Adults lose one-third of their body heat through the head, while young children lose two-thirds of their body heat.

The human brain provides about 750 ml of blood per minute (15% of the blood flowing from the heart to the brain), while in the cold season, the body loses heat, which causes the carotid arteries to constrict and the blood flow to the brain to slow down. It has the following adverse health effects:

  • Outbreaks of chronic diseases
  • Stinging pain
  • Visual and hearing impairment
  • Tears may flow
  • Sleep deprivation
  • Development of underlying neurological diseases
  • Memory loss
  • Decreased ability to work due to stress
  • Loss of a healthy scalp
  • Hair becomes dry and discoloured

Therefore, wearing a hat in winter protects oneself from these diseases.
