What to do about it in Pierre
- A sunrise alarm clock is worth getting here: on 133 weekdays the sun is still at least 20 minutes from rising at 7:00 am. Dark mornings run from Aug 31 to Apr 13, so set it up before Aug 31.
- On daylight grounds there is a strong case for a light therapy lamp: 55 weekdays start and end in the dark. Use it in the morning, and if winter low mood is the reason, ask a doctor before you rely on one.
- If you head home at 5:30 pm, the sun has already set from Nov 2 to Jan 15: worth checking your bike lights and porch light before Nov 2.
