The human mind processes more than 50,000 thoughts every day. Every thought is a creative seed that prompts the universe to manifest the focus of that thought. That's why your dominant thoughts become what you perceive as the reality of your life. These thoughts are a product of the programming in your subconscious mind.
For example, if your dominant thoughts are focused on the conflict between you and a coworker, that conflict will intensify every day given that the universe brings forth your 'desires,' whether conscious or unconscious. The universal laws, like cause and effect and the law of attraction, guarantee this result. Remember that the universe does not function in terms of good or bad (or what you want and don't want). The universe simply responds to the vibrational frequencies of your thoughts. The universal laws, being impartial and perfect, never fail to deliver (that is, to bring you) that on what you are focused. Good and/or bad are our interpretation of this universal delivery. Obviously, with all this creative activity between our minds and the universe at large, our Creator would have incorporated some method of respite into the human experience. We have come to know this as relaxation. Relaxation is very important in our lives because it helps reduce our stress levels and, consequently, improve our health. Too much work and mental activity mixed with negative emotions can lead to mental health problems, memory leaks and even heart attacks. Therefore, it is important for everyone to take at least a few minutes each day to practice relaxation.
Relaxation has become an important factor in the interaction between experts in fields related to medicine and the common population. For example, if you have visited a dentist, it is very possible that you heard the words "relax, this will just take a minute" - usually right before the dentist started to use the drill.
In situations of life and death, for example after an accident, one can hear the paramedics and the police tell the victims to be calm, to relax.
There are scientific studies that have shown evidence of many other benefits from the frequent practice of relaxation, such as a decreased risk of heart attacks, protection against mental health problems, improved immune system and memory. Today, stress levels are much higher than they used to be, so it is important to our health to reduce these malignant levels. An excess of the hormones adrenaline and cortisol in our body can cause the blood pressure to increase which causes the brain to behave differently. This causes anxiety.
More importantly, being relaxed is conducive to happiness.
