Sitting outside, soaking up the sun and feeling the warmth on your skin can do a wealth of good for your physical and mental health. Critically, without direct sunlight, your body can’t make vitamin D, a crucial chemical which is important for your bones, your muscles and your immune system☀️
Many of us have low levels of vitamin D over winter and this has been linked to a range of diseases, including dementia, autoimmune diseases and diabetes. So to keep healthy we really need to get out there and boost our levels.
But vitamin D isn’t the only benefit of sunshine!
We all know sunshine feels great – that’s because exposure to sunshine boosts your mood by increasing your brain’s release of a hormone called serotonin, which also helps you feel calm and focused.
One study found that people had higher levels of serotonin in their blood on bright days compared to overcast or cloudy ones. They also found that the rate of serotonin production in the brain was directly related to the duration of bright sunlight, regardless of the season or outside temperature. On top of this, there is some research to suggest that direct sunlight can trigger your skin cells to produce endorphins, which also make you feel good😀
It’s true you can get some vitamin D from food, but it’s very difficult to get enough from diet alone. The best food sources are fatty fish, salmon, mackerel and sardines. If you’re vegetarian, there is a little in egg yolk and mushrooms, but eating enough to get all the vitamin D you need would be tough. Luckily, it is far easier to get a daily dose from the great outdoors.
Little and often is the best approach to topping up on sunshine. You may be tempted to soak up all your sunshine in one day, but most vitamin D is made in that early part of being outside. And minimising long exposure times is also the best way to avoid burning.
Take care though if you have sensitive skin or if you’re taking any medication that might make you more sensitive. If you’re using any skincare products that contain retinol or other strong exfoliants, you should always put on sunscreen before you venture outside – these products can affect your sun sensitivity.
