Getting enough sleep is essential for overall health. Unfortunately, many of us don’t get enough, which may lead to fatigue.

Deficiencies

Poor diet
Your diet significantly affects the way you feel.
To maintain energy and get the nutrients your body needs to perform critical processes, it’s important to consume a balanced diet high in nutrient-dense foods.
When you don’t obtain enough calories and nutrients like protein, your body breaks down fat and muscle to meet energy demands. This leads to losing body fat and muscle mass, which may triggerTrusted Source fatigue.
Additionally, diets high in ultra-processed foods impair energy levels. For example, a diet high in added sugar may harm sleep and lead to chronically high blood sugar and insulin levels, resulting in fatigue.
Following a diet low in ultra-processed food and added sugar but rich in nutrient-dense foods like fruits, veggies, legumes, and healthy protein sources may help reduce fatigue and support healthy sleep while providing your body with optimal nutrition.
Consuming too much caffeine
Although caffeinated beverages like coffee and energy drinks feel like they boost energy, over-reliance on them may make you more tired the next day. That’s because too much caffeine can harm sleep, which may cause fatigue.
Research shows that feeling tired in the morning leads people to consume large amounts of caffeine, which impairs their sleep cycle. In turn, you may overuse coffee or other caffeinated drinks for energy, which continues the cycle of poor sleepTrusted Source followed by too much caffeine.
While coffee and caffeinated beverages like green tea may benefit health when consumed in moderation, energy drinks are extremely high in stimulants and added sugar. Thus, you should avoid them whenever possible.
If you’re currently experiencing sleep issues and frequently drink caffeinated beverages, try cutting back to see whether it helps improve your sleep and energy levels.
Inadequate hydration
Staying hydrated is important for maintaining energy levels. The many biochemical reactions that take place in your body every day result in a loss of water that needs to be replaced.
Dehydration occurs when you don’t drink enough liquid to replace the water lost in your urine, stools, sweat, and breath. Being dehydrated leads to lower energy levelsTrusted Source and decreased concentration ability.
Although you may have heard that you should drink eight 8-ounce (240-mL) glasses of water daily, hydration needs depend on several factors, including your weight, age, sex, and activity levels.
The key is drinking enough to maintain good hydration. Common symptoms of dehydration include thirst, fatigue, dizziness, and headaches.
Overweight or obesity
Maintaining a healthy body weight is essential to overall health.
Not only is obesity significantly linked to a greater risk of many chronic illnesses like type 2 diabetes, heart disease, and certain cancers, but it may also increase your risk of chronic fatigue.
Obesity greatly increases your risk of obstructive sleep apnea, which is a common cause of daytime fatigue. It’s also linked to increased daytime sleepiness regardless of sleep apnea, suggesting that obesity directly affects the sleep cycle.
Maintaining a healthy body weight may support good sleep and energy levels, while getting high quality sleep may help prevent weight gain and reduce fatigue.
