Sleeping Problems
Computer Screens emit blue light, which suppresses melatonin production, making it harder to fall asleep. Excessive
screen time also is one of the reasons that disrupt the body's natural sleep-wake cycle leading to difficulty in falling
asleep or staying asleep. All these also may lead to physical discomfort such as eye strain, headaches, and muscle
tension, making it harder to relax before bed.
To avoid Sleeping problems you should:
• Avoid Screen Time Before Bed: Stop using computers and other screens at least an hour before going to sleep.
• Protect Your Eyes: Use blue light filters on devices or wear blue light-blocking glasses.
• Create a Relaxing Routine: Engage in relaxing activities before bed, such as reading a book or taking a warm bath,
to signal to your brain that it's time to wind down.
Practice mindfulness or relaxation techniques to manage stress levels. Consider limiting exposure to stressful content
close to bedtime.
