Tiredness

If you practice a healthy lifestyle and better sleeping habits but still find yourself suffering from daytime drowsiness, it may be a sign of a more severe medical condition such as: obstructive sleep apnoea (OSA), anaemia, thyroid problems, narcolepsy, depression, restless leg syndrome, undiagnosed heart disease, or deficiencies in key nutrients. If you think that you may be suffering from one of these medical conditions you should contact your sleep physician immediately.
