Most members will agree that we feel better when the weather is good, like now in the UK .
• Happier outlook. Sunlight seems to have widespread mood-elevating effects, partly because serotonin increases when nights are short and days are long. A type of depression called Seasonal Affective Disorder affects some people during the winter when they don't get enough sunlight - psychiatrists recommend depressed individuals go outside in the sun for half an hour a day whenever possible.
• Improvement of Alzheimer's. Patients exposed to bright lighting during the day do better than those exposed to dim daytime lighting.
• Better sleep. Natural daylight helps shut off your body's production of melatonin, a hormone produced at night that makes you drowsy. This means you're more likely to feel tired at bedtime when it's dark.


• Vitamin D is a fat-soluble vitamin found naturally in cod liver oil and oily fish, added to some foods, and produced in the skin with help from the sun. The skin produces vitamin D at levels of sun exposure below those that cause sunburn. Deficiency causes rickets, osteomalacia, and other disorders. Here levels of sunlight in winter are often so low that vitamin D needs to be supplemented in the diet.


• Protection from other diseases. Exposure to UV rays may help with psoriasis, acne, and lupus, or even improve asthma.
Disadvantages -
• Sunlight contains ultraviolet (UV) rays, the main cause of skin ageing, and can cause skin cancer. It's important to protect skin against sun damage at any age, but take special care with babies, children, young people, and fair skin. A blistering sunburn before the age of 20 increases the risk of malignant melanoma, the most serious type of skin cancer. Use of sunbeds and sunlamps can also increase risk of skin cancers. Numbers of melanoma are rising in most populations with fair skin.
• Excessive sun exposure is a factor in causing cataracts.

Little and often is best in the UK. Total sun protection with high SPF sun cream all the time is not ideal.
Never be red, but the general advice is 5 or 10 minutes of unprotected sun exposure then put on sunscreen ( at least 15 depending on age, skin type, and strength of sunlight ... up to 50 ) and protective clothing .
