Is poor sleep affecting your work and lifestyle?



It’s not unusual to have difficulty sleeping from time to time, but when it becomes a habit, you should seek professional help. Sleep deprivation can have a negative impact on how you function at work and home.

It’s possible that we become so anxious to get to sleep when we haven’t slept well for a few nights, the anxiety keeps us awake. Sleep anxiety can be reduced by accepting that waking up is normal and re-framing your thoughts. Relaxation exercises may help too.

Sleep Apnoea

Sleep apnoea occurs when the walls of the mouth and throat close during sleep. This reduces the oxygen flow to the body. Listening to someone snore and breathe can help you identify sleep apnoea. They may have short pauses lasting a few seconds or minutes. After a minute, the person will snore and gasp. They may also briefly wake up as they struggle to breath. The associated fatigue during the day can be dangerous if sleep apnoea is not treated promptly.


Sleep disturbances are caused by menopausal symptoms such as night sweats and hot flushes. Our body temperature must drop to fall asleep and remain asleep. You can prepare strategies that will help you cool off quickly so you can get back to bed if you are too hot. You can keep a fan or a bowl of ice water in your bedroom.

Delayed Sleep Phase Syndrome

Melatonin, the sleep hormone, must rise in order to make us feel sleepy. Some people’s levels of melatonin do not rise until later in the evening, which makes it hard to fall asleep before midnight.

Advanced Sleep Phase Syndrome

It is similar to the previous problem, except the person feels sleepy in the early evenings, sometimes even before six. It may cause them to awaken in the wee hours of the night and not be able to fall back asleep.

Restless Legs Syndrome

This syndrome can cause uncomfortable sensations to occur in the arms and legs. These sensations can be described as prickly, painful, crawling or tingling. They may also cause an uncontrollable urge to move your legs. Self-help methods and medications may be used to treat this problem.

Periodic Limb Motions in Sleep

Involuntary leg movements can be caused by periodic limb movements during sleep, such as flexing toes, bending knees or hip twitching. It can disrupt the sleep of a person who has PLMS, or anyone else sharing the bed. It can sometimes be treated with a reduction in alcohol, caffeine or smoking as well as certain medications.

Sleep problems can be treated by seeking help.

You should seek the help of your GP if you have been experiencing sleepless nights over a period longer than a couple weeks, or relying on sleeping pills to sleep for more than two weeks. Your doctor may offer advice or refer you to an expert sleep specialist or psychologist depending on the issue.
