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. When an engine runs hot, the pistons swell. This reduces the clearance between the piston and cylinder walls. The cylinder bore can also distort adding to the problem.
When a thermostat sticks closed the engine will overheat. Overheating causes cylinder heads to expand greatly. This has the effect of crushing the cylinder head gasket and can crack the head[s]. Pistons also expand and gall the cylinder walls. Overheating, even for a short while can severely damage the engine.
