Feeling tired after meditation can be frustrating, especially when you are trying to establish a regular practice. This feeling may be caused by a variety of factors including external environmental factors, and it can also be the result of pushing too hard during meditation. Trying too hard often leads to physical discomfort such as hard aches, eye strain and pain in the body.
It is common to feel drowsy during a meditation session because your brain waves can start to mimic those of sleep. However, it is important to remember that you will probably feel less and less drowsy as you continue to meditate regularly.
If you find yourself feeling sleepy during a meditation session, you can try to use your breath and other mindfulness exercises to regain focus. It is also helpful to be sure that you are practicing in a room that has good ventilation and that it is not too warm or dark. Many people also find that they can stay more awake during a meditation session if they are not alone.
Finally, you may want to try meditating at different times of the day. Some people feel more alert in the morning while others may be more energetic at night. The key is to choose a time of day that is best for you and then stick with it as much as possible. Over time, you will likely learn to better manage your energy and waking state, and the feelings of sleepiness during meditation should diminish.
