To determine the computer-related health problems that Alex may still be at risk for, we need to consider the potential issues that can arise from extended computer use, even when certain precautions are taken.
1. Musculoskeletal problems: While Alex takes measures such as sitting up straight and keeping his muscles relaxed, prolonged computer use can still put strain on the muscles, tendons, and joints, leading to potential musculoskeletal issues like neck pain, back pain, and repetitive strain injuries (RSIs).
2. Vision problems: Despite practicing good posture and taking breaks from the computer, Alex may still be at risk for vision problems due to prolonged screen time. This is because continuous exposure to the screen's blue light and the lack of natural light can lead to eye strain, dry eyes, blurred vision, and other visual discomforts.
3. Sleep problems: It is mentioned that Alex stays off his computer after 6 p.m., which is beneficial for reducing sleep problems. However, this statement alone does not provide sufficient information to confirm whether Alex follows good sleep hygiene practices, such as avoiding screen time before bed, maintaining a consistent sleep schedule, and creating a suitable sleep environment. Thus, it is uncertain if he is still at risk for sleep problems solely due to computer use.
4. Headaches: While headaches can be caused by various factors, including computer use, this question does not provide enough information to establish whether Alex is at risk for headaches due to his computer use.
Therefore, based on the given precautions Alex takes, the computer-related health problems he may still be at risk for are:
- Musculoskeletal problems
- Vision problems
However, it is essential for Alex to address these concerns and seek proper guidance and care from healthcare professionals for a more accurate assessment.
