Does exercise help human brain to get better

Physical activity and cognitive benefits 

by Kaleem Mohammed, Rph, PhD

                        


Blood and oxygen are essential for our brain and other organs to function well. Appropriate cerebral circulation, the flow of blood through the arteries and veins supplying the brain, is essential for cognitive function. 

Studies have demonstrated increased brain blood volume in the hippocampus ( region of brain associated with memory, emotions and the autonomic nervous system)  following a three-month aerobic exercise intervention, and this increase was associated with improved performance on recognition and spatial memory tasks.

Encouraging physical activity during recess time will most likely improve kid's cognitive performance. 

Cutting screen time and increasing physical activity will have long-term health benefits.

Thyroid health- Quality of Life

  Let's get a TSH blood test for our family and friends Normal serum TSH ranges are higher in the  people age 70 to 80 years ; based on this, higher serum TSH goals may be needed as a patient ages.  The American Thyroid Association (ATA) suggests raising the target serum TSH to 4-6 m IU/L for 70 years-old and up The thyroid is a small, butterfly-shaped hormone-producing gland located at the front of the neck. The thyroid gland secretes two main hormones:  thyroxine (T-4) and triiodothyronine (T-3).   These hormones regulate energy levels, metabolism of fats, proteins and carbohydrates, body temperature, heart rate.  Hypothyroidism happens when the underactive thyroid gland doesn't make enough hormones. Hypothyroidism affects up to 10% of the general population (5% undiagnosed) . A n autoimmune disease called Hashimoto's diseas e where our body  makes antibodies that attack healthy thyroid tissues  is the most common cause of hypothyroidism in soc...

Respiratory syncytial virus (RSV) ---cough

Respiratory syncytial virus (RSV) is a leading cause of severe lower respiratory tract disease in young children. Recent RSV strain in Utah is  causing moderate to severe cough (especially during night), weakness and cold-like symptoms .  RSV infection is sometimes severe and is associated with hospitalization, mechanical ventilation, long-term complications, decreased quality of life, loss of work productivity and patient/caregiver stress.  RSV may cause inflammation and infection of small airways and lungs.  Recovery time usually ranges from 7 to 14 days, but RSV can cause serious disease. RSV combined with increasing flu circulation are keeping some hospitals and pharmacies occupied.  Seventeen states are reporting that more than 80% of beds are full, according to the data. Children’s hospitals in Utah, Arizona, the District of Columbia, Maine, Minnesota, Rhode Island, and Kentucky are almost completely at capacity. RSV can spread when viral droplets from a ...
