Yes, it's normal to tire more easily as you age, but feeling constantly exhausted isn't normal and often signals an underlying issue like sleep problems, medications, anemia, depression, or chronic conditions (heart/diabetes) that need a doctor's attention, as fatigue can impact health and daily life significantly. While some sleep changes (sleeping earlier/lighter) are normal, persistent tiredness means investigating causes like sleep apnea, nutrient deficiencies, anxiety/grief, or medication side effects, requiring a medical check-up.
When you or your parent is 50, 70, or 87 years old, there may be a pervasive weariness that is hard to shake. While it's common to experience tiredness in old age, ongoing or severe fatigue can indicate an underlying health issue that needs to be evaluated and monitored carefully by a specialist and a care team.
Making changes to your lifestyle may help you feel less tired, for example:
Less physical activity in older age, known as deconditioning, leads to muscle loss, weakness, and tiredness. Sleep cycles change with age, and regular sleep disruptions result in lower energy. Lower levels of hydration are common among older adults, and chronic dehydration often causes fatigue.
Fatigue red flags signal potentially serious issues beyond normal tiredness, including unexplained weight loss, persistent fever, night sweats, shortness of breath, chest pain, severe headaches, confusion, or new neurological/joint problems alongside exhaustion. Other signs include fatigue worsening with activity, significant cognitive/mood changes, or lack of energy despite rest, suggesting conditions like infection, autoimmune disease, heart problems, cancer, or mental health issues, warranting prompt medical evaluation.
Vitamin and mineral deficiencies, including B2, B3, B5, B6, B9, B12, C, D, iron, and magnesium, are among the most common causes of unexplained fatigue. Vitamin D deficiencies affect over 50% of the global population, and approximately 12.5% have iron deficiency anemia.
In six months before death, patients show a number of physical and mental changes. Some of the most common changes include progressive fatigue, loss of appetite, emaciation, and social withdrawal. Also, some patients lose some memory and other cognitive changes.
“… relatively little decline in performance occurs until people are about 50 years old.” (Albert & Heaton, 1988). “… cognitive abilities generally remain stable throughout adult life until around age sixty.” (Plassman, et al., 1995)
Older adults need about the same amount of sleep as all adults — seven to nine hours each night. But older people tend to go to sleep earlier and get up earlier than they did when they were younger. Getting enough sleep helps you stay healthy and alert.
A balanced daily routine might include: Physical activity: Gentle exercise like walking, stretching, or yoga supports mobility, strength, and heart health. Mental stimulation: Reading, puzzles, learning a new skill, or engaging in hobbies keeps the brain sharp.
The number one exercise for older adults is often cited as the squat, especially bodyweight or chair squats, because it builds essential leg strength for daily function, balance, and fall prevention, directly improving independence. However, a well-rounded routine also needs balance work (like Tai Chi), cardiovascular exercise (walking, swimming), and other strength training (resistance bands, push-ups) for overall health, as experts emphasize functional movement and power.
10 Things Draining Your Energy
What Does Sleep Look Like in Older Adults? According to their internal body clock, most older adults need to go to sleep around 7 p.m. or 8 p.m. and wake up at 3 a.m. or 4 a.m. Many people fight their natural inclination to sleep and choose to go to bed several hours later instead.
Signs you're aging well include physical vitality (easy movement, good balance, strength for daily tasks), sharp cognitive function (curiosity, learning new skills, remembering details), and strong emotional/social health (staying connected, finding purpose, managing stress). It's about maintaining independence, a positive mindset, and actively engaging in activities you enjoy, not just looking younger, though good skin/hair can be indicators too.

The "2-finger test" for dementia involves an examiner showing a hand gesture (like interlocking index and middle fingers) and asking the patient to copy it, testing motor skills, visual memory, and coordination, as difficulties can signal early cognitive decline, but it's a screening tool, not a definitive diagnosis, prompting further medical evaluation. Other related tests include finger-tapping and finger-to-nose, looking for hesitation or misjudgment in movement.
You Miss Out on Sleep
You do a few things you know you shouldn't -- we all do. But some of those bad habits can take a toll on your brain. For example, lack of sleep may be a cause of dementia, including Alzheimer's disease. It's best to have regular sleeping hours.
Signs of memory loss as a part of normal aging
You're unable to remember details of a conversation or event that took place a year ago. You're unable to remember the name of an acquaintance. You forget things and events occasionally. You occasionally have difficulty finding words.
A Few Months Before Death
At first, usually over a period of 1–3 months, your loved one is likely to: Feel weak and become less active. Sleep or doze more. Eat and drink less, often preferring soft foods.
Some common early signs include a significant decline in energy levels, decreased appetite, weight loss, increased sleeping, withdrawal from social activities, and a decline in cognitive function.
The fear studies show that children's fears can be grouped into five categories. One of these categories is death and danger. This response was found amongst children age 4 to 6 on the KFQ, and from age 7 to 10. Death is the most commonly feared item and remains the most commonly feared item throughout adolescence.
The right combination of vitamins can address both types of low energy levels. Certain vitamins like B12, iron, magnesium and Vitamin D directly impact parts of the energy production cycle. Deficiencies in these vitamins can cause symptoms like fatigue, weakness and low energy.
Taking too much vitamin D leads to calcium buildup (hypercalcemia), causing physical signs like nausea/vomiting, fatigue/weakness, frequent urination & excessive thirst, constipation, and confusion/disorientation, alongside potential bone pain or kidney stones, often from supplements, not sun exposure.
Symptoms of vitamin B12 or folate deficiency anaemia
Anaemia is where you have fewer red blood cells than normal or you have an abnormally low amount of a substance called haemoglobin in each red blood cell. General symptoms of anaemia may include: extreme tiredness (fatigue) lack of energy (lethargy)
