I need to improve my sleep.  Give me a list of ideas for doing so.
* Make your bedroom darker, especially if daylight wakes you up in the morning.
* Make your room quieter, or use a white noise machine, if you are awoken by noises.
* If you find yourself getting too hot or cold, adjust your pajamas, bedding, or room temperature.
* Exercise during the day, but not too close to bedtime.
* Have a regular bedtime, as well as a bedtime routine beforehand.
* Avoid looking at computer, TV or phone screens for an hour or two before bedtime.
* Try to lower your stress levels.
* Give yourself enough time to sleep so that you don't need an alarm to wake up.
