Fourth, higher quality maternal interactions have been shown to improve brain development at 5, 10 and 24 months.34 Fifth, there is growing evidence to suggest that the beneficial effects of exclusive breastfeeding may be moderated by the infant's genome, 35,36 and the metabolism of the fatty acids in maternal breast milk.37 For example, Krol et al. 36 showed that infants exclusively breastfed for a longer duration (above the 50th percentile) showed a heightened sensitivity and interest in a happy visual stimulus (eyes) than infants exclusively breastfed for a shorter duration (below the 50th percentile).

Physiologic studies have demonstrated that, in general, swaddling decreases startling, 301 increases sleep duration, and decreases spontaneous awakenings.310 Swaddling also decreases arousability (ie, increases cortical arousal thresholds) to a nasal pulsatile air - jet stimulus, especially in infants who are easily arousable when not swaddled but less so in infants who have high arousal thresholds when not swaddled.301 One study found decreased arousability in infants at 3 months of age who were not usually swaddled and then were swaddled but found no effect on arousability in routinely swaddled infants.301 In contrast, another group of investigators showed decreased arousal thresholds310 and increases in autonomic (subcortical) responses311 to an auditory stimulus when swaddled.

By using a lighter weight, higher repetitions, and varying the repetition duration, you can maintain the stimulus for a prolonged period of time and theoretically, you should be able to expend more energy than just pumping out a lower number of reps with high volume training.

This speech in fact serves as a preview of an upcoming report by my colleagues and I that takes this three pillar approach to analyze the clean energy policies of Germany, Spain and China, and makes the case that these countries are taking a comprehensive approach towards developing their clean energy industries, whereas all the United States has is a series of patchy and heterogeneous state action (e.g. state renewable energy standards) or federal action that is limited in duration (e.g. short - term renewable energy tax credits, or one - time green stimulus spending).

In terms of studies regarding behavioral problems, one extensive meta - analysis of the relationship between sleep deprivation and cognition in school - aged children found a significant increase in behavioral problems in children with shorter sleep duration.25) Additionally, sleep deprivation resulted in a significant increment in alertness and emotional reactivity in children, which led to delinquency, long - term emotional and behavioral difficulties.26 — 28) Consistent with such findings, sleep deprived subjects were more alert to negative stimuli, 29) and more susceptible to exaggerated aggressive impulses.30) Emotional lability and impulsivity were all strongly correlated with sleep deprivation, 31) with the severity of emotional dysregulation worsening as a function of the degree of sleep restriction.32)
