As expected, findings from such EMA studies of alcohol-related problems generally suggest that heavier levels of consumption on a given night are associated with experiencing more alcohol-related problems that night (Dvorak et al., 2014; Simons et al. 2005, 2010).
Discharge in the evening and at night was associated with higher crude hospital mortality compared with day (evening OR 1.37, 95% CI 1.32 1.43; night OR 1.47 95% CI 1.34 1.61), which was still significant after adjusting for case mix (evening OR 1.22, 95% CI 1.16 1.28; night OR 1.34, 95% CI 1.20 1.50).
A recent study in the journal Sleep showed that sleeping fewer than five hours or more than 10 hours a night is associated with staying home sick for 4.6 to 8.9 more days than people who sleep between seven and eight hours a night.
On a night typically associated with feel-good humor, there was an undercurrent of tension.
Among children, sleeping less than 10 hours a night is associated with weight gain.
THE BOTTOM LINE -- Averaging more than seven hours of sleep a night is associated with a shorter life span, though whether poor health or too much sleep accounts for the link is unclear.
A study of 7-year-olds has found that sleeping less than nine hours a night was associated with being overweight or obese, even after accounting for amounts of television watching and physical exercise.
In 2002 American researchers analysed data from more than one million people, and found that getting less than six hours sleep a night was associated with an early demise – as was getting over eight hours.
The most important of these phenomena are: the equatorial electrojet (EEJ) current system and its instabilities, the equatorial ionization anomaly (EIA), and the plasma instabilities/irregularities of the night ionosphere (associated with the plasma bubble events – ESF).
Neither the day (weekday vs weekend) of admission into ICU nor the shift work (day vs night) were associated with ED length of stay; weekday 276 minutes vs. weekend 288 minutes, Figure 3 ED time and diagnosis in ICU admission.
Abnormal circadian rhythms, including exposure to light at night, are associated with a higher cancer risk and a poorer prognosis [3] [7], which may be one of the reasons that the incidence of cancer is increasing in individuals subjected to these stresses.
