Poor diet, lack of exercise, and inadequate sleep can all contribute to feeling unwell, which can worsen malaise. Our bodies need balanced nutrition, regular physical activity, proper hydration, and adequate sleep to function properly.
Below are some common reasons why someone might feel sick, plus their symptoms and how to treat each.
Two crucial symptoms you should never ignore are sudden, severe headaches (like "the worst headache of your life") and sudden weakness, numbness, or slurred speech on one side of the body, as these can signal a stroke or brain issue, requiring immediate medical help. Other critical signs include chest pain, shortness of breath, unexplained weight loss, and persistent confusion or changes in bowel habits, all pointing to potentially serious underlying conditions.
Medications: Malaise can be a side effect of both prescription medications and nonmedical drugs. Metabolic conditions: You might experience malaise during blood sugar highs and lows. Mental health conditions: Common mental health issues like anxiety and depression can cause vague symptoms like malaise.

Vitamins that Can Boost Your Mood
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.
Sudden or severe dizziness, confusion and/or clumsiness
The important words here are “sudden” or “severe.” If any of these symptoms come on suddenly or are severe, call 911 or head to an ER: Clumsiness, loss of balance or fainting. Difficulty speaking or trouble understanding speech.
Physical signs of stress
Five key signs your brain might be in trouble include significant memory loss (forgetting important things or familiar routines), difficulty with everyday tasks, confusion about time/place, problems with language/communication, and noticeable personality or mood changes, such as increased irritability or loss of interest in hobbies, which signal potential cognitive decline or neurological issues.
Symptoms
The 40s and 50s
Both fluctuations can result in lower energy levels, feeling lethargic, and less muscle mass. Again, the 40s and 50s impact people differently, with some noticing fewer effects than others. However, during this stage, people will usually notice they're "getting old".
When your doctor can't diagnose you, it may help to ask questions about additional testing, seek a referral to a specialist, or get a second opinion. Failure to get an accurate diagnosis can delay treatment and potentially worsen your condition.
Vitamin D and omega-3 fatty acids work together in several ways to fight depression, mainly through reducing inflammation and balancing brain chemicals. When we talk about brain chemicals, serotonin is the most important one in depression.
Low dopamine symptoms often involve a lack of motivation, pleasure (anhedonia), and energy, leading to fatigue, mood changes like depression/anxiety, difficulty concentrating, and a reduced sex drive, alongside physical issues such as sleep problems, muscle stiffness, tremors, and slow movement (like in Parkinson's).
Taking steps to improve physical health can help boost mood and ward off depression. For example, many types of exercise have mood-boosting benefits, especially if they involve being outdoors. Try walking, playing a team sport or pumping iron at the gym.
