Having tense neck muscles can cause headaches. Muscle tension can be exacerbated by having pillows at the wrong height, having too many pillows, having poor posture or working with your computer set up at the wrong height.

Top Tip: If you find that you are holding tension in your neck try adjusting your working environment so that you’re not squinting at your monitor or holding your neck at a weird angle and check how your spine feels when you’ve got your head on your pillows.

Having regular massages or reflexology treatments can help reduce muscle tension.

Causes of headaches: Stress

Stress can be a big contributing factor to headaches. As you will know if you’ve ever been truly stressed, it can be impossible to think straight whilst your body is in fight, flight, freeze mode. Your body will start to shut down any unnecessary processes making it hard to sleep or eat properly.

This can all bring on a headache. If you are getting lots of headaches stress may be the cause.

Top Tip:
Try listening to calming music, meditations or podcasts, do some deep breathing exercises or take a yoga class.

Cause of headaches: Too much or too little caffeine

If you are used to drinking a lot of caffeine, suddenly reducing your caffeine intake is likely to bring on a headache.

That said, having too much caffeine can also bring on a headache.

Some people drink coffee more at work than at home (or vice versa) and suddenly changing may result in a headache.

Hangovers can cause headaches due to dehydration. Your body will be working harder to process the alcohol. Alcohol is notorious for disturbing both your sleep patterns and your mood and may leave you feeling hungry.

Drink plenty of water before bed and eat a light snack. Try to eat and drink something if you can when you wake up.

What causes headaches hormonal fluctuations

Cause of headache: Hormonal Factors.

Fluctuating hormones can cause headaches. Many menstruating women notice that they have a headache when oestrogen levels dip in the last 2 or 3 days of one cycle and the first 2-3 days of the next.

If you’re finding that you have a headache from day 26 – day 3 of your period, hormones could well be a factor.

Headaches are also common during perimenopause (the run up to the menopause) and during the first trimester of pregnancy.

If you are in your second or third trimester of pregnancy and have a sudden, severe, headache please get urgent medical help

If you are taking any medication whether prescribed or over the counter, double check if the side effects include headaches. The contraceptive pill can also give you a headache.

Top Tip:
If you think your headaches are linked to your medication/contraception speak to your doctor for a treatment review.

What causes headaches holidays

Causes of Headaches: Sudden changes in lifestyle, holidays, weekends etc

Do you find that the minute you stop work or have a holiday you get a headache? This could be caused by a sudden change in lifestyle.

Chances are if you’re on holiday you will have had the anticipation of the holiday, the stress of packing, the panic about missing a flight or not finding the hotel etc.

Then suddenly you relax and then the headache comes. This can also be linked to changes in eating and sleeping patterns, drinking more or less caffeine and alcohol, heat, etc. 

Top Tip: Try taking your foot off the pedal slowly in the run up to your holiday and try to keep some semblance of a routine. Keep hydrated and have regular meals.

Try to get up and go to bed at the same time every night and eat meals at similar times so your body knows what to expect.
