Misalignment

A state where one's actions, job, or lifestyle do not resonate with their true self or values, leading to emotional and physical tiredness, often overlooked as a cause of fatigue.

Sleep Quality

Refers to the depth and restorative nature of sleep, distinct from mere sleep duration. One can sleep for many hours but still wake up tired if the sleep quality is superficial or light.

Blood Sugar Roller Coasters

The rapid fluctuations in blood glucose levels, typically caused by consuming ultra-processed foods or excessive carbohydrates, leading to energy spikes followed by crashes and feelings of tiredness and hunger.

Insulin Resistance

A condition where the body's cells become less responsive to insulin, requiring the pancreas to produce more insulin to maintain normal blood sugar levels, often linked to modern lifestyle factors and metabolic dysfunction.

Continuous Glucose Monitor (CGM)

A device worn on the body that measures glucose levels in real-time throughout the day, providing insights into how different foods and activities affect an individual's blood sugar.

?
Why do I feel tired even after getting enough sleep?

You might be experiencing low energy due to factors beyond sleep quantity, such as misalignment with your values, poor sleep quality, lack of daily movement to process stress, or blood sugar imbalances from your diet.

?
How does emotional state affect physical energy?

Emotional factors like misalignment, unresolved stress, people-pleasing, lack of meaning, or loneliness can manifest as physical tiredness, demonstrating that energy is not solely physical.

?
What should I do in the hour before bed to improve sleep?

Focus on relaxing inputs like music, gentle yoga, or calming audiobooks, and avoid stressful activities like watching news or doing work emails to promote restful sleep.

?
How does daily movement impact sleep quality?

Moving your body throughout the day, even with short walks, helps process accumulated stress and emotions, which can significantly improve the quality and restorative nature of your sleep.

?
Can my diet contribute to feeling low in energy?

Yes, consuming ultra-processed foods or too many carbohydrates can cause blood sugar spikes and subsequent crashes, leading to feelings of tiredness and low energy.

?
What are common medical reasons for persistent exhaustion?

Persistent exhaustion can be a symptom of underlying conditions such as iron deficiency, sleep apnea, thyroid issues, depression, anxiety, or burnout, warranting a visit to a healthcare professional.

1. Address Life Misalignment

If you feel tired doing things that don’t light you up, ask yourself what gives and drains your energy, and where you abandon your needs, then take small steps to change it.

2. Optimize Pre-Sleep Hour

Dedicate the hour before bed to relaxing activities, avoiding stressful inputs like news or work emails, to signal to your body that it’s time to wind down and improve sleep quality.

3. Move Body to Process Stress

Incorporate physical movement throughout the day, such as a 30-minute lunch walk or a 10-minute evening walk, to process stress and emotions, which can significantly improve sleep quality.

4. Balance Blood Sugar with Food

Reduce ultra-processed foods and prioritize protein and healthy fats at each meal to keep blood sugar stable, preventing energy crashes and the vicious cycle of fatigue and increased cravings.

5. Monitor Post-Meal Energy

Pay attention to how you feel two hours after lunch or dinner, as post-meal tiredness and hunger could indicate a blood sugar issue that needs dietary adjustment.

6. Seek Professional Medical Advice

If persistent exhaustion continues, consult a healthcare professional to rule out underlying medical conditions like iron deficiency, sleep apnea, thyroid issues, depression, anxiety, or burnout.

I think a lot of the time we think about tiredness as only physical, but it can also be emotional.
