Physical exercise is not just a mechanical stimulus on the muscle. It is an integrated biological stressor, with simultaneous impact on the metabolic, endocrine, nervous, and immune systems. The response to exercise depends on intensity, duration and the organism's internal context, and this context, in the female body, varies cyclically. Ignoring the menstrual cycle is...
The human body works according to an internal clock known as the circadian rhythm. This system plays a part in organising multiple biological functions, such as sleep, appetite, body temperature, hormone production, energy levels and mood. This rhythm is naturally synchronised with the cycle of light and darkness, i.e. with...
Melatonin is a central hormone in the regulation of the sleep-wake cycle and plays an important role in the overall physiological balance. It is associated with the organisation of the circadian rhythm, the quality of sleep and various adaptive processes in the body. Although it is commonly known as the “sleep hormone”, its regulation depends to a large extent on...
Physical exercise not only benefits cardiovascular and muscular health, but also plays a fundamental role in regulating inflammation and strengthening the immune system. One of the main reasons for this positive effect lies in the release of interleukin-6 (IL-6) by the muscles during physical activity. How Exercise Reduces...
Incorporating more physical activity into everyday life doesn't require radical changes or complex routines. Small adjustments to everyday life can have a significant impact on physical health, emotional balance and the body's ability to adapt. Regular movement contributes not only to physical fitness, but also to regulating the nervous system,...
The use of electronic devices is part of most people's daily lives. Computers, smartphones and tablets are often used until very close to bedtime, which raises clinically relevant questions about the impact of the blue light emitted by these screens on sleep organisation. Understanding these effects is essential to...
Health and quality of life result from the interaction between genetic, physiological, environmental and behavioural factors. Although not all of these factors can be modified, a significant part of health status is related to everyday choices and habits. Focusing on aspects that can be adjusted is an important step towards promoting...
Have you ever stopped to think about why you need to rest? It is widely known that taking a break is beneficial for health, but delving into the reasons for this need is crucial to understanding the consequences of inadequate rest. Some of these consequences are Increased irritability. A tendency to forgetfulness. Decreased productivity. Lack of energy....
In an increasingly fast-paced lifestyle, sleep is often undervalued, despite its central role in regulating the immune system. The relationship between sleep, cell repair and immune response is now well documented and is recognised as one of the most important elements in maintaining health over time. The importance of...
The circadian cycle is an approximately 24-hour biological regulation system responsible for organising multiple physiological processes, including sleep, wakefulness, metabolism and the response to stress. Among its main modulators are cortisol and melatonin, two hormones with complementary functions in the body's adaptation to different...
