sleeplessness

This means the body clock gets out of sync with the environment which can lead to sleeplessness, daytime tiredness and other issues.

One likely reason for Americans’ sleeplessness is cultural — a longstanding emphasis on industriousness and productivity.

Most people have experienced a night or two of sleeplessness, tossing and turning while being unable to fall asleep or stay asleep.

Troops who fired large numbers of artillery rounds or rockets dealt with sleeplessness, confusion and an inability to control their moods.

Those signs include giving away possessions, reduced appetite, sleeplessness and using the phrase “if I wasn’t here” in conversation.
