    i have common headaches and up until now i still cannot tell the reason for it. even the doctors i believe cannot tell outright if it is stress headache, migraine, sinus, eye-strain…or whatever else.

    i just try to do whatever i think i should to avoid recurrence. but well, it still comes.

  • Sleep deprivation is linked to migranes. Treatments that reduce stress are beneficial in preventing migraines, and certain essential oils such as lavender, rosemary and eucalyptus are promoted for relaxation. Snoring is also one of the reason for sleep deprivation. There are many problems that can be the result of having Snoring. Snoring is a very common sleep issue that keeps a lot of people from getting the proper rest they need. A lack of sleep can be problematic, leaving you feel tired and sluggish all day.
