5 exercises to improve your vision naturally and relieve eye strain

Eye exercise,Health,Wellness

If you day starts and ends with poring over small type on your smartphone/computer, then you may soon suffer from eye fatigue and eye diseases. In addition to this, smartphones also emit harmful blue light that can even speed up blindness. But there is a lot that can be done to boost your eyesight, including certain helpful exercises and diet modifications.

Eating right can make a lot of difference to your eyesight. Opt for antioxidant-rich foods such as leafy greens, egg yolks, yellow pepper, pumpkin, sweet potatoes, and carrots. Yellow and green vegetables are also helpful in preventing macular generation, which can go on to cause of blindness. Also, include fish in your diet as it is rich in fatty acids, and foods rich in sulphur such as garlic and onions that prevent cataract formation.

Here are 5 exercises for healthy eyes and better eyesight:

* Palming is a helpful exercise that can relieve eye stress and boost eyesight. Rub your palms together to generate heat, and then gently place them against your eyes for a few seconds and repeat 5 times.

* Eye rolling is another beneficial exercise. Start by rolling your eyes a few times in a clockwise direction. Then take a break and roll them in an anti-clockwise direction. Repeat 5 times.

* Refocusing is a good exercise for your eye muscles and is something you can do even at work. At intervals, look away from your screen to the farthest thing/place that you can see. It can be the end of the corridor, the office room or the farthest building you can see from a window. Put your thumb down in front of your eyes, and now focus on the thumb for a few seconds followed by the distant object/place. Repeat 5 times.

* Blinking exercises are also easy to perform and help with eyesight problems. You will need a blank wall and a place to sit. Close your eyes for 2 seconds, then open them and blink rapidly for 5 seconds. Repeat 5 times.

* 20-20-20 rule: If you want 20:20 vision, this exercise can help you. Every 20 minutes, you need to look at something located 20 feet away for 20 seconds.

Simple Leg Exercises Can Reduce Negative Effects On Heart And Blood Vessels

Simple Leg Exercises Can Reduce Negative Effects On Heart And Blood Vessels

Did you know how beneficial are simple leg exercises while lying down? A sedentary lifestyle can cause an impairment of transportation of blood in the body which in turn may increase the risk of diseases in the heart and blood vessels. Performing simple leg exercises can make a huge change and prevent such problems, a new study reveals. Earlier work has demonstrated that prolonged sitting for up to 6 hours results in a decline in both blood flow to the limbs and in our larger arteries’ ability to widen to accommodate increased blood flow.

This is the first study to show that sitting for just 10 minutes is sufficient to reduce blood flow to the legs and impairs the function of small blood vessels supplying muscles in the leg.

This paper also highlights a reduction in the function of small blood vessels when lying down. However, this study suggests that we might be able to reverse this impairment to some extent by performing some simple leg exercises when lying down in bed or on the sofa.

The effects of sitting on blood circulation have been attributed to blood passing more slowly through arteries while sitting. The researchers aimed to find out whether these reductions were caused by sustained sitting, or whether 10 minutes would be sufficient to have a negative effect.

The researchers used a Doppler ultrasound technique alongside the knee to measure blood flow and examined the extent to which blood vessels widened in 18 healthy, young males. These measurements were made prior to and following a 10 -minute period of sitting or during a period of rest while lying down, with or without leg exercises, which were performed by extending the foot back and forth every two seconds for a third of the time spent lying down.

Results showed that a 10 minute period of sitting reduced participants’ ability to rapidly increase blood flow to the lower legs via small blood vessels, but it did not affect the widening of larger arteries in response to increased blood flow. The results also suggest leg exercises can help maintain rapid increases in the blood supply to the limbs.

The study demonstrates changes in blood vessel function measured at the level of the knee. However, the researchers only tested healthy young males and their findings cannot be extended to females. It remains unknown as to how these responses may vary with age, or with people who have heart problems.

Further study may investigate the impact of sitting and inactivity on blood vessels in other places in the body. Studies designed to investigate the impact of repeated bouts of short-term sitting on blood vessel function are needed.

“These findings further our understanding of the negative impact of inactivity on blood vessel function and demonstrate the positive effects of simple leg exercises whilst lying down providing further insight into how inactivity affects vascular health of the lower legs”, says study author Dr Paul Fadel.

The findings appeared in the journal Experimental Physiology.
