

• Yogurt

• Lean meats

• Plant-based proteins

Balanced meals that include protein can help support overall immune health.

4. Wash Your Hands Frequently

Your hands come into contact with countless surfaces every day, including door handles, handrails, elevator buttons, and shared objects.

Washing your hands frequently with warm, soapy water — or using hand sanitizer when soap is unavailable — can significantly reduce the spread of germs.

5. Avoid Touching Your Face

Studies suggest that people touch their face several times per hour, often without realizing it.

Each time your hands touch your eyes, nose, or mouth, you may transfer germs from surfaces directly into the body. Being mindful of this habit can help reduce unnecessary exposure.

6. Clean Your Phone Regularly

Most of us carry our phones everywhere — setting them on different surfaces and touching them frequently throughout the day.

Regularly wiping your phone with disinfecting wipes or sanitizer can help reduce the number of germs that accumulate on its surface and potentially come into contact with your face.

7. Get Regular, Moderate Exercise

Moderate exercise helps support overall health and may also benefit the immune system.

If you are not currently active, start slowly and gradually build up to a consistent routine. Activities such as walking, cycling, or light strength training can help support both physical health and immune function.

Support Your Immune System All Season Long

Maintaining healthy habits — including good nutrition, proper hydration, regular exercise, and quality sleep — can help give your immune system the support it needs throughout the winter months.

Small, consistent lifestyle choices can make a meaningful difference in helping your body stay strong and resilient.
