Actionable Insights

1. Aim for Optimal Sleep Duration

Target 7 to 8.5 hours of sleep per night, as population studies show increased all-cause mortality and cardiovascular disease for those consistently sleeping less than 7 or more than 8.5 hours.

2. Prioritize Non-Drug Insomnia Treatment

For insomnia, the gold standard treatment is Cognitive Behavioral Therapy for Insomnia (CBT-I), which helps up to 80% of individuals by addressing psychological factors and rebuilding positive associations between bed and sleep.

3. Avoid Poor Sleep Hygiene Practices

Do not set up a home office in your bedroom, keep the TV on, use electronic devices late, drink a lot of coffee or alcohol in the evening, or have a large carbohydrate-rich meal before bed. These habits disrupt sleep quality and can predispose to chronic insomnia.

4. Create an Optimal Sleep Environment

Ensure your bedroom is dark, quiet, and not too hot or too cold. Using a sleep mask can be very helpful, especially if you don’t have blackout curtains, as light exposure at night can negatively impact sleep quality and increase health risks.

5. Manage Blue Light Exposure

While direct blue light from devices may not immediately cause insomnia, regular late-night use can delay your circadian clock, leading to later bedtimes and potential sleep deprivation if you have fixed morning commitments.

6. Understand Sleep Trackers’ Nuance

If you are already anxious about your sleep, avoid sleep trackers as they can increase anxiety and provide inaccurate data on sleep stages. However, if you are sleep-deprived due to lifestyle choices, a tracker might help you correlate behaviors (like alcohol intake) with sleep quality and motivate positive changes.

7. Recognize Normal Nighttime Awakenings

It is normal to wake up in the middle of the night for up to about 30 minutes over the course of the night; this in itself is not a marker of pathological sleep.

8. Be Aware of Sleep’s Impact on Diet

Even a single night of sleep deprivation can dramatically increase calorie intake and the likelihood of reaching for high-sugar, unhealthy foods, due to changes in appetite-regulating hormones and glucose tolerance.

9. Question Melatonin Supplement Use

While generally safe, consider why you are taking melatonin and if non-drug methods could fix your sleep. There’s a risk of psychological reliance, where the presence of the tablet becomes as important as its biological effect.

10. Consider Magnesium for Restless Legs

Magnesium can anecdotally help some individuals with restless leg syndrome, a neurological disorder causing an urge to move legs, especially at night, which can disrupt sleep.

11. Cultivate a Positive Sleep Identity

Your belief about your relationship with sleep (e.g., ‘I’m a bad sleeper’) can become a self-fulfilling prophecy, influencing both conscious and unconscious factors that give rise to sleep. A positive sleep identity can make sleep easier.

12. Embrace Patience for Insomnia Recovery

Insomnia treatment often requires patience and a multi-pronged approach, as rapid or instant answers are rarely effective. Focusing on long-term solutions, rather than quick fixes, is crucial for lasting improvement.
