Tired After 8 Hours Sleep? Here’s What To Do

You turned down your friends for a well-deserved night out. Ticked all boxes on your to-do checklist proactively. Went to bed before traffic vanished from the roads. All in the hope of waking up fresh and enthusiastic the next morning.

Yet, you feel tired even after 8 hours of sleep. You don’t want to get out of bed and start the day. Snoozing your alarm thrice, you yell inside your aching head:


You’re not alone.

Google shows “sleep" searches went higher than ever in 2023, reflecting a growing number of sleep disorders, especially among Gen Z. It’s clear that a lot of people are wondering why they wake up tired with no energy.

A quality shut-eye sleep is a must for the healthy functioning of body and mind. In this article, we’ll try to understand why you feel tired even after 8 hours of sleep and will offer you innovative solutions.

Why Is Quality Sleep Important?

Trapped in the hustle and bustle of a fast-paced life, your body and mind need a recharge.

Quality sleep offers you a ton of benefits that can help you maintain optimal health and overall well-being.

Physical Health

During a sound sleep, your body releases cytokines. These proteins fight infections and inflammation, boosting your immune system and protecting you from diseases.

Quality sleep also regulates your hormones like insulin and cortisol, helping metabolism, weight management and blood sugar control.

Also, while you’re asleep, your body repairs itself from inside — rebuilding tissues and cells.

Mental Health

Sleep sharpens your focus and boosts your memory, making it easier for you to learn and retain new information.

The phrase “waking up on the wrong side of bed” isn’t a casual excuse. Sleep plays a pivotal role in improving your mood and reducing your stress.

Also, deep sleep triggers creativity and offers clarity for problem-solving. A well-rested person has better reaction time, judgment, endurance, and coordination than someone who’s sleep-deprived.

How Much Sleep Do You Need?

“Why am I so tired after sleeping for 8 hours straight? Do I need to sleep for 8 more? What’s the right number? How much sleep do I need?! I’m going crazy right now…”Questions like these show up in our inbox every day.  

Every human is different in terms of age, lifestyle, and overall health. The amount of sleep a person needs varies across different life stages.

Here’s a comprehensive table of sleep recommendations for different age groups:

Healthy sleeping patterns and aiming for the recommended hours based on your age group are essential for maintaining your overall mental and physical well-being.

Why Do You Wake Up Tired After 8 Hours Of Sleep?

8 hours sounds like a golden number that could guarantee you a fresh start. But if that were the case, you wouldn’t be reading this blog, would you?

You’re dutifully logging these eight hours, only to greet the morning with a yawn and a heavy head.

Let’s understand the common reasons behind why you feel tired even after 8 hours of sleep.

Sleep Disorders

Your morning fatigue could be the result of a sleep disorder. These conditions disrupt your sleeping patterns. As a result, you might feel like you’re sleeping for a good amount of time, but your body is not getting the restorative rest it needs.

Some of the most common sleep disorders include:

  • Sleep Apnoea: Your breathing repeatedly starts and stops during your sleep.
  • Insomnia: You find it difficult to fall or stay asleep for long.
  • Restless Legs Syndrome: You wake up due to an irresistible urge to move your legs.

There are many more, and these sleep disorders must be tackled head-on to ensure your sleeping patterns get back to normal.

Diet and Lifestyle Factors

“What you put in your body shows in what you do” — isn’t that what they all say?

It’s true that your diet and overall lifestyle impact your sleep.

If you’re living on an unhealthy diet, you will feel the weight of it under your eyelids, even after sleeping for 8 hours straight.

  • Caffeine and Alcohol Consumption: Caffeine or other such substances can make you feel drowsy, so you won’t wake up fresh even after a long rest.
  • Unhealthy Food: Consuming processed foods, sugary drinks, and junk food disrupts your digestive system and ruins your sleep.
  • No Physical Activity: Without exercise, you won’t get quality shut-eye. You’ll feel fatigued even after a solid nap.
  • Irregular Sleep Schedule: Your body's natural sleep-wake cycle is disrupted when you go to bed at irregular and inconsistent times.

You must adjust your diet and lifestyle to get high-quality sleep. That’s the only way to retain your vitality and strength in the long run.

