Why Am I Always Tired? Sleep Needs in Teens

Mom says I love to sleep?

Hello, Dr.
Chen! I am a middle school student.
I commute to school every day, and during the summer, I have half-day classes.
My mom wakes me up before 5:30 AM.
After having breakfast and getting ready, I leave for school by 6:30 AM to catch the bus.
I usually return home around 1 PM for lunch, but recently, the homework assigned by my teachers has become overwhelming.
My brother suggested that I use the afternoons to study at the city library near the school, as he believes it helps with concentration.
He studied at the library every day while preparing for university exams, and it really improved his results.
My mom also supports this idea, so I have been skipping lunch at home and eating takeout instead.
After eating, I go to the library to do my homework until it closes at 5 PM, and by the time I get home, I feel very tired.
I often need my mom to call me several times before I get up to eat dinner, and after eating, I just want to go back to sleep.
My mom is not happy about this, and my dad suspects that I might be sick and wants me to see a doctor.
I don’t feel sick; I just want to get a good night’s sleep.
Doctor, could you tell me if this phenomenon indicates any illness? Is it normal for someone my age to want to sleep more? I’ve asked several classmates, and they also love to sleep, some even more than I do, yet their moms don’t scold them or suspect them of being sick.
Please provide me with an answer so that my parents can feel reassured.
Thank you.

When a person becomes fatigued, they will naturally feel the urge to sleep in order to recover from that fatigue.
As long as one adheres to their circadian rhythm, there is no need to emphasize a specific number of hours of sleep required each day.
Generally, for your age, sleeping 7-8 hours or more per day is sufficient.
Some cases of hypersomnia may be caused by hypothyroidism, otolaryngological disorders, or central nervous system abnormalities, all of which need to be diagnosed by a physician.
Based on the symptoms you described, it does not seem to resemble hypersomnia.

More Info

Feeling constantly tired, especially as a teenager, is a common concern that can stem from various factors, including lifestyle, sleep patterns, and even underlying health issues. As a middle school student, your daily routine is likely packed with school, homework, and social activities, which can lead to fatigue if not managed properly.

Firstly, it's important to understand that teenagers typically require about 8 to 10 hours of sleep per night for optimal health and functioning. However, many teens struggle to achieve this due to early school start times, homework demands, and social obligations. The fact that you are waking up at 5:30 AM and potentially not getting enough sleep could be a significant contributor to your tiredness. If you are not getting enough restorative sleep, it can lead to feelings of exhaustion, difficulty concentrating, and irritability.

Additionally, the pressure of increased homework and the decision to spend your afternoons at the library can also contribute to your fatigue. While studying in a quiet environment can be beneficial for focus, it’s essential to balance study time with adequate breaks and relaxation. If you are spending long hours studying without sufficient rest, it can lead to mental fatigue, making you feel even more tired when you return home.

Another factor to consider is your diet and hydration. Eating lunch outside and possibly opting for quick meals may not provide the necessary nutrients your body needs to sustain energy levels throughout the day. A balanced diet rich in fruits, vegetables, whole grains, and proteins is crucial for maintaining energy. Staying hydrated is equally important, as dehydration can lead to fatigue.

It's also worth mentioning that emotional and psychological factors can play a role in how you feel. Stress from schoolwork, social pressures, or even changes in your routine can lead to feelings of fatigue. If you find that you are feeling overwhelmed or anxious, it might be beneficial to talk to someone about it, whether it's a parent, teacher, or school counselor.

Regarding your parents' concerns about your health, it’s understandable that they want to ensure you are okay. While your symptoms do not necessarily indicate a serious health issue, it’s always a good idea to consult with a healthcare professional if fatigue persists. They can help rule out any underlying conditions, such as anemia, thyroid issues, or sleep disorders, that could be contributing to your tiredness.

In summary, here are some steps you can take to address your fatigue:
1. Prioritize Sleep: Aim for at least 8 hours of sleep each night. Try to establish a consistent bedtime routine that allows you to wind down before sleep.

2. Manage Your Time: Balance study time with breaks. Consider setting specific times for homework and leisure to avoid burnout.

3. Eat Well: Focus on a balanced diet that includes a variety of nutrients. Try to pack healthy snacks and meals for school.

4. Stay Hydrated: Drink plenty of water throughout the day to maintain energy levels.

5. Talk About It: If you feel overwhelmed, don’t hesitate to reach out to someone you trust for support.

If after making these adjustments you still feel excessively tired, it would be wise to seek medical advice to ensure there are no underlying health issues. Remember, taking care of your physical and mental health is essential, especially during your teenage years.
