Sleep Hygiene and Mental Health Resources

Sleep hygiene refers to the practices and habits necessary for achieving high-quality sleep at night and maintaining full alertness during the day. Good sleep health is built on understanding a few basic terms:

• Circadian Rhythm: This is your internal biological clock. It operates on a roughly 24-hour cycle, controlling when you feel sleepy and when you feel awake. Your rhythm can be easily disrupted by late nights or too much artificial light.
• Sleep Debt: This is the cumulative deficit built up when you consistently lose sleep over several days. You owe your body the time you missed, and that debt can negatively affect your concentration and mood.
• Sleep Deprivation: This refers to a consistent or complete lack of sleep, resulting in extreme fatigue, impaired coordination, and difficulty concentrating.
• Sleep Disorder: This is a category of clinical diagnoses including conditions that cause persistent sleep disturbances, such as insomnia, sleep apnea, or restless leg syndrome.

Adolescents typically need eight to 10 hours of uninterrupted sleep each night for optimal health and brain development. However, the quality of that sleep is based on more than just the number of hours you spend resting. Your body, your room, and your daily schedule all play significant roles in how well you sleep.

Environment

Your sleep environment includes external factors that can directly disrupt your body's natural sleep cycle.

• Light: Your circadian rhythm is sensitive to light. Exposure to natural sunlight during the day helps regulate it, but too much artificial light close to bedtime, especially from electronics, confuses your brain into thinking it should stay awake.
• Temperature and Noise: Extreme temperatures or humidity can interfere with your body's internal temperature regulation, making it difficult to fall asleep or stay asleep. Shared or loud sleeping spaces can also cause sleep disruptions.

Behavior

The choices you make during the day heavily influence your rest at night.

• Exercise: Regular physical movement helps your body use up energy and can increase natural feelings of tiredness. However, intense exercise too close to bedtime can elevate your heart rate and make it harder to fall asleep.
• Napping: Taking short, strategic naps can be beneficial, but long, sporadic naps throughout the day can disrupt your circadian rhythm, making it more challenging to fall asleep at your regular bedtime.
• Bedtimes: Having a consistent bedtime routine is the best way to help your body listen to its cues of feeling tired, allowing you to regulate the total amount of sleep you get each night more effectively.

Nutrition

Specific types of food and drink can directly affect your sleep.

• Stimulants: Consuming beverages containing caffeine (such as soda, coffee, and energy drinks) or foods high in added sugar late in the day can stimulate your digestive and nervous systems, making it nearly impossible to fall asleep.
• Inflammatory Foods: Foods containing dairy or added sugar can sometimes inflame the digestive system, potentially causing discomfort that leads to frequent nighttime awakenings.

The effects of poor sleep extend far beyond feeling tired or performing poorly at school the next day; they profoundly impact your mental and emotional well-being. Sleep disruptions have been shown to alter brain chemistry, which can significantly raise the risk for or worsen mental health disorders.

The connection between sleep and mental health is bidirectional: Poor sleep hygiene can make symptoms of conditions like anxiety and depression worse, and those conditions often make it harder to sleep.

For people dealing with depression, symptoms like insomnia or excessive sleeping (hypersomnia) often overlap, making the condition more complicated to manage. Additionally, extreme fatigue can make it incredibly difficult to get out of bed in the morning or maintain motivation throughout the day.

Symptoms of anxiety are also frequently made worse by poor sleep habits. A racing mind full of worries is the biggest challenge to falling and staying asleep, often resulting in inconsistent sleep patterns, frequent nightmares, and exhaustion during school hours. Sleep loss may also decrease the brain's ability to control emotional responses, leading to emotional dysregulation.

Anyone can practice better sleep hygiene, but the specific approach needs to fit your individual life and schedule. Experts recommend thinking of your bedtime routine as a "pre-performance routine," similar to warming up before a big game. Establishing healthy habits can help you get the restorative sleep your body needs.

1. Maintain a regular bedtime and wake-up time every day, even on weekends, to reinforce your circadian rhythms.
2. Avoid eating large meals or foods high in added sugar right before bed.
3. Exercise earlier in the day to avoid having an elevated heart rate near bedtime.
4. Refrain from using digital screens, including phones, tablets, and computers, for one to two hours before going to sleep.
5. Use "do not disturb" settings to limit technology disruptions and alerts during sleep hours.
6. Implement screen time limits on digital devices throughout the day to reduce overall use.
7. Seek out natural sunlight early in the day; try sitting near a window or taking a short walk outside.
8. Refrain from consuming caffeinated beverages, including teas and sodas, past the early afternoon.
9. Maintain a calm, dark, and quiet bedroom to optimize your sleep environment.
10. Document your sleep routines, disruptions, and any frequent nightmares in a journal to help identify patterns.

If you are experiencing chronic sleep difficulties, persistent daytime fatigue, or symptoms of a mental health condition, seek guidance from a licensed primary care provider. Addressing sleep issues is a crucial step toward achieving good health, well-being, and academic success.
