Nonpharmacologic interventions include promoting greater sleep quality and quantity by emphasizing good sleep hygiene practices. Developing a practical and effective bedtime routine, creating a quiet sleep environment, and practicing healthy daily habits are essential components to sleep hygiene (TABLE 249,50). Relaxation techniques and cognitive behavioral therapy (CBT) also can help. CBT for insomnia (CBT-I) is the first-line intervention for chronic insomnia.51 Sleep restriction is a type of CBT used to treat insomnia, encouraging short-term sleep loss in the hopes of improving insomnia. A trial by Logue et al showed that patients with overweight and obesity randomized to undergo CBT with better sleep hygiene (nonpharmacologic) interventions had a greater mean weight loss percentage (5% vs 2%; P = .04) than did those who received CBT alone.52

Patient tips for improving sleep pattern

Eastern medicine including herbal interventions lack evidence of efficacy and safety. Further studies need to be done on the effects that chamomile, kava, valerian root (Valeriana officinalis), tryptophan, and Wu Ling (from mycelia Xylaria nigripes) might have on sleep.53

Proceed cautiously with medication. The American College of Physicians recommends a shared decision-making approach when considering pharmacologic therapy for chronic insomnia and the American Academy of Sleep Medicine (AASM) offers guidance on options.51,54 However, the evidence behind AASM sleep pharmacologic recommendations is weak, implying a lesser degree of confidence in the outcome and, therefore, in its appropriateness. Thus, it falls upon the clinician and patient to weigh the benefits and burdens of the pharmacologic treatments of insomnia. If indicated, medications suggested to treat sleep onset and sleep maintenance insomnia are eszopiclone, zolpidem, and temazepam. Zaleplon, triazolam, and ramelteon may improve sleep initiation. Suvorexant and doxepin are used for sleep-maintenance insomnia.54 Exploring patient preferences, cost of treatment, health care options, and available resources should all be considered.
