What is persistent fatigue?

Persistent fatigue is more than just feeling tired after a busy week or a poor night’s sleep. It’s an ongoing sense of low energy that doesn’t improve with rest.

People describe it as:

• Feeling physically drained

• Mental fog or difficulty concentrating

• Lack of motivation

• Muscle weakness

• Increased irritability

• Needing more effort to complete everyday tasks

It can develop gradually and may affect people differently. Some feel constantly sleepy, while others experience a heavy, sluggish feeling without actually needing sleep. If your tiredness lasts for weeks or keeps returning, it may be worth looking deeper - especially if it starts interfering with daily life (NHS, 2023).

Tips for dealing with ongoing tiredness

Small lifestyle adjustments can make a real difference. You don’t need to overhaul everything at once - start with manageable steps.

Improve sleep habits

• Keep consistent sleep and wake times

• Avoid screens before bedtime

• Create a calm, dark sleep environment

• Limit caffeine in the afternoon and evening

Manage stress

Stress is one of the most common energy-drainers.

• Try relaxation techniques such as breathing exercises

• Schedule downtime

• Break tasks into smaller steps

Support your body with nutrition

Low energy is often linked to diet.

• Eat regularly

• Include iron-rich foods

• Prioritise protein and whole foods

• Stay hydrated

Move your body

Gentle, regular movement can increase energy rather than reduce it.

• Short walks

• Stretching

• Light strength exercises

Consistency matters more than intensity (Cleveland Clinic, 2023).

Possible causes of constant tiredness

Fatigue rarely has just one cause. It’s often a combination of factors.

Some of the most common include:

Poor sleep quality

Even if you sleep long enough, sleep disorders or irregular patterns can prevent proper recovery.

Stress and emotional strain

Chronic stress keeps your body in “alert mode”, which drains energy reserves.

Nutritional deficiencies

Low levels of iron, vitamin D, vitamin B12 or magnesium can contribute to fatigue.

Hormonal imbalances

Issues with thyroid function or other hormonal systems may affect metabolism and energy levels.

Underlying health conditions

Conditions such as anaemia, diabetes or chronic infections can lead to ongoing tiredness (MayoClinic, 2026).

Identifying the root cause is key - and this is where home testing can offer valuable insight. Services like Homed-IQ allow you to check important biomarkers from the comfort of your home.

Taking control of your energy levels

Feeling constantly tired can be frustrating, but it’s not something you have to simply accept.

Start by:

• Noticing patterns in your energy levels

• Making small lifestyle improvements

• Exploring potential biological causes

Home testing can help you understand what your body might be missing — whether it’s nutrients, hormonal balance or other markers.

If fatigue continues despite lifestyle changes, seeking further support is a smart next step. Understanding your body is the first step towards regaining your energy.

Frequently asked questions about fatigue

When should I worry about being tired all the time?

Occasional tiredness is normal. However, you should consider speaking to a healthcare professional if fatigue:

• Lasts more than a few weeks

• Worsens over time

• Comes with dizziness, breathlessness or weight changes

• Interferes with daily functioning

• Appears suddenly without a clear cause

Persistent fatigue can sometimes signal an underlying issue that deserves attention (HarvardHealth, 2021).

Can a home test help me find the cause of my fatigue?

Yes — in many cases, it can be a helpful starting point.

Home tests can measure things like:

• Iron levels

• Vitamin deficiencies

• Thyroid function

• Hormonal balance

With Homed-IQ, these tests are designed to be simple and accessible, helping you gather meaningful health insights without needing an immediate clinic visit.

While home testing isn’t a replacement for medical advice, it can provide valuable direction — helping you understand whether your tiredness may be linked to something measurable and manageable.
