Sleep is regulated by a complex interaction of physiological and psychological factors. Some of the key factors that contribute to the onset of sleep in humans include: 1. Circadian Rhythms: The body's internal clock, which regulates the sleep-wake cycle based on a 24-hour day. Melatonin, a hormone produced by the brain's pineal gland, plays a key role in regulating these rhythms. 2. Adenosine: Adenosine is a chemical in the brain that builds up during wakefulness and promotes sleep. When adenosine levels are high, it signals to the body that it's time to rest. 3. Neurotransmitters: Various neurotransmitters, such as serotonin and gamma-aminobutyric acid (GABA), play a role in promoting sleep and relaxation. 4. Environmental Cues: External factors such as light, temperature, and noise can influence the body's readiness for sleep. 🧪🦠@Biochemistryscience🦠🧪
