In other cases, such as with a tension headache where the muscles are too tight, a warm compress may help relax these muscles and bring relief.
A warm compress could be as simple as a heated towel. People may be able to get the same effect from a tepid shower or bath.
In some cases, there is a physical reason for a headache. Check for anything that is putting too much pressure on the head. This may be a ponytail or bun that is too tight or a hat or headband that has been on too long.
