There are various signs that your immune system is weak. Perhaps you’re ill more often, have less energy, or suffer from certain infections that sometimes recur. If you’re experiencing these issues, it’s important to boost your immune system. Read on to find out the best ways to do this.

What are the symptoms of a weak immune system?

When your immune system is weak, your body struggles to defend itself against viruses and bacteria. This usually means you get ill more easily and find it harder to recover. Here are some other signs of a weakened immune system:

• You get ill or catch a cold easily
• You get tired easily or have low energy levels
• You have recurring infections, such as a sore throat or bladder infection
• Your wounds heal slowly or poorly
• You don’t recover well after being ill

There can be several causes for a weakened immune system. Usually, it is a combination of various factors and lifestyle choices.

Why might you have a weakened immune system?

A weakened immune system doesn’t usually occur if you lead a healthy lifestyle. It often arises from a combination of stress, lack of sleep and an unhealthy diet. It can also be caused by not getting enough exercise, or conversely, not resting sufficiently after physical exertion. Smoking, excessive alcohol consumption, digestive problems and long-term illness or recovery can also contribute to this.

7 ways to boost your immunity

1. Get enough sleep and rest

A good night’s sleep is vital for your immune system. Whilst you sleep, your body recovers and immune processes are activated. Aim for at least 7–9 hours of sleep per night and maintain a regular sleep pattern.

2. Eat a healthy and varied diet

A diet rich in vegetables, fruit, protein and healthy fats supports your immune system. Important vitamins and minerals such as vitamins C and D, and zinc, play a major role in this.

3. Reduce and manage stress

Prolonged stress weakens your immune system. Relaxation, breathing exercises, walking or mindfulness can help to lower your stress levels and keep your body better balanced.

4. Exercise regularly, but not too intensely

Gentle exercise such as walking, cycling or yoga stimulates blood circulation and supports your immune system. On the other hand, exercising too intensely can actually be counterproductive, so don’t overdo it and make sure you allow enough time for recovery.

5. Drink plenty of water

Drinking enough water helps your body flush out waste products and supports all bodily functions, including your immune system.

6. Get enough sunlight and vitamin D

Sunlight helps your body produce vitamin D, which is important for a properly functioning immune system. This is particularly important in autumn and winter, as there is less sunlight during these months. If you have a vitamin D deficiency, you can also take supplements temporarily during these periods.

7. Use red light therapy

Red light therapy administered through the nose is increasingly being used to support the immune system. It stimulates cell activity in the blood, thereby helping to boost immunity and promote optimal recovery.

How does red light therapy help boost immunity?

Red light therapy is increasingly being used as a natural way to support the body. It works at a cellular level and can therefore help strengthen the immune system.

With intranasal application (via the nose), the light is directed at an area rich in blood vessels and directly connected to the immune system. This has several benefits for the immune system:

• It supports energy production within the cells, enabling the body’s natural processes to function more effectively
• It supports the body’s natural ability to heal
• It helps maintain a healthy balance in the body and is often used to complement a healthy lifestyle
