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. Although, over time, they may inadvertently train themselves not to feel thirsty, the suppressed desire to drink can result in restlessness and a host of minor problems that make sleep difficulties worse.
And the current review suggests that itâs the amount of alcohol people drink that may have the biggest effect on their sleep quality. One or two drinks, for example, can increase slow-wave sleep while not affecting deeper REM sleep. But more alcohol can cut into the time spent in the REM stage. So that nightcap may be helpful in getting you to doze off, while a wild night of heavy drinking is likely to make you more restless. Moderation, it seems, is the key to a good nightâs sleep.
