We all know dogs are considered man's best friend and now experts have proved the positive effects dogs have on us.

By using heart-rate trackers, sleep quality scores, and body temperature data, we can now uncover the true impact pooches have on humans.

Dr Marsha Chinichian, chief science officer of Mindshine, teamed up with thortful.com, to reveal the psychological and physiological effects dogs have on us, and how you can show your dog you love them.

Research showed that people's quality of sleep improved, their temperature lowered and their heart rate increased, releasing dopamine, all after just 10 minutes of playing with a dog.

In regards to how a dog can lower your temperature by 1℃, Dr Chinichian said: "Your dog can calm your nervous system and release feel good hormones.

"This reduces stress on the body and improves an overall sense of calm."

Playing with a dog also boosts the levels of dopamine in the brain.

The study revealed someone's heart rate increased by 22% during playtime with a dog, which is set to boost your serotonin levels.

A little cuddle before bed with your dog can also improve your sleep by 32%.

Of course, the longer the better, but if you struggle with sleep, like so many do, then perhaps petting a dog might be worth a try.

How to let your dog know that you do really love them

Even though dogs have a psychological and physiological effect on our bodies, how can you show your pooch you love them just as much as they love you.

Use a high-pitched voice: Dogs are easy creatures, so when you keep your sentences shorts, like play, hungry? and walkies, they will usually respond in a good way.

Don’t be scared of using a high-pitched voice, as dogs react better to this than a low voice.

Scratch them behind the ears: Did you know petting your dog softly behind their ears can make their brains release endorphins.

This can help against any pains they might have, and is an intimate way for you to show them some affection.

Do something fun together: Go on a hike, or a run together, anything where you can both build trust.

Teach them tricks and train them while making sure to reward them well.

Make sure to spend some quality time together: Having a quiet, calm moment with your pooch is another way for you to show them affection.

Let them cuddle up to you on the sofa, or the floor, and pet them softly so that they know you are there.

A thortful.com spokesman said: “This research proves that we really are a nation of dog lovers.

"It’s amazing to see that the interaction between people and dogs increases our levels of feel-good hormones and improves our sleep.

"We hope that you use our top tips to let your dog know that we really do love them too!”
