Why are women in their 20s constantly feeling exhausted, doctors explain

For many women in their 20s today, feeling tired has become a normal part of life. Long working hours, social pressure, family responsibilities, financial stress, lack of sleep and constant digital exposure are quietly affecting both physical and mental health. What once felt like occasional exhaustion is now becoming a daily reality for many young adults.

Doctors are increasingly noticing that women in their 20s and early 30s are reporting symptoms that were once more commonly associated with long-term stress later in life. Complaints such as constant fatigue, irregular periods, poor sleep, mood swings, hormonal acne, low energy levels, anxiety, brain fog and difficulty concentrating are becoming more common in clinics.

According to Dr Sangeeta Raodeo, Consultant – Obstetrics and Gynaecology at Fortis Hospital Mulund, these symptoms may be connected to what experts are increasingly referring to as “biological burnout.”

Although biological burnout is not officially recognised as a medical diagnosis, the term is being used to describe the effect of long-term physical and emotional stress on the body. Unlike workplace burnout alone, biological burnout affects several systems together, including hormonal balance, sleep quality, metabolism, immunity, emotional health and overall recovery.

WHAT HAPPENS TO THE BODY DURING CHRONIC STRESS?

When the body experiences stress continuously, it repeatedly activates its stress-response system. This causes prolonged release of cortisol and other stress hormones.

Over time, high cortisol levels can start affecting several important body functions, including:

• Sleep quality

• Hormonal balance

• Menstrual health

• Mood stability

• advertisement

  Energy levels

• Appetite and digestion

• Emotional resilience

Doctors say that when the body remains in a prolonged “stress mode,” it struggles to properly recover. This may gradually lead to exhaustion, poor concentration, irritability and worsening physical symptoms.

THE RISE OF THE “ALWAYS-ON” LIFESTYLE

Modern lifestyles are also playing a major role.

Today, many women are balancing careers, relationships, caregiving responsibilities, social expectations and personal goals all at the same time. Digital culture has further added pressure by creating an “always-on” environment where work notifications continue even after office hours, and rest often feels unproductive.

Social media have also intensified unrealistic expectations around success, beauty, fitness, productivity and lifestyle. Constant comparison, emotional overstimulation and inability to disconnect mentally from work or social pressure may contribute to chronic stress and emotional fatigue.

Experts say the body cannot differentiate between emotional stress, workplace pressure, financial anxiety or social stress. It similarly responds to all of them.

HORMONAL HEALTH OFTEN GETS AFFECTED FIRST

One of the earliest systems affected by chronic stress is hormonal health.

Many women are increasingly reporting:

• Irregular menstrual cycles

• Worsening PMS symptoms

• Hormonal acne

• Mood swings

• Fatigue despite resting

• Poor focus

• Reduced stress tolerance

In some cases, chronic stress and unhealthy lifestyle habits may also worsen conditions such as PCOS, thyroid imbalance and metabolic problems.

Doctors say these symptoms are often ignored or normalised until they begin interfering with daily life.

SLEEP DEPRIVATION IS QUIETLY WORSENING THE PROBLEM

Sleep deprivation has emerged as another major health concern among young adults.

Late-night screen exposure, scrolling on social media, anxiety, overthinking and blurred work-life boundaries are disrupting natural sleep cycles. Many women describe themselves as being “tired but wired” — exhausted physically but unable to properly rest mentally.

Health experts warn that poor sleep affects the body’s natural repair system. During deep sleep, the body restores hormones, supports immunity, repairs cells and improves cognitive function.

When sleep is repeatedly disrupted, the body slowly loses its ability to recover fully.

NUTRITIONAL DEFICIENCIES ARE OFTEN OVERLOOKED

Another hidden contributor to exhaustion is poor nutrition.

Doctors say many young adults today are dealing with deficiencies linked to:

• Low iron

• Vitamin D deficiency

• Vitamin B12 deficiency

• Inadequate protein intake

• Excessive caffeine consumption

• Dehydration

• Meal skipping

• Dependence on ultra-processed foods

These deficiencies can trigger symptoms such as fatigue, hair fall, weakness, mood changes, low stamina and brain fog.

Since many of these symptoms overlap with stress and burnout, people often continue functioning without realising that nutritional depletion may also be affecting their health.

WHY EXPERTS SAY THIS CONVERSATION IS IMPORTANT

According to specialists, the concern is not necessarily that women are “ageing faster,” but that prolonged physiological stress is beginning earlier and remaining unaddressed for longer periods.

Long-term health is shaped not only by genetics but also by everyday habits related to stress management, sleep, nutrition, movement and emotional well-being.

Experts say persistent fatigue, poor recovery, low energy and chronic stress should not be accepted as a normal part of modern life.

WHY EARLY ATTENTION CAN HELP

Doctors stress that the purpose of discussing biological burnout is not to create fear, but to encourage early awareness and preventive healthcare.

Symptoms such as:

• Constant tiredness

• Irregular periods

• Sleep problems

• Brain fog

• Mood changes

• Low stress tolerance

• Persistent exhaustion

Should not be repeatedly ignored or normalised.

Experts recommend regular health check-ups, hormonal evaluation, better sleep habits, balanced nutrition, physical activity and emotional support systems to improve long-term health and recovery.

Sometimes, what appears to be “just stress” may actually be the body’s earliest signal that it needs attention.
