(a) Two health problems the student might develop from prolonged tablet use:

• Neck pain from looking down at the tablet screen held at a low angle for extended periods. This posture forces the neck to bend forward, placing strain on the cervical spine and surrounding muscles. [1]
• Eye strain from viewing a small, bright screen at close range for long periods. The eyes must continuously focus at a short distance, and the blue light emitted by the screen can increase fatigue. [1]

(b) Two precautions the student should take to reduce these health risks:

• Place the tablet on a stand or prop it at an angle so the screen is closer to eye level, reducing the amount of neck bending required. [1]
• Reduce the screen brightness to a comfortable level and enable a blue light filter (night mode) in the evening to reduce eye strain and limit the impact on sleep patterns. [1]

(c) The health risks of using a tablet differ from a desktop computer in the following ways:

• A tablet is typically held or placed on a lap or table at a low angle, which leads to poor neck posture as the user looks significantly downward. A desktop computer monitor can be positioned at the correct height and distance, reducing neck strain. [1]
• However, a desktop computer's fixed setup can cause more back problems if the chair is not properly adjustable, because the user is locked into a seated position at a desk for longer periods. A tablet's portability allows the user to change position, but that same flexibility means the posture adopted is often poor. [1]
