Nutritional deficiencies, tight calf muscles or cold feet can all contribute to night time leg cramps.
Stretch your calf muscles before you go to sleep. This can be done by pulling your toes towards you when you're sitting on your bed.
Wearing socks at night can also help because cold feet will sometimes be a trigger.
The odd bar of soap trick - Interestingly, several readers of Dr. Peter Gott's medical column have noted that leaving a bar of soap under their bed sheet stopped their leg cramps. It seems odd, but it is cheap, safe, and easy to try - and has been working for folks! (I have no idea why.)
Recommended nutritional supplements:
- Potassium. This can be done by prescription or by eating a banana and/or drinking 12-16 oz (360-480 cc) of V8® or tomato juice daily.
- Calcium 500-1,200 mg at bedtime.
- Magnesium 200 mg plus B complex.
