Your immune system is your body's defense against infection and disease. It is made up of a network of cells, tissues, and organs that work together to protect you from harm.

There are many things you can do to keep your immune system strong, including:

• Eating a healthy diet: Eating plenty of fruits, vegetables, and whole grains can help to provide your body with the nutrients it needs to support a healthy immune system.
• Getting enough sleep: When you sleep, your body produces important immune cells and proteins. Aim for 7-8 hours of sleep per night.
• Exercising regularly: Exercise can help to boost your immune system by increasing the production of white blood cells. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
• Managing stress: Stress can weaken your immune system. Find healthy ways to manage stress, such as yoga, meditation, or spending time in nature.
• Avoiding smoking and excessive alcohol consumption: Smoking and excessive alcohol consumption can damage your immune system. If you smoke or drink alcohol, quitting or cutting back can help to improve your immune function.
• Taking supplements: There are a number of supplements that can help to support your immune system, including vitamin C, zinc, echinacea, elderberry, and probiotics.
