Bright Light

8 a.m. study participants will be exposed to Bright Light (4500 lx) Phillips Energy Light HF3319 for 30 minutes prior and during a 30 minute lasting exercise test with self-chosen exercise intensity on a bicycle ergometer.

The light exposure and time-trial will be performed in three repetitive exercise sessions 48h apart.

Group Type EXPERIMENTAL
