Updated:April 23, 2026

If You’re Not Waking Up Feeling Refreshed, an Underlying Health Issue May Be to Blame. If It’s Related to Your Adrenals, Adrenal Fatigue Treatment in Kennesaw, GA, May Be the Solution.
Sleep is supposed to be recharging. You might be a little groggy when you first wake up, but that feeling will dissipate after you give yourself some time to get your wits about you. However, if you’re feeling tired throughout the day, even after getting the recommended amount of sleep, it might be that your adrenals are not functioning properly anymore.
Adrenal fatigue treatment in Kennesaw, GA, can help. Other causes could be at work as well.
Achieve better energy throughout the day when you get to the source of your fatigue.
1. Poor Sleep Quality
Even if you’re getting the suggested seven hours or more of sleep each night, that doesn’t mean the whole thing was quality. Your body goes through a sleep cycle, typically four to six times each night.
The Stages
It starts with light sleep that lasts for about five to 10 minutes. This is when your body is getting into relaxation mode. Your breathing and heart rate will slow. During this time, it’s easy for someone to wake you.
You then go into stage II, which is also a light sleep, and this tends to make up around half of your sleep each night. Your brain activity slows, but it still has spurts of activity. Moreover, your breathing and heart rate will steady while your body temperature drops.
Stage III is when you go into a deep sleep. It’s difficult to wake you during this time, but it’s when your body is working hard to repair muscle tissue damage, strengthen your immune system, and release growth hormone. When you feel groggy when you wake up, it’s usually because you woke up during this phase.
In stage IV of your sleep cycle, you’re in REM sleep, also known as rapid eye movement. It usually happens 90 minutes after you fall asleep. Dreaming usually occurs in this phase. Your brain activity during this time is similar to when you’re awake. Emotional regulation and memory processing tend to happen during this time. Your first REM cycle is usually the shortest and will progressively get longer throughout the night. REM sleep makes up about 25 percent of your total night’s sleep.
Typically, you go into stage II, stage III, stage II again, and then REM. The pattern then repeats. Sometimes, you may enter stage I throughout the night, but that doesn’t happen to everyone.
What Poor Quality Sleep Means
Whenever you aren’t going through these stages as you should, you may not get quality sleep. You merely get the recommended number of hours of sleep. As a result, the next day, you may feel tired and worn out.
Interestingly enough, you may not know you’re getting poor sleep quality. You’ll just feel it throughout the next day. When you go to bed at night, you may either fall asleep incredibly quickly or have trouble staying awake.
2. Bad Sleep Habits
Having bad sleep habits often goes along with receiving a poor quality sleep. Your body may not go into the cycles as it should whenever you’re drinking alcohol or caffeine before bed, are stressed or anxious frequently, or use electronic devices before bed.
Your sleep cycles may be thrown off if you don’t have a usual bedtime routine. While not going to bed at the same time on the dot each night won’t harm your sleep schedule, not having any round-about time for bed could do more harm than good, and you might find yourself getting a poor quality of sleep many nights.
3. Dehydration
Water makes up between 50 and 70 percent of your total weight. It’s necessary for many functions in the body, such as digestion, temperature regulation, brain function, and shock absorption for the spine.
When you’re not getting enough fluid regularly, and don’t forget you need electrolytes to balance the liquid for your body, you may feel tired throughout the day because the following may happen:
Your heart starts to work harder.
You receive fewer nutrients and less oxygen to the brain.
You have poor energy production from an electrolyte imbalance.
Your body may use more energy to compensate.
4. Hormonal Changes
As you age, you don’t have any say-so in it, but your hormones start to decline. For men, the transition happens slowly, with about a 1 to 2 percent decrease each year.
For women, progesterone tends to drop first, with estrogen levels fluctuating until they decrease tremendously during menopause. Perimenopause, which is when symptoms tend to happen the most, usually lasts four to eight years. Then, you’ll reach menopause, which occurs when you have an absence of periods for 12 consecutive months. You may still have symptoms then as well.
One symptom that could occur for either women or men during this transition is sleep disturbances. You may have trouble falling asleep, will wake up during the night, could have hot flashes/night sweats, or might have anxiety that induces insomnia.
5. Adrenal Fatigue
Your adrenal glands produce stress hormones. However, when you’re putting your body into a high-stress state over minor matters, such as poor eating or sleeping habits, you’re causing your body to release more of these stress hormones than needed.
This can wreak havoc throughout the body. The glands might no longer produce hormones like normal, which can leave you feeling tired when your body isn’t releasing its morning dose of cortisol.
Your sleep cycle might not be what it used to be. And your blood sugar levels may spike and rapidly drop, leaving you feeling tired when they’re low. When so much is going wrong in the body, you may feel tired because your body just isn’t recovering.
