If you are making an effort to be as healthy as possible, one of the most important things you can do is get enough rest. There are a number of functions that our bodies perform during sleep to repair and refresh our physical bodies - and our mental wellbeing. Not getting an appropriate amount of rest can increase the risk of various conditions, including diabetes, heart disease, obesity, high blood pressure, and stroke. Despite the importance of rest for our bodies, studies suggest that 19% of adults in the United States are not getting enough sleep regularly!

If you feel you are not getting enough sleep, you could speak to your pharmacy in Knoxville, TN, about over-the-counter sleep aids. They may also be able to give you some tips on how to get a better quality of sleep. However, what happens when you feel as though you are sleeping well at night, but you just can’t shake those feelings of fatigue and sleepiness? Let’s investigate what could be causing this and suggest ways to combat them.

Sleep Apnea

One of the most common reasons for fatigue and excessive sleepiness in people who say they are sleeping enough at night is sleep apnea. This condition will briefly stop your breathing during the night, startling you awake. This may happen multiple times per hour depending on the severity of the condition, but because the interruptions last only a few seconds, you may never even realize you have woken up. Even though you appear to have had a total of 8 hours, you are sleep deprived as you never get deep sleep. It is often a partner who notices sleep apnea symptoms rather than the patient as it can cause choking or snoring. Sleep apnea is diagnosed by a doctor following a sleep study and may require the use of a CPAP device to keep airways open while you sleep. However, you can also take proactive steps such as losing weight or giving up smoking to help improve the condition. Your pharmacy in Knoxville, TN, can offer advice on giving up smoking.

Low Blood Sugar

It isn’t just overeating that can be bad for your health. If you do not eat enough, your body doesn’t have enough fuel to function correctly, and you end up fatigued. This can also happen when overeating the wrong types of foods. When your blood sugar drops, that is when you become tired and sluggish. The easiest way to combat this is to follow a balanced diet that includes protein and complex carbs at every meal. It is also best to eat several small meals and snacks throughout the day. Your local pharmacy in Knoxville, TN, can also provide vitamins and supplements to ensure you have the right balance of nutrients your body needs.


Another leading cause of fatigue, especially in women, is anemia. A lack of red blood cells can cause iron deficiency and have a negative impact on the amount of oxygen being carried to your tissues and organs. Women are especially prone to anemia if they suffer from heavy menstrual blood loss. Adding iron-rich foods like lean meats, shellfish, beans, and enriched cereals will help to combat an iron deficiency. Alternatively, iron supplements are available over the counter at your pharmacy in Knoxville, TN.

Excessive Caffeine Consumption

It is well known that caffeine can help to improve alertness and concentration, so if you are suffering from fatigue, you may be using coffee and energy drinks to try and give you a boost. However, it could actually be the caffeine causing the problem in the first place! Excessive caffeine use increases your heart rate, elevates blood pressure, and causes jitteriness. It can also result in fatigue in many people. Suppose this sounds like a problem you might be experiencing. It is important not to stop caffeine intake immediately, resulting in withdrawal symptoms and even greater fatigue levels. It is better to gradually cut down on snacks and beverages that contain caffeine over time. This might include coffee, tea, soda, energy drinks, and chocolate.


Fatigue can also be an indication that your body is dehydrated. It doesn’t matter whether you are working a desk job or carrying out manual labor. You must drink water regularly throughout the day to keep cool and hydrated. Don’t wait until you feel thirsty to take a drink. Your body is already dehydrated if you are thirsty! Sip from your water bottle throughout the day and try drinking two glasses of water before and after a workout or strenuous task. If you are struggling to drink enough to keep you hydrated, ask your pharmacy in Knoxville, TN, about rehydration products and water additives to help.

These are just a handful of the reasons why you could be suffering from fatigue or sleepiness even after a whole night of sleep. If you struggle to get to the bottom of the problem, it is wise to seek medical advice.
