How can you boost your energy?

Energy is the fuel that powers our body and our mind, letting us carry out our daily activities, physical and mental alike. In our modern society, though, many people complain of persistent fatigue and falling energy, which can affect their productivity and their general wellbeing. Understanding how to boost your energy effectively and lastingly is therefore essential to improving your quality of life. This article explores scientifically proven ways to increase energy, drawing on recent clinical studies, carried out mainly in France.

The common causes of fatigue

Before turning to the solutions for increasing energy, it is important to understand the underlying causes of fatigue. It can be linked to several factors, often interdependent.

1. Lack of sleep

Sleep is fundamental to physical and mental recovery. While we sleep, the body regenerates, repairing tissue, consolidating memories and regulating hormones. With stress and professional and social obligations, though, many people sleep less than the 7 to 9 hours recommended by experts. A study by the Montpellier university hospital found that people who sleep less than 6 hours a night have significantly lower energy levels than those who sleep between 7 and 8 hours.

2. An unbalanced diet

What we eat plays a crucial part in how we feel through the day. A diet rich in refined sugars and saturated fats, and poor in essential nutrients, can produce energy peaks followed by sharp drops, which can contribute to a feeling of continuous fatigue. A study published by Inserm showed that the balance between macronutrients, carbohydrate, protein and fat, is crucial to maintaining steady energy levels. Unbalanced diets, particularly those lacking protein and fibre, can cause increased fatigue.

3. Lack of physical exercise

It may seem paradoxical that physical exercise, which uses energy, can actually provide more of it. But regular physical activity is one of the most effective ways to increase your energy level in the long term. A study at the University of Strasbourg showed that participants who took regular physical activity for three months reported a 20% increase in their energy level, thanks to better blood circulation, greater oxygenation and the release of endorphins, the wellbeing hormones.

4. Stress and anxiety

Chronic stress and anxiety are major drains on our energy. They place excessive demands on the nervous system, which can lead to mental and physical fatigue. Researchers at the University of Grenoble have highlighted the role of stress hormones such as cortisol in energy depletion. Prolonged exposure to high cortisol levels can disturb sleep, increase cravings for sugary foods and reduce the motivation to exercise, creating a vicious circle of fatigue.

1. Macronutrients and energy

As mentioned above, a balanced diet is essential to maintaining steady energy levels. Carbohydrates are the body's main source of energy, but not all carbohydrates are equal. Complex carbohydrates, such as those in whole grains, vegetables and pulses, are digested more slowly, providing a more lasting source of energy. Simple sugars, present in processed foods, can cause rapid rises in blood sugar followed by sharp falls, leading to fatigue and irritability.

Proteins, for their part, are crucial to repairing tissue and maintaining muscle mass, which is essential to lasting energy, particularly in physically active people. Fats, often feared, are also necessary, omega-3 fatty acids in particular, which play a part in cognitive health and mood regulation.

2. Micronutrients and their role in fatigue

Beyond macronutrients, micronutrients, although needed in small amounts, are essential to maintaining energy. The B vitamins, for example, are involved in energy metabolism, helping convert the food we eat into usable energy. A study at the University of Bordeaux showed that deficiencies in vitamin B12 in particular can cause fatigue, because of its crucial role in producing red blood cells, which carry oxygen throughout the body.

Iron is another essential nutrient, especially for women of childbearing age, since a deficiency can lead to anaemia, a condition that reduces the blood's ability to carry oxygen and causes intense fatigue. Iron supplementation, according to a study at the University of Lille, produced a significant improvement in energy levels in women with an iron deficiency.

Physical exercise as an energy booster

1. The impact of regular physical activity

Exercise is a fundamental pillar of increasing your energy, because it stimulates blood circulation, supports better oxygenation of the tissues and contributes to the release of endorphins. These are often called the "happiness hormones" for their ability to improve mood and reduce stress, two crucial factors in maintaining optimal energy.

The University of Strasbourg study showed that even moderate physical activity, such as a brisk 30-minute walk a day, can have significant effects on energy levels. Participants reported reduced fatigue and greater motivation to get through their daily tasks.

2. Why exercise should suit your way of life

It is essential, though, to choose a type of exercise suited to your way of life and your personal preferences. An exercise programme that is too intense can, conversely, increase fatigue, especially in people not used to physical activity. It is therefore recommended that you start with gentle exercise, such as yoga or swimming, and increase the intensity gradually.

A study at the University of Lyon showed that participants who worked strength training into their weekly routine not only improved their physical strength but also reported better endurance and less general fatigue. Strength training helps maintain good posture, reduces the risk of injury and supports healthy muscle mass, which is crucial to sustained energy.

The role of nutritional supplements

1. Essential vitamins and minerals

In an ideal world we would get all the nutrients we need from our diet alone. Because of the variable quality of food, restrictive diets, or increased needs for certain nutrients, though, it can be necessary to turn to nutritional supplements to fill the gaps.

The B vitamins, B12 in particular, play a central part in energy metabolism. A study at the University of Bordeaux showed that vitamin B12 supplementation in people with a deficiency led to a significant reduction in fatigue and an improvement in mental energy. This vitamin is particularly important for vegetarians and vegans, since it is found mainly in animal products.

Magnesium is another mineral crucial to energy, involved in more than 300 enzymatic reactions in the body, including the production of ATP, the main energy molecule in our cells. A study at the University of Montpellier showed that magnesium supplementation in people with chronic fatigue improved their energy levels and reduced their fatigue symptoms.

2. Adaptogens and other natural supplements

Adaptogens are a category of medicinal plants that help the body adapt to stress and maintain energy balance. Ginseng, for example, is widely used in traditional medicine for its energising properties. A study at the University of Paris showed that ginseng can improve energy levels in people with chronic fatigue by modulating the stress response and improving cognitive function.

Rhodiola rosea is another popular adaptogen, often used to combat fatigue and improve mental and physical endurance. A study at the University of Toulouse demonstrated that rhodiola can reduce stress-related fatigue symptoms and improve physical performance.

The benefits of restorative sleep

1. Understanding sleep cycles

Sleep is not a uniform state; it is made up of several cycles, each playing a specific part in restoring our energy. The deep slow-wave sleep phases are crucial.

The benefits of restorative sleep. Quality sleep is essential to restoring energy levels. A study by the Montpellier university hospital showed that people who sleep between 7 and 8 hours a night have higher energy levels than those who sleep less than 6 hours.

Conclusion. Boosting your energy calls for a holistic approach, combining diet, exercise, sleep and possibly supplements. By adopting these practices it is possible to recover and maintain optimal energy levels.
