Enjoy morning sunlight for 20-30 minutes preferably within the first 2-3 hours after dawn, if possible, outdoors, walking or other physical activity. This optimizes your melatonin production and sets an optimal sleep schedule. Full spectrum light boxes can be used if outdoors is not an option.
Avoid caffeine after 2 PM. Alcohol after 6 PM can cause sleep arousal in the hours after midnight when the blood level is returning to zero.
Avoid vigorous physical activity and screen time at least 2 hours before bed
If problems getting to sleep, try a warm bath or shower before bed
Try to keep the bedroom for sleeping or relationship with your loved one. Love making benefits sleep onset. Yellow spectrum lighting does relax us, lowers stresses and inhibitions.
The most restorative sleep tends to happen between 10 PM to 2 AM, but any sleep is beneficial.
Sleep cycles average 90 minutes, finishing with dreaming (REM sleep). Four cycles are usually enough to allow an alert/normal day. If you awaken after REM sleep and do not have time for another whole cycle, you will have a better day if you start your day then.
