This differs from person to person.
A stimulation session takes 30 minutes and can be done whenever works best for you. Whether that be while you eat breakfast to start your day, while replying to emails at work, or even reading while winding down for bed. Flow is a wireless headset that can go wherever you go. Just remember to charge it before use.
Please note Flow should not be used while operating heavy machinery, exercising, or near water.
Some users have reported feeling energized after stimulation and for those, it would be recommended to use Flow earlier in the day. Some users have reported feeling sleepy after stimulation and for those, it would be ideal to use Flow before going to bed.
Most users do not feel sleepy or energized after a stimulation so it does not matter when the stimulation takes place during the day.
