If you work at night or perform consistent shift work that makes it hard to stay awake at home or at work, light can beneficially impact your lifestyle by helping you readjust your circadian rhythm and by giving you a much-needed energy boost.
Use AYO just before starting work. If you begin to get drowsy during work hours, use AYO again during your work break.
! Do not use AYO 1-2 hours before going to bed after your shift and try to sleep in a quiet, cool and dark sleep environment.
