For these reasons, healthy levels of magnesium have been linked to deep, undisturbed sleep. Consequently, low levels of magnesium can contribute to frequent nighttime wakings. Magnesium deficiency has been linked to several insomnia-inducing conditions, including restless leg syndrome (RLS) and night terrors.
Scuffing is another condition that can damage pistons. Scuffing is often the result of overheating, but loss of lubrication, detonation and preignition can also be contributing factors.
