The Circadian Clock and Aging

The Circadian Clock and Aging: How Sleep Affects Longevity and Wellbeing

August 21, 2026

The circadian clock is more than just a regulator of daily rhythms – it’s a key player in the aging process. The body’s internal 24-hour timer regulates sleep, metabolism, hormone release, and other physiological processes in sync with day-night cycles, and preserving its function may be as important to healthy aging as managing other age-related risk factors. Circadian rhythms are essential for health, and their disruption is linked to numerous age-related diseases, so maintaining the circadian clock is an important factor in increasing longevity and boosting healthspan.

Autophagy and Aging

Autophagy and Aging: A Look at Nature’s Source of Cellular Health, Energy Balance, and Longevity

August 14, 2026

Autophagy is the body’s cellular cleanup process, a method of removing damaged proteins, organelles, and pathogens by encircling them in double-membrane structures called autophagosomes. The autophagosomes fuse with lysosomes, degrading and recycling the damaged cellular material into reusable building blocks like amino acids, fatty acids, and nucleotides to maintain cellular homeostasis, enable metabolic adaptation, and support the cellular stress response. Genetic and experimental evidence shows that longevity paradigms rely on basal autophagic activity, and that activating autophagy may extend lifespan and promote longevity.

Making the Most of Menopause: Aging and Autoimmunity in Women

May 15, 2026

The relationship between menopause and autoimmune disease is a women’s health issue that can no longer be ignored. Autoimmune diseases affect women far more often than men, with women accounting for approximately 80% of cases. Hormonal fluctuations during perimenopause and menopause — particularly declining estrogen levels — are associated with an increase in certain immune cells and antibodies that may worsen or contribute to disease onset.

Rheumatoid arthritis, lupus, Sjögren’s syndrome, and psoriatic arthritis are among the autoimmune conditions linked to menopause. Declining estrogen levels during this transition can increase inflammation and reduce the effectiveness of immune regulation. Although hormone therapy use in postmenopausal women has been associated with a higher incidence of certain autoimmune conditions, it has also emerged as an important tool for symptom management and improving quality of life when appropriately monitored.
