“In 2020, 14.5% of adults had trouble falling asleep most days or every day in the past 30 days,” according to data from the CDC’s Sleep Difficulties in Adults: United States, 2020 National Health Interview Survey.

Trouble falling asleep can lead to insomnia, affecting concentration, emotional well-being, academic performance, and overall quality of life. To help prevent these issues, a study examined the effects of an email-delivered cognitive behavioral therapy for insomnia in college students.

According to their findings, “The intervention group demonstrated significant improvement in attitudes toward sleep, sleep quality, sleep hygiene, and daytime sleepiness from pretest to posttest. Furthermore, the intervention group showed more positive outcomes compared to the comparison group at the posttest.”

 

How email-delivered CBT can support insomnia treatment

CBT-I is a structured, evidence-based approach to treating insomnia. “Cognitive behavioral therapy for insomnia (CBT-I) is the first-line treatment for insomnia. It’s structured therapy that involves changing your sleep routine and habits. CBT-I can lead to a long-lasting improvement in your symptoms,” Cleveland Clinic’s webpage on CBT-I explains. Depending on the treatment plan, interventions may incorporate sleep education, stimulus control, relaxation techniques, cognitive restructuring, and guidance on sleep scheduling.

In the above-mentioned study, participants in the intervention group received six weekly CBT-I sessions via email, while the comparison group received a link to a student wellness website containing healthy sleep information. The researchers concluded that “An email-delivered sleep intervention is a feasible and easy-to-use tool that nurses can utilize to promote sleep quality among college students.”

These findings suggest that email can support structured sleep interventions. More specifically, it shows how healthcare providers can use emails to support patients with insomnia. In the U.S., HIPAA law mandates that emails containing protected health information (PHI) must be safeguarded during transmission and at rest.

 

How HIPAA compliant email supports patient communication

HIPAA compliant email solutions, like Paubox, use advanced encryption, audit trails, and access controls, so providers can securely send a patient sleep hygiene recommendations or instructions for completing a sleep diary. Patients can then reply at their own pace, with information about their symptoms and treatment programs.

 

Improving sleep education

Providers can use HIPAA compliant emails to send educational materials that explain the link between sleep habits and insomnia. More specifically, providers can include a structured series of messages that introduce topics progressively, so patients can apply their recommendations over time.

For example, a six-week program could provide weekly educational content and exercises. In the first few weeks, providers can introduce foundational sleep hygiene and environment audits. Towards the end of the program, providers can introduce cognitive restructuring to reframe sleep-related fears and conclude with relapse prevention plans.

Ultimately, CBT-I helps patients understand “how sleep pressure and [their] body’s internal clock work together, why certain habits and behaviors interfere with sleep, [and] the purpose behind treatment recommendations,” Cleveland Clinic explains.

 

Supporting sleep diaries and behavioral exercises

HIPAA compliant emails allow providers to share sleep diary templates, so they can identify patterns in the patient’s sleep timing and daytime functioning. Providers can also use secure emails to reinforce behavioral exercises between appointments, supplementing clinical assessment.

For example, a provider can send reminders encouraging patients to maintain personalized sleep schedules and practice relaxation techniques. Patients can then document their experiences and share updates with their providers. This information can help clinicians evaluate treatment progress and even identify possible barriers to adherence, like if the patient experiences late-night anxiety.

 

Reinforcing treatment adherence

Receiving regular HIPAA compliant emails can remind patients to complete assigned exercises or prepare questions for their next appointment. Providers can securely send their patients a list of things they can do to help maintain consistency, like “setting an alarm for wakeup, scheduling morning activities with other people to help motivate [them] to get out of bed, especially on weekends, [and] staying active in the hours leading up to [their] prescribed bedtime so [they] don’t fall asleep too early,” as Cleveland Clinic suggests.

 

Incorporating stimulus control techniques

According to Cleveland Clinic, stimulus control is a major component of CBT-I, where patients pair “sleep-related things — like [their] bed and darkness — with sleep. [They] avoid things associated with being awake — like screen time or reading — in [their] bedroom. It helps patients develop stronger associations between their sleeping environment and rest while reducing habits that can interfere with sleep.

Healthcare providers can use secure email to explain these principles and help patients understand how consistent routines support insomnia treatment. For example, providers can send reminders encouraging patients to go to bed only when sleepy and avoid daytime naps when recommended as part of their treatment plan. Educational messages can also explain the recommendation “getting out of bed if you can’t fall asleep within 15 to 20 minutes.”

 

Extending access to sleep education

As the above-mentioned study suggests, email-delivered interventions can be useful for college students and other patients who must balance their insomnia treatment with academic, work, or personal responsibilities. HIPAA compliant email solutions, like Paubox, can be personalized to accommodate the patient’s specific needs, like their preferred language, digital literacy, and whether they need additional accessibility features such as larger font options.

Providers can also collect these patient preferences using a HIPAA compliant form. This is a secure form that allows providers to gather the patient’s personal information so they can submit their preferences securely. For example, a provider can ask their patient to indicate their preferred language of communication and then use their answer to inform their CBT-I email-based intervention.

 

Supporting sleep restriction therapy

Sleep restriction therapy (SRT), also known as sleep consolidation, is a component of CBT-I that aligns the time spent in bed with the amount of sleep the patient gets. People experiencing insomnia may try to compensate for poor sleep by going to bed earlier or taking daytime naps. However, these behaviors can contribute to a mismatch between sleep opportunity and actual sleep, Cleveland Clinic suggests.

Providers can use HIPAA compliant emails to help patients understand SRT and why they recommend temporarily adjusting their time in bed. Since sleep restriction can initially increase daytime tiredness, providers must keep a close eye on their patients to monitor changes to their sleep schedules.

Secure emails can help providers check in with patients about treatment progress, communicate adjustments, and address possible questions. These emails can help healthcare providers identify difficulties with adherence or determine when additional support, like counselling, is needed.

Furthermore, these emails can help providers keep in touch with their patients, supporting continuity of care, especially since insomnia is commonly associated with comorbid conditions, like depression, post-traumatic stress disorder (PTSD), and obstructive sleep apnea. These comorbidities may complicate treatment and require coordination between multiple providers. Patients can also use these emails to raise concerns about persistent sleep difficulties. This way, providers can identify when further assessment or referrals to other specialists are needed.

 

Coordinating insomnia care

Secure emails can further support insomnia care coordination among providers, like nurses, therapists, and other clinicians involved in the patient's care. These providers can use HIPAA compliant emails to share sleep diary templates, communicate personalized sleep schedules, and provide feedback on patients’ progress. Sleep diaries help them understand the patients’ sleep patterns and make the required treatment adjustments.

For example, if a therapist notices that a student is struggling to complete the sleep diary, they might consult with their primary care physician to find out if the student has any underlying issues like attention deficit hyperactivity disorder (ADHD), which is impacting their ability to complete the diary.

The primary care physician can respond with relevant research articles or resources that could benefit the student. Furthermore, the therapist can create a shared digital folder accessible via secure email, containing sleep diary templates, educational materials about ADHD, and tips for parents on how to support their child.

When the student begins to implement the new strategies, the therapist can regularly check in via HIPAA compliant email to monitor progress. They might ask the primary care physician to provide updates on any medication adjustments or behavioral strategies being used, so CBT-I is as effective as possible.
