It’s a very interesting question. A few suggestions - hopefully you’ll find this helpful.
There’s been interesting studies on the correlation between exercise and sleeping patterns. The suggestion suggests exercise significantly improves the sleep and helps individuals to fall asleep more quickly. This may sound over simplistic, but taking a few "walking breaks" during your work day (even short distances), using stairs instead of elevators, walking instead of taking the tube/bus are all “tricks” that can help. If you work out, i would exercise in the morning instead of evenings.
As you know, there is also a direct correlation between stress/anxiety levels and insomnia. While reducing stress levels is easier said than done, I would try the following tips for a few weeks to see if it helps:
- Increase your water consumption. Staying hydrated when you are low on sleep will help your body cope and recover
- Create a “winding down” period in your calendar at the end of each working day. Use this time to do work alone (no meetings)
- A few hours before going to sleep, switch off any smart-phones/tablets/computers
- Make your bedroom a technology-free zone. According to Harvard Medical School, "specific wavelengths of light can suppress the slumber-inducing hormone melatonin in the brain
- Eat regularly throughout the day, smaller meals 5-6 times a day and try having your last meal 4-5 hours before going to bed
- When you catch up on sleep, go to bed early, rather than sleeping in later
