Step-by-step explanation:
The concept being described in the question is meditation. Meditation is known for its therapeutic use of time, providing refreshment for the mind and body, and aiding in the development of a positive attitude. It comprises various techniques, some of which include sitting upright in a relaxed position, being in a quiet environment, repeating a mantra, and focusing on pleasant thoughts. Stress reduction through meditation can improve physical and mental health by reducing blood pressure, enhancing sleep quality, and aiding in mood, anxiety, and pain management. The relaxation response technique, combining meditation with relaxation strategies, demonstrates its effectiveness in reducing sympathetic arousal and has been used to treat individuals with high blood pressure.
Stress reduction techniques also include exercise, which is beneficial for both physical and mental health. Physically fit individuals are more resistant to stress and recover more quickly from its adverse effects. Moderate amounts of stress, or eustress, can even be beneficial, as it is associated with positive feelings and optimal health, and can also enhance learning and memory.
