On a slightly different tact - how does Ramadan work in countries like Finland say when there is almost no darkness at this time of the year?
Actually whilst I am on the topic of sunshine there is quite a body of evidence that suggests sunlight protects us against several conditions, including depression, heart disease and - believe it or not - some cancers.
Is it possible that by shying away from the sun, we might be doing ourselves more harm than good?
Skin cancer affects about 50,000 Britons every year. The majority of these are basal cell and squamus cell carcinomas. They are usually treatable and rarely life-threatening.
The type of skin cancer which often proves fatal is malignant melanoma. This makes up about 10pc of all skin cancers and kills about 2,000 Britons each year.
Much of the health information regarding limiting sun exposure has been directed at reducing the incidence of melanoma.
There seems to be evidence that burning and/or occasional exposure to intense sunlight, particularly in childhood, tends to increase the risk of melanoma.
However, the relationship between sunlight exposure and melanoma is not as clear as you might think.
For instance, in a study published in 1996 in the medical journal Oncology, men who had most exposure to the sun through their work actually had a reduced risk of melanoma.
The theory is that habitual exposure to sunlight can induce the skin to develop self-protective mechanisms against it. Also, melanoma can often form in parts of the body that are not directly exposed to sunlight, such as the soles of the feet.
This again does not support the link between sunlight exposure and melanoma risk.
While the balance of evidence suggests that to avoid melanoma it is important to protect the skin from intense sun, and particularly burning, how much protection is offered by more extreme avoidance is far from clear.
In addition, even the concept of protecting the skin by using sunscreens is open to question. At least two studies have found that sunscreen use is associated with an increased risk of melanoma.
It may be that although sunscreens help prevent burning, they still allow the transmission of forms of ultraviolet light associated with melanoma.
It therefore seems prudent that when the sun is at its hottest we should avoid it - staying indoors or under a parasol - or wear suitably protective clothing.
Despite all the negative messages we hear about sunlight, it's hard to deny that most us prefer sunny weather. However, its benefits go far deeper than this.
It appears to have a profound effect on mood, and lack of sunlight is thought to be the major factor in a depression which occurs in the darker months, known as seasonal affective disorder (SAD).
Sunlight is also important for the production of vitamin D, a deficiency of which may manifest as increased risk of bone fracture, muscle weakness and immune system problems.
But even more surprising is research that shows that sunlight exposure may actually reduce the risk of certain cancers.
Studies show that a 10 per cent reduction in sunlight exposure leads to an increased incidence of breast cancer of between 6 per cent and 10 per cent, and a 7 per cent to 12 per cent increase in colon cancer cases.
Even if we assume only a 6 per cent rise in each of these two cancers from avoiding sun, this still equates to about 2,000 extra deaths in the UK each year.
Yet reducing sunlight exposure will prevent only a proportion of the 2,000 deaths which occur each year from melanoma.
So while avoiding excessive exposure to sunlight and sunburn may be important, the time has come to recognise the sun's health-giving properties.