Sleep Quality

It doesn’t really matter how long you doze off for. It’s more about the quality of sleep. This will dictate how you feel when you wake up.

Many factors can diminish your sleep quality. Some are:

  • Noise: Ensure that there are no loud or disruptive noises where you sleep — it’s critical for your sleep quality.
  • Light: Don’t expose yourself to bright light, especially before you doze off, as it can suppress the production of melatonin — a hormone that helps regulate sleep.
  • Temperature: Don’t sleep at an excessively hot or cold place. Quality sleep comes from comfort.
  • Stress and anxiety: Overthinking before going to bed or suffering from mental and emotional stress can make it harder for your thoughts to go silent and let you sleep.

Your sleep quality is just as important as the time you spend in your bed.


Your body needs certain nutrients to regulate your ability to doze off and sleep soundly. For example:

  • Iron: Your body needs iron to carry oxygen throughout. Without it, your body will suffer from fatigue and weakness.
  • Magnesium: Magnesium helps your muscles relax and make you comfortable falling and staying asleep.
  • Vitamin D: A Vitamin D deficiency can cause sleep issues and a feeling of tiredness when you wake up.

Ensure your body doesn’t suffer from any deficiencies to avoid waking up tired and restless.


Suffering from stress can make it very hard for you to fall and stay asleep in the long run. Moreover, even if you manage to get a good 8 hours off the clock, you won’t feel rejuvenated.

It’s important to maintain your stress levels to improve the quality of your sleep. You can do that by:

  • Practicing relaxation techniques
  • Engaging in regular exercise
  • Seeking professional help
  • Developing healthy coping mechanisms
  • Avoiding stressful activities before bed


Anxiety keeps you up at night. You might find it difficult to get a hold of the Sandman and doze off to a peaceful sleep.

Sleep is good for your anxiety, as it helps restore your mental energy while offering you an escape.

But if your mind is constantly awake, worrying about the day's events, you may not get enough sleep or have trouble sleeping soundly.

Anxiety is something that should be addressed to enable a healthy sleeping routine. It’s necessary for your physical and emotional well-being.

Screen Time

The time you spend researching holidays, scrolling your social media, or playing with your friends on your tablets or gaming consoles affects your sleep more than you probably imagine.

The blue light emitted from electronic devices like smartphones, tablets, and laptops can suppress melatonin production.

Elongated and irregulated screen times can affect your sleeping patterns, especially before bed.

You should:

  • Avoid using electronic devices in bed. Instead, read a book or listen to deep sleep, relaxing music or a podcast — anything that doesn’t need a screen.
  • Turn off screens at least an hour before bedtime. Your body will have more time to produce melatonin and prepare for sleep.
  • Use blue light filters on your devices. Some devices come with built-in blue light filters, and some apps can do the same.

Your Sleep Environment

Your bedroom or sleep environment affects your sleep quality significantly.

To get the most out of your 8-hour adventure, you should ensure your bedroom is:

  • Dark: This can be done with blackout curtains or an eye mask to block out any light.
  • Quiet: Get earplugs or a white noise machine if you live in a noisy area.
  • Cool: Maintain room temperature between 60-67 degrees Fahrenheit.
  • Comfortable: Ensure that your mattress and pillows are ergonomic and comfortable.

  • White Noise Machines and Sleep Apps: White noise machines block out distractions and create a calming sleep environment. Apps with nature sounds, guided meditations, and sleep stories can also help you relax.
  • Smart Beds and Pillows: You can adjust the temperature, firmness and position of your sleeping companions to enhance your comfort and sleep quality.
  • Nap Pods: Designed for quick power naps, these compact, soundproof booths provide a space to relax during the day.

Frequently Asked Questions

Why am I still tired after getting good sleep?

Lack of exercise, dehydration, mental health struggles or even hormonal imbalances can steal your energy and make you feel tired after getting a good sleep. 

Why do I never wake up feeling refreshed?

Sleep disorders, poor sleep hygiene, chronic stress, or even an underlying health condition could be the reason why you’re not feeling refreshed. 

Why am I always tired even though I get enough sleep?

Nutrient deficiencies, chronic stress, hidden health issues or your diet may be the reason behind your tiredness and post-sleep exhaustion.
