Jidda warns against prolonged sitting, excessive screen exposure

A Senior Lecturer at the Department of Health Promotion and Environmental Health Education, University of Ilorin, Dr Kafayah Adeola Jidda, has cautioned staff members of the University and other Nigerians against prolonged sitting and excessive screen exposure, warning that both habits pose serious risks to health and productivity.
Dr Jidda gave this warning while discussing findings from her research, titled “Prolonged Sitting and Screen Exposure Among Staff: Small Habits, Big Health Impact.” She explained that prolonged sitting and excessive screen use could negatively affect physical health, mental well-being, and workplace performance.
Speaking with UNILORIN Bulletin in her office last Thursday (May 14, 2026), Dr Jidda described prolonged sitting as remaining seated for extended periods with little or no movement. She noted that the condition, also referred to as “sitting disease,” sedentary behaviour, or desk-bound living, can lead to several health complications.
According to her, excessive sitting contributes to poor posture, lower back pain, neck strain, and other musculoskeletal problems. She added that it also slows the body’s metabolism, reduces calorie expenditure, and increases the risk of obesity, Type 2 diabetes, and related metabolic disorders.
“The research shows that adults who sit for eight hours daily with little movement have a 20 per cent higher risk of early death compared to those who move regularly,” she said.
On screen exposure, Dr Jidda explained that excessive use of computers and mobile devices could result in digital eye strain, irritation, blurred vision, and headaches. She further warned that exposure to blue light, especially at night, could disrupt sleep patterns and affect overall well-being.
Beyond physical effects, she noted that prolonged sitting and screen exposure could also affect mental health, leading to fatigue, stress, reduced concentration, and burnout over time.
Dr Jidda stressed that the combined effects of both habits could reduce effectiveness in teaching and administrative duties due to discomfort, fatigue, and reduced alertness.
She advised staff members to adopt healthier routines by taking regular breaks to stand, stretch, or walk around during work hours. She recommended standing or walking for between 30 seconds and two minutes after every 30 minutes to one hour of sitting.
She also encouraged “walking meetings,” frequent blinking to reduce eye dryness, and the “20-20-20 rule,” which involves looking at an object 20 feet away for 20 seconds after every 20 minutes of screen use.
Dr Jidda further urged the management of the University to promote staff wellness through awareness campaigns and improved work environments. She said both academic and non-teaching staff have a role to play in fostering a healthier and more productive University community.
