Let there be light!

Today, for the first time this year, Ameba and I played tennis. And it was fantastic - we were outside, on the courts, in T-shirts, the sky was blue and the sun was out - and even warm (our tennis is coming along too!)


Which brings me to today's fact: the sun makes people happier. Fact. 


Working it's magic


According to howstuffworks.com the following is what happens when the sun shines:


One area where humans may not be able to escape the sun's biological effects is on their moods. It all comes down to a complex relationship among sunlight, melatonin and serotonin that we're only just starting to understand.
Melatonin is a hormone that controls sleep, and serotonin in a neurotransmitter that is tied to states of wakefulness and being in a "good mood." Serotonin is the chemical targeted by a class of anti-depressants called SSRIs, which keep higher levels of serotonin in the bloodstream to help elevate mood.
The web connecting sunlight, melatonin and serotonin goes something like this: When the sun comes up again, and sunlight hits the optic nerve, some of that light is sent to the gland in the brain in charge of melatonin. In response, melatonin secretion decreases. When the sun goes down, the body increases its secretion of melatonin.
At the same time, when the body perceives sunlight, serotonin levels increase. And the more sunlight the human body is exposed to, the more serotonin the brain produces [source: ScienceBlog]. So in effect, melatonin and serotonin have an inverse-proportional relationship that is guided by the body's perception of sunlight. The overall effect is "downtime" at night and "uptime" during the day.
There's another factor involved in sunlight's affect on mood, though: vitamin D. The body actually creates its supply of vitamin D from the sun's ultraviolet rays hitting the skin, and high levels of vitamin help the body maintain high levels of serotonin [source: Collinge].

Guess there were quite a few happy people in London today :)

We love you Chewy

Earlier this week we had to make the hardest decision anyone with a pet will ever have to make. You have to be totally selfless, even though you’re fully aware of the devastating consequences. I’m typing this with tears streaming down my checks and my nose running. Over the last few weeks Chewy had slowed down, he wasn’t his beansy self, but we knew this might happen and just took everything slower. On Tuesday we went for our walks, he ate all his food and got as many treats as he could. On Tuesday night, he climbed into our bed. His breathing was heavy, the lymph glands in neck had hugely swollen and he was struggling to breathe. He was disorientated and wouldn’t eat or drink. He kept wanting to go outside, but wasn’t able to stand. I slept next to him on the floor, in the other bedroom and came downstairs when wanted to. Eventually at about 5am we called the vet. She confirmed our worst fears. We booked an appointment for 7:45 that morning, we had a little time to say g

Dining room blues

We'd initially thought to give ourselves some time to live in the house before decorating, you know, to get to know the space and how it'll be used... two months in and the dining room is first up! It's pretty obvious, we're going to be eating in there! It was an easy decision (we both agreed with each other) the walls were going to be a dark blue, both have pretty much floor to ceiling windows next to them, so we weren't too worried about the space feeling dark.  Farrow & Ball's Hague Blue was our first choice... so we got a sample. And samples of Stifkey Blue , Drawing Room Blue and Pitch Blue , you never know what it's going to look like on the wall... although the colour samples are a pretty good indication.   With a sort of naughty-child feeling the sample patches were painted onto the wall. It felt quite rebellious just painting stripes onto the wall, clearly ruining the paint already there. But also quite exciting, taking the first of m

My darling dog has cancer

My darling dog has cancer About two-and-a-half weeks ago, on a Friday evening after the Husband had been away for work for the week, the three of us, He, Chewy and myself were sat on the sofa, having a catch-up. The Husband mentioned that Chewy’s glands (lymph nodes) were really big. A bit of back-story, he eats EVERYTHING! He has a keen eye for what we’ve termed a ‘poopsicle’ and happens to chance upon these seemingly tasty snacks rather regularly on his walks. He’s also partial to stale bread that some unwitting fellow has left out for the birds. Or the remainders of a teenagers discarded dinner. Let’s not mention the rotting snacks the fishermen leave behind during fishing season… I think you understand then, that we often have a dog with a bit of a dodgy tummy*. We’re no strangers to probiotics. So, obviously we squeezed probiotics onto his handcrafted meals, and kept and eye on what was going on. But coupled with the swollen glands, we called the Vet and they r
