According to a new study, relying on caffeine to help you through your day can only get you so far.
Caffeine may help you stay awake to attend to a task, but it doesn't help to prevent procedural errors that can cause, for example, medical mistakes and car accidents.
The study investigated the effect of caffeine on the completion of simple tasks as well as place-keeping tasks - tasks that need to be completed in a specific order without skipping or repeating steps.
The study looked at the effect of caffeine after a period of sleep deprivation.
We often see similar facial appearances of family members in photo albums, observing how genes determine certain distinctive features in our bodies.
In-depth genetic knowledge and how our DNA is linked to facial appearance is a relatively new accomplishment by geneticists. 130 chromosomal regions which are associated with our facial shapes and features have been identified, in a comprehensive process involving scanning the DNA of 8000 participants.
One calorie (kcal) = 4.18 kJ
To convert from calories to kJ, multiply calories by 4.18.
For example, a medium-sized banana (118 grams) provides 105 calories (kcal). 105 x 4.18 = 439 kJ.
The term kilocalorie (kilo meaning 1,000) was created to refer to a large calorie. The term small calorie is only used in physics and chemistry research.
This means that with nutrition, the terms calories and kcal equal the same amount of energy (1 kilokalorie = 1 calorie in nutrition.)
Calories are the amount of energy in foods and beverages, or the amount of energy you burn exercising.
Energy is measured in Kilocalories (kcal) and kilojoules (kJ). If you're counting calories or comparing the calorie contents of foods, this can cause confusion.
Calories can be small or large.
This means that 1 large calorie = 1,000 small calories, as 1 kg = 1,000 grams.
The PNS's primary role is to connect the CNS to the organs, limbs, and skin. The peripheral nervous system is divided into two parts:
The autonomic system controls aspects of the body that are usually not under voluntary control. The autonomic system is divided into two branches:
The somatic system is responsible for transmitting sensory information as well as voluntary movement. The system contains two major types of neurons:
