Here’s What Your Body Is Actually Trying to Tell You
You went to bed at a reasonable hour. You slept for eight hours. Your alarm went off and you lay there wondering how on earth you could still feel this tired.
We’ve all been there. The heavy limbs in the morning but not moving until mid-morning. A wall that falls at 3pm, like a door. Constant low level lassitude that isn’t cured by any amount of sleep. The small fear that lurks beneath everything: What’s wrong with me?
The solution is, in most cases, that nothing is wrong medically. The answer is that tiredness is a signal, and most are trying to turn the signal off, rather than read the message.
In the UK, one in five people feel unusually tired at any one time and one in ten have persistent tiredness, the NHS says. It’s not a side issue. It is a pandemic of fatigue that’s right under our noses.
Fortunately, most of the tiredness we experience in our daily lives can be helped with self-help. Real, scientifically based changes in sleep, food, exercise, and thinking habits, not a quick pill or drink. This guide takes you through 12 of the best self-help strategies to beat tiredness, explains why each is effective and provides you with something to do today.

Why Are You Actually Tired? The 5 Types of Fatigue Most People Don’t Know About
This is an area that most articles miss. And it is the element that makes everything else come together.
Fatigue is not a single entity. As with a broken arm, you can’t tell a person who’s emotionally drained that it’s time to go to sleep. It may be a bit of an aid, but it is not solving the problem. If you know what kind of fatigue you are facing, it can make all the difference in the world in how you go about solving it.
- Physical fatigue is the body’s reaction to over-training, illness or inadequate recovery following muscular activity. It’s not very responsive to rest, nutrition or sleep unless one is providing it between demands.
- Mental fatigue is what happens when the brain overexerts itself in decision making, problem solving, screen time and information overload. One of the most common forms of daily fatigue today and sleep alone does not cure it. The brain must be rested, not simply put to bed.
- Perhaps the most underdiagnosed is emotional fatigue. The negative effects of grief, strained relationships, long-term anxiety and caring for others without support are all subtly draining, and hard to spot on a blood test. Those with emotional fatigue sometimes say that they feel ‘tired in their bones’, even after a full night’s sleep.
- Sleep-quality fatigue is different from not getting enough hours. It is true that you can sleep for 9 hours and wake up exhausted if that sleep is poor quality; if you wake up more than once; or if you have an undiagnosed sleep condition such as sleep apnoea, which is interfering with your sleep.
- Medical fatigue is a tiredness resulting from underlying health issues, such as anaemia, hypothyroidism, vitamin deficiency, diabetes and more. This kind of tiredness cannot be cured by lifestyle changes alone — and is the kind that should be discussed with your GP if you are still getting tired after trying to do your best.
The vast majority of the self-help tips in this guide are applicable to all five types. However, understanding which category is the most relevant to your experience will help you prioritise on where to begin.
12 Self-Help Tips to Fight Tiredness That Actually Work
SLEEP QUALITY
1. Fix Your Sleep — Not Just the Hours
The biggest error people commit with sleep is to take it by the hour and give no thought to quality. Lacking eight hours of good sleep can make you feel more exhausted than after getting six hours of uninterrupted sleep.
Your body goes through 90 minute sleep cycles. If the alarm clock wakes you from the deepest sleep, you will have the same confused, drowsy feeling that will persist throughout the morning. If you are aiming to sleep, set your clock to sleep cycles, not hours.
Most people don’t realize how important the environment they sleep in is. A cooler room (around 16-18C), no screens at the bedroom and no light at all really aren’t optional extras for good sleep, these are the foundations. It also has strong parallels to the connection between insomnia and depression: both are linked to one another in a way that no amount of extra sleep or drug seems to be able to resolve, and even more alarmingly, sleep and depression both seem to promote one another.
Quick Win: Take your cell phone charger out of the bedroom tonight. A host of people are always amazed at the sleep improvement in 72 hours.
HYDRATION
2. Drink More Water — Dehydration Is Fatigue in Disguise
Dehydration is known to cause headaches by most people. Fewer realize that even 1-2% dehydration results in measurable fatigue, decreased concentration and poor physical performance, none of which you will experience before you feel thirsty.
Thirst is a late indicator. Your body usually begins to thirst before it is actually dehydrated. One of the easiest, most effective morning tiredness-fighting habits is to drink half a litre of water before any coffee.
Caffeine and alcohol are diuretics which work directly against you. If you’re using the same energy source to get up in the morning as you’re using to help you wind down at night, you could be feeding your fatigue in a vicious cycle. Water first. Coffee second.
Quick Win: Place a full glass of water on the table beside your bed tonight. Sip it first thing in the morning, tomorrow.
