Managing Mucus and Chest Infections – A Senior’s Guide

Respiratory Health Blog Series | Blog 5 of 10

Older adults are more vulnerable to chest infections and mucus buildup – especially during cold seasons or if they have chronic lung conditions like COPD or asthma. Knowing how to manage mucus properly can help prevent infections and keep your lungs clear and strong.

Why Does Mucus Build Up More With Age?

As we age, the lungs’ ability to clear mucus becomes less efficient. This makes older adults more prone to:

• Thicker, harder-to-clear phlegm
• Night-time coughing or choking sensation
• Greater risk of infection if mucus traps bacteria

Chronic conditions like bronchitis, COPD, or post-viral fatigue may worsen this buildup.

Early Signs of a Chest Infection

Act quickly if you experience:

• Change in mucus colour (yellow, green or brown)
• Sharp chest pain when coughing or breathing
• Fever, chills or sweating
• Increased shortness of breath
• Feeling unusually tired or dizzy

These may signal a chest infection. Call 111 or contact your GP – antibiotics may be needed.

Reminder: People with COPD may be given a “rescue pack” to keep at home – including steroids and antibiotics. Know when and how to use it.

Tips for Managing Mucus at Home

• Stay hydrated: Aim for 6–8 glasses of water daily to loosen phlegm
• Use steam safely: A warm shower or bowl of hot water (with towel over head) can help
• Controlled huff coughing: Gently clear mucus without exhausting your chest
• Keep moving: Light movement like walking helps lungs drain naturally

Chest Physiotherapy and Mucus Devices

Ask your respiratory team or physio about:

• Postural drainage: Lying in positions that help mucus move
• Flutter devices: Hand-held tools that create vibrations to loosen mucus
• Oscillating PEP therapy: Blowing into resistance devices under NHS guidance

Nutrition That Supports Lung Defence

• Eat foods rich in vitamin C and zinc (peppers, berries, seeds)
• Include anti-inflammatory spices like turmeric and ginger
• Avoid excessive dairy if it thickens mucus for you (not true for everyone)

When to Seek Emergency Help

Dial 999 if you experience:

• Severe shortness of breath at rest
• Lips or face turning blue
• Sudden confusion or collapse
