A network of tissues, organs and vessels

Circulating a clear fluid called lymph which contains white blood cells that help fight infection, the lymphatic system performs three main functions. First it returns excess fluid, proteins and cellular waste from body tissues to the bloodstream, helping to prevent swelling. It also plays a key role in immune defence by filtering lymph through lymph nodes and specialised organs, where bacteria, viruses and other potentially harmful substances can be identified and removed. In addition, the lymphatic system absorbs fats and fat-soluble vitamins from the digestive tract and transports them into the bloodstream.TOGETHERSeveral structures work together to keep the lymphatic system functioning effectively.Lymph is a clear fluid that carries white blood cells, nutrients and waste products through the body.Lymphatic vessels form a network of thin tubes that transport lymph back towards the bloodstream.Lymph nodes are small, bean-shaped structures found throughout the body, particularly in the neck, armpits and groin. They act as filters, trapping harmful substances and supporting immune responses.Other important lymphatic organs include the spleen, which filters blood; the thymus, where certain immune cells mature; the bone marrow, which produces blood and immune cells; and the tonsils and adenoids, which help defend against inhaled or ingested germs.BLOCKEDA blockage in the lymphatic system, known as lymphoedema, is most commonly identified by persistent swelling, usually in the arms, legs, fingers or toes. Other symptoms may include a feeling of heaviness or tightness, reduced flexibility in nearby joints, and changes in the skin, such as thickening or hardening.People may also notice that clothing, shoes or jewellery feel tighter than usual. In some cases, the skin may retain an indentation after pressure is applied.MOVESUnlike the circulatory system, the lymphatic system does not have a central pump. Instead, lymph is moved through the body by skeletal muscle contractions, deep breathing and gravity. The fluid eventually drains into veins near the collarbone before re-entering the bloodstream.DRAINPhysical activityRegular movement helps stimulate lymph flow because muscle contractions act as a natural pump. Walking, swimming, cycling and yoga are often recommended as gentle, low-impact options.Deep breathingSlow, diaphragmatic breathing creates pressure changes within the chest and abdomen that can encourage lymph movement through the body's largest lymphatic vessels.Lymphatic massageManual lymphatic drainage is a specialised massage technique designed to encourage the movement of lymph fluid from areas of swelling towards functioning lymph nodes.Dry brushingSome practitioners recommend dry brushing the skin using gentle strokes towards the heart. While evidence is limited, it may help stimulate circulation and provide exfoliation.HydrationDrinking enough water helps maintain normal fluid balance and supports the movement of lymph throughout the body.DRINKThere is no single drink that can "cleanse" or "drain" the lymphatic system. However, staying well hydrated is important because lymph is largely composed of water.Warm water with lemon is often recommended as a healthy hydration option. Green tea contains plant compounds known as catechins, which may support circulation, while ginger tea has recognised anti-inflammatory properties. Herbal infusions such as cleavers, burdock root and dandelion root are traditionally used to support fluid balance, although scientific evidence for their effects on lymphatic drainage remains limited.EATA balanced diet that includes adequate protein can help support lymphatic function. Good sources include eggs, fish, poultry, lean meat, beans, lentils, nuts and seeds.Plant-based protein sources also provide unsaturated fats, which are associated with cardiovascular and overall health benefits.ABCNo vitamin can directly "clear" lymph nodes. However, vitamins A and C play important roles in immune function and may help the body respond to infections that can cause lymph nodes to become enlarged.MOVEBecause the lymphatic system relies on movement to transport fluid, exercises that combine gentle activity with deep breathing can be beneficial.Diaphragmatic breathing: Place your hands on your abdomen and take slow, deep breaths, allowing the stomach to rise and fall with each breath.Walking, cycling or swimming: These activities engage large muscle groups and help prevent fluid pooling.Ankle pumps: While sitting or lying down, point your toes away from you and then pull them back towards your shins. Repeat several times.Shoulder rolls and neck stretches: Gentle movements of the shoulders and neck may help stimulate lymphatic drainage around the collarbone and upper chest.Marching in place: Lifting the knees while swinging the arms engages both upper and lower body muscles, helping to encourage lymph movement.
