Adjusting your rest according to the sky ensures deep regeneration throughout the year. When Agni, the digestive fire, is peaceful, sleep becomes peaceful. Your nervous system needs to feel sheltered to release into true rest. Conversely, when testosterone drops, life feels dull. No tonic or tablet can replace what the body forgets how to create naturally. You live what the sages called Yogaha Karmasu Kaushalam—excellence is alignment. You begin to eat when the stomach asks, rest when the mind softens, love when the heart opens, and work when the brain is sharp. IGF-1 is a potent anabolic hormone that promotes muscle cell survival and inhibits apoptosis (programmed cell death). By slowing this pathway, testosterone minimizes muscle wasting, even under conditions that would typically trigger catabolism, such as caloric deficits or prolonged exercise. By suppressing cortisol levels, testosterone creates an environment where muscle preservation is prioritized, preventing the loss of hard-earned muscle mass. However, little is known regarding RT and potential up-regulation of co-activators which may serve as a great area of interest for future research. The AR LBD coactivator binding groove is a target of drugs to manipulate AR activity especially in the development of anti-prostate cancer drugs (63). Micro RNAs have been shown to mediate AR function via co-repressor expression inhibition (62). Co-activators augment transcriptional activity and enhance signaling, e.g., SRC-1, SRC-3, TIF-2, ARA24, ARA160, BAF57, BAF60A, ARA54, ARA70 whereas co-repressors (e.g., SMRT, SIRT1, Ankrd1) reduce transcriptional activity. Androgen binding to the AR completes the groove that serves as a recruiting surface for co-activators (attract co-regulator motifs, e.g., LxxLL, FxxLF) that form a bridge between the DNA-bound AR and the transcriptional machinery. It means using your forces wisely—letting sleep, food, and thought nourish rather than exhaust you. That is why the masters of old always taught Brahmacharya, not as celibacy but as energy conservation. Overindulgence, overwork, excessive sexual activity, and sleeplessness all dry up this sacred essence. If sleep deprivation interrupts that process, your system simply can’t complete the final refinement. A peripheral clock system is present in a human adrenocortical cells where periodic oscillations of clock genes are influenced by glucocorticoids, mainly through GRα (230). Sensitivity to glucocorticoids varies among individuals, among tissues from the same individual, and even within the same cell depending on the phase of the cell cycle (223). Moreover, overexpression of GRβ may preserve skeletal muscle mass in the presence of glucocorticoids by increased MyoD (1.8-fold) and myogenin (2.5-fold) gene expression, two muscle regulatory factors necessary for skeletal muscle development and regeneration (201). Myotubes overexpressing GRβ have lower forkhead box O3 (FOXO3a) mRNA levels and a blunted muscle atrophy F-box/atrogen-1 (MAFbx) and muscle ring finger 1 (MuRF1) response to glucocorticoids (201).
