attempt to “top up” their sleep by sleeping more longer on the weekend. However‚ healthy sleep is best done at the same time‚ and in the same quantity every day . Therefore‚ such irregularities in sleep pattern produce an unhealthy circadian rhythm disorder (delayed sleep phase disorder) that occurs in approximately 12% of university students‚ which is double the frequency in the general population (6%–7%). Individuals with delayed sleep phase disorder have difficulty falling asleep during

Primarily‚ sleep is fashioned in the human body to repair and recover from the daily grinds of life. NHLBI (2017) included the 24-hour circadian rhythm in the body that responds to internal and external cues to induce sleep. Internally‚ NHLBI (2017) explained that the accumulation of adenosine and melatonin causes the body to fall asleep while the external cues come from body’s reaction to

blue hue. Phytochrome can be converted from one form to another by different types of light. Most of the flowering plants use phytochrome to regulate the time of flowering based on the length of day and night (photoperiodism) and to set circadian rhythms. Besides‚ phytochrome also regulates other responses including elongation of seedlings‚ controlling what shape and size leaves form‚ how many leaves form‚ the germination of seeds (photoblasty)‚ the synthesis of chlorophyll‚ and the straightening

Introduction:- Shift work is an employment practice designed to make use of‚ or provide service across‚ all 24 hours of the clock each day of the week (abbreviated as24/7). The practice typically sees the day divided into "shifts"‚ set periods of time during which different groups of workers take up their posts. The term "shift work" includes both long-term night shifts and work schedules in which employees change or rotate shifts. A night shift is determined by the number of hours an employee works

The purpose of this paper is to evaluate the correlational method as a means for examining the relationship between REM sleep and memory. I will describe previous research and then investigate how REM and memory are associated in young people and in older people. In some ways‚ the sleep patterns of these two groups are very similar‚ but in some ways they are not. 1a) In a normal brain‚ the period of deep sleep is the first half of sleep and the period of REM sleep is the second half of sleep.

An estimated 30% -50% of the general population are affected by insomnia‚ and 10% have chronic insomnia. Insomnia is a symptom‚ not a stand-alone diagnosis or a disease. By definition‚ insomnia is “difficulty initiating or maintaining sleep‚ or both” and it may be due to inadequate quality or quantity of sleep. Insomnia could be classified by the
