Two of the largest ligaments of the wrist are the medial (ulnar) and lateral (radial) collateral ligaments. The MCL passes from the distal end of the ulnar and crosses the wrist to attach to the triquetrum and the pisiform. The LCL passes from the end of the radius, across the joint to the scaphoid.
One of these can be dehydration. Most people in Britain don't drink as much fluid as they need for optimum health.

1 Snooze Foods and Pick-Me-Ups Certain foods contain an amino acid called tryptophan that causes sleepiness. 2  Carbohydrates make tryptophan more available to the brain, which is why carbohydrate-heavy meals can make you drowsy. It is made in the brain by converting tryptophan first to serotonin and then to melatonin, which is secreted at night by the pineal gland in the brain to induce and maintain sleep. 2  Scientific evidence shows little or no benefit of melatonin in improving sleep.
