Wake-up Call: Fight Fatigue at Its Roots

Are these ordinary signs of aging? Exhausted throughout the day, joy in life slowly diminishing, active lifestyle becoming a distant memory. No, no and no. Feeling tired all the time is not a normal part of the aging process. Instead, it can point to the need for a better night’s sleep, stress or an underlying illness, or be the result of a mix of common medications. Or it may be a combination of all these things. Identifying the possible sources of your fatigue is the most important step in reenergizing your lifestyle.

Medical: Visit your physician to rule out these frequently seen causes of tiredness.

Emotional health: Low-grade depression, anxiety or chronic stress can sap energy.

Anemia: This condition occurs when your blood has too few red blood cells or those cells have too little hemoglobin, a protein that transports oxygen through the bloodstream. If untreated, anemia results in a drop in energy levels.

Heart disease: When the heart pumps blood less efficiently, it can lead to fluid in the lungs, causing shortness of breath and reducing the oxygen supply to heart and lungs.

Hypothyroidism : An underactive thyroid gland can cause fatigue – along with other symptoms, such as weight gain, weakness, dry skin, feeling cold and constipation.

Medications : Many medicines can cause fatigue, including blood pressure drugs, antidepressants, anti-anxiety drugs and antihistamines.

Lifestyle Habits

Sleep: Quality, quantity and environment matter greatly in ensuring a healthy sleep, but these factors are surprisingly misconstrued. According to NYU School of Medicine, dispelling these widely held beliefs is key:

Myth: “Alcohol before bed is good for sleeping.” A nightcap before bed may help you fall asleep but will dramatically reduce the quality of sleep by disrupting the REM (rapid eye movement) stage all night, and you’ll wake unrefreshed.
Myth: “Many adults need only five hours of sleep or less, especially as they get older.” The reality is everyone needs to get enough sleep to wake up feeling refreshed. The average is seven to eight hours nightly to allow the body to progress through four phases of restorative sleep, including deep sleep cycles of REM and delta waves sleep, which are important for generating neurons, repairing muscle and restoring the immune system.
Myth: “Watching TV in bed before sleep is a good way to relax.” Actually, turning off the TV and putting away electronic devices at least two hours before bedtime is recommended, as the blue light produced affects the release of melatonin, the sleep hormone, and will delay slumber.
Myth: “If I wake up in the middle of the night, it is best to lie in bed until I fall back asleep.” Tossing and turning for more than 20 minutes is not helpful; instead, change rooms and engage in something mindless, like folding socks. Do not watch TV or look at electronic devices, as this wakes up your brain.
Myth: “Snoring is a common, harmless problem.” Snoring can be a sign of sleep apnea, a disorder characterized by decreased or complete lack of airflow throughout the night. Over time, this can increase the risk of cardiovascular disease if untreated.
Myth: “Falling asleep anywhere, anytime is the sign of a good sleeper.” It’s just the opposite, indicating a sleep “debt” from insufficient rest or a sleep disorder such as narcolepsy or sleep apnea.

Under- or over-activity: Sedentary days and nights can cause loss of muscle mass and flexibility and make even moderately intense activities seem exhausting. However, exercising at a very high intensity can also cause fatigue.

An Infusion of Energy for Chronic Fatigue Research

Far beyond ordinary tiredness is the profound fatigue known as myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS), which has puzzled and frustrated medical professionals for decades. No cure or approved treatment is available to its 2.5 million sufferers, only a management of symptoms worsened by any type of physical, cognitive or emotional effort. But a sea change is underway. It began in 2015 with a new name recommendation by the Institute of Medicine (IOM): Systemic Exertion Intolerance Disease (SEID). Noting that the term chronic fatigue syndrome can trivialize the seriousness of the condition and that “ME” is inappropriate because neither muscle pain nor brain inflammation has proven to be a symptom, the IOM panel stated: “SEID captures a central characteristic of this disease – that exertion of any sort can adversely affect patients in many organ systems and in many aspects of their lives.”

Even more promising is the significant investment in research announced by the National Institutes of Health (NIH). Up to $36 million over five years has been granted to shine a brighter light on the origins and progression of chronic fatigue and ultimately to help develop diagnostic markers and effective treatments.
