Feeling Tired, Stressed or Craving Sugar?

In the previous article, we explored how stress activates the body’s natural fight-or-flight response and how ongoing stress can affect energy, sleep, and overall well-being. In this article, we’ll look more closely at how stress affects hormones in both men and women, and why this can influence things like energy levels, mood, cravings, and weight regulation.

Felling Tired, Stressed or Craving Sugar?

Hormones act as the body’s internal communication system, helping regulate metabolism, appetite, sleep, mood, and reproductive health. When stress becomes ongoing, it can disrupt this delicate balance and lead to noticeable changes in how the body feels and functions. Understanding this connection can help explain why many people begin to experience shifts in energy, sleep, appetite, and recovery during periods of prolonged stress.

The Stress Hormone: Cortisol

One of the main hormones involved in the stress response is cortisol, produced by the adrenal glands.

In healthy situations, cortisol follows a natural daily rhythm:

• Higher in the morning to help us wake up and feel alert • Gradually declining throughout the day • Lower in the evening to allow the body to relax and prepare for sleep

However, when the body experiences ongoing stress, cortisol levels can remain elevated for longer periods.

Over time this can influence several areas of health, including:

• sleep quality • appetite regulation • energy levels • immune function • mood and mental clarity • fat storage

When stress becomes chronic, the body may begin prioritising short-term survival over long-term balance, which is where hormonal changes can begin to appear.

How Stress Affects Hormones in Women

Women’s hormones are particularly sensitive to stress because of the complex relationship between cortisol, oestrogen, and progesterone. When stress levels remain high, the body may divert resources toward producing stress hormones rather than reproductive hormones. This can contribute to symptoms such as:

• disrupted sleep • increased fatigue • mood changes • stronger cravings • irregular menstrual cycles • weight changes, particularly around the abdomen

For many women, these effects can become more noticeable during peri-menopause and menopause, when hormonal fluctuations are already taking place. During this time, the nervous system may become more sensitive to everyday pressures, which is why managing stress becomes even more important.

How Stress Affects Hormones in Men

Stress also influences testosterone, the primary hormone responsible for many aspects of male health including energy, muscle maintenance, motivation, and recovery. When cortisol remains elevated for long periods, it can interfere with testosterone production. Men experiencing ongoing stress may notice:

• lower energy levels • reduced motivation • slower recovery from exercise • reduced muscle mass • increased abdominal fat • sleep disturbances

Because testosterone levels naturally decline gradually with age, chronic stress can sometimes make these effects more noticeable. Supporting the body with healthy routines, recovery, and regular movement can help counteract some of these effects.

Stress, Appetite and Cravings

Many people notice that stress affects their eating habits. This is not simply about willpower — hormones play a significant role. When cortisol rises, the body may increase cravings for quick-energy foods, particularly those high in sugar or refined carbohydrates. At the same time, stress can influence other appetite hormones that regulate hunger and fullness, which may make it easier to overeat during stressful periods.

Breaking the Stress–Energy Cycle

Chronic stress can create a cycle that affects several areas of daily life. For example:

• Poor sleep leads to fatigue

• Fatigue increases reliance on caffeine or sugary foods

• Energy crashes reduce motivation for movement

• Less movement can affect mood and metabolism

Over time this can leave people feeling constantly tired, overwhelmed, and stuck in a pattern of low energy.

The encouraging news is that small daily habits can make a meaningful difference.

The Role of Movement in Managing Stress

One of the most effective ways to help regulate stress hormones is regular movement.

Exercise helps the body process stress hormones more effectively while supporting the release of endorphins — often referred to as the body’s natural “feel-good” chemicals. Regular movement can help:

• improve sleep quality

• boost mood and resilience

• increase energy levels

• support metabolic health

• reduce tension and stress

Importantly, exercise does not need to be extreme to be effective. In many cases, consistent, balanced movement is exactly what the body needs.

Move, Relax and Support Your Well-being

If you’ve been feeling the effects of stress — low energy, poor sleep, tension, or feeling constantly switched on — regular movement can be one of the most powerful ways to help your body reset.
