Circadian rhythm

abstinence from food and drink.24 In some places, IF has been practiced since the earliest of antiquity depending on culture and lifestyle. IF regimens are linked to certain health outcomes and influence metabolic regulation via effects on the circadian biology.24 Several cross-sectional and longitudinal studies have shown that IF has positive effects on physical and intellectual performance by affecting various aspects of physiology and biochemistry.25 Other studies have shown that IF…

becoming a more prominent issue due to the rising number of electronic devices. Because of the blue light illuminance these devices produce, the brain’s secretion of the sleep-inducing chemical melatonin is disrupted; therefore, impacting the circadian rhythm of the human body. Since society continues to stare at screens late into the night or right before bed because of school, work, or entertainment, the blue light emittance disrupts sleep patterns and damages the retina of the eyes. However,…

animals and from evidence of other behaviors and illnesses. Although most sleep disorders have probably been present since man evolved, modern society has inadvertently produced several new disorders. Delayed sleep phase syndrome: One of the circadian rhythm sleep disorders. It is characterized by sleep onset and wake times that are usually later than desired, with difficulty in initiating sleep onset. Once sleep onset does occur, sleep is of good quality, with few awakenings until the time of…

sleep medicine (American academy of sleep medicine, 2010), circadian rhythm sleep disorders (CRSD) results from timing when a person is awake and when sleeps. Humans have an internal clocks in the brain called suprachiasmatic nucleus (SCN), where primary circadian rhythm help control the body sleep-wake cycle. This circadian clock is set by visual stimulation using light and darkness using the eyes and guides. Some examples of circadian rhythm sleep disorders are person have a hard time…

is the hormone melatonin. Melatonin plays two major roles in the physiology of sleep. Its first role is to encourage sleep, and its second role is to help the brain transition through the different stages of sleep in accordance with the body’s circadian rhythm. The production and release of melatonin indicate the beginning of the sleep-wake cycle. What…

These rhythms are controlled by a combination of two internal influences, homeostasis and circadian rhythms. First we examine homeostasis. According to the article “The Drive to Sleep an Our Internal Clock” presented by the Department of Sleep, Harvard University, homeostasis is the process by which the body…

nursing home patients with Alzheimer's disease and related dementia, and used the light source that produced low levels of 300 to 400 lux of a bluish-white light with a color temperature greater than 9000 K. The goal was to target the patient's circadian rhythms by installing the light source inside each resident's room for 4 weeks. A calibrated…

1. The role that dental sleep medicine plays in the overall treatment of some patients with sleep disorders can be very beneficial, especially using combination therapy. Although, dental sleep medicine alone is being used but not recommended for patients with significant sleep apnea (AHI > 25/hr.). Preferably dental sleep medicine is at its best if patients with OSA can’t tolerate PAP therapy, or the oral appliance therapy alone is not adequately effective. There are several reasons that…

wake up. This “internal clock” is better known as the, circadian rhythms of the body. Circadian rhythms have an effect on the body temperature, sleep and wakefulness, and various hormonal changes. In order for an individual to perform at its highest potential, and be alert, one must keep their circadian rhythms fine-tuned by getting enough sleep. The pineal gland plays a huge role in helping the body produce melatonin to help maintain these rhythms. When an individual…

specifically, Konnikova argues that certain environmental discrepancies can upset our body's circadian clocks, hence preventing us from falling asleep. She writes, "Her research tracks how multiple individual differences in our environment affect our circadian rhythms and our ability to fall asleep easily and soundly". This indicates that individuals need to participate in certain behaviors that avoid knocking off our circadian clocks. Konnikova refers to these behaviors as sleep hygiene. She…
