I eat well and sleep for 7 – 8 hours. Why do I still feel tired?

There can be several reasons to feel tired even after sleeping well. 

Health conditions such as Adrenal Fatigue and Chronic fatigue syndrome are conditions in which this can occur. In adrenal fatigue, prolonged exposure to stress could drain the adrenals leading to a low cortisol state, leading to tiredness. Chronic fatigue syndrome (CFS) is a complicated disorder characterised by extreme fatigue that lasts for at least six months and the underlying medical condition is still not clear. It can be due to viral infection, psychological stress, or a combination of factors.

Another reason could be thyroid disease. Due to an underactive thyroid (hypothyroidism), the body’s metabolism slows down and can lead to many symptoms, including lethargy and fatigue.

Inconsistent sleep also factors in this. Deprived quality of sleep, waking up irregularly, and improper daytime sleepiness make you feel tired throughout the day.

The irregular sleep-wake syndrome can lead to insomnia and drowsiness throughout the day leading to fatigue. In it, there is a near absence of the circadian rhythm responsible for regulating periods of wakefulness and rest.

Other reasons can be anemia, dehydration, and following a sedentary lifestyle.
