Tips for getting a better nights sleep

  1. You should aim for 8 hours sleep per night – if you lose track of time at night and end up binge watching box sets you could set an alarm for bedtime too. 
  2. An essential sleep hormone called melatonin loves darkness, it is often called the vampire hormone so try dimming your lights in your house.  Keep your room in darkness, use black out blinds or a sleep mask.
  3. No screen time an hour before bed – looking at your IPAD and phone screens before bed seriously reduces your melatonin levels. 
  4. No caffeine after 12pm.  Caffeine has a ½ life of 6 hours and a ¼ life of 12 hours so this means that if you have a cup of coffee at midday it is like drinking a ¼ cup of coffee at midnight and expecting a good restful nights sleep….
  5. Alcohol will not help you sleep – it causes a disturbed sleep so you don’t wake feeling restored.  It also blocks your rem sleep which is so important.
  6. Temperature is important for a great nights sleep so make sure that your bedroom isn’t too hot or too cold.  Optimum temp is 18 degrees.  Your body temperature needs to drop by about 2 degrees for good sleep.  This is why having a hot bath before bed works so well, its not just the relaxation but the way that your body cools down when you get out.