NUTRITION
3. Stop Eating for Energy Spikes and Start Eating for Sustained Energy
Sugar and refined carbs cause a rapid jump in blood sugar and a corresponding rapid drop. The afternoon droop at 2pm is more likely to be a direct result of lunch than of a lack of sleep.
The solution is not to eat less — it is to eat differently. Combining protein with complex carbohydrates slows glucose absorption, prevents the spike-and-crash cycle, and provides sustained energy for three to four hours. A chicken and brown rice meal keeps energy stable. A white bread sandwich with crisps does not.
Persistent tiredness can be a symptom of three basic nutritional deficiencies (first addressed in diet before supplements are recommended): Iron, B12, and magnesium. Most tired people are eating a lot of what they are missing – eggs, leafy greens, legumes and whole grains.
Quick Win: Tackle one ultra-processed snack for a portion of Greek yogurt and a handful of oats today. Be aware of your energy levels for the next 2 hours.
MOVEMENT
4. Move More to Feel Less Tired — Yes, Really
This one seems like an immediate contradiction when you’re feeling tired. The findings of the studies, however, are similar: moving about is one of the best natural ways to increase energy level, and sitting is one of the most consistent factors to cause chronic fatigue.
Walking for 20 minutes can boost energy levels for up to 2 hours post exercise. This is not a motivational statement – it’s a documented physiological reaction. Movement promotes blood flow, triggers endorphins, regulates cortisol to a proper daytime level and oxygen to the brain.
The common mistake made by the average tired person is to sleep the more they need to feel less tired; for the majority of fatigue related to lifestyle, more sleep is more fatigue. Unless you’re suffering from medical distress, the prescription is most often light, steady exercise, not sitting more horizontally.
Quick Win: If you’re feeling the afternoon slump, take a 10-minute walk instead of indulging in a cup of coffee. Notice the sensations 20 minutes after.
CAFFEINE
5. Fix Your Relationship with Caffeine
The mechanism of action of caffeine is that it blocks adenosine, the chemical which accumulates in your brain during the day and makes you drowsy. What most people don’t know, however, is that the half-life of caffeine is 5-7 hours.
That is, a cup of coffee at 3 p.m. will still contain 50 per cent of its caffeine level at 9 p.m. It isn’t always that it will prevent you from sleeping, but it certainly will interrupt your deep, restorative sleep, so that’s why you can have an afternoon coffee and fall asleep for 8 hours, then wake up feeling unrefreshed.
The one sleep hygiene change most people haven’t tried is the 2pm caffeine cut-off. When you’re truly exhausted, and depending on caffeine to get through the day, then it’s possible that the caffeine is keeping you fatigued, not alleviating it.
Quick Win: Give the 2pm rule a try for 5 days. It takes most people about a week before they feel a difference in quality of sleep and energy in the morning.
MENTAL LOAD
6. Reduce Decision Fatigue and Mental Overload
The cognitive resources you have available to you are limited and you use them on every decision you make, whether it’s what to eat for breakfast or what to do when you receive a challenging email. This is known as decision fatigue and is one of the subtler causes of fatigue that no one mentions.
Many people may feel exhausted by 6pm, even if they haven’t been doing any hard work, because they’ve made hundreds of little decisions throughout the day. The brain is truly fatigued similar to how a muscle becomes tired with repeated use.
This load will decrease only if intentional design takes place. Group similar activities into batches. Plan ahead the evening before (outfits, meals). Set up default answers for low stakes decisions so that brain power is saved for the matter at hand. Getting a brain dump Journal done before sleeping will significantly decrease mental chatter that many people struggle with, whether due to anxiety or staying awake.
Quick Win: Write down all thoughts and unfinished tasks that you have in your head before you go to bed tonight for 5 minutes. Just by externalising you will sleep better.
STRESS
7. Manage Stress Before It Manages You
Chronic stress is one of the most physically taxing ones that a body can be in. With a chronic activation of the stress response, your body operates on a higher level of cortisol – disrupting sleep, digestion, weakening the immune system, and consuming your body’s energy reserves.
The issue is that many stressed out individuals don’t feel like ‘stressed’. They feel stressed out, overwhelmed, or exhausted. The difference is important because stress fatigue can’t be fixed by more sleep, it must be real recovery. Not relaxation but activities that actively involve the Parasympathetic nervous system.
One of the quickest ways to get out of a stress response is to breathe slowly and with the diaphragm. The 4-7-8 technique (inhale for 4, hold for 7, exhale for 8) stimulates the vagus nerve and produces a measurable drop in cortisol in mere minutes. When combined with micro-recovery practices throughout the day – small moments of true stillness between tasks – the added impact on energy is huge.
