Sleep is one of the most vital pillars of health, yet its impact on your daily functioning and emotional health is often overlooked. So, what is sleep hygiene?
Sleep hygiene refers to the environmental factors and behaviors that influence how well you sleep. While you sleep, your body and brain undergo critical processes to recharge and restore on a cellular level, and research has shown that people with healthy sleep habits are more likely to experience happiness and an overall increase in life satisfaction.
Poor sleep, on the other hand, can result in lower mood and can cause spikes in stress and anxiety levels, along with disruptions to your hormones, immune system, energy levels, and ability to maintain a healthy weight. There is also evidence linking sleep deprivation to heightened emotional reactivity and impaired cognitive performance.
How You Can Improve Your Sleep Hygiene
One key factor in improving sleep hygiene is becoming mindful of your natural circadian rhythm. Your circadian rhythm is your body’s internal 24-hour clock, which varies from person to person. This is where “night owls” and “early birds” come into play. This rhythm signals when it is time to wake and when it is time to sleep.
Your circadian rhythm may be misaligned if you have trouble waking or falling asleep at consistent times, fluctuating energy levels, or persistent daytime drowsiness. To better align with your natural rhythm, track your sleep over 1–2 weeks using a sleep journal or a sleep tracking app that suits your preferences. Be sure to log your sleep duration, wake-up times, and bedtimes. Additionally, engaging in regular physical activity and increasing your exposure to natural sunlight are crucial for boosting melatonin production—your body’s sleep hormone. (Tip: Adults between the ages of 18–64 should aim for 7–9 hours of sleep each night.)
Other factors essential to sleep hygiene include keeping a consistent sleep schedule, limiting screen time in the evening, avoiding caffeine and alcohol before bed, and incorporating relaxing activities or hobbies to wind down. Although limiting screen time is generally advised, some people find comfort in watching calming shows or videos before sleep. You can also experiment with your bedroom environment: adding a sound machine, using dim lighting, or adjusting the room temperature may enhance your sleep quality. Incorporating gentle yoga or stretching can also promote relaxation and improve sleep.
Understanding and improving your sleep can lead to better mood, sharper focus, and a stronger immune system, and prioritizing sleep hygiene isn’t about perfection—it’s about consistency and self-awareness. By tuning into your body’s natural rhythms and creating a sleep-friendly environment, you set the stage for deeper, more restorative rest. Whether it’s adjusting your bedtime routine or tracking your sleep patterns, the most important aspect of achieving optimal sleep hygiene is discovering what works best for you and committing yourself to those habits consistently. Better sleep starts with better habits—and it’s never too late to begin.
