Tune in periodically for slow, deep, rejuvenating breaths. Improve your sleep patterns. Your body gets its most restful sleep before 11 pm, so adapt your bedtime to those hours. Establish a regular wake-up time, even on the weekends. Avoid alcohol and smoking, which interfere with good sleep.
Studies show that even long-married people get a more restful night sleeping by themselves.
After a long day of sitting, your lower back gets extra tight. Slowly bend your right knee towards your chest, then let it fall to the left, still bent. There should be a gentle stretch across your lower back and up through your upper body. Repeat on the other side.
