The reason why I don't feel refreshed even after a good night's sleep is

If you know why you can't relieve your tiredness, the improvement method is surprisingly simple. This is not just because you sleep less, but because minor habits and environments in your daily life build up fatigue.
have poor sleep
Even if you sleep for a long time, if you don't get a deep sleep, your fatigue will not be relieved. Smartphone use, late caffeine intake, and irregular bedtimes interfere with deep sleep and reduce coolness.
Reduce blue light exposure an hour or two before bedtime, and keep your bedroom dark and quiet. Regular bedtime and comfortable bedding help you sleep well. Relaxing the body with a cup of warm tea or light stretching before bed improves sleep quality.
an ill-advised diet
Late dinner, frequent drinking, and sugary drink intake overactivate the digestive system and interfere with the quality of sleep. In addition, sugar or refined carbohydrates-oriented meals lead to a surge in blood sugar, resulting in fatigue. As a result, poor eating habits also reduce the quality of sleep, making it difficult for the body to recover properly. Regular mealtime stabilizes the body's rhythm.
a lack of moisture
Lack of water in the body easily causes fatigue. If you don't drink enough water, your brain and muscles can be difficult to function properly, which can lead to a state of lethargy. The habit of sharing enough water not only improves sleep quality but is also fundamental to health. Putting water bottles in a prominent place and making a habit of drinking them frequently reduces fatigue.
breathing problems
If you have snoring or sleep apnea while sleeping, it is difficult to sleep well due to lack of oxygen supply. If you're tired or have a headache in the morning, let's doubt it. It is recommended to be diagnosed and corrected at an otolaryngology or sleep clinic. If you solve the breathing problem, you feel much fresher in the morning.
lack of exercise
Lack of exercise lowers blood circulation, which hinders the supply of oxygen and nutrients. This causes muscle fatigue and lethargy, and also reduces brain concentration.
At least three times a week, light walking or stretching for about 30 minutes will lighten your body. Aerobic exercise provides oxygen to the brain and helps relieve fatigue. If you don't have enough time, micro-exercise (climbing stairs, stretching) for 5-10 minutes in the middle of work is also effective. Exercise releases endorphins to refresh the mood and reduce fatigue.
chronic stress
Chronic stress causes the brain and body to get tired by over-releasing cortisol hormones. Worry and anxiety reduce sleep quality and increase morning fatigue. Let's calm our minds with 5 to 10 minutes of meditation, deep breathing, or a light walk a day. It is also effective to reduce the burden on your head by organizing what to do with a memo. Stress management is essential for reducing fatigue and maintaining a clear mind.
nutrient imbalance
Lack interferes with energy generation, causing fatigue. In particular, a lack of iron leads to anemia, adding to lethargy. Let's balance nutrition by including nutrient-rich foods in our diet. Take nutritional supplements if necessary, but it is safe to take them after consultation with a doctor. A balanced diet keeps the body's energy stable to reduce fatigue.
No matter how much I sleep, the reason why I'm tired is not simply 'I didn't get enough sleep'. The quality of sleep, water intake, eating habits, exercise, stress, lack of nutrients, and health problems should be carefully checked. Just changing small habits can bring back energy and change the condition of the day.
