Fatigue: what are the signs of a lack of hydration?

Dehydration is a condition in which the body loses more water than it absorbs, leading to an imbalance in the fluids and electrolytes essential for the body to function properly. Water is crucial for many bodily functions, including regulating temperature, lubricating joints, and transporting nutrients and oxygen to cells.

Fatigue is a complex state that goes beyond the simple sensation of drowsiness and the desire to sleep. It is the body's response to a variety of internal and external factors, manifesting itself in a diminished ability to perform normally simple physical or mental activities. Fatigue can be acute, resulting from intense effort, or chronic, if it develops over a long period of time.

Lack of sleep and quality of sleep: The night is the time when the body regains its strength, when everything the brain has stored during the day is recorded in the memory. A lack of sleep, whether due to irregular bedtimes, sleep disorders or insufficient sleep time, can lead to fatigue of varying degrees. It is recommended that adults sleep between 7 and 9 hours a night to be in peak condition. However, some people need as little as 5 hours' sleep to be in top form, while others need 10 hours' sleep to feel rested. Sleep is different for everyone, but it's essential to get good quality sleep and maintain a regular bedtime routine to avoid altering the quality of sleep or even falling into hyposomnia.

Poor diet and nutritional deficiencies: Our bodies need energy and fuel to function properly. Its fuel is food, so it needs to be fed properly and according to its needs. The more sustained your physical effort, the more food your body will need. If you move around and walk a lot during the day, you'll need a lot of food, or you'll risk getting tired. A diet lacking in nutrients can also be responsible for fatigue. Deficiencies in iron, B vitamins and other nutrients can affect the body's energy production. It is therefore essential to provide all the fibre, vitamins and fats our body needs to avoid episodes of fatigue.

Stress and overwork: Chronic stress and overwork are major contributors to fatigue. When the body is under constant stress, it releases stress hormones such as cortisol, which can disrupt sleep and deplete energy reserves.

To remedy this, you can learn stress management techniques such as meditation, deep breathing and yoga, which will help to reduce the effects of stress on the body. It is also essential to identify and reduce the sources of stress that punctuate our daily lives.

Water is an essential element for life and plays a crucial role in the proper functioning of the body. Around 65% of the human body is made up of water, making it an essential component in a number of biological functions. It is involved in regulating body temperature, digestion, absorption of nutrients and elimination of waste.

When the body is well hydrated, the cells function optimally, easily maintaining adequate energy levels. Water also facilitates the transport of nutrients to the cells, promoting better use of nutrients for energy production.

Water deficiency and loss of energy: Dehydration can quickly lead to a loss of energy. When the body lacks water, blood circulation can become less fluid, reducing the supply of oxygen and nutrients to the cells and leading to a feeling of tiredness.

Reduced physical and mental performance: Lack of hydration can also affect physical and mental performance. Studies have shown that even mild dehydration (1%) can lead to reduced physical endurance, impaired concentration and impaired cognitive function.

Recognising the signs of dehydration: It is essential to recognise the symptoms of dehydration, because if they are not recognised, they can lead to severe chronic fatigue. Common signs include feeling thirsty, dry mouth, headaches, dry skin and dark urine. If you experience dizziness and nausea, this may be a sign of severe dehydration, so it's vital that you drink quickly! On average, it is recommended that you drink at least 1.5 litres of water a day for an adult weighing around fifty kilos.

The Vicious Circle of Dehydration and Fatigue: Dehydration can create a vicious circle with fatigue : lack of water leads to fatigue, while fatigue reduces the sensation of thirst. To stay in good health and avoid feeling tired, it's essential to hydrate regularly, even before you feel thirsty.

Maintaining adequate hydration is an essential pillar of fatigue prevention. Water is the main constituent of our body and is involved in almost every biological process. To prevent fatigue, it is crucial to constantly meet the body's water needs. Taking a proactive approach to hydration can help maintain optimal energy levels.
