Each additional 30 minutes a day of light intensity activity, such as gentle gardening or taking the dog for a walk, for example, was associated with a 17 percent reduction in the risk of death.
The comments come after they found that even just a few minutes at a time of any level of physical activity, including of light intensity, is linked to a lower risk of death in older men.
The authors concluded: "[These] findings could refine physical activity guidelines and make them more achievable for older adults with low activity levels: stressing the benefits of all activities, however modest, from light intensity upwards; second, encouraging accumulating activity of all intensities without the need to sustain bouts of 10 min or more.
2015), while an inadequate light intensity can be stressful to fish and even lead to mortalities (Boeuf & Le Baile, 1999).
In addition the light intensity is an important factor affecting the growth and lipid accumulation, and it could also affect fatty acid composition in the microalgae Parietochloris incise and Dunaliella viridis [18].
1988) found that no influence of light intensity (LI) (180 vs 6 lux) on BW.
935 and the effects of temperature, dye concentration, reaction time, UV light intensity and pre-treatment methods on its photocatalytic activity have been firstly presented.
0 lux (beginning from onset of scotophase to onset of photophase), measured with a TES model 1330A illumination meter (TES Electrical Electronic Corp, Taipei, Taiwan), were used instead of scotophase to evaluate the impacts of light intensity on sexual behavior in H.
Moderate exercise strengthens the heart, muscles, and bones, and confers health benefits that low and light intensity activities can't.
In our study, effects of body size and light intensity on swimming and schooling behaviors of juvenile white rockfish were examined under laboratory conditions.
VLC normally involves the transmission of data through modulations of LED light intensity that occur faster than the persistence of the human eye.
Building on the more than 17000 mW/cm2 light intensity (at 300-450nm), DYMAX have added an automatic power-on sequence which ensures full light output before the unit can be used, so preventing partial cures in early throughput.
