Prevention is always the best medicine with sleep problems. A comfortable sleeping area is a prime consideration to sustained deep sleep. Both noise and light can easily cause awakening; if outside noise and light can’t be completely eliminated then ear plugs and eye shades should be considered.
The average person turns over more than 40 times a night so if you are waking up due to a sore back, then consider that your mattress may not suit you and you should shop around for one more appropriate to your spine. For the same reason, sleeping with another person can cause awakening due to movement, especially if he or she is also a loud snorer. There’s something to be said for separate beds and, perhaps, separate bedrooms in these cases.
Restless leg syndrome can dramatically amplify night movements that lead to interrupted sleep. Taking a calcium/magnesium supplement before bed will often stop or reduce these aggravating complaints. A homeopathic remedy called magnesia phosphorica will sometimes work faster than calcium/magnesium if needed in the night.
A common factor in interrupted sleep is taking unresolved business to bed. Your subconscious will be working on sorting and solving these issues; if something wakes you, your brain will bring the processing of these issues to your conscious mind, and perhaps not let you back to sleep while the problem-solving is taking place.
A good idea is to have a pen and paper by your bedside to jot down the resolutions achieved, so your mind doesn’t have to keep replaying them over and over again to the detriment of your sleep. Perhaps jotting everything down before bed will even prevent the need for awakening in the night.
