IT CAN BE A SIGN THAT YOU’RE NOT SLEEPING WELL
“There are two common reasons for morning headache,” says Dr Sean Tolhurst. “If you regularly wake up with a headache that disappears within 30 to 40 minutes of waking up, this can be a sign that carbon dioxide is building up in the body as you sleep which is caused by sleep apnoea – a condition that causes people stop breathing briefly many times a night. This type of headache must be checked out.”
A mild headache that doesn’t clear as quickly can be a sign of less advanced apnoea, or another sleep problem, as low level headache is a common sign of disturbed sleep. “Even a partner that snores can trigger this kind of headache,” says Dr Sean. If you can’t work out the cause yourself, ask your doctor about attending a sleep clinic.
