“…Sleep is by definition a state of unconsciousness, which is altered when a stimulus hits us; and it is classified into two types, called REM sleep (Rapid Eye Movement) and slow-wave sleep or NREM (Non-Rapid Eye Movement) [1]. NREM sleep is divided into stages (1,2,3,4) and REM sleep, with a young adult, usually having four to six cycles of these, depending on the total amount of hours of sleep. The first cycle lasts approximately 90 minutes, being marked by the transition from the relaxed waking state to stage 1, and then to stage 2; sleep deepens and reaches stages 3 and 4 (NREM).…”

“…Sleep has an important relationship with food, mainly due to the possibility of sleep deprivation increases hunger by increasing ghrelin secretion and decreasing leptin secretion [4]. Skipping breakfast and eating irregularly throughout the day, low intake of high-quality carbohydrates, low protein intake, frequent consumption of energy, and sugary drinks, is related to sleepless nights [5].…”

Chronobiology is the process that studies the biological rhythms of living beings, in which each organism has its own biological clock. Sleep is a state of unconsciousness, characterized by the active inhibitory process, and that has an important relationship with feeding, mainly due to the possibility of sleep privation increasing starvation through hormonal regulation. In addition, starvation can lead to obesity, contributing to the risk factors for chronic non-communicable diseases, such as high blood pressure, hypercholesterolemia, diabetes mellitus, cardiovascular diseases, and some forms of cancer. The cycle of bad sleep may cause direct health problems, such as the diseases mentioned above; and indirect, may result in traffic accidents, unemployment, and difficulties in interpersonal relationships, with the possibility of progressing to anxiety disorders. This study aims to analyze whether there is a relationship between healthy eating and the standard of sleep quality, providing better performance of daily activities. For this study, the 133 participants answered 3 feeding records and, later, questionnaires on sleep quality (Pittsburgh Sleep Quality Index) in three moments. Considering the three questionnaires, there were no significant differences obtained by calculating the statistical tests, however, the analysis of the gross medians with the proposed score showed a strict relationship between sleep and food. In addition to the relationship between food and sleep quality, other factors such as stress and anxiety can contribute to hormonal dysregulation, thus changing the pattern of sleep quality of individuals.

O ciclo sono-vigília é parte do ritmo circadiano do indivíduo, sendo de grande valia para um bom funcionamento do organismo. Sua regularidade e eficiência, bem como uma fuga dessas pode levar a grandes alterações em todos os outros mecanismos sono dependentes. O ciclo que regula o sono é influenciado por fatores endógenos (relógio biológico baseado nos clock genes) e fatores exógenos ou ambientais (Zeitgebers). O período de sono é de suma importância para a saúde física e mental, interferências acarretam uma série de efeitos negativos ao organismo em questão. O objetivo do presente trabalho foi realizar uma revisão de literatura especializada, inicialmente, levantando parâmetros gerais fisiológicos, que envolvem a cronobiologia, em seguida, a caracterização dos cronotipos e a sua variação entre os grupos populacionais, dando ênfase para estudantes universitários de períodos do dia diferentes, destacando-se os cronotipos, que mais aparecem no público mencionado. Entre os existentes (matutino, indiferente e vespertino), o predominante na população estudada é o indiferente, seguido do vespertino e matutino. Há fatores fisiológicos que são fortemente influenciados pelo cronotipo como as acrofases de temperatura corporal e liberação de cortisol, bem como o horário de início da liberação de melatonina (hormônio do sono), em que se percebeu que tais fatores são adiantados no indivíduo matutino em relação ao vespertino em aproximadamente duas horas. É de grande importância a identificação dos cronotipos, em cada indivíduo, para uma correta alocação de atividades relacionadas ao ritmo circadiano, visando um maior aproveitamento do mesmo, bem como não prejudicando processos de aprendizado e de decodificação de informações. Palavras-chave: Cronotipo. Universitários. Fisiologia. Qualidade do Sono. AbstractThe sleep-wake cycle is part of the individual’s circadian rhythm, being of paramount importance for a good functioning of the organism. Its regularity and efficiency as well as an escape from these can lead to major changes in all the other sleep dependent mechanisms. The cycle that regulates sleep is influenced by endogenous factors (biological clock based on clock genes) and exogenous (or environmental, Zeitgebers) factors. The sleep period is of paramount importance to the physical and mental health, interferences entail a series of negative effects to the organism in question. The objective of the present work was to perform a review of specialized literature, initially raising general physiological parameters involving chronobiology, then characterizing chronotypes and their variation among population groups, with emphasis on university students, especially chronotypes that appear more often in the aforementioned public. Among the existing ones (morning, indifferent and evening), the predominant in the studied population is the indifferent, followed by the evening and morning ones. There are physiological factors that are strongly influenced by the chronotype as the acrophases of body temperature and cortisol release, as well as the start time of the melatonin release (sleep hormone), where it was perceived that such factors are advanced in the morning individual in relation to the afternoon in about two hours. It is of great importance to identify the chronotypes in each individual for a correct activities allocation related to the circadian rhythm, aiming a greater use of the same as well as not harming learning processes and information decoding. Keywords: Chronotype. University students. Physiology. Sleep Quality.
