Most people feel very relaxed. Some experience a significant decrease or freedom from long-term aches and pains. Many feel a little slowed down for a short period and then notice an increase of energy, heightened awareness and increased productivity which can last for days.
If you received a deep massage, you may be slightly sore the next day - much like a good workout at the gym. Sometimes a hot shower, or a soak in the tub can ease this soreness.
After your session you should increase your water intake a bit. Just a glass or two more than normal is usually fine. This helps keep your body's tissues hydrated and healthy.
