Women who conceive during the first few months of the year are more at risk of postnatal depression, a study has found.

Those who enter their final trimester during ‘short’ daylight hours are 29 per cent more likely to suffer from the mental-health condition.

In the northern hemisphere, this runs from August to early November. 

Sunlight is thought to trigger the production of the hormone serotonin, which boosts a person’s mood and helps them feel calm.

The researchers at San José State University analysed two studies with a total of 293 women.

These trials investigated the amount of daylight the women were exposed to during the last trimester of their pregnancies.

All of the participants were first-time mothers from California. 

Results, published in the Journal of Behavioral Medicine, suggest pregnant women have a 30 per cent risk of developing postnatal depression overall.

This risk falls to just 26 per cent among those who are in their third trimesters during the ‘long’ daylight hours.

Women who are in their final stage of pregnancy between August and early November – ‘short’ days – are the most at risk, with a 35 percent chance of suffering from postnatal depression.

WHAT IS POSTNATAL DEPRESSION?

Postnatal depression is a form of the mental-health condition that affects more than one in 10 women in the UK and US within a year of giving birth.

As many men can be affected as women, research suggests.  

Many parents feel down, teary and anxious within the first two weeks of having a child, which is often called the ‘baby blues’.

But if symptoms start later or last longer, they may be suffering from postnatal depression.

Postnatal depression is just as serious as others form of the mental-health disorder. 

Symptoms include:

  • Persistent sadness
  • Lack of enjoyment or interest in the wider world
  • Fatigue
  • Insomnia
  • Struggling to bond with your baby
  • Withdrawing from others
  • Difficulty concentrating and making decisions
  • Frightening thoughts, such as hurting your baby

Sufferers should not wait for their symptoms to just go away.

Instead they should recognise that it is not their fault they are depressed and it does not make them a bad parent.

If you or your partner may be suffering, talk to your GP or health visitor.

Treatments can include self-help, such as talking to loved ones, resting when you can and making time to do things you enjoy. Therapy may also be prescribed. 

In severe cases where other options have not helped, antidepressants may be recommended. Doctors will prescribe ones that are safe to take while breastfeeding.

Postnatal depression’s cause is unclear, however, it is more common in those with a history of mental-health problems. 

Lack of support from loved ones, a poor relationship with the partner and a life-changing event, such as bereavement, can also raise the risk.

These women’s symptoms are also more severe if the condition does develop.

‘Among first-time mothers, the length of day in the third trimester, specifically day lengths that are shortening compared to day lengths that are short, long or lengthening, were associated with concurrent depressive symptom severity,’ lead author Dr Deepika Goyal said.

The researchers recommend women with a history of depression who are in the final stage of their pregnancies during the short daylight months use light boxes.

This involves sitting in front of a light-emitting box for around half-an-hour at the start of each day.

Although evidence of their effectiveness is mixed, light therapy is thought to stimulate the sun’s rays that are missing during the winter months. 

Pregnant women may also benefit from being outside as much as possible.

‘Women should be encouraged to get frequent exposure to daylight throughout their pregnancies to enhance their vitamin D levels and to suppress the hormone melatonin,’ Dr Goyal said.

Melatonin is a hormone that regulates sleep, however, too much has been linked to insomnia and high blood pressure.  

‘Daily walks during daylight hours may be more effective in improving mood than walking inside a shopping mall or using a treadmill in a gym,’ she added.

‘Likewise, early morning or late evening walks may be relaxing but would be less effective in increasing vitamin D exposure or suppressing melatonin.’

Postnatal depression affects more than one in 10 women within a year of giving birth in the US and UK.   

Many experience the ‘baby blues’; when they feel down, teary and anxious within the first two weeks of giving birth.

But postnatal depression occurs when a woman feels persistently sad, tired and withdrawn, as well as struggling to bond with her baby.

As many men may struggle with the condition as women, research suggests. 

This comes after a study released earlier this year suggested singing helps women overcome postnatal depression.

New mothers who struggle with moderate-to-severe symptoms of the condition recover faster if they sing in a group, according to research by the Centre for Performance Science in London.
