Cons: When sleeping on the back, the tongue obstructs the airways due to gravity, which in turn leads to snoring. Thus, there are more chances of developing sleep apnea.
Cons: Since the hands are up, it may lead to pressure on the nerves in the shoulders and arms. It is also associated with acid reflux. Sleeping on the back increases the risk of sleep apnea, as it leads to snoring problems. Overall, this position is neither healthy nor very comfortable.
Cons: Sleeping on any one side may put pressure on the shoulder. It also worsens wrinkles and leads to sagging breasts. Another disadvantage is the undue strain on some internal organs.
Cons: It can worsen heartburn and wrinkles. Sleeping on this side leads to sagging breasts (blame gravity for this!). It may strain the hand or shoulders as well.
Cons: Sleeping with the arms out puts extra pressure on them, and may lead to a disrupted sleep.
Cons: This position has been adjudged as the worst sleeping position. It leads to more wrinkles and breakouts (the face is sloshed on the pillow), sagging breasts (gravity), and neck strain (constant tilting and twisting). The spine is also not supported, which may lead to back pain.
Cons: This is considered as one of the worst positions to sleep, as it strains the neck and the back. It may also restrict deep breathing, and lead to posture problems.
Cons: Gravity will lead to sagging breasts, and wrinkles may worsen as well.
