Dr Amir Khan has shared three simple exercises that anyone can do at home or at work to counter the dangers of prolonged sitting.
The general practitioner warned that spending extended periods seated significantly increases the risk of developing cardiovascular disease, diabetes and depression. According to the doctor, these health risks remain elevated even for people who make time to exercise during their leisure hours.
His guidance, reported by the Mirror, highlights how modern deskbound work routines can quietly undermine physical well-being. Khan explained that moving for just a few seconds every 30 to 60 minutes can deliver substantial health improvements. Taking regular short pauses helps improve blood circulation, increases the body's sensitivity to insulin, eases aches in the back and shoulders, and gives workers a noticeable boost in energy and mental focus.
Insulin sensitivity refers to how effectively the body's cells respond to insulin to clear glucose from the bloodstream. When people sit still for prolonged periods, muscle contractions drop and cellular responsiveness slows, whereas even brief bursts of activity encourage muscles to absorb glucose and keep metabolic processes functioning efficiently.
Movement breaks at your desk
The physician recommended beginning with simple upper body movements while remaining seated. Khan explained that because he spends long stretches hunched over his own consultation desk, he regularly leans back in his chair, relaxes his posture, rolls his shoulders backwards and forwards, and gently moves his head up and down. He noted that these basic adjustments help release built-up tightness across the chest and neck.
For his second exercise, Khan advised workers to stand up away from their chairs at regular intervals. He suggested lifting each leg in turn and rotating the ankles in different directions, an action that stimulates blood flow through the lower limbs and prevents stiffness after hours of immobility.
Khan is a National Health Service doctor and author who frequently appears on British television to promote accessible public health advice. Health professionals have long pointed out that remaining sedentary for six to eight hours a day slows metabolism, weakens posture and places undue strain on the spine.
Side bends and seasonal nutrition
The third technique suggested by Khan targets flexibility through the torso. He recommended performing gentle side bends while reaching the opposite arm down along the side of the body. The doctor noted that this movement comfortably stretches tight muscle groups and simply feels good to do during a tiring working day.
The advice on staying active during desk hours comes alongside wider guidance on maintaining physical health throughout the year. Nutritionist Pauline Cox previously outlined key dietary choices designed to help protect the body against common winter illnesses such as colds and influenza. To support the immune system in functioning normally, Cox recommended eating meals containing oily fish, eggs, dairy products and legumes.
Dietary nutrients and physical activity work together to support overall resilience. While nutrient-dense foods supply the building blocks for immune cells, regular physical movement keeps the vascular system active and reduces physical fatigue. Incorporating micro-breaks into the working day offers desk workers an achievable way to protect their long-term cardiovascular and metabolic fitness without needing specialist equipment or leaving their workspace.
