Without enough sleep I find myself struggling—moving through my day the way it feels to move through water. Everything is harder and slower and I feel stressed all day because I have to push myself to focus and be alert. Besides the headaches this gives me, I have much less energy, am less creative, and can only concentrate on one thing at a time instead of being able to handle several things at once. Moreover, when I am so low on energy, I tend to isolate myself and not interact as much with friends or to participate spontaneously in conversations. I'll usually resort to having coffee to try and boost my energy and alertness levels but the caffeine high only works for a short period. Afterward, I'll be even more tired because my body has been running on overdrive. It's not a good way to operate.
Over the years, I've learned that the best thing I can do for my health and for enjoying my life is to get at least eight hours of sleep a night (individuals vary in the number of hours for optimal sleep). Even a deficit of half an hour a night makes a difference. Because I know this about my body and because I cannot enjoy the moments of my days—ordinary or otherwise—if I am not fully present, there are other areas of my life I will skimp on before I skimp on sleep. For example, I will consciously choose to give up late-night or early-morning activities to make sure I get enough sleep. This isn't the best way to operate either but the discomfort I feel never equals how bad I feel to have to slog through on too little sleep. In terms of affecting the quality of my work, sleep is the single most important tool I have.
I love sleeping.Sleep well.Stay healthy !! :P