Quick Win: When stress is rising, try slow, deep breathing (4 seconds in and 6 seconds out) the next time you notice it, for 2 minutes. Observe your energy change.
NUTRITION
8. Address Nutritional Deficiencies Quietly Draining Your Energy
The tiredness isn’t just the result of sleep and lifestyle changes, there is a type of tiredness that requires biochemical intervention. The four most common nutritional deficiencies that can cause fatigue are iron, vitamin D, vitamin B12 and magnesium, and all four are extremely common, especially among those who follow restrictive diets or live in areas with less sunlight!
Fatigue is caused by iron deficiency anaemia due to a decrease in the blood’s ability to transport oxygen to the muscles and organs. B12 deficiency can result in neurological symptoms such as brain fog, low mood and tiredness. Magnesium plays a role in more than 300 biochemical processes such as energy production and most people don’t get enough. The science linking vitamin D and energy is powerful; low vitamin D status is always linked with tiredness, depression, and a weak immune system, especially in the fall and winter.
If you have made sincere changes and if you still do feel tired, request your GP for a blood panel which includes these four markers. They’re rapid tests, easily treatable and frequently overlooked.
Quick Win: Get one handful of spinach (iron + magnesium) and two eggs (B12) and 15 minutes of sunshine (vitamin D) into your day. That is 4 deficiencies, addressed just on a very small scale and with little effort.
LIGHT & RHYTHM
9. Get More Natural Light — Especially in the Morning
Your body has a biological clock, called the circadian rhythm, which is a 24-hour cycle that controls your sleep, energy, mood, metabolism and hormones. Natural light in the morning is the most effective timepiece to set daily.
After waking, when exposed to natural light, there is a healthy level of cortisol awakening, a first hour response that creates a state of alertness, motivation, and energy for the rest of the day. The absence of the signal causes the biological clock to be off, and the energy flow of the day is reduced.
Light therapy lamps are lamps with a spectrum of natural sunlight that have been proven in several studies to enhance energy, mood and sleep quality in winter months or for those who commute in the dark. Just 10 minutes outside the door in the morning (without sunglasses) can make a difference in your alertness by 10am.
Quick Win: Get outside for 10 minutes after waking a maximum of 30 minutes later tomorrow morning. No sun glasses, no cell phone. It takes only light, air and a few minutes of rest.
REST
10. Power Napping: The Science of a 20-Minute Reset
Naps are not universally accepted as a good practice, despite all the scientific evidence. One study conducted by NASA concluded that a 26 minute nap could increase alertness by 54% and performance by 34% in individuals who had been sleep deprived. The concept is duration.
Naps of 20-26 minutes remain in Stage 2 sleep, which is the period of sleep that helps to improve alertness and motor function without inducing deep sleep. Longer naps take you into the slow-wave sleep, which when you wake up creates sleep inertia (the grogginess you feel after waking up caused by the slow-wave sleep) that makes you feel worse than when you fell asleep. Studies have also now found the ideal nap time that allows for the best recovery, which again proves that even shorter naps outperform longer naps.
An interesting thing to know about the caffeine nap is to have a coffee and then sleep right after it for 20 minutes. Absorbed in 20-30 minutes, the caffeine is absorbed when you need it most: at the beginning of the day, fully awake, not dazed. It sounds gimmicky. The study says no.
Quick Win: Timer for 20 minutes. Get on the bed without your cell phone. Even if you are not sleeping 100%, the rest is helpful, and it has a significant impact on reducing fatigue.
SOCIAL HEALTH
11. Check Who and What Is Draining Your Energy
Tiredness doesn’t always have to stem from within you. Some of it is coming from the environment and people around you. Emotional energy is not infinite — and it isn’t enough to sleep or eat it away, either.
This is a good time to sit with honesty. Do you have relationships in your life that regularly make you feel used up instead of energised? Do you end up watching the same videos or shows every night and get into a rut of doing the same things?
Living in the constant state of: the comparison, the outrage, the FOMO, keeps the stress response subtly on. It is not stressful. However, it does NOT allow the true recovery your nervous system requires between demands. One of the most overlooked energy investments you can make is to protect an hour of screen-free time every night.
Quick Win: See how you feel after an hour of scrolling through the phone. After 1 hour of reading, walking, or talking to someone you care about, notice how you feel. The data is right there!
ROUTINE
12. Build a Morning Routine That Generates Energy
Your neurological pattern for the day is set during the first 30 minutes of your day, affecting your energy, mood and focus for the rest of the day. Start them “reactively”, that is, with alarms, notifications and calls for immediate services and you begin the day in stress. Start them purposefully and the impact is real.
