Long winter evenings, night travels, artificial light at work\u2026 The winter period is accompanied by a decrease in exposition to light. This leads to a less important synthesis of melatonin, also known as sleep hormone, which manages the circadian cycle. This reduction leads to the feeling of fatigue felt in winter, which is nothing but a biological adaptation.<\/p>\n

Tiredness<\/strong> is a subjective feeling<\/strong> related to the difficulty of acting after work or physical effort, intellectual or mental considered excessive<\/strong>. Three types of tiredness can be distinguished: physical fatigue, nervous fatigue<\/strong> and respiratory fatigue<\/strong>. Generally, they are interdependent. If fatigue sets in regularly (more than six months), it is considered as pathological<\/strong> and called asthenia<\/strong> or even chronic fatigue<\/strong>.<\/p>\n <\/p>\n Muscle fatigue is the inability of some muscles to produce the strength needed to perform a task. The consequences are an inability of muscle fibers to contract, insufficient energy resources<\/strong> and a decrease in nervous message transmission<\/strong>.<\/p>\n Respiratory fatigue is due to a lack of oxygen in the body<\/strong>, allowing the vital muscles and organs to be properly supplied. It is usually felt during intense or prolonged physical exercise.<\/p>\n Finally, nervous fatigue is expressed by the inability of the central nervous system<\/strong> (CNS) to activate muscles to maintain a constant level of strength<\/strong>. When the maximum capacity of the CNS is reached, this force can no longer be maintained.<\/p>\n <\/p>\n Tiredness can result from several causes<\/strong>. The most common are lack of sleep, intellectual or physical overwork<\/strong>, or even an underlying disease<\/strong> such as diabetes, cancer or respiratory disease. Dietary imbalance<\/strong> has a significant influence on fatigue, especially in the case of diet or undernourishment. At the time of menstruation or menopause, women are more likely to be tired due to a lack of iron<\/strong><\/a> or even anemia. Therefore, it is important to ensure that your daily iron needs<\/strong> are met to limit fatigue. It is found in high quantities in red meat, lentils and offals.<\/p>\n Follow our 5 tips to fight tiredness!<\/p>\n [1]<\/a> Dictionnaire m\u00e9dical de l\u2019Acad\u00e9mie de M\u00e9decine, 2018<\/p>\nWhat are the characteristics of different types of tiredness?<\/h2>\n
