The sleep–wake cycle is a process regulated by multiple neurobiological mechanisms that in aberrant functioning provokes several sleep disturbances. Among the major categories of sleep disorders, insomnia represents one of the most reported in population. Pharmacological interventions aimed for treating this sleep disturbance include compounds such as antidepressants, antihistamines, sedative-hypnotics, among others. However, using pharmacological treatments increase undesirable side effects such as addiction to sleep-inducing drugs. Here, we review and summarize recent publications available in PubMed regarding the use of non-pharmacological/invasive means to control insomnia, including physical exercise and transcranial direct current stimulation (tDCS). Current data suggest that these two strategies efficiently manage insomnia, and in turn opens new approaches to develop therapeutical tools to diminish this pathology. Nevertheless, additional research is required to understand the neurobiological mechanism of action of physical exercise and tDCS in insomnia control.
