Changes in sleep patterns

Potential impact at work:

• Impact on night driving.
• Implications in case a worker needs to move between light and dark working environments

Addressing the changes through safety and health management:

• Improve contrast between objects by increasing the lighting levels.
• Avoid shades of blue, blue on green or blue on black in work environment.
• Install local lighting or task lighting that does not interfere with the visual field of others – if possible make it individually adjustable.
