Millions are plagued by insomnia across the globe, and they may require a technique to control it in order to sleep better. The goal of this research is to investigate the impact that five diverse contemplative techniques (mindfulness meditation, transcendental meditation, loving-kindness meditation, yoga nidra, and guided imagery) have had on a person suffering from insomnia via sleep. A total of 2,000 individuals performed each strategy for eight weeks during a randomised controlled trial (RCT), and we evaluated sleep quality using the Pittsburgh Sleep Quality Index Questionnaire (PSQI) and actigraphy. Analysis of variance and Tukey's HSD test were done on the findings using descriptive statistics for data summation. Overall, transcendental meditation showed a mean increase in sleep quality of 33.5%, which was greater than that with loving kindness meditation (29.4%). Yoga Nidra research had the second largest percentage change impact on average for bettering sleep characteristics; however, it is likely influenced by this study as well. The improvement in the mindfulness meditation and guided imagery was essentially poor. The study provides light on precisely how much diversity exists in terms of the benefits produced by various practices and highlights the necessity for personalised meditation therapies. This research contributes to the literature by offering a comparative review of meditation approaches for insomnia and practical advice for how this population may enhance their sleep using meditation.
