For “blue blocking” glasses or amber lighting in the early evening until you go to bed, I recommended the UK supplier https://www.blockbluelight.co.uk or in the USA: https://www.somnilight.com
Bright Light Box
A bright light box providing 10,000 lux for 30 mins, first thing in the morning for example when you have breakfast or read the paper can help treat seasonal or non-seasonal depression.
In the UK, Lumie is a good supplier but whoever you choose check the distance from the light box to obtain 10,000 lux. It is usually 30cm but this may be less in smaller models. Optimise the timing of the bright light by completing this questionnaire.
Consider a dawn simulator as your alarm clock e.g. Lumie Dawn Simulator or Philips. It is very pleasant way of waking in the morning. The cost will depend on how many extras you want such as analogue or digital radio.
Consider replacing an uncomfortable mattress if you can. See here.
Working shifts on can be disruptive to your sleep pattern. Advice from the Sleep council on shifts is here.
If you notice a distinctive pattern of snoring in your partner, find out about sleep apnoea here. It can be dangerous if left untreated.
