Immune
Surveillance and repair
Your immune system balances defense against pathogens with tolerance of self and environment. It is modulated by sleep, stress, gut health, nutrition, and exposure history.
What it needs
- Adequate sleep (immune function drops sharply with deprivation)
- Diverse nutrition with sufficient protein
- Regular moderate movement
- Gut microbiome support
- Stress regulation
What wrecks it
- Chronic sleep restriction
- Sustained psychological stress
- Nutrient deficiencies
- Sedentary lifestyle
- Social isolation
Indicators to observe
- Infection frequency and recovery time
- Autoimmune symptoms (if present)
- Allergy and sensitivity patterns
- Inflammation markers (CRP, if tested)
- Wound healing speed
What the evidence shows
Sleep-immune connections are among the strongest in health research. Thymosin alpha-1 has immunomodulatory evidence but most peptide immune claims remain preclinical.
Open questions
- Long-term effects of immunomodulatory peptides
- Optimal exercise dose for immune function
- Autoimmune trigger identification in individuals
