The result showed that laughter therapy was helpful in improving quality of life and cancer symptoms in some areas for cancer survivors. Improvements were seen in the area of depression, anxiety and stress levels. There were limited harmful side effects. Laughter therapy should be used in conjunction with other cancer treatment. [40]
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
[40] [41] However, several studies have supported the hypothesis that the runner's high is due to the release of endocannabinoids rather than that of endorphins. [42] Endorphins may contribute to the positive effect of exercise on anxiety and depression. [43] The same phenomenon may also play a role in exercise addiction.
Depression may be related to the same brain mechanisms that control the cycles of sleep and wakefulness. Depression may be related to abnormalities in the circadian rhythm, [24] or biological clock. A well synchronized circadian rhythm is critical for maintaining optimal health.
Relaxation techniques are often used as mood-repair strategies to help an individual achieve a level of calm and reduce the stress or tension that can come from negative moods. These techniques are often very methodical in their approach and can be actively engaged by willing participants who are aware of how to enact them. [ 10 ]
The constant search for approval may cause mental health issues such as anxiety or depression and when untreated can lead to suicide in extreme situations. [8] Laughter can evolve as a medium for self-preservation, detaching the individual from any adversity faced allowing for perceived control over uncomfortable situations.
Gelotology (from the Greek γέλως gelos "laughter") [1] is the study of laughter and its effects on the body, from a psychological and physiological perspective. Its proponents often advocate induction of laughter on therapeutic grounds in alternative medicine. The field of study was pioneered by William F. Fry of Stanford University. [2]
The neurotrophic hypothesis of depression [1] proposes that major depressive disorder (MDD) is caused, at least partly, by impaired neurotrophic support.Neurotrophic factors (also known as neurotrophins) are a family of closely related proteins which regulate the survival, development, and function of neurons in both the central and peripheral nervous systems.
