I can bet many of you only sleep for 6 hours a day (or night ) and work for more than 10 hours per day. How do you do that ? Owing to my liver problem , I can't take coffee or ordinary tea they sell in India and I can't afford green tea. I want to wake up at 4:30 o clock in the morning and go to bed at 11. During the whole day, I don't want to fall asleep. I never tried it before , I am going to start from today. What do you do get rid of sleepiness or drowsiness ?
Most human beings need 8 hours of sleep to maintain active brain function. Some can manage with as little as 4 while others need 10. It depends on the person. Sleeping routines also vary wildly based on the individual.
There have been studies to show that sustained overworking beyond a certain point actually reduces your productivity. Taking naps improves your alertness and ability to retain memory. As long as you focus on your job during an 8 hour period, you should be able to achieve a lot in that timespan.
How someone `perceives` your productivity is usually the crux of the problem. Perceived and actual productivity are different problems to solve in the work place.
I sleep for more than 6 hours a night. In fact 6 is my lower limit that I can do for a day or two while still remaining functional. I also don't work for 10 hours a day (unless you count volunteer "work."). I'm very focused and productive when I'm working though and work quickly.
How much sleep do you get now?
As far as coffee, I don't drink any either. I also don't drink soda. One natural way to boost your energy is to go for a brief walk or jog (or some other exercise) in the morning. I take a longer route to work so I can go for a 10 minute walk "on the way." This is a great investment as it gets me going for the day. As a short term energy boost, sugar helps. But it only helps for a short period of time so I wouldn't recommend using it as a solution to your problem.
