Acupressure, according to, is "an ancient healing art using the fingers to gradually press key healing points, which stimulate the body's natural self-curative abilities."

Which acupressure points may help you relieve stiffness? 
The two points recommended by Michael Reed are GB34 and ST36. 
How do these acupressure points work?
According to Modern Reflexology, GB34 "is situated on the side of the leg, right below the knee, slightly in front of the tip of the outer leg bone." ST36 can be located four finger lengths below the knee cap and one finger width to the outside of the leg. Reed recommends briskly rubbing GB34 and ST36 every day to help relieve muscle stiffness.
Besides relieving stiffness, Modern Reflexology states that GB34 may help relieve nausea, vomiting, sciatic pain, hip pain and jaundice. Natural Herbal Remedies reports that ST36 is supposed to be critical in toning muscle, helping with digestion, relieving fatigue and alleviating menstrual cramps.

Making sure that you are warm and don't sleep in a draft is also beneficial. Taking a hot shower can help relax tight muscles and increase the flow of blood.
