What to do about it in South Houston
- A sunrise alarm clock is worth considering if you get up at 7:00 am or earlier: 23 weekday mornings here are still properly dark at that hour, mostly between Sep 7 and Apr 9.
- Daylight alone gives little reason for a light therapy lamp here. Getting outside in the 7:12 am to 5:26 pm window on the shortest day does more than most people expect.
- If you head home at 5:30 pm, the sun has already set from Nov 9 to Dec 25: worth checking your bike lights and porch light before Nov 9.
