Your immune system is your body’s natural shield against cold and flu so it’s important to boost your immunity to help your body prepare for the cooler months. Good news, there are simple steps you can take every day to protect yourself from getting sick.

The home doctor experts at House Call Doctor have some ways that you can boost your immune system.

Get your flu jab

The flu can affect anyone, even if you are fit and healthy, so the best way to protect yourself is by getting an annual flu vaccination. Each year, the flu vaccine changes to combat new strains of flu, so it’s important to get a new one every year.

Maintain basic hygiene practices

Viruses can survive for some time outside the human body and can be easily transferred from person to person through contact. The most effective way to protect yourself from germs is through basic hygiene practices. Make sure you use warm water and soap when washing your hands for at least 20 seconds. Also make sure to keep your home clean by disinfecting highly touched surfaces and devices.

Get plenty of sleep

Sleep is a natural immune booster. Try to improve your sleep hygiene to increase the quality of your sleep. While you sleep your body heals and resets itself to give you energy the next day. It also helps your body fight infection.

Hydration is key

Hydration has many benefits for your entire body. Drinking lots of water is important to help flush toxins from the body and keep mucus in the respiratory tract. If you have a cold or the flu, the mucus helps fight the infections.


Regular exercise boost blood flow and burns calories which is good for your immune system. White blood cells are your body’s first line of defence when it comes to fighting infection and illness.


Eating a balanced diet is important for a healthy immune system. Focus on eating whole foods, fresh fruit, vegetables, nuts and seeds. If you are concerned about lacking nutrients in your diet, consider a supplement. It is important to consult your GP or healthcare professional for further advice.
