Soak yourself in warm water
Soaking yourself in warm water with Epsom salt has proven to be one of the most effective ways to treat a stiff neck. The warm water bath helps relax and reduce tension on tightened muscles, while the salt may help reduce inflammation and improve the rate of blood flow to the neck.
Take Frequent Breaks
Sitting in your car or at your desk may have negative effects on your body. It would help to get up every hour, move around, and do some light stretching to relieve yourself from any stress.
