Struggling with Fatigue? How a Sleep & Energy Levels Test Can Help
Do you wake up feeling exhausted, no matter how much sleep you get? Do you struggle with brain fog, low motivation, or difficulty focusing throughout the day? If so, your body might be trying to tell you something. Sleep and energy levels are influenced by a complex interaction of hormones, nutrients, and metabolic health—and imbalances in these areas could be the root cause of your fatigue.
Why Do Sleep & Energy Levels Matter?
Your body relies on a fine-tuned balance of hormones and nutrients to regulate energy, metabolism, and restorative sleep. Disruptions in these systems can lead to persistent fatigue, trouble sleeping, and a general sense of exhaustion. Common signs of an imbalance include:
-
Difficulty falling or staying asleep
-
Waking up unrefreshed, even after a full night’s sleep
-
Constant tiredness, regardless of rest
-
Struggling with brain fog or memory issues
-
Mood swings, anxiety, or low motivation
-
Unexplained weight gain or trouble losing weight
Several factors can contribute to these symptoms, including hormonal imbalances, nutrient deficiencies, chronic stress, and metabolic issues. Identifying these underlying causes is key to improving sleep quality and energy levels.
How Do Hormones and Nutrients Affect Sleep & Energy?
Your body's ability to rest and recharge depends on multiple biological factors. Here’s how some of the key components play a role:
1. Hormonal & Sleep Regulation
-
Thyroid Function (TSH, FT4) – The thyroid plays a major role in metabolism and energy regulation. An underactive thyroid (hypothyroidism) can cause sluggishness, while an overactive thyroid (hyperthyroidism) can lead to restlessness and difficulty sleeping.
-
Cortisol – Often referred to as the "stress hormone," cortisol affects the body's sleep-wake cycle. Elevated cortisol levels can make it difficult to relax and fall asleep, while low cortisol can contribute to chronic fatigue and low energy.
2. Nutrient & Energy Markers
-
Iron Studies (Iron, Ferritin, TIBC) – Iron is essential for oxygen transport in the blood. Low iron levels can lead to anaemia, causing symptoms like tiredness, dizziness, and poor concentration.
-
Vitamin D – Known for supporting bone health and immune function, vitamin D also plays a role in mood regulation and sleep quality. A deficiency has been linked to insomnia and daytime fatigue.
-
Vitamin B12 – Vital for red blood cell production and neurological health, low B12 levels can result in weakness, poor memory, and persistent tiredness.
3. Blood Sugar & Metabolic Health
-
HbA1c – This test measures long-term blood sugar control. Fluctuations in glucose levels can lead to energy crashes, disrupted sleep, and increased risk of metabolic disorders.
When Should You Consider Testing?
Understanding whether sleep disturbances and fatigue are caused by biological imbalances can help you make targeted improvements. You may benefit from a comprehensive sleep and energy test if you:
-
Have ongoing sleep difficulties despite making lifestyle adjustments.
-
Experience daytime drowsiness, lack of concentration, or brain fog.
-
Have unexplained weight changes, mood swings, or stress-related fatigue.
-
Suspect a thyroid disorder, low iron levels, or vitamin deficiencies.
-
Want to take a proactive approach to optimising sleep and energy.
The Nuvivo Deep Sleep & Fatigue Investigation Panel – A Scientific Approach to Better Sleep
The Nuvivo Deep Sleep & Fatigue Investigation Panel is designed to assess key biological markers affecting sleep quality and energy production. By analysing your hormone levels, iron status, and vitamin balance, this test provides valuable insights into potential imbalances.
Unlike general health tests, this specialised panel focuses on the factors most commonly associated with poor sleep, low energy, and chronic fatigue. With detailed lab results, you can gain a clearer understanding of your health and take steps to address any deficiencies or imbalances.
Making Positive Changes for Lasting Energy
Once you understand the root cause of your fatigue, small lifestyle changes can make a big difference. Here are some evidence-based strategies to improve sleep and boost energy:
-
Optimise Sleep Hygiene – Maintain a consistent sleep schedule, limit screen time before bed, and create a relaxing bedtime routine.
-
Manage Stress & Cortisol Levels – Techniques like meditation, deep breathing, and physical activity can help regulate stress hormones.
-
Support Thyroid & Metabolic Health – Ensure adequate intake of iodine, selenium, and B vitamins to support thyroid function.
-
Improve Iron & Vitamin D Levels – Consider dietary changes or supplementation if deficiencies are detected.
-
Stabilise Blood Sugar Levels – Eating balanced meals with protein, healthy fats, and complex carbohydrates can prevent energy crashes.
