Headaches

Headaches can be closely linked to musculoskeletal problems, particularly those involving the neck, shoulders,
and upper back. These types of headaches, often referred to as tension-type headaches are typically caused
by muscle tension, poor posture, and other musculoskeletal factors. You should make an effort to maintain a
straight neck while using the computer, and remember to take regular breaks.

Obesity

Excessive time spent on computers can result in a lack of physical activity and exercise. For children, prolonged
use of computers or other electronic devices is a significant factor contributing to obesity. It’s important to take
breaks and incorporate some physical activity before returning to your work.

Stress Disorders

Prolonged computer use can lead to negative health effects and increased workplace pressure, which may result
in stress. If left untreated, prolonged stress can elevate the risk of developing more serious health issues. The
various symptoms of stress may include a decreased attention span, difficulty concentrating, dizziness, and
burnout. To address this issue, prioritize your health and work to prevent future health problems by exploring
various treatment options for any stress you experience. Also, consider practices such as yoga, natural remedies,
or medications prescribed by a healthcare provider to help manage your stress.