This does not need to involve waking up at 5am or an elaborate ritual. Three things are needed to be done regularly: No phone for the first 20 minutes, then some activity or natural light in the next 30 minutes, and water before coffee. That is it. Those three choices added up every day resulted in a noticeable change of the baseline energy within 2 weeks.
Making small changes in your lifestyle that have a significant impact is always the best way to begin – not to overhaul your lifestyle, not to make it perfect, but to make one intentional change over time and make it automatic.
Quick win: Make a decision tonight on what your first intentional action tomorrow morning will be. Have a glass of water next to your bed, your trainers by the door or your phone charger in another room. One thing. Then do it.
“Tiredness is not your personality. It is a signal. And signals can be answered.”
When Tiredness Is a Warning Sign — Not Just a Lifestyle Problem
For most of the common day-to-day, lifestyle-related fatigue, self help is effective. However, there are times when fatigue is a signal from your body that there is something that requires professional help — and it’s essential to know the difference.
Seek medical attention if tiredness continues for over 4 weeks after making realistic lifestyle changes. If it does not improve with better sleep, nutrition, regular exercise, and stress reduction, it is medically worthwhile to investigate the cause of fatigue.
If there is unexplained weight loss, if you are breathing faster than usual, if you have chest pain, if you are very tired, if you have been dizzy for a long time or if you have any other symptom that is unusual, seek medical attention early. The combinations may suggest conditions which need urgent investigation.
If you feel very tired after doing little or nothing, especially the following day, it may be a sign of chronic fatigue syndrome (ME/CFS), a recognised medical illness which is very different and requires specialist management.
Persistent low mood, loss of interest or emotional numbness can be a sign of depression. One of the most overlooked causes of fatigue is depression — and it should be treated as it is any other disease. It’s also one of the most curable. The relationship between depression and work performance and activities of daily living (ADLs) becomes clear when making the connections.
These warning signals that your body is sending you aren’t intended to alarm you — they are intended to help you. It’s not a sign of weakness when you need help. It is wisdom. [INTERNAL LINK 6]

Frequently Asked Questions
Q: Why am I always tired even when I get enough sleep?
There’s a distinction between the amount of sleep and the quality of sleep. Eight hours in the sack will still fail to give you the sleep you want, if you are not getting the 90-minute cycles, if your sleep environment is disturbing deep sleeping stages, or if you have stress and anxiety, and your nervous system remains active throughout the night. Other common causes of tiredness that will not be improved by sleep are dehydration, nutritional deficiencies, and uncontrolled stress.
Q: What vitamin deficiency causes tiredness and fatigue?
Iron, Vitamin D, Vitamin B12, and magnesium are the top four nutrients deficiencies linked to fatigue. Vitamin D is especially high in prevalence in the UK where there is a lack of sun exposure. Anaemia due to iron deficiency decreases the blood’s oxygen carrying capacity. Brain fog and fatigue are symptoms of B12 deficiency. The following are all simple tests that can be done in a GP surgery and are available to your GP:
Q: How can I boost my energy levels naturally?
The best evidence-based natural energy-boosters are a regular sleep schedule, natural sunlight in the morning, regular physical activity, proper fluid intake, eating a balanced diet of protein and complex carbohydrates, managing stress, and cutting back on caffeine after 2pm. None of these are sexy but they make a more significant and lasting change in energy than any supplement or stimulant.
Q: Is feeling tired all the time a sign of depression?
Fatigue is a very common but overlooked symptom of depression. Depression often comes in a variety of forms, not just sadness, but also as a lack of energy, motivation, clarity of mind, and feeling flat. Talk to your GP or a mental health professional is an important step if you’re feeling tired and having less interest in things you used to enjoy, feeling low or emotional numbness.
Q: What foods should I eat to fight tiredness?
Any foods that help us to avoid getting tired are the ones that help to stabilize blood sugar as well as providing key micronutrients: eggs (B12), leafy greens (iron, magnesium), oily fish (omega-3, vitamin D), whole grains (complex carbs, B vitamins), nuts and seeds (magnesium, healthy fats) and legumes (iron, fibre, protein). The avoidance of ultra-processed foods and refined sugars minimises the energy crash cycle which is a major cause of afternoon fatigue.
Energy Is Not Something You Find — It’s Something You Build
Fatigue is not who you are. It’s not the fact that you are the way you are or that you are built the way you are. It is a call — and a call can be responded to.
You don’t have to implement all 12 tips at the same time. Start with one. The one that stuck, the one that feels like it is attainable right now. It’s not a matter of willpower, it’s a matter of time: Consistent little actions create a real different energy baseline over time.
If twelve is too many, go back down to the 7-day plan and begin with Day 1. One glass of water. One night out of the bedroom with your cell phone. One 10-minute walk. It’s as simple as that.
