Even when advancing the time for sleep does not really reduce, only when advanced to a substantial degree 6 hours may work, then perhaps 5.
When your practice routine has mantric elements, then this will have the greatest effect on decreasing the need for sleep or in better words, to compensate lack of sleep. Still your body will be thankful if it is allowed to sleep for as long as it needs
The kind of work you do also has a great influence on the need of sleep. If possible, attune your working environment and content in a way that more life energy is in it, examples given:
If the work is mainly inside buildings, try to transfer elements from it to the outisde where you have more bodily motions, more fresh air and contact with the sun.
If working inside is unavoidable, look for a place at a big window where you will see the sun, trees, nature etc.
If that is also not possible, bring in some trees and plants into the office rooms, working rooms etc. Communicate with those who can decide on changes to check for air quality and ways to optimize it, like humidity, oxygen rate, etc.
Whenever possible take your breaks in places where life is flowing
Besides all of this, you may need to optimize the food you eat and the water you drink aswell, from those that take away your energy to those that give you energy.
A special hint for you, you can look into the topic of ketogenesis, ketosis and keton bodies, which if applied correctly will provide you with unfluctuating and continuous energy the whole day. I had intentions to write more about it in these forums, but am still in testing different aspects of it. In general the results so far were very good (= Still you will need sleep, but your energy supply will always be nr.1
Peace and happy practice despite all demands of daily life!
