The immune system is a network composed of cells, organs, protein and antibodies, which can protect the body from bacteria, viruses and parasites. It not only works when people are sick, but also fights the virus every day. How to enhance immunity and make the body strong from the inside out is more important. The British "Mirror" summarized this.

1. Add seasoning to cooking. Season the food with garlic, onion, ginger and pepper. They have antioxidant, detoxifying and antibacterial properties.

2. Drink green tea. Drinking plenty of water can keep enough water in the body and help eliminate toxins and other bacteria that may cause diseases. Drinking tea in moderation can make you healthier. Although the antiviral effect of tea leaves remains to be confirmed, theanine in it can make people feel happy, resist aging to some extent and promote intestinal health.

3. Ensure adequate sleep. Ensuring 7-9 hours of high-quality sleep every night can increase the number of T cells, which can fight infection in the body. A study found that sleeping less than 4 hours every night consumes 70% of the body's natural killer cells (an important immune cell).

4. Reduce stress. In daily life, the brain and the immune system are in constant communication. When we feel stressed, the brain will produce more cortisol, which will prepare the body for emergencies. However, doing so will inhibit the function of the immune system. Try to do more relaxing exercises, such as yoga, deep breathing or meditation, and keeping a positive and optimistic attitude can also be very helpful.

5. Keep warm. Some viruses are more contagious at low temperatures. So be sure to wear warm clothes when you go out to avoid catching a cold and having a fever.

6. Use some essential oils. Lemon has strong antibacterial properties, which can stimulate the production of white blood cells, thus fighting infection. Dropping 6 drops of lemon essential oil into the essential oil diffuser is expected to enhance the function of immune system.
