When people hear the word “hygiene,” they often think of cleanliness—brushing teeth, showering, or washing hands. However, hygiene extends beyond personal cleanliness and applies to sleep as well. Sleep hygiene refers to the habits and environmental factors that influence sleep quality. Good sleep hygiene can help improve overall health, cognitive function, and emotional well-being, while poor sleep hygiene can lead to fatigue, mood disturbances, and long-term health issues.

The Importance of Quality Sleep
Many people struggle to get sufficient and restful sleep. According to the Centers for Disease Control and Prevention (CDC), adults should aim for 7-9 hours of sleep per night to support optimal health. Poor sleep is linked to increased risks of heart disease, obesity, diabetes, and mental health disorders.
Dr. Rohin Saroya, a Family Medicine Physician at Bayhealth Primary Care, Smyrna, shares essential guidelines for improving sleep hygiene and getting the much-needed rest your body requires.
How to Improve Sleep Hygiene
1. Develop a Consistent Nighttime Routine
A well-established bedtime routine signals the body that it is time to wind down. Start your nighttime routine at the same time every night and follow a series of relaxing activities before bed. Consider the following:
- Avoid screens at least 30 minutes before bedtime – Blue light from phones, tablets, and TVs can suppress melatonin production, making it harder to fall asleep.
- Engage in relaxing activities – Try light stretching, deep breathing, or reading a book.
- Maintain personal hygiene – Brushing your teeth or washing your face before bed can serve as a cue that it’s time for sleep.
- Limit stimulating conversations – Avoid engaging in stressful discussions before bed, as they can keep your mind active.
2. Maintain a Regular Sleep Schedule
Going to bed and waking up at the same time every day—even on weekends—helps regulate your body’s internal clock (circadian rhythm). This consistency can make it easier to fall asleep and wake up feeling refreshed. If you need to change your sleep schedule, adjust it gradually in small increments over several days.
3. Adopt Healthy Daytime Habits
Your daytime activities significantly impact your sleep quality. Here are some habits that contribute to better sleep:
- Use your bed only for sleep – Avoid working, eating, or watching TV in bed to strengthen the mental association between your bed and rest.
- Monitor caffeine intake – Avoid caffeine consumption in the late afternoon and evening as it can interfere with sleep.
- Limit alcohol consumption – While alcohol might make you feel drowsy, it can disrupt sleep cycles, leading to poor sleep quality.
- Take short naps – If needed, limit naps to 20-30 minutes to prevent nighttime sleep disturbances.
- Get daily exercise – Engaging in at least 15-30 minutes of physical activity can help you fall asleep faster and enjoy deeper sleep.
4. Optimize Your Sleep Environment
Creating a sleep-friendly environment is crucial for quality rest. Consider making these adjustments to your bedroom:
- Control light exposure – Use blackout curtains or wear an eye mask to block out unwanted light.
- Reduce noise distractions – Consider using earplugs or a white noise machine to drown out disruptive sounds.
- Maintain a comfortable temperature – Keep your bedroom cool, ideally between 60-67°F (15-19°C), to enhance sleep comfort.
- Invest in a quality mattress and pillows – A supportive mattress and comfortable pillows can reduce body pain and improve sleep posture.
When to Seek Medical Advice
While improving sleep hygiene can help most people get better rest, some individuals may struggle with persistent sleep issues. If you experience excessive daytime sleepiness, difficulty falling or staying asleep, loud snoring, or frequent awakenings, you may have an underlying sleep disorder such as insomnia, sleep apnea, or restless leg syndrome. Consult a doctor for proper diagnosis and treatment.
